I upgraded my GA-Z68X-UD3H-B3 from its BIOS (ver. F12) to UEFI (ver. UL1.) Can I downgrade back to BIOS just by flashing it again? I've read that I should use efi2awd.exe to flash it, and that I should use the ordinary BIOS definition file from the mobo's download page. Is this true? Is there an approved source for efi2awd.exe?
Thanks.
