When I fubared my K7S5A, there was a way to recovering the BIOS and reflashing it. This probably won't help, but I was able to recover using these directions (I found this on Google):
"If you are a little lucky, the "bootblock" code in the BIOS still works. This will allow you to flash your BIOS even though you computer seems dead. Format a blank floppy (on another computer, of course), and put the .rom file on it, and nothing else. Now rename the .rom file to this name: "amiboot.rom". Put the disk in the dead machine and turn it on. Wait for a couple of minutes (now would be a good time for a little prayer) and listen for four beeps. If you hear them, the bios on the floppy has been flashed onto your BIOS chip. Turn the computer off and on again, and it should work again."
