Bios Mods -The Best BIOS Update and Modification Source

I don't have any and I believe this motherboard is a rare one due to age

I'm sorry, but editing the BIOS is a very dangerous process. There are no guarantees of success.

How about this? https://www.overclockers.com/bios-hot-swapping/

You need other functioning motherboard with same type of BIOS chip: PLCC32
And AMI BIOS.

Or you can buy a hardware programmer for PLCC32:

Are there no other solutions with what I have now? Can't I use another bios chip from another mobo? It was done from the link I embedded earlier. I have another mobo here ga-eg31mf-s2

Other solution - other old CPU for LGA775.
GA-EG31MF-S2 has different type of BIOS chip: SOP8 (soldered).

Hey. What about this manual? https://www.bios-mods.com/bios-recovery/...-recovery/

You can try if you have a floppy drive.

How about flash drive? What name should I give the rom?

No chances with USB.
