I am trying to bring an xbox back from the grave.The mobo in question is a 1.0v before I started I was getting a 3 boot frag.I noticed alot of trace damage and a handful of missing pieces.I repaired everything I could find which turned the 3 boot frag to a flash green once then flashing red.I know this is an eeprom error so I used this link to restore the eeprom  http://www.llamma.co.../eeprom_fix.htm       and when I booted the xbox it gave me no option and said  "eeprom not flashed" so I switched banks and could now boot off of flashbios 3.0.3 and I flashed 5035 on the other bank of the doux2 which when I boot from the 5035 I have one of three things happen it will either boot to an error9,or it will load the first xecutioner screen then it will shut down power back up get to the same part and the screen will freeze and and the led flashes green/red.Or if I have it on flashbios3.0.3 it gets a dvd drive error 161 and unable to read hdd partition table but I can still use it to flash any bios I want on the chip.What am I missing here?And for what reason would the xbox have problems with how it is getting and receiving information with the ide this is what appears to be the problem by the warning codes on flashbios3.0.3.

My box (also using the 5035) also freezes on the "Live Config Loading" screen with a FRAG if it doesn't like the HDD. You might try swapping that out.

Well I can get past that now until the microsoft x then shuts off and starts back up goes to the same part flashes green/red goes to the error screen which the picture is a little distorted and throws off error13 I can get here now because I found another damaged component and replaced it one of those little black pieces that are on the underside of the board underneath the mcpx chip that have the #330 on it its the same part around all the ram it had half of it knocked off.
I think what I need to do now is try to reprogram the eeprom again when I fixed this component the xbox now reads from the IDE cable and the epprom fix might work now but can someone break that eeprom fix app down for me.When you run the add eeprom exe does your computer screen just suppose to flash a little black box in the middle of the screen and disappear and it be finished doing what it needs to do?
And if the bio bin image is a 256 and I need a 512 for the size bank of my modchip how would I go about doing it?

It may well be that the error 13 really is just an error 13. In that case, you should be able to boot Slayers or similar.

I got the eeprom fix back on there but it still says "eeprom not flashed" this eeprom fix programs documentation says as soon as you boot up it should tell you its flashing the epprom and mine is not doing that.So I must not be doing something right and the only thing I am in the dark about is maybe I didnt patch the eeprom.bin file right.So my question is what is suppose to happen when you run the exe patcher?Or better yet how do you correctly patch the eeprom.bin file?

The xbox wont let me boot from disk it goes straight for the error13

Tell you what I do know and what I dont know.I do know this is mostly an eeprom issue seeing as any bios other than a linux type wont boot just goes into flash green flashing red.The only bios that does not do this is 5035 it will boot to a distorted error13 I can tell at one time or another this eeprom has been messed with but not by me I bought this mobo a couple years back for parts and it has been sitting in a stack until the day before yesterday.There must be something different with the 5035 that gets it straight past the eeprom error but I dont know why.I dont have any 1.0v epproms laying around to swap with so I got to try to atleast get the one it has on it flashed with an image I know to be good this is a must if I ever expect to get the modchip off of it and tsop flash it when I get this problem sorted out.I only use modchips for repairs.

No, wouldn't be XBTool. That doesn't work with the 5035 (which uses an INI file for most settings). The only edit I know of for the BIOS itself is a single byte which determines how it handles the extended partitions (though XBPartitioner's custom partitions makes this redundant).

Are any other parts needed to make the eeprom reader in your sig able to also serve as an eeprom programer? Also can someone point me in the right direction about the reprogramming of the eeprom with this device?
I am lost because I would normally make all eeprom changes with config magic but I cant use it here cause I cant boot to get to it.I dont know how screwed up this eeprom is Ive never ran across one so screwed I couldnt bypass it with a chip.I am still pretty certain with that being said that this is an eeprom issue.I did find an old outdated guide that is kept for historical purposes that seemed like it might work to bypass the epprom using complex debug bios,evox2812,and a couple other tools.
I will give a try in making the eeprom  programer and give that old tut a try and let you all know.

I built the reader but how do I use the reader to reprogram the chip?

[Movax]

Though I doubt this is an eeprom problem, you should try flashbios with embedded eeproms. I think it's in a subfolder of xecuter bioses (xbins). It's basically just flashbios with the ability to flash some generic eeproms from a menu. (Make sure you select the correct eeprom version.)

Of course if you lack the ability to flash the modchip this won't work.

[Bomb Bloke]

Follow the guide exactly as written first in order to read the current contents of the chip.

Once that's done, repeat the process, but instead of pressing the "Read Device" button, open the EEPROM data file you wish to program in and then press the "Write Device" button.

An ancient design for eeprom programmer from the early days of modding , should the PonyProg way fail.

Flash bios does boot I have known that from the start and thats why I think its an eeprom issue.But as I said before this method would not work for me http://llamma.com/xb.../eeprom_fix.htm so I built the reader.But I think I got something wrong it is reading but not correctly.I built the reader first with no power supply and then I rewired a transformer I had laying around made a bridge rectifier with some diodes to turn the ac to dc and the same thing is still happening.I followed the tut to a "t" and I am sure my wiring is right.Pony will not read on the default source settings but if I make the source anywhere after about the third one listed it will read but not correctly all the symbols on the left are "F" and all the symbols on the right are "Y" brfore anyone asks I have tried this setup on 2 other xboxes to the same result.Does anybody have any idea where I am going wrong?

[run088]

I can not get the eeprom reader to work.I know it is exactly like the diagram to the link in bloke's sig.The exact part #'s to a "T" everything.I ran pony as described as well.I am clueless could it be a configeration with my PC?If so what is the correct configuration?

[run088]

Ive tried several different mobos some that I know have a good eeprom and I cant get any reads Ive connected to the lpc as well as the eeprom itself with the same result.Is the xbox suppose to go straight to an orange light when the reader recieves power?With or without an external power supply this is what happens once Im plugged into the pc.
Also I put in a capacitor with my bridge rectifier to help with the concerns you have about the power supply Im sure it is ok really no different than you will find in most power supplys u buy at the store.All you have to do to change voltages on a transformer is either add to the primary wire or take away from the secondary wire but if you take away from the secondary wire u have to watch how much you take off if you take off to much it will run to hot and burn up.The secondary wire is the fat wire that has the lower voltage the primary wire is the thin wire that connects to the higher voltages.Even if there are multible wires the concept is the same u just have to take a multimeter and find each wires matching end to change the voltage. you can run one transformer at several different voltages if it has more than one primary or secondary wire.I  spent a few years of my life building these things this way and I have never had any problems before. I made them for the most part to power walkman radios which need 3v and booklights that ran on 6v.I have made them for other things as well but not like the 2 mentioned. making them for those voltages Ive made hundreds of them.
The only reason I explained how a transformer works is for the benefit of anybody out there interested in knowing how and doesnt Ive never ran across this info anywhere but from text books for electronics and personal experience.
I need to try another pc but my laptop just killed over the other day and I have not got a chance to mess with it yet I think the hdd might have died but not sure yet.
