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.

so what if u put 2 switchs in so u can boot of 4 bioses

1st     0 0
2nd    0 X
3rd     X 0
4th     X X

can any one verafy this and if so were to solder the 6 points on the mobo

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.

Exactly. I really don't understand why people would go thru all the trouble of flashing the TSOP with exactly the same BIOS. You don't need to do it, never. Just flash half of the TSOP with a hacked one, that's all there is to it really.

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!

[A.Z.BEST]

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 . 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 .

[A.Z.BEST]

. 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!

. One advice how not to fuck up box, when soldering; don't solder when you're tired, when there's almost dark and use some sticky tape to stick that soldered wired to the mobo .
