Have a look at the motherboard manual, most motherboards support boot 
block recovery (or at least they used to),  where you can flash a 'dead' 
motherboard by putting a copy of the BIOS on a floppy disk. There is 
usually a bit of firmware on the motherboard that just handles the BIOS 
and floppy drive that enables you to reflash the BIOS with a good ROM 
image, however there is usually no video whilst doing this, just beep 
codes. AMI based BIOS' are reasonably straight forward, and can usually 
be flashed using a ROM file renamed amiboot.rom, Award BIOS' require a 
dos based boot disk, with an autoexec.bat file and the flash utility on too.

Good Luck!!
