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).

You can try if you have a floppy drive.

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

[DeathBringer]

No chances with USB.
