I tried the beta F8b bios with the the AHCI rom and before Windows started loading, the BIOS said that it was updating the backup BIOS with the new one I had just flashed. Unfortunately, the computer rebooted before Windows loaded and got a BSOD the second time around. I reflashed the main BIOS to F7 final to be safe, but since there was no text saying the backup BIOS was also flashed, I assume the backup BIOS is the beta F8b BIOS that did not work for me.

My question is this: is there a way to manually flash the backup BIOS to the F7 final BIOS so that if something happens, the computer will not try to load a backup BIOS that does not work?
