This is bugging me, My 990FXa-UD3 is running F6e bios, The Beta. The backup bios, however, is F3, this doesn't work with the FX-8120, so should anything happen to the Main bios: I will not be able to boot this system. Is it at all possible to flash the Backup Bios on Gigabyte boards? There doesn't appear to be a setting in the Bios itself to copy it over, nor does there appear to be any documentation for it on the Gigabyte UK site.
