Most motherboards have a jumper that you can short for a few seconds and it will get you back to factory defaults. However, when you flash a bios and it is wiped, it is gone for good unless you have some kind of motherboard with a backup bios eprom. Why they would go to the expense of having 2 flash eproms is beyond me because that kind of error rarely happens. Replacing a bios chip is very cheap unless you are getting it from Unicore, but I think putting a duplicate on each board is too costly.
