1. Have a mod chip of some sort
2. Use the 007/mechassault hack with a memory card
3. Have a PC running linux I can put a HDD into.
Do I have that right? That is just the set-up prior to installing the switch and then flashing the tsop. Once have the switch, then I flash the bios just like any other with a Evox dash CD? I just need to pick what section of the bios to burn to right? top or bottom? DO I have to preflash the TSOP if I use a Mod chip to do the flashing?
Basic situation; I have a cheapmod installed with a 4979.06 already burned on it.
What I would like to do;
- boot with the cheapmod and a Evox dash CD with 512K version of 4979.06 on the CD or HDD.
- Disable the cheapmod, enable the top half of the Tsop and flash with 4979.06 using the evox dash utility.
- Leave the bottom half alone as retail for use with LIVE etc.
Will that work?? I could probably even use a different multi bios if I found something usefull, that way I could have the 4979.06 on the cheapmod (is not flashable at all), a retail (bottom of Tsop) and XXX Bios (top of TSOP). The Cheapmod could be my emergency recovery chip in this situation.
Once I had a mod BIOS on the Tsop the Cheapmod would stay disabled until I had a problem. I would then load Evox/avalaunch on the HDD and proceed with the usuall HDD back-up and larger HDD swap etc..
Thanks for your patience, I just can't gather a clear pictue of the ENTIRE process start to finish from all the misc threads and tutorials.

the problem is the wire that melt and the risk with the mcpx.
i know qe can use 3.3 vcc . but to be more sure not to make fried the mcpx
or to have more heat, can we use a 4 wire switch. in the midle, it would be the a19
, the 2 other end would be the ground and the vcc and the other would be nothing.
we could boot the xbox with the bios of our choice and then put it the nothing position after the boot. like that there would be no electricity going around and no more danger.
i need a confirmation if it would work with no other danger.
thank you

Why not cut the trace (A19) leading from the MXCPU to the flash-chip and then solder the switch(es) on the flash side of the gap?
The reason why we have the switches is that we control the adress bit 19, the MXCPU should not! If it wants to compare the four 256kB bioses then do it, all will be the same. Our tying of the adress-line (low or high) will then not short circuit the output A19 of MXCPU.

I think of cutting the trace near/at the flash chip so that no other chips on the (adress) bus are affected. I have read that Yzo soldered a 4k5 resistor in between the flash chip and the MXCPU in order to reduce the current, but why not just cut it?

I'm Gearing up to do this mod to one of my V1.0s I have laying around.
I was curious if it's possible to set it up with a 2 bank switch with the X2 5032 512K bios in one bank and an Original Bios in the other?
Also if I can use that bios is there a particular version of the Original Bios I should use on the other half?
Also, lordvader, the switch solder points image in your sig is top notch

yep. with a 2 way switch any bios 512k or smaller will work (versions being comptible of course) so x2 5035 will work
for a 1.0 you want retail 4034 (if you have not flashed the TSOP yet just put the switch in frist and flash 512k x2 5035, it will leave the retail untouched on the other side)

That's what I figured just wanted to make sure. It's been almost a year since I flashed anything.
The bios on this particular Xbox has already been flashed with an X2 something or other so I'm going to re-flash the whole thing over again.

Thanks for the help, I got it up and running. it was pretty simple
It was flashed with 1MB 4977 originally... I installed the switch and used raincoat to flash 5035 to one side and I cut an original 4034 in half and flashed that to the other side.
works like a champ

After running with this setup for a few days my LCD-MOD came in so I needed to install a pin headder... Since the switch was soldered straight to the mobo I had to undo it completely to remove it.. one time was more then enough of a hastle.
I clipped the power leads to a dead fan I had and found an extra fan pin header I had laying around...
I hot melted one end to the top of my mobo. So now when I need to remove the mobo for future mods I simply unclip the switch.
The 3 prong fan adapter worked well for a single switch. If I had 2 switches for a 4 way bios i probably would have opted to use a power lead for a flopy drive.

So, let me get this straight. solder a wire to the A19 point and on the middle of the on/on switch. then on the top part i solder one wire to the VCC spot and the bottom to the ground. flip the switch to the ground position and then flash the tsop or flip the switch to the VCC position and then flash?
Oh and I'll be using this switch here: http://www.radioshac...rentPage=family
it really doesn tmatter which postition you use, most folks liek to put the bios they will use the most on the ground side though (due to heat issues with the MCPX) a heatsink can alleviate most of these problems though

Currently most people are following the tutorials on the web site to create a multibios tsop by grounding points A18 & A19. But using this method you cant use the newest multiversion bios and I was unable to get it to work at all with a V1.1 box.
A much better way is to make a switch that switches from A19-->ground & A19-->vcc. This forces the box to only read from half the tsop at a time without comparing different parts of the tsop. The easiest way I have found to connect A19 to vcc is to use this point on the lpc:
(IMG:http://www.xbox-scene.com/imageserver/ownmod/eprommod3xs.jpg)
(pic is from the back of the mobo)
I would suggest flashing the bios for the first time without the switch installed first because once installed (like I said before) the xbox can only read or write to half at a time. Ground will be top half, VCC will be bottom half. But after the switch is fully working you can flash half of the bios at a time with evox. Just boot up the box and have a 512k size bios in c:bios and you can then flash half of your tsop at a time.
I have tried this on both a v1.0 and a v1.1 and both have worked fine just make sure you use the correct original bios for each. I also see no reason why this wouldnt work with a switch on both A18 and A19. Then you could switch to 4 different bios banks and could flash to each bank at a time.
Anyways I hope more people were interested in something like this besides myself.

Glad it worked out for you guys. This makes flashing the tsop just as good as a modchip in my opinion. Once you get this set up properly it would be very hard to completely fuck your tsop. Because if you only relash each half of the tsop at a time if the flash does fuck up you still have the other half to boot from. Then you can reflash the fucked up part. Even if you dont use xbox live this is still a great way to have a multibios tsop because it really is a lot safer to flash half of the tsop at a time.

x2+x2+evox d6+x2 4796
that way if the d6+x2 portion doesn't work you could still boot to the lower half the tsop and then fix the top half.

Damm I've been trying to flash the tsop with a multibios on this damm brand new v1.1 xbox for hours and it still wont work. I got so sick of aligning the chip I solder the damm baster, and it still don't work. I can flash the matrix in mode 4 to matrix_tsop flash bios, but when i reboot in mode 4 or 3 the xbox just boots 3 times and then goes off or stay on with blank screen. Ok Ive tried different d/l or the tsop flash bin and still no good, And I know my xbox boots fine without the chip and a orignal HD. It also boots fine with the evoxd6 color mod on the matrix. I now think the matrix is broken or something! any one had this problem ? I really want to get a multibios on a 1.1 cuz I have 3 v1.1 and only 1 matrix chip :)

I would suggest that one install this switch prior to flashing. Flash half the bios with 007 hack (512k) and the other half stays retail. Perfect for XLIVE users. Would this work if one places a 4976.02 512k bios in the 007 gamesave area?

you cant flash a 1.1's tsop using the matrix mod (only 1.0's)
you either need a 29 pin homebrew for a 1.1 or 007 + memory card hack.
both these have worked for me.

I installed the switch and soldered the write mode jumpers before FLASHING.
I made a 512k 4976.02 bios.
Booted up and used the 007 hack - it flashed perfectly.
1/2 Retail and 1/2 xecuter on the TSOP.
It seems to be getting easier all the time.
It will be almost impossible to F up the TSOP using this method.

Go into more details on what you used, a wiring diagram, more shots of the mobo points, etc. It's not that I can't figure it out on my own (it's just a deviation from the original multibios tsop mod), but I would just feel more comfortable doing it if I started with examples and detailed info ready at hand. And thank's Ant2483, I have been hoping for something like this for awhile now. I raise my glass to you.

Well maybe next time you will read before you flash your bios.
What you need is to have a on <-> on switch like this vcc <-- A19-->ground.
Then you can boot up your xbox, with the x2 bios, and then you should change back your orginal dashboard to xboxdash.xbe and rename the evox-dashboard to evoxdash.xbe.

hehe, i dont think im making any sense
all im asking is.. do i need to add a line under [bios] in evolution x to flash 1/2 my tsop at a time.

I wrote this tutorial a couple weeks ago and submitted it to xbox-scene, but it has yet to be posted. This goes into a lot more detail, but has worked flawlessly....
Use a "Multi" Type Bios in a Dual Booting TSOP
* This mod will not work on a v1.2 xbox because the tsop is only 256K. DO NOT attempt on a v1.2 xbox.
** If you do not already have a flashed tsop I would not recommend doing this modification to your xbox. If you dont know what a flash or a tsop is, just stop, right now.
A Little Background
Alright kiddies, here we go again, another quality (or not) Dummy tutorial from The Dude. But now this is a little more advanced, but not so advanced that even your dumb ass can't figure it out.
So, you would like to flash the xbox tsop, but you want to use a "Multi" Bios along with a retail bios to be able to dual boot. What's a multi bios you may ask? It is a bios that you can use on v1.0, v1.1 and now v1.2 Xboxs. The Executor 4974 and newer are all a multi bios as well as the EvolutionX D.6. Very Convenient for some, but for those of us that would like to use it with a retail bios on our TSOP, it just won't work. Why? We won't go into any huge detail here, but to make a long story short the retail bios and the multi bios are too different to work together. As you should all know by now your xbox tsop is 1024K. Each tsop contains four 256K BIOSs, all alike, or different. When your xbox boots up by default it uses the last 256K of the tsop as the bios, but soon after the xbox "double checks" (lets say) the first 256K of the tsop. If the last and first 256K of the tsop differs too much the xbox will invalidate the bios and the boot will fail. With BIOSs like Executor 4973 and older as well as Evox 2.6, 3.6 and older the xbox had no trouble booting with these BIOSs along with retail because they were "Version Specific" and were very similar to retail. So with all that out of the way, its time to get to work.....
The original method for switching a multi bios tsop was to solder a wire from the A19 test point on the motherboard to a SPST switch, then a wire from that switch to any ground point on the xbox motherboard. By forcing A19 to ground you cause a 0v condition causing the xbox to only be able to see the first two 256K parts of the tsop. A custom bios needs to be created for this purpose. The bios looked like...
Original+Original+Modified+Modified
And of course the Modified bios was a version specific type. When the switch was closed (on) A19 is grounded and the xbox can no longer see the last two 256K parts of the tsop, hence booting the original bios because it uses the last 256K of the tsop that it can see. When the switch is open (off) the xbox can see the entire 1024K of the bios (as normal) booting the modified bios. There would not be a conflict between the last 256K and the first 256K, if you are using a version specific modified bios.
Creating a Dual boot Tsop using an original bios and a multi bios
Tools and Supplies
Soldering iron
Solder
Flux (if necessary)
Desolder Braid (if you're a dip shit)
SPDT Micro Switch (or a big one if you like that)
Wire (thin as possible)
All the damn tools you use to take your xbox apart, if you don't have them by now, or don't know how by now, just stop now.
So now we must have a way to split the xbox tsop in two so when we boot one way or another the xbox can only see one half of the tsop at a time. Before grounding a19 would cause only the first half of the tsop to be visible, but ungrounded the xbox can see the whole tsop. In order for the xbox to only see the Second half of the tsop we must force 3.3v to a19. It is just that easy.
I highly suggest flashing your xbox with a 1024K modified multi bios of your choice first. MAKE SURE YOU REMEMBER WHAT VERSION YOUR ORIGINAL BIOS IS. Whatever method you decide on how to do this is entirely up to you. 007/linux tsop flash is the fastest and easiest; a 29 wire homebrew mod to boot then flash is also a good method. If you don't know how, there are plenty of tutorials out there that show you how to do this. Now that you have your modified bios on the tsop, you should install EvolutionX or another dashboard with the means of flashing the bios easily.
Now we will create a 512K bios because you will eventually only be flashing half of your tsop. Since you already have a modified bios on your xbox you will want to make a 512K original bios. It is VERY important that you use the same type of original bios your xbox originally had. If you have a 256K version of the bios you must copy it once to make a 512K bios.
The simple DOS command for this would be....
copy /b original.bin+orignal.bin original_512K.bin
If you have a 1024K version of the bios you must split it in half. There is a good tutorial on how to do this on xbox-scene using win hex workshop.
Installing the switch
So now you have your SPDT switch and it looks something like this....
Cut yourself 3 pieces of wire probably about 10 inches long (25 centimeters for you European folks) and solder them to the 3 points on the bottom of the switch. You want to solder the center wire to the A19 test point on the motherboard. Now solder either one of the wires on each side to a ground point on the motherboard. The other unsoldered wire you will now solder to Vcc, preferably the big fat point on the LPC. Remember which point on the switch you soldered to either Vcc or Ground. Here is a really stupid looking diagram, but you get the picture. Also two pics of the motherboard showing you were A19, Ground and Vcc should be......
So now you have your switch wired in. If you are confident with your work put your xbox back together, if you're not then leave it so you can easily disassemble after you test it. Mounting the switch is entirely up to you. Once again there are many tutorials floating around on that subject, just be creative. When you power up, boot with the switch in the grounded position to make sure that the first half of the tsop boots your modified bios. Then power off and boot up again with the switch to Vcc and make sure that works. After you have confirmed both ground and Vcc are working, you can now power down and set the switch once again to ground. Hopefully you have EvolutionX or another dashboard you can flash your bios with installed. Do what you have to do to put the bios on the xbox so you can use it to flash the tsop with. Now you have your 512K original bios ready to flash to your xbox and you are booted with A19 grounded. Flash the tsop. Now power off, if it hasn't already done so, and power on with the switch to ground. If it boots the original bios and you see the MS dashboard, you were successful with the flash. Now once again flip the switch so A19 is forced to Vcc to make sure your modified bios is still working. Now you have original MS bios while A19 grounded, and you have your modified bios when A19 is forced to Vcc. You can also force A19 to Vcc and flash the second half of the tsop with a new 512K bios in the same fashion.
A few notes to remember, original BIOSs will not work with an unlocked hard drive. Also Make sure that you have your MS dashboard as xboxdash.xbe and your alternate dash (Evox, nextgen, whatever) named differently (evoxdash.xbe, blah, blah). Make sure also if you have a replacement Hard Disk, that it is in a locked condition, otherwise the retail bios will give you an error. Now you can enjoy your xbox and all of its potential using your modified bios, or you can switch and run the xbox like it is a normal retail xbox. In retail mode you can use xbox live, just make sure you dont use xbox live while using your modified bios.
Alright, now its time for the Thank You
First off thanks to all the xbox homebrew developers around the world, without you none of this would be possible.
Thanks to Jujupinto85 for his original multibios guide, and thanks to Ant2483 for his forum post.
And last but not certainly least, 101^ for putting up with all my paranoid shit for the last month, and all his incredible support.
Sorry for the lack of pics dudes, wasn't quite sure how to put them in, pretty new to this forum deal here.

Hey Dudes,
If you would like some pictures for referance check out the tutorials section under "splitting the tsop 4 ways" by junipero (spelling). That has a great picture of a19 and the ground point. Vcc is your choice, i prefer using the point on the lpc that ant posted at the begging of this thread.
Dumpav, to answer your questions, yes this switch allows you to use an original bios. There is also a tutorial on how to split up a bios using winhex in the same section as junipero's tutorial.

maximilian0017 very good point,
I have had this mod done for about 4 weeks now with no signs of trouble. When originally talking about this mod, i had intended to lift the a19 point of the tsop from the mobo completely and running to vcc which would have been absolutely neccessary to run a resistor. My knowledge of resistors is pretty limited but we had talked about a "10K". Honestly i've never seen one, nor do i really know what kind of current regulation it is rated at. If you can offer any insite or anyone else for that matter it would be much appreciated. Like i said, almost a month with this mod and no signs of trouble yet, but sometimes it is better to be safe than sorry.
On another note, if there are any moderators reading this post, a pdf of this tutorial was submitted to xantium a few weeks ago, if this could be put up in the general tutorial section it would be much appreciated.

xboxlinux,
It sounds to me like your write enable jumpers are not soldered properly. I would also help to know what type of tsop you have and your version of the xbox. As i understand if you have a sharp tsop it requires that you solder an extra wire to make a flash work. If you do not have a sharp tsop, i would check your write enable jumpers again and make sure they are soldered properly.

DUDE, it is my jumper, one of them open for some reason, now I have another problem. I was able to backup my bios and also upload a 512k conbination of the red 4976.02 red bios, this is my result:

I assume it's perfect. I just ran one of the wires to GRND and A19 and solder them on the switch and then Green/RED flashes, but if I turn off the switch open cause I didn't ran the VCC for now just to check I get the M$ bios? If I didn't attach the switch would I get the red/green flashes?

Nice work dudes,
I have gotten a few offers for people to host the full tutorial, and it has been uploaded and a url will be following shortly.
Another note, there have been some concerns that a direct current from vcc to the tsop could cause a little bit of trouble, but after a month with this mod done to a couple of xbox's that i do own, i haven't had any trouble at all. For those of you that want to go the safe route, a small resistor in line from Vcc to the tsop will do the trick. The actual specifications of the resistor needed are unknown at the moment, but when i get some more information i will post as soon as possible.

Great work Ant and Dude. I've wanted to get a multibios going using the standard bios ever since X2 was released but couldn't. I've been using the TACPX Debug Dual bios on the first 512 and a blue C: X2 and red E: X2 on the last 512 with the a18 off a19 switch to change startups. Problem is although TACPX looks standard it can't be used with xbox live. I will change my switch around and flash the first half with a 512 standard bios and see if it works. I'd like to keep the other half the way they are giving me 3 startup choices, I hope it will work. Will post my results.

Here are my findings. When I changed my switch around only the off position would work (bios 4). I re-flashed with 4 x X2 using 007 trick. This gave me 3 X2, 1 x a19 to VCC, 1 x a19 to Ground, 1 x switch off. Using evox I flashed one side with 2 x Original 4034 which was all ok. Then I flashed the other side with red X2 E: + blue X2 C:. The blue X2 worked with a19 to ground but the switch off position didn't work. My guess is each side must have 2 x same bios. If anyone knows another way pls post how it's done.

When you ground a19 it's almost as bad as applying vcc to it.
I would simpely take a resistor and put it in between the switch and a19/18., this way both currents are limited.
As to trying to find the correct value, it would probably be trial and error, try a relatively big one like 100 Ohms first in both situations (a18/19 to ground or vcc), if the switch doesn't work anymore or the x-box chrashes just lower the resistance.
At some time you wil have found a value that everyting seems to work, take about 70% of that and that would be perfect.
(so if it's a 10ohms resistor you found to work, you should use a 7ohms resistor)
Always try to find the maximun resistance first, how higher the resistance that everything works the better(minus the safety ofcource)
At this time i do not have the resources to try this, but i would not do it any other way(as an official techie)
If anyone tries let me know, in the meantime i wil try to think of a more educated guess.
There are also small heatsinks like those on pc motherboard cihpsets, these couldn't hurt also because overcurrent means heat and heat means dead components, so that's a second way to secure your x-box life
That one then goes on the big chip without a cooler on it.

Ok, wel actually the resistance is a lot lower than i thought, probably somewhere in between 10 and 30 ohm's.
Andy Green's (aka Numbnut) notes also gave the same results, if i read it correctly he thinks it would be about 15 ohms.
(p.s. thanks Andy for the great work on the x-box!!!)

yes how many people have had success as in no heat problems?
and I am also stupid on resistors and values and such.. so..
I have a couple 10k ohm 1/4 watt resistors.
I also have 220 but think thats too big or small I don't know lol.
Anyway will the 10k work? as in save something from happening? AND STILL ALLOW TO WORK?
or are we talking resistors that we cannot get at radioshack type of place?
rather be safe then sorry later.. thank you!

I too am confused.. but I beleive it is just typing that is confusing some of us..
10k ohms not 10ohms correct? He stated 101 said 10k and he knows his shit..
but then The_Dude said 10-20 ohms and left out the K so I am assuming 10K..
however I also want to know 1/4 watt or 1/2 watt.. I have asked this before and people have stated it doesn't matter.. there is barely a difference but I say there is .. double the difference.. what entails I don't know but 1/2 is twice as much as 1/4 lol
Anyway 10K 1/4 or 1/2 ??

Hi Chaps
Sorry if this post doesn't quite look right - my first one on the board.
I've followed the tutorial - everything works great, except I made one small change - if you follow the tutorial, then your xbox will be modded when A19 is pulled high, and you'll boot orig bios when it's grounded.
With all the talk of potential heat problems, and resistors, I figured that it's better (at least for me) to flash the bios's the other way round - so you're booting the modded bios when A19 is grounded.
Seems to me that you'll be booting modded more often anyway, so why stress the MCPX?
Also something that I think is missing from the tutorial - the first thing I do when doing the 007 hack is to take a copy of the original bios (raincoat -r orig.bin). You can then split in half using your favourite method and you'll be sure to be flashing the top half of the TSOP with the right image. It's always a nice feeling when you split the orig.bin, take a checksum and it exactly matches on of the ones available on xbins.
Think that's about it - bloody amazing hack, I now have a fully switchable modded xbox for the cost of a switch.

Erm, does this mean that there is still the potential problem with A19 is tied to ground? If so - forget most of my last post!
I'm no electronics expert, but it would confuse the hell out of me if this was the case. If voltage = 0 then surely there's no current or anything... hmmm...
Can someone clarify this?

Title: Multiversion Compatible Tsop Tutorial
Post by: maximilian0017 on June 13, 2003, 03:02:00 AM

Umm, it's not that easy i think
A18/19 are switching all the time between vcc and ground, Every time certain images of the tsop are accessed these switch between the images.
So if you tie A19/18 to Gnd it would sometimes short the Vcc coming from the Mcpx.
And if you tie A19/18 to Vcc it would sometimes short the Gnd coming from the Cpu Mcpx.
So without a resistor the internal a18/19 transistor in the Mcpx will be shorted some of the time, all the switching power of this transistor will be converted to heat trough its internal resistance.
I'll try to find another x-box and try the resistors, ofcourse i'll let you know.
I've got the same problems with free time as "the Dude", but i will try to help.
And don't worry about those 3 people who had their xbox blown, I see a lot of these because i sometimes fix xboxes for people.(p.s. i don't sell modchips, i only repair xboxes)
For the last time:
This is a possible solution for a possible problem so please don't go about it, no one with this mod has the resistors in at this time and almost none of them have problems
The same way of hacking is used for the LPC and the homebrew mods.

One more thing to add,
fur_to_the_third did make a very good point about forcing 0v to the modified bios if that is your primary use. Personally the modified and retail bios share just about the same load on my xbox, because i do have many retail games that are played, so it would not make a difference to me. 0v does seem like the less likely culprit for problem, but if my understanding is correct of electrical signals, ground is still current, just negative current. I would not however mess with the switch while the xbox is on. Turn the xbox off before you plan on flipping the switch because you greatly increase your chance for a short doing that. Any Jackasses out there that think you can launch a game from the hdd using a modified bios, then switch to retail to jump on xbox live will find themselves banned really quick. Xbox live checks the bios you initially booted your xbox on, not the current bios selected.

Max, how do you know they flop from vcc to gnd?
I'd like to help, since I seem to have a v1.0 box and I have quite a bit of electrical engineering background.
we should try and analyze what the chip does under normal operation to figure out how to best lock out the two halves.

we should only switch BIOS if XBOX is TURNED ON ... if we are planning on Flashing the other side of Chip ... right?
For example ... if a started in bios 1 ... and then went to flash the program ... before lauching the actual FLASH ...i could flip the switch ... then FLASH ... and this should be ok ... right?
just a once in a blue moon thing!

no you need to get a switch with 3 legs.. not 2
left leg = gnd
middle leg = a19
right leg = vcc +5
of course vise versa lol as long as a19 is in the middle and other 2 on their own leg.. you are set.

rgtaa to answer your question, yes it is ok to flip while the xbox is on, just don't make a habbit of it. If you've got obsessive compulsive disorder, don't keep flipping the switch for no reason at all. And second, ruffles, you're all fucked up dude. YOu do it that way you'll have one confused damn tsop. You need an SPDT switch, your picture there is a SPST. SPDT = Single Pole Double Throw, you pic is i understand is a Single Pole Single Throw. SPDT basically closes the switch in both positions while the SPST is closed/open. Last i belive vcc is 3.3v not 5v if you are tapping the lpc.

rqtaa:
if you were to use that switch with the outer points it would react like it should.
if you were to use that switch with the center off point the xbox would react like an unmodded xbox and boot the 4th bios image,
I'm pretty sure this would get you banned using xbox live.
On the other hand, it wouldn't strain the MCPX, something that is discussed at this time.

so center position would not be Whole One Meg Tsop?
if in Center position ...why would it only Look at only 4th bios image .... since my switch would be for 2 516k bios? (vcc,a19,gnd)
I'm trying to understand this...
I was hoping if in Center Position I could flash WHOLE TSOP ... if I wanted to ..... but ... is this the case ....
That would allow me to only flash 1/2 for LIVE ... if I wanted to ...and most of the time ... just leave full TSOP ... safe! (not having to worry about heat issues)... with regular 1 meg evol x bios on it .... (since i'm not on LIVE at the moment)
What do you guys think?
Would be easy to flash just prior to going on LIVE!

how about only flashing 1/2 TSOP at time ...but making both evolx then putting switch in Center Position to Save components ...
if so ...would the wiring still be the same vcc,a19,gnd ... or not?
then if I wanted to play LIVE just flash 1/2 with Live! otherwise just leave both sides evolx ... with switch in center position ...

i just wired up a box but didnt use the ground taht guy did, i used the ground on the lpc (the square looking pad) and i used teh same 5v vcc thing. is that ok?, it should be.. also, i dont think we REALLY need to use a resistor becaseu the bios are only loaded off the TSOP instantly to the ram so i dont think its gonna put enough stress on the chip to fry it or somesuch. are there 2 a19 points? and does it matter which one i use... also, im gonna install the switch to split the TSOP in half tomorrow its already flashed with evox 4976.02 or waht ever # they are(i know it ends in .02) and has evox running. can i just flash the TSOP from evox with half d.6 half regular ones then solder teh switch on?

Thanks for the reply... so we have a way ... to have it all!
center 1 meg TSOP
Right 1/2
Left 1/2
and if any are concerned about component heat issues ... keep in center position until we straighten it out ... playing LIVE only when needed by Flashing 1/2 (which 1/2 again vcc to a19 side or gnd to a19 to avoid being banned?
Remembering to flash only 1/2 at a time ... to insure if BAD flash ... you can use the other 1/2 to fix the bad half!
Now I will go to Radio Shack and get the SPDT center swtich OFF ONES!
And thanks alot for Updating the Picture with everything on it! Looks good!
Would the Square LCP in the pic be a better GND point as the other guy says ... then it would look real easy to do!

Hey rtgaa,
I really dont know what would happen if you flash the tsop and then use it with the a19 switch in the middle.
It would probably try to load the 4th bios image, but maby it will fail because the other images are different.
(you could try without problems, as long as you do not load the ms dashboard live settings and games with the "special" bios(you would probablyget banned from live))
And SNAPS!, what do you mean?, if those switches have an off position they always do nothing

If I then wanted to flip switch to other side that would be evolx bios.
and if I wasn't gonna be on LIVE for a while ... I could reflash that side with evolx and switch back to middle position ... SAFE MODE!
This is just a precaution ...and switchs are same price as other type ... and adds a little more flexibity.
HERE is the LINK to what I am taking about!

There is one problem with what rgtaa is saying that may screw people up. If the switch is in the true off (open) position, the xbox will not boot if you have two different bios's in either half of the tsop. And even on top of that i do not even see a need for the switch. Why would you want to flip the switch every time you power up your xbox. OR even more of a pain in the ass would be booting up the xbox, then flipping off (if you're afraid the big bad vcc will burn up your tsop and your chances are slip and none) then you use the IN GAME RESET feature????? What bios will it boot on reboot? NOTHING because you have a combination of death with two different bios's conflicting, so bascially your really handy IGR feature has just become worthless.

i hope i was clear that it's just an option ... and for me ...a good one.
i stated in my Last message ...same bios on both ... i have 4976.02 loaded and turned off all in game resets .... because TON's of people have problems with it ... the BIOS itself has the RESET feature ...and works with everygame and program. (Matrix and a few other games didn't work if system settings had irg turned on ... so i turned it off and found out IRG still works)
I'm not on LIVE at moment ... so after 007 flash with 1 meg bios...it works no problem... and if someone decides to do safe flash ... do 1/2 at a time ... to insure recovery ... and you can test new bioses.
if you are on LIVE 1/2 the time ... then you are right ... center position won't be used ... so ...just switch between the Left and Right sides (how would anyone have a problem with that...since the switch i'm talking about is the same as regular one with an EXTRA feature... if you don't want to use CENTER OFF feature don't use it! ).
But for me ... without LIVE ... and also until Heat issues are straigthened out ... I'll leave in Center Position ... and not give it another worry.
To me it's just the 2 saftey features I need ...
1) if i reflash ... i do only 1/2 at time and recover useing other 1/2.
2) possible strain on conponents if left on Right or Left Side over extended periods of time or many months... until we figure out safe resistance.
P.S. you could load 2 diferent bios's on it ...put in center position and it will appear to be broken ... and discourage others from using your xbox (or knowing what's on your xbox) or kids playing with it ... without your approval...Then flip it to either side to do LIVE or EVOLx

Hey Dudes....
Did a little more research on the topic of resistors and which ones to use if any at all, and IMHO i dont' think they are needed at all. According to a few reliable sources it appears the chances of the tsop and/or the mcpx behing damaged because of this mod is slim to none. You do not run any greater a risk "burning" anything up in your xbox with this mod than any other mod you can do to it. Remember kids, any time you do any kind of modification to your xbox you always run the risk of it being damaged no matter how carefull or how many precautions you do take.
Another exciting note, now that the 007 game save hack has been modified to use evox, and there is an xbins release of this game save, this should make lives a lot easier now with a gui interface rather than command line with the "old" 007/Linux tsop flashing method. It seems this method is by far the most popular now for flashing the tsop. You can open your xbox, solder your write enable jumpers and install your switch all at the same time, include a 512KB modified bios of your choice in the game save and flash.
If i get enough demand for a tutorial including the 007/evox flash method, i will rewrite the tutorial to include flashing.
Good Luck everyone, and keep posting your results, including problems if any.

I had my TSOP flashed with a modifed X2 bios.
I installed this switch and I can get it to switch between 2 hacked bios's but I can not seem to install any retail bios (gotten off IRC). When it flashes one of them and reboots. The system just comes on and off like 3 times then just flashes. I flip the switch and it goes right back to X2. I no longer have my original bios. Is there any way of obtaining a new one? I am pretty sure its a v1.1 xbox system.
Thanks

I rewrote the tutorial to include first time flash with the 007/evox gamesave hack that can now be found "preassembled" at #xbins. This guide is a little more in depth and also includes pics of the write access jumpers that must be soldered in order to flash the tsop.

That perhaps it would be better to use the 3.3v spot instead of the 5v. Any thoughts on this? I want to do this switch, but I would like to choose the best way of doing it.

Thanks for the guide... Ive read this guide and others on xboxhacker.net but Im still a little confused...
Ive got that you put a19 in the middle of the switch. one side of the switch to ground, the other side to VCC.. What is VCC?? is this Point a18 on the Mother board?..also do you have to fip the mb over to get to the ground? what is the #32 point?
thanks!

VCC, in this case, is a unipolar input signals or plainly positive voltage. VCC is not point 18, looking at the picture in the first post, it's point 32 which is +5V. Though I really suggest you use +3.3V rather than the +5V. Follow the link on Sirwill's post to see details.
And no, you don't have to flip the MB over to find the ground (GND). There's a lot of groundpoint on the mobo both on top and bottom. The exposed portion of the screw holes are all ground. But you have to flip the mobo anyways to get to A19, unless you can find a corresponding point on top.

1st) I did just that, I traced A19 to pin 1 on the flash rom. There is a via on the top of the board that is the same size as D0 that you can use or you can use Pin 1 on the Flash rom. Those all go to A19. So that brings me to the next question. James_Row you are suggesting we use 3.3v instead of 5v. The flash rom has 2 other pins (or more) that connect to 5v already. So obviously the flash ROM operates on 5v. Would it still achieve the same results using less than 5v in to the flash rom?
I've got this all figured out now, I can solder everything on the top of the MOBO instead of having the wires go on the bottom. I know where I'm running the wires, all I need to know for sure is if 3.3v will be enough power in to the rom to cause the effect we are after. (The only reasion I question it is I traced the 5v to pins on both ends of the flash rom. indicating that it operates on 5v.) So does anyone know if it is a 3.3v/5v Flash rom meaning it can operate on either volt level?
Can anyone recomend a minimum gauge wire to use for this? I have some VERY VERY VERY small wire. Used for wire wrap. I just wonder how small is to small. How much juice will be running through these wires? I don't want to melt my wire.

Hey, props to you for finding an alternative A19 point on top.
Connecting VCC to A19 is not for the purpose of powering up the chip. It's to signal the chip to address only half of the TSOP and I'm almost pretty sure that it would even operate on a much lower voltage. In electronics world, excess voltage would transform directly to heat, and you wouldn't want that extra heat to go to your MCPX chip, which, as it is current, is already too hot. I've done this on several xboxes already and it worked quite well. As a matter of fact, I flashed the TSOP using a cheapMod and I knew a lot of people are asking how they can use the cheapMod to flash their TSOP. I'd write a tutorial on it as soon as I find a time but that's an etirely different but related story.
Use +3.3V, anyone knowledgeable in electronics would say the same. Yes, the Flash ROM operates on +5V, infact, X2 uses the same chip (AMD) and operates on +5V too, but that's not what we are after and it's not to power up anything. everything is already powered up, we're just feeding signals here, and we should use the least amount of signal that we can find.
Look at this XBH thread link, Dmos talks about using 3.3V and there's a great picture of where you can find 3.3V from the LPC port.
Another interesting XBH thread which discusses the same. Find numbnut's post, it's the 14th post down, and he discussed the repercussion of forcing the pins high and so forth.
About the wire, gauge 24 should be enough. I find IDE ribbons to be an excellent choice.

Hey Dudes,
James Row does make a good point on using 3.3v as an alternative to 5v. Either one will work. Weather or not one is more "dangerous" to use than the other still remains to be seen. Many MANY people have done this mod using the 5v point on the LPC without one complaint of any failure in either the tsop or the mcpx. I have had this mod done for over two months to a couple xbox's using 5v without any signs of trouble at all. Remember like any other mod you do to your xbox, there is always a risk of damaging something.

Got a few questions:
1. Any original xbox kernel will work (I forgot mine). True or False?
2. 30 Gauge Wire is safe to use. True or False?
3. Since I will use my modded bios a ton more, it should be enabled when the switch is on ground and A19. True or False?
4. It's safe to access xbox live with a multibios tsop. True or False?
Any help would be greatly appreciated.

Hi, I just bought two switches for enabling writing to the tsop and just after having them soldered and screwed onto the chassis, I flipped the switch twice to test it and it crumbled to dust! I figured it must have been a defect so I installed another one (same brand)
and the same thing happened... I am a bit scared now that my switch linking VCC-a19-GND might decide to desintegrate as well with time and cause a short between vcc and GND. Has this happened to anyone else? Is it because the switches are cheap or did I heat them too long or maybe screwed them on too tight?

I flashed the Tsop before I put in the switches with a 1meg bios consisting of 4 256 bios's..X2_4977.bin+X2_4977+xbox.bin+xbox.bin.
I put in the switch gnd---->A19<----5v. I now have bios X2_4977 with the switch one way and original bios with the switch the other way.
Here is the main question, when I boot on the X2_4977 bios I go to evox and try to flash it with a 512kb bios it says (Error File Size Error)
but if I try and flash a 1meg bios it says (Press Y to Flash Bios). I thought with the switch the bios was only (512kb) and therefore you had to flash with a 512kb bios?? Can anyone help me with what I may be doing wrong?I dont want to EVEN try to flash with a 1meg bios I just know I will frag the damn thing LOL
Help please.

Plugged it all back in and flashed the bejesus out of the last two chunks with some x2 4977 action...and shebang, my Matrix modchip is totally redundant and removed now!
Honestly I don't know why this hasn't put modchips out of business. it's not especially difficult, and it's got some failsafe-ness to it since you have two sections you can flash. Cheaper than a chip, more reliable than the bert & ernie exploits...this shit is perfect! Props to the crew that put this one together!

The problem is that you used a BIOS for V1.0 Xboxes on a V1.1. You should use the 4817 available from where you got the file.
And yes, you can boot with your working bank and flip the switch to flash the other bank. You were lucky you only flashed half the TSOP. Let's not hope you won't mess the entire TSOP, make sure to flash the bank with bad BIOS. Never attemp to flash both bank in one session, always test first.

Just a few quick questions?
1) When I flash with my modded BIOS(switched to vcc) will the other half just work when the switch is to gnd? or do I have to do something else?
2) What BIOS should I use for the modded half of the TSOP?
Thanks

1). The other half of the TSOP just works when switched to gnd, you don't have to do anything but flip the switch. that's all there is to it. Also, some people recommend flashing the side switched to gnd with your mod BIOS and leaving the vcc side with retail BIOS, since that is likely to be the one you use most, and you won't be channeling juice through anything when it's on gnd. I imagine it really wouldn't matter too much, especially if you wire to a 3.3v vcc. But just something to consider.
2). Best recommendation I could come up with would be the X2 4977 BIOS. It is the BIOS that auto-patches games that are made with the media check, so you don't have to manually patch the game yourself.

I believe the Evox that came with 007Evox installer has the option to install evox on the HD. You can use that option, before or after flashing. After you're done flashing the TSOP, Evox should boot up.

Exactly. It would be great to have a debug bios(512kb) + X2 4977(256kb) + retail(256kb) on Xbox with no modchip and modded so easy. As i see it's very easy to split TSOP onto a 2 parts, but how to split it onto a 4 (as for me, it would be 3) parts with multibios? Can someone support some good pictures (where to solder wires to mobo and what switches to use)? I would be very grateful, and everyone else would be too . Thanks in advance.

ok, i did everything as shown here, i flashed with half retail (pulled right out of the bios bank befor ei flashed with raincoat) and half 4977, i can boot to the 4977 banks fine, but the original banks give me reboot reboot frag, any reason? i think whats happening is the retail bios somehow "knows" the other bios is there and wont boot, cuz first i flashed the bottom half with retail (using 007 raincoat), and it fragged, i thought i had a bad flash, cuz i flashed with 512 using raintcoat, so i booted to evox (since 4977 worked) and tried to reflash the bottom half, but i accidently flashed the top half, lol, so now it was 100% retail bios, and it booted fine with the swith in either position, so then i reflashed with 007 raincoat using a 1meg bios already split as mentioned above
this is a 1.1
oh yeah, got bottom flashed with 4977, and top flashed with retail at the moment

in my experience, you don't really need to flash with retail to begin with. you just need to flash with your mod bios on one half or the other, the other half will already have your retail bios on it, since that's the way it started off anyway.

yeah i agree that is pointless but why 2 why not 4
Orig(Of the shelf)+4977 (evoX)+cromwell (linuX)+Orig (with XBlive)
But hay all i need is someone to conferme this that would be a great help using a ON><ON 3 pinned switch
First Switch
Pin 1 - GRD
Pin 2 - A18
Pin 3 - VCC
Second Switch
Pin 1 - GRD
Pin 2 - A19
Pin 3 - VCC

There is a great tutorial right in this very forum about splitting your TSOP 4 way, not 3, not 2, but 4 way. One more caveat still, you can only use BIOSes made for specific version of Xboxes, no multiversion, thus, anything newer than X2_4973 is not possible to use. AND, certain combination of switch would mean FRAG.
There's a reason why you can only use 2 multiversion BIOSes, as well as why only a specific version BIOS is useable on a 4 way configuration, but I'll leave that up for you to research. The info is there.

i had already flashed with 4977, then was adding the switch after i found this tut, im gonna try reflashign the whole thing retail and the flashing half hacked, but im 99% sure i will have the same problem, retail wont let it boot when there is 4977 present, does ANYONE and ANY idea why it might be doiing this?

I think I'm gonna give it a try Ginie66, and I'll let You know it. Now I'm wondering what configuration of switches will I have to use to have 512, 256, 256 banks 
. Is it even possible? It's very l8 in my country now, and I'm barely thinking, so this problem is bigger than me .

You'll need a 3-position switch on A18. This is wired in the same way as the diagram (Vcc - A18 - GND) but in the centre-position the A18 wire is not connected to Vcc or GND, but is instead left under Xbox control.
Your bank-switch configuration is now as follows (Off=GND, On=Vcc):-
A18 off, A19 off - 256K bank 1
A18 on, A19 off - 256K bank 2
A18 mid, A19 off - 512K bank 1+2
A18 off, A19 on - 256K bank 3
A18 on, A19 on - 256K bank 4
A18 mid, A19 on - 512K bank 3+4
If you add a 3-position switch to A19, you also get the following weird combos:-
A18 off, A19 mid - 512K bank 1+3
A18 on, A19 mid - 512K bank 2+4
A18 mid, A19 mid - 1024K bank 1+2+3+4
As you can see, apart from the 1024K option this ain't much use, unless you've got a BIOS that's split, for example, TATX (1st half)+EvoX D.6+TATX (2nd half)+X2 4977!

Let me tell ya . I flashed my TSOP with retail+X2 4977 1 MB bios file. What i have when i switch (for example) off A19, and switch off A18? EvoX shows, that I have Original 4034 bios and 4977 kernel ;D. Many funny combinations I have up there . Maybe it's possible to boot a 4034 kernel and 4977 bios. I'm going to check it out . Did you think about playing Live that way ? I'll report every combination which I will get in a few minutes . Stay tuned, heh .

. People, don't even try to have a 4 way split. I switched off A18, and switched on A19. What did I get? A smoke... Damned . At least you know, what not to do. On the backside of mobo i saw that A19 wire has desoldered (disconnected ?) and I think it touched the protecting sheet. Now my Xbox behaves just like when d0 is grounded. 3 reboots and it flashes red/green. Any idea how to fix it, or anyone wants to buy me another Xbox? :/
Now I'm asking myself is it because of that wire, or you can't put switches in that position? I know that it may frightened you, but if anyone can verify my mistake, I would be grateful.
-------------------------------------
I didn't want to add a new post, but I want to share my experience. Actually... 4 way split works. I don't know how is it possible that I've had 4034 bios and 4977 kernel at the same time. Now, as I fixed my Xbox (VCC was touching one of LPC points ) it doesn't work like that. It really boots the 4th bank (A18 off, A19 off).
I'm gonna find out how did I do that.

When you switched the A19 wire on, because it was grounded you've probably burnt out a track somewhere.
To fix it, try this:-
Use a multimeter to verify that the original point no longer has Vcc on it (in other words, you've killed it)
Find an alternative connection on the board that has Vcc on it (from the LPC port, for example, although make sure you pick the right supply - there are both 3.3V and 5V supplies there!)
Use the multimeter to verify that this point still has still got Vcc on it (just in case it'd fed from the "dead" side of the damaged track
Join this new Vcc to the one you've killed
This should bridge around the smoked-out track, getting your Xbox back to normal. Be more careful when soldering next time. Try gently lifting the PCB a bit, using the wire. If it comes away in your hand, you didn't solder it properly. If the PCB starts to rise, you should be OK.
Good luck!

Well after lots of reading I've finally did it. (used the dude's guide). Wired the switch to a19, ground, and 5volt vcc. Everything booted ok no prob. I used the 007_With_Evox_Installer.zip with the Evox 2.6 ejectfix 1.0 bios(converted it to 512k) ,and transferred it to a madcatz mem card. etc from the guide.
got Evox menu to boot up...In settings checked my original bios :
Bios Version 4034
kernel 1.00.4034.01
Went ahead and flashed with the new bios. Worked like a charm.
Went back in 007 booted up evox, checked settings
new info
Bios Version Evox 2.6 EjFix...
Now here is the problem
I flipped the switch to a19 position and rebooted. Went back to evox to check the bios and it still said
Bios version EvoX 2.6.
tried again..same thing..
What I'm wondering now is if one of the wires got disconnected during reassembly, but if it still stayed in the vcc positin or vice versa, therefore only flashing half the bios and the other is untapped because one of the wires is disconnected?
If I did a really shitty solder job and flashed the one meg chip with the 512 what would happen?
Did I loose my original bios completely now?
I will get a multimeter tommorow and test the connects.
Any ideas are welcome.

Well I took it apart again, melted/burnt tape..and wire completely bare. I used 20gauge wire for the vcc and ground this time. The a19 wire is still kynar. I figured out what I did wrong, Half asleep careless error. I put ground in the center instead of a19.
Works great now!

Hi everyone. I want to put a switch on the flash jumpers, but the top one is a pain to solder. Is there a problem just installing a switch on the bottom jumper? If I leave only one permanent and the other switchable could the tsop still be inadvertently flashed or will this setup cause a malfunction in the xbox? Hope to hear from all you geniuses on this site. Thanks in advance!

I had a little accident just flashing my tsop, no switch, i did the raincoat on my 1.0 xbox and flashed it with a 256K bios, didnt know then that thats not good, my xbox doesnt work at this point, ive looked for help everywhere and someone suggested fixing 2 switches and then switch to the right bank and reflash when the xbox works, my problem is that i have fixed the switch but however i switch the xbox doesnt boot...
i dont know how the flashing procedure works but what i think i have is:
bank1: 256K x2 bios
bank2: 256-512K fucked up original bios
bank3: 512-768K fucked up original bios
bank4: 768-1024K fucked up original bios
if this is the case, shouldnt my switch work for bank1 ??
ive tried to solder in my matrix but that doesnt work either...
anyway, any help would be nice.

yeah, that sounds a little more serious than just having a bad flash on your TSOP. you get any audio or video at all?
what it sounds like to me is your board is toast. or it might be shorting on a solder splash or something like that, possible to recover under close inspection. but that's about the only advice I know to give for that, inspect everything on the board to ensure you didn't accidentally short something out. anybody else?

Hey guyz, i've gone over all possible and impossible solder points, all looking anything but bad..
I will try and explain step by step what happened:
this on an old 1.0 xbox....
1. soldered tsop jumpers like ive done many times before
2. copied the memcard linux 007 gamesave hack to the xbox
3. booted up 007
4. loaded the 007 savehack
5. telnet to xbox, login and shit
6. runs raincoat with a working 256Kb x2 bios
7. rebootes
8. shocked that it didnt work
9. still chocked but now almost crying...
10. checked forums and tutorials, found out that one must use 1000kb bios on 1.0 xboxes...
11. solder on my trusting old matrix
12. doesnt work... the tears are soon coming...
13. figured maybe the matrix for some fucked up reason have lost the bios i flashed 1 year before.
14. reflashes matrix and test it on another xbox, works
15. solder it back on the nonworking xbox, doesnt work...
16. cries
17. find out about switches for selecting different banks, nothing works ...
18...... you tell me what to do and I will..

So now, if I switch A19 between ground and vcc, then my xbox can only see either the beginning 512K or the ending 512K of that BIOS at a time, respectively.
What did the (old) method of grounding A18 and A19 do then? If I understand correctly, the xbox boots the last 256K of the BIOS normally, but it can still see the entire 1MB. Does grounding A18/A19 effectively block the first 768K of BIOS from even being seen?
Now, I also understand that using A18+A19+VCC (is the consensus to use 3.3V now instead of 5V?)+ground is good because you can get 4 256K BIOSes out of the mix. However, I notice that long since this original post, the XECUTOR2 BIOS is now 512K in size as of build #4978.XX (XECUTOR2 BIOS is 512K). Therefore, would it be best to split the BIOS into something like the following? If I got the table wrong then please let me know:
The above table is WRONG. This one should be right:
Of course, I'm assuming that this is worth the trouble for a 512K BIOS. Is the XECUTOR2 a good, feature packed BIOS? I realize that just because it's bigger doesn't mean it's better.
Update2: Now according to the the post at http://forums.xbox-s...ST&f=43&t=94172 , the XECUTOR2 is 1MB. Which is it, 512K or 1MB? I think it's 512KB.
Update3: I read the nfo files for The Phoenix Boot Loader (v1.3) and I realized that I don't need 007 or any other game for that matter to exploit my xbox and flash the TSOP, nor do I need a memory card or action replay. The only real 'trick' that I needed to do was to get the xbox to unlock the hard drive and connect the hard drive to my PC to update the xbox's files, thus exploiting the xbox through the dash's font exploit. It's all here: http://www.maxconsol...=xbox&itemid=87. So now my xbox has te phoenix boot loader on it and is loading a 1MB verison of the X2 4977 from disk. When I used EvoX's 'backup' function, I get a 1MB file of the 3944 bios, so EvoX is obviously backing up the TSOP. So I grounded A19 and ran the 'backup' function again to see if I got a 512KB version of 3944 in my C:backup folder. Nope: still 1MB.
So my question is, is EvoX simply wrapping around the BIOS and thus copying two copies of 512KB of my TSOP into a 1MB file, or did I screw up modding my xbox? I have wires going to A18, A19, ground, and 3.3V. I easily verified that the 3.3V and ground connections are good with my multimeter.
You see, I don't want to flash a 512KB bios to my xbox if the entire 1MB of BIOS is still visible, for obvious reasons (this would cause a FRAG-Flash Red And Green-condition, right?). So I am trying to verify that A19+ground is working. I presently have A18 and VCC hanging loose with tape over the wire ends.
I really wish to get an answer to this next question. I've been waiting for a few months now...
Say my mod did work and only 512KB of my TSOP is visible right now. What happens if I try and flash a 1MB BIOS file to it (a 1MB BIOS file that is actually either 2 or 4 identical 256KB or 512KB BIOSes)? If it wraps around the BIOS or if it fails to write the final 512KB from the source flash file, I should still be good, right? Of course, if my mod failed, then the full 1MB of flash gets written to 1MB of TSOP, no problem.
My final question is why bother flashing the TSOP at all? The Phoenix Boot Loader (PBL) is loading another BIOS anyway. I can load an alternate BIOS from disk with PBL v1.3 by powering on the xbox with the tray open. Finally, I think that next 'official' release of PBL (v1.4) will have USB support so that I can select from a variety of BIOSes upon boot. Update: Well, the boot process doesn't always seem to work with PBL. I'm not talking about the clock problem which causes the xbox to keep rebooting itself. Instead, either the screen goes black after the initial xbox boot process or I see a sort of green wireframe. What gives?
Thanks

I don't get it; he doesn't have the write enable points jumpered on the top of the motherboard. Did he do that mod after this picture was taken? All of this is useless without jumpering those solder points by R7D3 (MCPX RD# to Flash OE#), right?

In reply to XBOX-LINUX post:
"It was suggested to connect A18 and A19 resp. either to GND or to Vcc, to have definitive 1s and 0s, but we cannot recommand this either, because it is quite likely that this will make your MCPX explode!"
I've done this to 50+ boxes and no one has ever complained about their xboxes not working anymore. My own xbox uses this method and it works just fine.. I only use A19 to GND/VCC cause 2*512k is enough for me.
Anyone else have any respons to this? Also at the end of the post it says:
"Because of severe compatibility problems and possible hardware risks, the Xbox Linux project suggests that you do not use this method. If you really need this functionality, please get a modchip with multiple banks."
Did they get bribed by some modmaker?
This really seems funny.. I know the a19 or a18 to ground method is dumb. But the method in this post really works. Never ever has caused any trouble on any box i have used it on.
Give more feedback? Did your mcpx explode?!?.. heh..

From the mod of surface mount resister http://nidek.sakura....es/Image10.html.
We should cut a trace and add a 4.7 K resister to re-connect that trace. To me, it is a very risky thing to do, even I have some solding experience from Audio DIY.
I am thinking about a easier way to have this assurance. My idea is to add this resister between the A19 and the switch. Will this work? Any comment is appreciated.

this is what i know:
1) Change the flash size thing to 0x80000 if u have a 1-meg TSOP, because you've effectively halved its size.
<evox.ini>
ie. Flash = 0xadd5,"Hynix - HY29F080",0x80000
not Flash = 0xadd5,"Hynix - HY29F080",0x100000
It might work without this but I think you should set it with whatever software your using.
2) The reason multiBIOS v1.1 + v1.0 doesn't work without switching for both high and low is cause there are incompatible bootloaders, but it isn't very hard to change it. In fact with info from Paul B.'s guide at xb-linux its possible to change multiver BIOS to V1.0 and vice versa, u can do this instead. (kinda need to swap bootloaders using xb-tool, xbflash, or maybe just versions of xbflash (code it for multiver/w/out 2bl decryption, not as hard as it sounds but most ppl can't do it :-(), maybe look at those keys up the top of 2bl as well? - i dunno, i found it trivial enough when i did it, i might have just been lucky i guess).
3) Thin gauge wire does not matter. It will NOT overheat, melt or cause any damage, unluss your box has a problem. Reason being is heat is proportional to current * resistance, and there's bugger-all of either of those.
4) Use 3.3V if your TSOP can still detect that strength (it can). It doesn't really matter, but its a little safer - and cause it doesn't change states frequently you won't risk corruption, so the standard 5V isn't really necessary.
5) The TSOP is not what risks getting damaged (unluss your really stupid installing). Its whats connecting to the TSOP A19 (i personally believe this won't get damaged this way). When it is, for example, its trying to send high when you've grounded it => short circuit. But this short doesn't last long and ppl have been doing this for so long now without problems, it seems it's ok. Holding high while its supposed to be low shouldn't be any different. (sounds dodgy i know)
6) There is no advantage using a "real" modchip since you no longer risk screwing your xbox when flashing, just so long as theres two working non-official BIOSs :-)

Okay guys, I tried this. Everything went great. I now can boot my v1.1 TSOP with X2 4979 and Original 4817. I also used a switch with a middle "off" position. So I can always boot my modded BIOS then flip switch to the "off" and reflash a whole 1MB BIOS, instead of a 512K. I have teasted this. My only concern is al this talk of resistors. I do not have one in the circuit anywhere. Do I need one? If so what kind, and where do I put it in the circuit? Please let me know ASAP. I do not want to kill my XBOX.

I've read the whole thread and just want to double check for my own sanity a minimal set of things I will need after the write points are soldered/jumpered.
a 512Kb BIOS (probably going with X2)
27 or 30ga wire
SPDT switch
soldering iron
007 AUF exploit (already have)
Should I have anything else?
With all those I solder 3.3v -> A19 <- Gnd to the switch
Boot evox choose flash bios and choose the 512K X2 BIOS and let it reboot.
After that I should have retail+retail+X2+X2? No need to flash the other half at all?
Of course I don't even know what version Xbox I have yet so if it's 1.2 I can only have 1 BIOS anyways.

This procedure worked PERFECTLY! Here's my steps if anyone cares to repeat:
1 - Used Executer Bios Manager v 1.1 to create 512K BIN files of Executer 4979_06 and original MS 3944 BIOSes.
2 - Wired a SPDT switch to Ground <- A19 -> VCC.
3 - The Xbox already had Executer 4977 flashed on the TSOP, so I booted up with the first bank selected on the switch.
4 - FTP'd the BIOS files to c:BIOS on the Xbox HDD.
5 - Selected the Evox Flash BIOS option.
6 - Chose Executer 4979_06 512K BIN and flashed the first bank.
7 - After the Xbox powered off, restarted up into Evox and used ConfigMagic to lock the HDD.
8 - Powered off Xbox, switched to Second bank, booted up Xbox.
8 - Selected the Evox Flash BIOS option.
9 - Chose MS 3944 512K BIN and flashed the second bank.
10 - After the Xbox powered off, restarted up into MS Dash.
No problems, and thankfully because the Xbox had already been modded for a TSOP flash, I didn't need to mess with any 007 exploits.

Please help. I have a 1.1 xbox, and can flash the bios with no problems. I've installed a SPDT switch, connected A19 to center, and Vcc (3.3v) and ground to the other 2 poles.
When I flash my bios with a 512K x2_4977 bios, with the switch grounded, it works fine. But when I turn off the xbox, switch to Vcc, it boots up to the same x2_4977 bios! So I tried to flash the Vcc side of the TSOP with a 512K BLUE_4977 bios, no problem, boots fine with the blue start up screen. But when switched to ground, it also boots to the BLUE bios!
Well, I've checked the connections and the solder points, they all seemed solid and secure. I've checked with a multimeter. Also checked the switch itself, which is fine also.
Can someone please give me some clues?

Is there anything in particular one would need to pay attention to when putting in this ground/A19/VCC TSOP 512KB split switch mod, when there is a modchip (Xecuter v1.1) already installed? Is it safe to connect to VCC on the LPC even though there is a modchip connected to the same pin?
I don't need to be able to flash the TSOP from the X1. I don't want to remove the modchip either. The X1 has an on/off switch. I have 007AUF for the TSOP flashing.
What I'd like to end up with is:
Modchip switch on, TSOP switch either way = Xecuter v1.1
Modchip switch off, TSOP switch on = Xecuter v2 or other
Modchip switch off, TSOP switch off = retail
Is this possible?

To answer my own post, I managed to set it up exactly like that. I can now choose to boot X1, X2 or plain ole 4034. This TSOP flashing stuff is sweet
Had a bitch of a time with the soldering on A19 though, the stiff wire I soldered on pulled the connect point right off the back of the board and lifted the trace with it .. next attempt, followed the trace to a smaller green connect point, tried to solder on some more flexible wire on there, just couldn't get a solid solder bridge in there, aargh..
Then looked at the top side of the board for an alternative A19, found it (close to D0) and soldered my wire there without problems.
Now I'm wondering, why do these tutorials make people take out their boards and solder on the underside when everything one needs for the TSOP switch is right there on top, A19, 3.3V and ground..

I was curious if it's possible to set it up with a 2 bank switch with the X2 5032 512K bios in one bank and an Original Bios in the other?
Also if I can use that bios is there a particular version of the Original Bios I should use on the other half?
Also, lordvader, the switch solder points image in your sig is top notch
Post by: lordvader129 on October 27, 2005, 06:17:00 PM
for a 1.0 you want retail 4034 (if you have not flashed the TSOP yet just put the switch in frist and flash 512k x2 5035, it will leave the retail untouched on the other side)
Post by: twistedsymphony on October 27, 2005, 07:52:00 PM
That's what I figured just wanted to make sure. It's been almost a year since I flashed anything.
The bios on this particular Xbox has already been flashed with an X2 something or other so I'm going to re-flash the whole thing over again.
Post by: FarM_ on October 29, 2005, 05:14:00 AM
I use 1x512 + 2x256 bioses, X25035+Geuxdebug+retail4817.
Everything works fine after i resolder TSOP points and change switches
Post by: twistedsymphony on October 29, 2005, 07:29:00 AM
It was flashed with 1MB 4977 originally... I installed the switch and used raincoat to flash 5035 to one side and I cut an original 4034 in half and flashed that to the other side.
works like a champ
Post by: twistedsymphony on November 03, 2005, 09:35:00 PM
I clipped the power leads to a dead fan I had and found an extra fan pin header I had laying around...
I hot melted one end to the top of my mobo. So now when I need to remove the mobo for future mods I simply unclip the switch.
The 3 prong fan adapter worked well for a single switch. If I had 2 switches for a 4 way bios i probably would have opted to use a power lead for a flopy drive.

So, let me get this straight. solder a wire to the A19 point and on the middle of the on/on switch. then on the top part i solder one wire to the VCC spot and the bottom to the ground. flip the switch to the ground position and then flash the tsop or flip the switch to the VCC position and then flash?
Oh and I'll be using this switch here: http://www.radioshac...rentPage=family
it really doesn tmatter which postition you use, most folks liek to put the bios they will use the most on the ground side though (due to heat issues with the MCPX) a heatsink can alleviate most of these problems though

Post by: Ant2483 on April 23, 2003, 09:53:00 PM
A much better way is to make a switch that switches from A19-->ground & A19-->vcc. This forces the box to only read from half the tsop at a time without comparing different parts of the tsop. The easiest way I have found to connect A19 to vcc is to use this point on the lpc:
(IMG:http://www.xbox-scene.com/imageserver/ownmod/eprommod3xs.jpg)
(pic is from the back of the mobo)
I would suggest flashing the bios for the first time without the switch installed first because once installed (like I said before) the xbox can only read or write to half at a time. Ground will be top half, VCC will be bottom half. But after the switch is fully working you can flash half of the bios at a time with evox. Just boot up the box and have a 512k size bios in c:bios and you can then flash half of your tsop at a time.
I have tried this on both a v1.0 and a v1.1 and both have worked fine just make sure you use the correct original bios for each. I also see no reason why this wouldnt work with a switch on both A18 and A19. Then you could switch to 4 different bios banks and could flash to each bank at a time.
Anyways I hope more people were interested in something like this besides myself.

post your results
I would recomend first testing
x2+x2+evox d6+x2 4796
that way if the d6+x2 portion doesn't work you could still boot to the lower half the tsop and then fix the top half.

I installed the switch and soldered the write mode jumpers before FLASHING.
I made a 512k 4976.02 bios.
Booted up and used the 007 hack - it flashed perfectly.
1/2 Retail and 1/2 xecuter on the TSOP.
It seems to be getting easier all the time.
It will be almost impossible to F up the TSOP using this method.
Nice job Ant!!!

Well maybe next time you will read before you flash your bios.
What you need is to have a on <-> on switch like this vcc <-- A19-->ground.
Then you can boot up your xbox, with the x2 bios, and then you should change back your orginal dashboard to xboxdash.xbe and rename the evox-dashboard to evoxdash.xbe.

now in this thread i see that you need 3 solder points? vcc,ground and A19,
but a switch has 2 solder points, so i dont exactly understand what you have to solder
what i guess is a wire from A19 to ground, then A19 to switch and vcc to switch? am i correct?

Use a "Multi" Type Bios in a Dual Booting TSOP
* This mod will not work on a v1.2 xbox because the tsop is only 256K. DO NOT attempt on a v1.2 xbox.
** If you do not already have a flashed tsop I would not recommend doing this modification to your xbox. If you dont know what a flash or a tsop is, just stop, right now.
A Little Background
Alright kiddies, here we go again, another quality (or not) Dummy tutorial from The Dude. But now this is a little more advanced, but not so advanced that even your dumb ass can't figure it out.
So, you would like to flash the xbox tsop, but you want to use a "Multi" Bios along with a retail bios to be able to dual boot. What's a multi bios you may ask? It is a bios that you can use on v1.0, v1.1 and now v1.2 Xboxs. The Executor 4974 and newer are all a multi bios as well as the EvolutionX D.6. Very Convenient for some, but for those of us that would like to use it with a retail bios on our TSOP, it just won't work. Why? We won't go into any huge detail here, but to make a long story short the retail bios and the multi bios are too different to work together. As you should all know by now your xbox tsop is 1024K. Each tsop contains four 256K BIOSs, all alike, or different. When your xbox boots up by default it uses the last 256K of the tsop as the bios, but soon after the xbox "double checks" (lets say) the first 256K of the tsop. If the last and first 256K of the tsop differs too much the xbox will invalidate the bios and the boot will fail. With BIOSs like Executor 4973 and older as well as Evox 2.6, 3.6 and older the xbox had no trouble booting with these BIOSs along with retail because they were "Version Specific" and were very similar to retail. So with all that out of the way, its time to get to work.....
The original method for switching a multi bios tsop was to solder a wire from the A19 test point on the motherboard to a SPST switch, then a wire from that switch to any ground point on the xbox motherboard. By forcing A19 to ground you cause a 0v condition causing the xbox to only be able to see the first two 256K parts of the tsop. A custom bios needs to be created for this purpose. The bios looked like...
Original+Original+Modified+Modified
And of course the Modified bios was a version specific type. When the switch was closed (on) A19 is grounded and the xbox can no longer see the last two 256K parts of the tsop, hence booting the original bios because it uses the last 256K of the tsop that it can see. When the switch is open (off) the xbox can see the entire 1024K of the bios (as normal) booting the modified bios. There would not be a conflict between the last 256K and the first 256K, if you are using a version specific modified bios.
Creating a Dual boot Tsop using an original bios and a multi bios
Tools and Supplies
Soldering iron
Solder
Flux (if necessary)
Desolder Braid (if you're a dip shit)
SPDT Micro Switch (or a big one if you like that)
Wire (thin as possible)
All the damn tools you use to take your xbox apart, if you don't have them by now, or don't know how by now, just stop now.
So now we must have a way to split the xbox tsop in two so when we boot one way or another the xbox can only see one half of the tsop at a time. Before grounding a19 would cause only the first half of the tsop to be visible, but ungrounded the xbox can see the whole tsop. In order for the xbox to only see the Second half of the tsop we must force 3.3v to a19. It is just that easy.
I highly suggest flashing your xbox with a 1024K modified multi bios of your choice first. MAKE SURE YOU REMEMBER WHAT VERSION YOUR ORIGINAL BIOS IS. Whatever method you decide on how to do this is entirely up to you. 007/linux tsop flash is the fastest and easiest; a 29 wire homebrew mod to boot then flash is also a good method. If you don't know how, there are plenty of tutorials out there that show you how to do this. Now that you have your modified bios on the tsop, you should install EvolutionX or another dashboard with the means of flashing the bios easily.
Now we will create a 512K bios because you will eventually only be flashing half of your tsop. Since you already have a modified bios on your xbox you will want to make a 512K original bios. It is VERY important that you use the same type of original bios your xbox originally had. If you have a 256K version of the bios you must copy it once to make a 512K bios.
The simple DOS command for this would be....
copy /b original.bin+orignal.bin original_512K.bin
If you have a 1024K version of the bios you must split it in half. There is a good tutorial on how to do this on xbox-scene using win hex workshop.
Installing the switch
So now you have your SPDT switch and it looks something like this....
Cut yourself 3 pieces of wire probably about 10 inches long (25 centimeters for you European folks) and solder them to the 3 points on the bottom of the switch. You want to solder the center wire to the A19 test point on the motherboard. Now solder either one of the wires on each side to a ground point on the motherboard. The other unsoldered wire you will now solder to Vcc, preferably the big fat point on the LPC. Remember which point on the switch you soldered to either Vcc or Ground. Here is a really stupid looking diagram, but you get the picture. Also two pics of the motherboard showing you were A19, Ground and Vcc should be......
So now you have your switch wired in. If you are confident with your work put your xbox back together, if you're not then leave it so you can easily disassemble after you test it. Mounting the switch is entirely up to you. Once again there are many tutorials floating around on that subject, just be creative. When you power up, boot with the switch in the grounded position to make sure that the first half of the tsop boots your modified bios. Then power off and boot up again with the switch to Vcc and make sure that works. After you have confirmed both ground and Vcc are working, you can now power down and set the switch once again to ground. Hopefully you have EvolutionX or another dashboard you can flash your bios with installed. Do what you have to do to put the bios on the xbox so you can use it to flash the tsop with. Now you have your 512K original bios ready to flash to your xbox and you are booted with A19 grounded. Flash the tsop. Now power off, if it hasn't already done so, and power on with the switch to ground. If it boots the original bios and you see the MS dashboard, you were successful with the flash. Now once again flip the switch so A19 is forced to Vcc to make sure your modified bios is still working. Now you have original MS bios while A19 grounded, and you have your modified bios when A19 is forced to Vcc. You can also force A19 to Vcc and flash the second half of the tsop with a new 512K bios in the same fashion.
A few notes to remember, original BIOSs will not work with an unlocked hard drive. Also Make sure that you have your MS dashboard as xboxdash.xbe and your alternate dash (Evox, nextgen, whatever) named differently (evoxdash.xbe, blah, blah). Make sure also if you have a replacement Hard Disk, that it is in a locked condition, otherwise the retail bios will give you an error. Now you can enjoy your xbox and all of its potential using your modified bios, or you can switch and run the xbox like it is a normal retail xbox. In retail mode you can use xbox live, just make sure you dont use xbox live while using your modified bios.
Alright, now its time for the Thank You
First off thanks to all the xbox homebrew developers around the world, without you none of this would be possible.

If you would like some pictures for referance check out the tutorials section under "splitting the tsop 4 ways" by junipero (spelling). That has a great picture of a19 and the ground point. Vcc is your choice, i prefer using the point on the lpc that ant posted at the begging of this thread.
Dumpav, to answer your questions, yes this switch allows you to use an original bios. There is also a tutorial on how to split up a bios using winhex in the same section as junipero's tutorial.

I have had this mod done for about 4 weeks now with no signs of trouble. When originally talking about this mod, i had intended to lift the a19 point of the tsop from the mobo completely and running to vcc which would have been absolutely neccessary to run a resistor. My knowledge of resistors is pretty limited but we had talked about a "10K". Honestly i've never seen one, nor do i really know what kind of current regulation it is rated at. If you can offer any insite or anyone else for that matter it would be much appreciated. Like i said, almost a month with this mod and no signs of trouble yet, but sometimes it is better to be safe than sorry.
On another note, if there are any moderators reading this post, a pdf of this tutorial was submitted to xantium a few weeks ago, if this could be put up in the general tutorial section it would be much appreciated.

It sounds to me like your write enable jumpers are not soldered properly. I would also help to know what type of tsop you have and your version of the xbox. As i understand if you have a sharp tsop it requires that you solder an extra wire to make a flash work. If you do not have a sharp tsop, i would check your write enable jumpers again and make sure they are soldered properly.

I assume it's perfect. I just ran one of the wires to GRND and A19 and solder them on the switch and then Green/RED flashes, but if I turn off the switch open cause I didn't ran the VCC for now just to check I get the M$ bios? If I didn't attach the switch would I get the red/green flashes?

I have gotten a few offers for people to host the full tutorial, and it has been uploaded and a url will be following shortly.
Another note, there have been some concerns that a direct current from vcc to the tsop could cause a little bit of trouble, but after a month with this mod done to a couple of xbox's that i do own, i haven't had any trouble at all. For those of you that want to go the safe route, a small resistor in line from Vcc to the tsop will do the trick. The actual specifications of the resistor needed are unknown at the moment, but when i get some more information i will post as soon as possible.

I would simpely take a resistor and put it in between the switch and a19/18., this way both currents are limited.
As to trying to find the correct value, it would probably be trial and error, try a relatively big one like 100 Ohms first in both situations (a18/19 to ground or vcc), if the switch doesn't work anymore or the x-box chrashes just lower the resistance.
At some time you wil have found a value that everyting seems to work, take about 70% of that and that would be perfect.
(so if it's a 10ohms resistor you found to work, you should use a 7ohms resistor)
Always try to find the maximun resistance first, how higher the resistance that everything works the better(minus the safety ofcource)
At this time i do not have the resources to try this, but i would not do it any other way(as an official techie)
If anyone tries let me know, in the meantime i wil try to think of a more educated guess.
There are also small heatsinks like those on pc motherboard cihpsets, these couldn't hurt also because overcurrent means heat and heat means dead components, so that's a second way to secure your x-box life
That one then goes on the big chip without a cooler on it.
Post by: maximilian0017 on June 08, 2003, 01:44:00 PM
Andy Green's (aka Numbnut) notes also gave the same results, if i read it correctly he thinks it would be about 15 ohms.
(p.s. thanks Andy for the great work on the x-box!!!)

... if resistor is not used?
Anyone confirm this?
Interesting info ... has anyone who has multi-bios run into problems ... yet?
or is this just speculation? and possible problem?
Could you post LINKS that refer to this POSSIBLE problem and solution? or Discussion of this ISSUE?
Thanks

and I am also stupid on resistors and values and such.. so..
I have a couple 10k ohm 1/4 watt resistors.
I also have 220 but think thats too big or small I don't know lol.
Anyway will the 10k work? as in save something from happening? AND STILL ALLOW TO WORK?
or are we talking resistors that we cannot get at radioshack type of place?
rather be safe then sorry later.. thank you!

10k ohms not 10ohms correct? He stated 101 said 10k and he knows his shit..
but then The_Dude said 10-20 ohms and left out the K so I am assuming 10K..
however I also want to know 1/4 watt or 1/2 watt.. I have asked this before and people have stated it doesn't matter.. there is barely a difference but I say there is .. double the difference.. what entails I don't know but 1/2 is twice as much as 1/4 lol
Anyway 10K 1/4 or 1/2 ??

Sorry if this post doesn't quite look right - my first one on the board.
I've followed the tutorial - everything works great, except I made one small change - if you follow the tutorial, then your xbox will be modded when A19 is pulled high, and you'll boot orig bios when it's grounded.
With all the talk of potential heat problems, and resistors, I figured that it's better (at least for me) to flash the bios's the other way round - so you're booting the modded bios when A19 is grounded.
Seems to me that you'll be booting modded more often anyway, so why stress the MCPX?
Also something that I think is missing from the tutorial - the first thing I do when doing the 007 hack is to take a copy of the original bios (raincoat -r orig.bin). You can then split in half using your favourite method and you'll be sure to be flashing the top half of the TSOP with the right image. It's always a nice feeling when you split the orig.bin, take a checksum and it exactly matches on of the ones available on xbins.
Think that's about it - bloody amazing hack, I now have a fully switchable modded xbox for the cost of a switch.

Erm, does this mean that there is still the potential problem with A19 is tied to ground? If so - forget most of my last post!
I'm no electronics expert, but it would confuse the hell out of me if this was the case. If voltage = 0 then surely there's no current or anything... hmmm...
Can someone clarify this?
Post by: maximilian0017 on June 13, 2003, 03:02:00 AM
A18/19 are switching all the time between vcc and ground, Every time certain images of the tsop are accessed these switch between the images.
So if you tie A19/18 to Gnd it would sometimes short the Vcc coming from the Mcpx.
And if you tie A19/18 to Vcc it would sometimes short the Gnd coming from the Cpu Mcpx.
So without a resistor the internal a18/19 transistor in the Mcpx will be shorted some of the time, all the switching power of this transistor will be converted to heat trough its internal resistance.
I'll try to find another x-box and try the resistors, ofcourse i'll let you know.
I've got the same problems with free time as "the Dude", but i will try to help.
And don't worry about those 3 people who had their xbox blown, I see a lot of these because i sometimes fix xboxes for people.(p.s. i don't sell modchips, i only repair xboxes)
For the last time:
This is a possible solution for a possible problem so please don't go
about it, no one with this mod has the resistors in at this time and almost none of them have problemsThe same way of hacking is used for the LPC and the homebrew mods.
Post by: The Dude on June 13, 2003, 08:15:00 AM
fur_to_the_third did make a very good point about forcing 0v to the modified bios if that is your primary use. Personally the modified and retail bios share just about the same load on my xbox, because i do have many retail games that are played, so it would not make a difference to me. 0v does seem like the less likely culprit for problem, but if my understanding is correct of electrical signals, ground is still current, just negative current. I would not however mess with the switch while the xbox is on. Turn the xbox off before you plan on flipping the switch because you greatly increase your chance for a short doing that. Any Jackasses out there that think you can launch a game from the hdd using a modified bios, then switch to retail to jump on xbox live will find themselves banned really quick. Xbox live checks the bios you initially booted your xbox on, not the current bios selected.
Post by: IndieRockSteve on June 13, 2003, 08:37:00 AM
I'd like to help, since I seem to have a v1.0 box and I have quite a bit of electrical engineering background.
we should try and analyze what the chip does under normal operation to figure out how to best lock out the two halves.
Post by: rgtaa on June 13, 2003, 08:51:00 AM
For example ... if a started in bios 1 ... and then went to flash the program ... before lauching the actual FLASH ...i could flip the switch ... then FLASH ... and this should be ok ... right?
just a once in a blue moon thing!

no you need to get a switch with 3 legs.. not 2
left leg = gnd
middle leg = a19
right leg = vcc +5
of course vise versa lol as long as a19 is in the middle and other 2 on their own leg.. you are set.

Hopefully we don't have too many complusive types in this Forum ...that spend the day switching back and forth with Xbox ON ... like Russian Roulette! ... although the type that does that... will most likely get the Electric Shock 20,000 volt controller pad instead! P.S. now on to serious question!
In Radio Shack ... i saw a SPDT center off switch ... would this work ...and what happens in center position?
Post by: maximilian0017 on June 13, 2003, 02:52:00 PM
if you were to use that switch with the outer points it would react like it should.
if you were to use that switch with the center off point the xbox would react like an unmodded xbox and boot the 4th bios image,
I'm pretty sure this would get you banned using xbox live.
On the other hand, it wouldn't strain the MCPX, something that is discussed at this time.

if in Center position ...why would it only Look at only 4th bios image .... since my switch would be for 2 516k bios? (vcc,a19,gnd)
I'm trying to understand this...
I was hoping if in Center Position I could flash WHOLE TSOP ... if I wanted to ..... but ... is this the case ....
That would allow me to only flash 1/2 for LIVE ... if I wanted to ...and most of the time ... just leave full TSOP ... safe! (not having to worry about heat issues)... with regular 1 meg evol x bios on it .... (since i'm not on LIVE at the moment)
What do you guys think?
Would be easy to flash just prior to going on LIVE!
Post by: rgtaa on June 13, 2003, 05:34:00 PM
if so ...would the wiring still be the same vcc,a19,gnd ... or not?
then if I wanted to play LIVE just flash 1/2 with Live! otherwise just leave both sides evolx ... with switch in center position ...

Post by: rgtaa on June 14, 2003, 01:08:00 AM
center 1 meg TSOP
Right 1/2
Left 1/2
and if any are concerned about component heat issues ... keep in center position until we straighten it out ... playing LIVE only when needed by Flashing 1/2 (which 1/2 again vcc to a19 side or gnd to a19 to avoid being banned?
Remembering to flash only 1/2 at a time ... to insure if BAD flash ... you can use the other 1/2 to fix the bad half!
Now I will go to Radio Shack and get the SPDT center swtich OFF ONES!
And thanks alot for Updating the Picture with everything on it! Looks good!
Would the Square LCP in the pic be a better GND point as the other guy says ... then it would look real easy to do!

I really dont know what would happen if you flash the tsop and then use it with the a19 switch in the middle.
It would probably try to load the 4th bios image, but maby it will fail because the other images are different.
(you could try without problems, as long as you do not load the ms dashboard live settings and games with the "special" bios(you would probablyget banned from live))
And SNAPS!, what do you mean?, if those switches have an off position they always do nothing

If I then wanted to flip switch to other side that would be evolx bios.
and if I wasn't gonna be on LIVE for a while ... I could reflash that side with evolx and switch back to middle position ... SAFE MODE!
This is just a precaution ...and switchs are same price as other type ... and adds a little more flexibity.

i stated in my Last message ...same bios on both ... i have 4976.02 loaded and turned off all in game resets .... because TON's of people have problems with it ... the BIOS itself has the RESET feature ...and works with everygame and program. (Matrix and a few other games didn't work if system settings had irg turned on ... so i turned it off and found out IRG still works)
I'm not on LIVE at moment ... so after 007 flash with 1 meg bios...it works no problem... and if someone decides to do safe flash ... do 1/2 at a time ... to insure recovery ... and you can test new bioses.
if you are on LIVE 1/2 the time ... then you are right ... center position won't be used ... so ...just switch between the Left and Right sides (how would anyone have a problem with that...since the switch i'm talking about is the same as regular one with an EXTRA feature... if you don't want to use CENTER OFF feature don't use it! ).
But for me ... without LIVE ... and also until Heat issues are straigthened out ... I'll leave in Center Position ... and not give it another worry.
To me it's just the 2 saftey features I need ...
1) if i reflash ... i do only 1/2 at time and recover useing other 1/2.
2) possible strain on conponents if left on Right or Left Side over extended periods of time or many months... until we figure out safe resistance.
P.S. you could load 2 diferent bios's on it ...put in center position and it will appear to be broken ... and discourage others from using your xbox (or knowing what's on your xbox) or kids playing with it ... without your approval...Then flip it to either side to do LIVE or EVOLx

. i think u need to flash with 1024k bios EVEN if its only half (512k). i remember psidoc saying this in athread and he REALLY knows what hes talking about when it comes to this. im pretty sure you want ground as retail and vcc as hacked to prevent being banned.
Post by: The Dude on June 19, 2003, 08:37:00 AM
Did a little more research on the topic of resistors and which ones to use if any at all, and IMHO i dont' think they are needed at all. According to a few reliable sources it appears the chances of the tsop and/or the mcpx behing damaged because of this mod is slim to none. You do not run any greater a risk "burning" anything up in your xbox with this mod than any other mod you can do to it. Remember kids, any time you do any kind of modification to your xbox you always run the risk of it being damaged no matter how carefull or how many precautions you do take.
Another exciting note, now that the 007 game save hack has been modified to use evox, and there is an xbins release of this game save, this should make lives a lot easier now with a gui interface rather than command line with the "old" 007/Linux tsop flashing method. It seems this method is by far the most popular now for flashing the tsop. You can open your xbox, solder your write enable jumpers and install your switch all at the same time, include a 512KB modified bios of your choice in the game save and flash.
If i get enough demand for a tutorial including the 007/evox flash method, i will rewrite the tutorial to include flashing.
Good Luck everyone, and keep posting your results, including problems if any.

Post by: Racer on June 24, 2003, 06:11:00 PM
I installed this switch and I can get it to switch between 2 hacked bios's but I can not seem to install any retail bios (gotten off IRC). When it flashes one of them and reboots. The system just comes on and off like 3 times then just flashes. I flip the switch and it goes right back to X2. I no longer have my original bios. Is there any way of obtaining a new one? I am pretty sure its a v1.1 xbox system.
Thanks
Post by: The Dude on June 25, 2003, 08:30:00 AM
I rewrote the tutorial to include first time flash with the 007/evox gamesave hack that can now be found "preassembled" at #xbins. This guide is a little more in depth and also includes pics of the write access jumpers that must be soldered in order to flash the tsop. The new tutorial can be found at www.valholl.org in the tutorials section. Big thank you to #EvolutionX for hosting the tutorial.

Ive got that you put a19 in the middle of the switch. one side of the switch to ground, the other side to VCC.. What is VCC?? is this Point a18 on the Mother board?..also do you have to fip the mb over to get to the ground? what is the #32 point?

VCC, in this case, is a unipolar input signals or plainly positive voltage. VCC is not point 18, looking at the picture in the first post, it's point 32 which is +5V. Though I really suggest you use +3.3V rather than the +5V. Follow the link on Sirwill's post to see details.
And no, you don't have to flip the MB over to find the ground (GND). There's a lot of groundpoint on the mobo both on top and bottom. The exposed portion of the screw holes are all ground. But you have to flip the mobo anyways to get to A19, unless you can find a corresponding point on top.

1st) I did just that, I traced A19 to pin 1 on the flash rom. There is a via on the top of the board that is the same size as D0 that you can use or you can use Pin 1 on the Flash rom. Those all go to A19. So that brings me to the next question. James_Row you are suggesting we use 3.3v instead of 5v. The flash rom has 2 other pins (or more) that connect to 5v already. So obviously the flash ROM operates on 5v. Would it still achieve the same results using less than 5v in to the flash rom?
I've got this all figured out now, I can solder everything on the top of the MOBO instead of having the wires go on the bottom. I know where I'm running the wires, all I need to know for sure is if 3.3v will be enough power in to the rom to cause the effect we are after. (The only reasion I question it is I traced the 5v to pins on both ends of the flash rom. indicating that it operates on 5v.) So does anyone know if it is a 3.3v/5v Flash rom meaning it can operate on either volt level?
Can anyone recomend a minimum gauge wire to use for this? I have some VERY VERY VERY small wire. Used for wire wrap. I just wonder how small is to small. How much juice will be running through these wires? I don't want to melt my wire.

Post by: james_row on June 30, 2003, 06:29:00 PM
Connecting VCC to A19 is not for the purpose of powering up the chip. It's to signal the chip to address only half of the TSOP and I'm almost pretty sure that it would even operate on a much lower voltage. In electronics world, excess voltage would transform directly to heat, and you wouldn't want that extra heat to go to your MCPX chip, which, as it is current, is already too hot. I've done this on several xboxes already and it worked quite well. As a matter of fact, I flashed the TSOP using a cheapMod and I knew a lot of people are asking how they can use the cheapMod to flash their TSOP. I'd write a tutorial on it as soon as I find a time but that's an etirely different but related story.
Use +3.3V, anyone knowledgeable in electronics would say the same. Yes, the Flash ROM operates on +5V, infact, X2 uses the same chip (AMD) and operates on +5V too, but that's not what we are after and it's not to power up anything. everything is already powered up, we're just feeding signals here, and we should use the least amount of signal that we can find.
Look at this XBH thread link, Dmos talks about using 3.3V and there's a great picture of where you can find 3.3V from the LPC port.
Another interesting XBH thread which discusses the same. Find numbnut's post, it's the 14th post down, and he discussed the repercussion of forcing the pins high and so forth.
About the wire, gauge 24 should be enough. I find IDE ribbons to be an excellent choice.
Post by: The Dude on June 30, 2003, 10:39:00 PM
James Row does make a good point on using 3.3v as an alternative to 5v. Either one will work. Weather or not one is more "dangerous" to use than the other still remains to be seen. Many MANY people have done this mod using the 5v point on the LPC without one complaint of any failure in either the tsop or the mcpx. I have had this mod done for over two months to a couple xbox's using 5v without any signs of trouble at all. Remember like any other mod you do to your xbox, there is always a risk of damaging something.

3. Since I will use my modded bios a ton more, it should be enabled when the switch is on ground and A19. True or False?

one question tho, if i wanted to put a LED in to power on when my X2 bios is loaded where would i have to solder it in at?
thx.
Post by: stcogolin on July 18, 2003, 08:11:00 AM
and the same thing happened... I am a bit scared now that my switch linking VCC-a19-GND might decide to desintegrate as well with time and cause a short between vcc and GND. Has this happened to anyone else? Is it because the switches are cheap or did I heat them too long or maybe screwed them on too tight?

I flashed the Tsop before I put in the switches with a 1meg bios consisting of 4 256 bios's..X2_4977.bin+X2_4977+xbox.bin+xbox.bin.
I put in the switch gnd---->A19<----5v. I now have bios X2_4977 with the switch one way and original bios with the switch the other way.
Here is the main question, when I boot on the X2_4977 bios I go to evox and try to flash it with a 512kb bios it says (Error File Size Error)
but if I try and flash a 1meg bios it says (Press Y to Flash Bios). I thought with the switch the bios was only (512kb) and therefore you had to flash with a 512kb bios?? Can anyone help me with what I may be doing wrong?I dont want to EVEN try to flash with a 1meg bios I just know I will frag the damn thing LOL
Help please.

1st) I did just that, I traced A19 to pin 1 on the flash rom. There is a via on the top of the board that is the same size as D0 that you can use or you can use Pin 1 on the Flash rom. Those all go to A19. So that brings me to the next question. James_Row you are suggesting we use 3.3v instead of 5v. The flash rom has 2 other pins (or more) that connect to 5v already. So obviously the flash ROM operates on 5v. Would it still achieve the same results using less than 5v in to the flash rom? I've got this all figured out now, I can solder everything on the top of the MOBO instead of having the wires go on the bottom. I know where I'm running the wires, all I need to know for sure is if 3.3v will be enough power in to the rom to cause the effect we are after. (The only reasion I question it is I traced the 5v to pins on both ends of the flash rom. indicating that it operates on 5v.) So does anyone know if it is a 3.3v/5v Flash rom meaning it can operate on either volt level? Can anyone recomend a minimum gauge wire to use for this? I have some VERY VERY VERY small wire. Used for wire wrap. I just wonder how small is to small. How much juice will be running through these wires? I don't want to melt my wire. |
does anyone have a picture of this, or a link to a picture? Think it would be great to have all the solder points on top of the mobo for ease of installation...

Plugged it all back in and flashed the bejesus out of the last two chunks with some x2 4977 action...and shebang, my Matrix modchip is totally redundant and removed now!
Honestly I don't know why this hasn't put modchips out of business. it's not especially difficult, and it's got some failsafe-ness to it since you have two sections you can flash. Cheaper than a chip, more reliable than the bert & ernie exploits...this shit is perfect! Props to the crew that put this one together!

The problem is that you used a BIOS for V1.0 Xboxes on a V1.1. You should use the 4817 available from where you got the file.
And yes, you can boot with your working bank and flip the switch to flash the other bank. You were lucky you only flashed half the TSOP. Let's not hope you won't mess the entire TSOP, make sure to flash the bank with bad BIOS. Never attemp to flash both bank in one session, always test first.

1) When I flash with my modded BIOS(switched to vcc) will the other half just work when the switch is to gnd? or do I have to do something else?
2) What BIOS should I use for the modded half of the TSOP?

1). The other half of the TSOP just works when switched to gnd, you don't have to do anything but flip the switch. that's all there is to it. Also, some people recommend flashing the side switched to gnd with your mod BIOS and leaving the vcc side with retail BIOS, since that is likely to be the one you use most, and you won't be channeling juice through anything when it's on gnd. I imagine it really wouldn't matter too much, especially if you wire to a 3.3v vcc. But just something to consider.
2). Best recommendation I could come up with would be the X2 4977 BIOS. It is the BIOS that auto-patches games that are made with the media check, so you don't have to manually patch the game yourself.

Exactly. It would be great to have a debug bios(512kb) + X2 4977(256kb) + retail(256kb) on Xbox with no modchip and modded so easy
. As i see it's very easy to split TSOP onto a 2 parts, but how to split it onto a 4 (as for me, it would be 3) parts with multibios? Can someone support some good pictures (where to solder wires to mobo and what switches to use)? I would be very grateful, and everyone else would be too . Thanks in advance.

in my experience, you don't really need to flash with retail to begin with. you just need to flash with your mod bios on one half or the other, the other half will already have your retail bios on it, since that's the way it started off anyway.

There's a reason why you can only use 2 multiversion BIOSes, as well as why only a specific version BIOS is useable on a 4 way configuration, but I'll leave that up for you to research. The info is there.

You'll need a 3-position switch on A18. This is wired in the same way as the diagram (Vcc - A18 - GND) but in the centre-position the A18 wire is not connected to Vcc or GND, but is instead left under Xbox control.
Your bank-switch configuration is now as follows (Off=GND, On=Vcc):-
A18 off, A19 off - 256K bank 1
A18 on, A19 off - 256K bank 2
A18 mid, A19 off - 512K bank 1+2
A18 off, A19 on - 256K bank 3
A18 on, A19 on - 256K bank 4
A18 mid, A19 on - 512K bank 3+4
If you add a 3-position switch to A19, you also get the following weird combos:-
A18 off, A19 mid - 512K bank 1+3
A18 on, A19 mid - 512K bank 2+4
A18 mid, A19 mid - 1024K bank 1+2+3+4
As you can see, apart from the 1024K option this ain't much use, unless you've got a BIOS that's split, for example, TATX (1st half)+EvoX D.6+TATX (2nd half)+X2 4977!
Post by: A.Z.BEST on August 06, 2003, 12:37:00 PM
Let me tell ya . I flashed my TSOP with retail+X2 4977 1 MB bios file. What i have when i switch (for example) off A19, and switch off A18? EvoX shows, that I have Original 4034 bios and 4977 kernel ;D. Many funny combinations I have up there . Maybe it's possible to boot a 4034 kernel and 4977 bios. I'm going to check it out . Did you think about playing Live that way ? I'll report every combination which I will get in a few minutes . Stay tuned, heh .
Post by: A.Z.BEST on August 06, 2003, 01:09:00 PM
. People, don't even try to have a 4 way split. I switched off A18, and switched on A19. What did I get? A smoke... Damned . At least you know, what not to do. On the backside of mobo i saw that A19 wire has desoldered (disconnected ?) and I think it touched the protecting sheet. Now my Xbox behaves just like when d0 is grounded. 3 reboots and it flashes red/green. Any idea how to fix it, or anyone wants to buy me another Xbox? :/Now I'm asking myself is it because of that wire, or you can't put switches in that position? I know that it may frightened you, but if anyone can verify my mistake, I would be grateful.

I didn't want to add a new post, but I want to share my experience
. Actually... 4 way split works. I don't know how is it possible that I've had 4034 bios and 4977 kernel at the same time. Now, as I fixed my Xbox (VCC was touching one of LPC points ) it doesn't work like that. It really boots the 4th bank (A18 off, A19 off).I'm gonna find out how did I do that

When you switched the A19 wire on, because it was grounded you've probably burnt out a track somewhere.
To fix it, try this:-
Use a multimeter to verify that the original point no longer has Vcc on it (in other words, you've killed it)
Find an alternative connection on the board that has Vcc on it (from the LPC port, for example, although make sure you pick the right supply - there are both 3.3V and 5V supplies there!)
Use the multimeter to verify that this point still has still got Vcc on it (just in case it'd fed from the "dead" side of the damaged track
Join this new Vcc to the one you've killed
This should bridge around the smoked-out track, getting your Xbox back to normal. Be more careful when soldering next time. Try gently lifting the PCB a bit, using the wire. If it comes away in your hand, you didn't solder it properly. If the PCB starts to rise, you should be OK.
Good luck!

got Evox menu to boot up...In settings checked my original bios :
Bios Version 4034
kernel 1.00.4034.01
Went ahead and flashed with the new bios. Worked like a charm.
Went back in 007 booted up evox, checked settings
new info
Bios Version Evox 2.6 EjFix...
Now here is the problem
I flipped the switch to a19 position and rebooted. Went back to evox to check the bios and it still said
Bios version EvoX 2.6.
tried again..same thing..
What I'm wondering now is if one of the wires got disconnected during reassembly, but if it still stayed in the vcc positin or vice versa, therefore only flashing half the bios and the other is untapped because one of the wires is disconnected?
If I did a really shitty solder job and flashed the one meg chip with the 512 what would happen?
Did I loose my original bios completely now?
I will get a multimeter tommorow and test the connects.
Any ideas are welcome.

You were lucky nothing was damaged. I made sure to ring out all the connections with a multimeter before and after soldering to make sure I didn't cross any wires.

bank3: 512-768K fucked up original bios
bank4: 768-1024K fucked up original bios
if this is the case, shouldnt my switch work for bank1 ??

this trick doesnt work for me, what happens is that the fan on the chipset just rotates 2 laps or something and then shuts down. the same happens in any of the four positions i can "switch" between the banks...

what it sounds like to me is your board is toast. or it might be shorting on a solder splash or something like that, possible to recover under close inspection. but that's about the only advice I know to give for that, inspect everything on the board to ensure you didn't accidentally short something out. anybody else?

this bahavior have been constant after the bad bios flash, this means the xbox worked before flashing... so my soldering shouldnt be the problem...
thanx for any ideas/advises etc....
Post by: Puskas on September 14, 2003, 06:45:00 AM
I will try and explain step by step what happened:
this on an old 1.0 xbox....
1. soldered tsop jumpers like ive done many times before
2. copied the memcard linux 007 gamesave hack to the xbox
3. booted up 007
4. loaded the 007 savehack
5. telnet to xbox, login and shit
6. runs raincoat with a working 256Kb x2 bios
7. rebootes
8. shocked that it didnt work
9. still chocked but now almost crying...
10. checked forums and tutorials, found out that one must use 1000kb bios on 1.0 xboxes...
11. solder on my trusting old matrix
12. doesnt work... the tears are soon coming...
13. figured maybe the matrix for some fucked up reason have lost the bios i flashed 1 year before.
14. reflashes matrix and test it on another xbox, works
15. solder it back on the nonworking xbox, doesnt work...
16. cries
17. find out about switches for selecting different banks, nothing works ...
18...... you tell me what to do and I will..

| QUOTE (Ant2483 @ Apr 24 2003, 06:17 AM) |
| Currently most people are following the tutorials on the web site to create a multibios tsop by grounding points A18 & A19. But using this method you cant use the newest multiversion bios and I was unable to get it to work at all with a V1.1 box. A much better way is to make a switch that switches from A19-->ground & A19-->vcc. This forces the box to only read from half the tsop at a time without comparing different parts of the tsop. The easiest way I have found to connect A19 to vcc is to use this point on the lpc: <picture taken out for space reasons, refer to 1st message> I would suggest flashing the bios for the first time without the switch installed first because once installed (like I said before) the xbox can only read or write to half at a time. Ground will be top half, VCC will be bottom half. But after the switch is fully working you can flash half of the bios at a time with evox. Just boot up the box and have a 512k size bios in c:bios and you can then flash half of your tsop at a time. I have tried this on both a v1.0 and a v1.1 and both have worked fine just make sure you use the correct original bios for each. I also see no reason why this wouldnt work with a switch on both A18 and A19. Then you could switch to 4 different bios banks and could flash to each bank at a time. |
So now, if I switch A19 between ground and vcc, then my xbox can only see either the beginning 512K or the ending 512K of that BIOS at a time, respectively.
What did the (old) method of grounding A18 and A19 do then? If I understand correctly, the xbox boots the last 256K of the BIOS normally, but it can still see the entire 1MB. Does grounding A18/A19 effectively block the first 768K of BIOS from even being seen?
Now, I also understand that using A18+A19+VCC (is the consensus to use 3.3V now instead of 5V?)+ground is good because you can get 4 256K BIOSes out of the mix. However, I notice that long since this original post, the XECUTOR2 BIOS is now 512K in size as of build #4978.XX (XECUTOR2 BIOS is 512K). Therefore, would it be best to split the BIOS into something like the following? If I got the table wrong then please let me know:
| CODE |
A18 A19 BIOS ----------------------------------------------------------------------------------------------- Ground Open Beginning 512K of BIOS, for the XECUTOR2 which needs 512K. VCC Ground 3rd 256K of BIOS -> Original BIOS (3944 in my case) Ground Ground 4th 256K of BIOS -> Some other BIOS (Which one?) |
The above table is WRONG. This one should be right:
| CODE |
A19 A18 0 1 2 3 N N X X X X 1024KB, 0+1+2+3 G N X X o o 512 KB, 0+1 G G X o o o 256 KB, 0 G V X o o o 256 KB, 1 V G o o X o 256 KB, 2 V V o o o X 256 KB, 3 V N o o X X 512 KB, 2+3 N G X o X o 512 KB, 0+2 N V o X o X 512 KB, 1+3 |
Of course, I'm assuming that this is worth the trouble for a 512K BIOS. Is the XECUTOR2 a good, feature packed BIOS? I realize that just because it's bigger doesn't mean it's better.
Update2: Now according to the the post at http://forums.xbox-s...ST&f=43&t=94172 , the XECUTOR2 is 1MB. Which is it, 512K or 1MB? I think it's 512KB.
Update3: I read the nfo files for The Phoenix Boot Loader (v1.3) and I realized that I don't need 007 or any other game for that matter to exploit my xbox and flash the TSOP, nor do I need a memory card or action replay. The only real 'trick' that I needed to do was to get the xbox to unlock the hard drive and connect the hard drive to my PC to update the xbox's files, thus exploiting the xbox through the dash's font exploit. It's all here: http://www.maxconsol...=xbox&itemid=87. So now my xbox has te phoenix boot loader on it and is loading a 1MB verison of the X2 4977 from disk. When I used EvoX's 'backup' function, I get a 1MB file of the 3944 bios, so EvoX is obviously backing up the TSOP. So I grounded A19 and ran the 'backup' function again to see if I got a 512KB version of 3944 in my C:backup folder. Nope: still 1MB.
So my question is, is EvoX simply wrapping around the BIOS and thus copying two copies of 512KB of my TSOP into a 1MB file, or did I screw up modding my xbox? I have wires going to A18, A19, ground, and 3.3V. I easily verified that the 3.3V and ground connections are good with my multimeter.
You see, I don't want to flash a 512KB bios to my xbox if the entire 1MB of BIOS is still visible, for obvious reasons (this would cause a FRAG-Flash Red And Green-condition, right?). So I am trying to verify that A19+ground is working. I presently have A18 and VCC hanging loose with tape over the wire ends.
I really wish to get an answer to this next question. I've been waiting for a few months now...
Say my mod did work and only 512KB of my TSOP is visible right now. What happens if I try and flash a 1MB BIOS file to it (a 1MB BIOS file that is actually either 2 or 4 identical 256KB or 512KB BIOSes)? If it wraps around the BIOS or if it fails to write the final 512KB from the source flash file, I should still be good, right? Of course, if my mod failed, then the full 1MB of flash gets written to 1MB of TSOP, no problem.
My final question is why bother flashing the TSOP at all? The Phoenix Boot Loader (PBL) is loading another BIOS anyway. I can load an alternate BIOS from disk with PBL v1.3 by powering on the xbox with the tray open. Finally, I think that next 'official' release of PBL (v1.4) will have USB support so that I can select from a variety of BIOSes upon boot. Update: Well, the boot process doesn't always seem to work with PBL. I'm not talking about the clock problem which causes the xbox to keep rebooting itself. Instead, either the screen goes black after the initial xbox boot process or I see a sort of green wireframe. What gives?
Thanks

I don't get it; he doesn't have the write enable points jumpered on the top of the motherboard. Did he do that mod after this picture was taken? All of this is useless without jumpering those solder points by R7D3 (MCPX RD# to Flash OE#), right?

"It was suggested to connect A18 and A19 resp. either to GND or to Vcc, to have definitive 1s and 0s, but we cannot recommand this either, because it is quite likely that this will make your MCPX explode!"
I've done this to 50+ boxes and no one has ever complained about their xboxes not working anymore. My own xbox uses this method and it works just fine.. I only use A19 to GND/VCC cause 2*512k is enough for me.
Anyone else have any respons to this? Also at the end of the post it says:
"Because of severe compatibility problems and possible hardware risks, the Xbox Linux project suggests that you do not use this method. If you really need this functionality, please get a modchip with multiple banks."
Did they get bribed by some modmaker?
This really seems funny.. I know the a19 or a18 to ground method is dumb. But the method in this post really works. Never ever has caused any trouble on any box i have used it on.
Give more feedback? Did your mcpx explode?!?.. heh..

We should cut a trace and add a 4.7 K resister to re-connect that trace. To me, it is a very risky thing to do, even I have some solding experience from Audio DIY.
I am thinking about a easier way to have this assurance. My idea is to add this resister between the A19 and the switch. Will this work? Any comment is appreciated.

Ant2483 I LOVE YOU. i flashed my bios (retail+retail+hacked+hacked) and used the a19>ground a18>ground and only got the hacked bios to work. when i tryed your method works. THANKS ALOT. got live working on hacked xbox (when on retail bios+hdd locked)

1) Change the flash size thing to 0x80000 if u have a 1-meg TSOP, because you've effectively halved its size.
<evox.ini>
ie. Flash = 0xadd5,"Hynix - HY29F080",0x80000
not Flash = 0xadd5,"Hynix - HY29F080",0x100000
It might work without this but I think you should set it with whatever software your using.
2) The reason multiBIOS v1.1 + v1.0 doesn't work without switching for both high and low is cause there are incompatible bootloaders, but it isn't very hard to change it. In fact with info from Paul B.'s guide at xb-linux its possible to change multiver BIOS to V1.0 and vice versa, u can do this instead. (kinda need to swap bootloaders using xb-tool, xbflash, or maybe just versions of xbflash (code it for multiver/w/out 2bl decryption, not as hard as it sounds but most ppl can't do it :-(), maybe look at those keys up the top of 2bl as well? - i dunno, i found it trivial enough when i did it, i might have just been lucky i guess).
3) Thin gauge wire does not matter. It will NOT overheat, melt or cause any damage, unluss your box has a problem. Reason being is heat is proportional to current * resistance, and there's bugger-all of either of those.
4) Use 3.3V if your TSOP can still detect that strength (it can). It doesn't really matter, but its a little safer - and cause it doesn't change states frequently you won't risk corruption, so the standard 5V isn't really necessary.
5) The TSOP is not what risks getting damaged (unluss your really stupid installing). Its whats connecting to the TSOP A19 (i personally believe this won't get damaged this way). When it is, for example, its trying to send high when you've grounded it => short circuit. But this short doesn't last long and ppl have been doing this for so long now without problems, it seems it's ok. Holding high while its supposed to be low shouldn't be any different. (sounds dodgy i know)
6) There is no advantage using a "real" modchip since you no longer risk screwing your xbox when flashing, just so long as theres two working non-official BIOSs :-)

a 512Kb BIOS (probably going with X2)
27 or 30ga wire
SPDT switch
soldering iron
007 AUF exploit (already have)
Should I have anything else?
With all those I solder 3.3v -> A19 <- Gnd to the switch
Boot evox choose flash bios and choose the 512K X2 BIOS and let it reboot.
After that I should have retail+retail+X2+X2? No need to flash the other half at all?
Of course I don't even know what version Xbox I have yet so if it's 1.2 I can only have 1 BIOS anyways.

1 - Used Executer Bios Manager v 1.1 to create 512K BIN files of Executer 4979_06 and original MS 3944 BIOSes.
2 - Wired a SPDT switch to Ground <- A19 -> VCC.
3 - The Xbox already had Executer 4977 flashed on the TSOP, so I booted up with the first bank selected on the switch.
4 - FTP'd the BIOS files to c:BIOS on the Xbox HDD.
5 - Selected the Evox Flash BIOS option.
6 - Chose Executer 4979_06 512K BIN and flashed the first bank.
7 - After the Xbox powered off, restarted up into Evox and used ConfigMagic to lock the HDD.
8 - Powered off Xbox, switched to Second bank, booted up Xbox.
8 - Selected the Evox Flash BIOS option.
9 - Chose MS 3944 512K BIN and flashed the second bank.
10 - After the Xbox powered off, restarted up into MS Dash.
No problems, and thankfully because the Xbox had already been modded for a TSOP flash, I didn't need to mess with any 007 exploits.

When I flash my bios with a 512K x2_4977 bios, with the switch grounded, it works fine. But when I turn off the xbox, switch to Vcc, it boots up to the same x2_4977 bios! So I tried to flash the Vcc side of the TSOP with a 512K BLUE_4977 bios, no problem, boots fine with the blue start up screen. But when switched to ground, it also boots to the BLUE bios!
Well, I've checked the connections and the solder points, they all seemed solid and secure. I've checked with a multimeter. Also checked the switch itself, which is fine also.
Can someone please give me some clues?

I don't need to be able to flash the TSOP from the X1. I don't want to remove the modchip either. The X1 has an on/off switch. I have 007AUF for the TSOP flashing.
What I'd like to end up with is:
Modchip switch on, TSOP switch either way = Xecuter v1.1
Modchip switch off, TSOP switch on = Xecuter v2 or other
Modchip switch off, TSOP switch off = retail
Is this possible?

To answer my own post, I managed to set it up exactly like that. I can now choose to boot X1, X2 or plain ole 4034. This TSOP flashing stuff is sweet
Had a bitch of a time with the soldering on A19 though, the stiff wire I soldered on pulled the connect point right off the back of the board and lifted the trace with it
.. next attempt, followed the trace to a smaller green connect point, tried to solder on some more flexible wire on there, just couldn't get a solid solder bridge in there, aargh..Then looked at the top side of the board for an alternative A19, found it (close to D0) and soldered my wire there without problems.
Now I'm wondering, why do these tutorials make people take out their boards and solder on the underside when everything one needs for the TSOP switch is right there on top, A19, 3.3V and ground..

Yes thats safe.
