I have a bios dump made by NSSI which size is 64KB.

If i edit the rom and write it back with Uniflash, will it work (assuming the change in the rom is ok) or will en error or something happen?

What i want to do is bypass the cpuid check in the bios of a socket 7 motherboard.

I think that dump is wrong. Since you know uniflash, you should use it to dump your bios instead ^^

In the meantime, what's your motherboard ? Why do you want to bypass the cpuid check ?

The motherboard is a PB680 430VX. I want to bypass the cpuid check to run AMD k6 cpu with the original AMI Bios, i already tried MR.BIOS and the computer works but i cannot use pci video cards which work with the AMI Bios.

64KB is small for a Socket 7 board, typically they are 128KB ; my guess is that BIOS image is truncated . I would dump using either Uniflash or an AMI flash utility that allows backing up the BIOS .
