screwed banks 1&2 help!!

[dtgorm]

Ok, had everything working fine and somehow i screwed up banks 1 & 2 but banks 3 & 4 work fine.. I want to reflash my bios to where banks 1 & 2 are working again with the latest bios. I have XBMC for my dash and of course evolution is also there...

Problem is, I thought at some time, I originally flashed my bios from scratch using some boot cd which i can no longer find.

How can i restore my bios to the way it was?

if you have the x3 chip use your backup power eject at same time then flash chip

I'm trying to figure out exactly what you have done.
FYI there are 8 * 256K banks.
If you mean switches as "bank" then 1+2 will give you the first 1MB bios storage (bank 1-4).
and "bank" 3+4 (off off on on) will give you the 4th 256K bank (bank 4).
Which could mean you flashed over part of the original bios.

Use the backup bios to reflash your xbox again. Press Power+Eject and you should get a purple X logo.

Flash the X3 bios bios on switch settings (on on off off). Only one you really need...
And when in that bios, you can manage your bios banks and flash them through their using ftp or hard drive. No need go through FlashBIOS again.
