Pet peeve... BIOS and UEFI are not the same thing. UEFI is replacing the BIOS.mkenyon said:They're super cheap used here in the states. Want me to ship you one?
Check in your BIOS. Probably put it on a thumbdrive, go into BIOS and select the update option.
Usually, you put the ROM at the root of a FAT(32) formatted flash drive. Run the ASUS update utility in the UEFI, and it'll ask you where the ROM is.
After flashing, it's recommended to clear the CMOS and redo your settings.
