Dead BIOS - Acer S82MA Motherboard/Winbond W49V002FAP Chip
Posted: Sat Dec 02, 2006 2:50 pm
OK, I was informed by a 'reliable' source that the S82MA was the same as an AOpen MX4B, so I flashed the BIOS of the MX4B onto the S82MA. As you may have already guessed, this was not a good idea. Boot-block mode is not automatically started, so the checksum must be correct. I have no video, no hard drive activity and only the DVD drive's light flickers; and my computer lacks an internal speaker. Any ideas which pins I need to short on the Winbond W49V002FAP chip to force an error, and please explain how I would go about 'shorting' them?
I don't think it's an LPC chip, but I am new at this sort of thing (hence my lack of knowledge on how to short pins exactly). I have the datasheet, but frankly, I don't understand it. Anyone willing to help may need the datasheet, so here it is:

EDIT: I apologise, but I forgot to add: when I connect a PS/2 keyboard, none of the status lights flash or will turn on. The floppy light will not turn on either, but this may be because the BIOS isn't set up to boot from floppy in its normal non-BootBlock mode, could it not?
Thanks in advance.
