You may be able to call Biostar and have them send you a new BIOS chip for you to pop in.

Question:
What do I do if the system BIOS gets corrupted by my attempts to update it?
Answer:
All modern Biostar motherboards are equipped with the BootBlocker technology. This could be your last resort to salvaging a corrupt system BIOS.

1. Make a bootable floppy disk using Windows 95/98/ME.
2. Download the appropriate BIOS file and Award flashing utility from Biostar web site and copy them to the bootable floppy disk. If the Award flashing program isn't named "AWDFLASH.EXE", please rename it to "AWDFLASH.EXE". This is very important.
3. Insert the bootable floppy disk into the floppy drive. Power up the computer.
4. At this point you will not see any video display on the monitor, but the LED on the floppy drive should flash indicating activity.
5. Wait at least 3 minutes, then turn off the system and remove the floppy disk.
6. Power on again. If the BIOS was restored successfully, you will see the familiar POST screen.
7. If the BIOS was not restored, you'd need to return the board to your supplier for replacement.

If RebateMonger's suggestion doesn't work, there is one other thing you can try. It isn't exactly recommended, and it requires temporary access to another machine with the same motherboard.

The BIOS chip on your motherboard is socketed and can be removed. If you have access to another motherboard of the same type, you can boot it, then remove the BIOS chip from that motherboard and put your motherboard's BIOS chip in. You then reflash the BIOS on the running computer. This should restore the correct BIOS to your chip.

Again, not recommended unless other options are exhausted, be very gentle in extracting and inserting chips, ground yourself before touching circuit boards, etc.
