Does anybody know how, electrically, the flash is erased and reprogrammed? None of my books with BIOS stuff in them mention this. Is it a MEMW or an IOW line? Either way, if you remove the BIOS and place two of them on an appropriate ISA card with a switch on their enable pins, it should be fine (just be careful of the switch position before doing any flashing, of course).
Take a look at www.amd.com They sell flash-memories (and of course, CPUs :) There you can get a PDF-File for their Flash-chips.
