I was flashing a new bios onto my P3 motherboard (Via Apollo Pro 133 chipset) and in the middle of the write operation I stood up and trod on the power cord. The power went out and now, of course the board wont POST - just get a long beep, then nothing. I've tried disconnecting everything but the floppy drive and some ram and disabling onboard sound (via jumpers), installing an ISA graphics card with the same result. We have an old device programmer at work (EPROM Burner) and I have the bios files on floppy - but as far as I can tell the burner can't write to the type of EEPROM I have. It is a Winbond W29C020C, which is a 32 pin DIP package, 5.0V program voltage of 256k in size. I could burn the data to a 27256 EPROM instead, but these are only 28 pin devices. Would it work if I burn say a 27C1001 which is a 32 pin device, but, of course, is 1024k in size. Are EPROMs and EEPROMs addressed in the same way (in read mode)? If this works it would allow me to boot the computer, physically remove the EPROM, install the EEPROM and re-flash the bios. BTW - the reason I was re-flashing in the first place was because the board would only address the first 128Mb of a 256Mb RAM stick, even though the documentation I got with the board said it should recognize the full 256Mb.
