If you can manage to boot a proper "Crisis Floppy" you may be able to save your original motherboard. Search for that term on google. I *BRICKED* my Compaq notebook after hex editing the bios and flashing it. I was able to *UNBRICK* it with the Crisis Floppy. The idea is there is just enough of the BIOS at the front end (16K?) that knows how to flash itself from a floppy. If you clobber the rest of the BIOS it doesn't care.
