major bios problem fatal1ty fp-in9 sli

hi. hoping you can help. i was flashing my board to bios 14 (fatal1ty fp-in9 sli) and my pc crashed during the process. I had to reset my machine and when it booted i received an error saying:

bios rom checksum error
keyboard error or no keyboard present

detecting floppy drive a media
drive a error. system halt

Is my mobo ruined or can i retrieve it if i install a floppy drive and flash it from there?

thank you in advance

sounds like the bootblock is still intact
