i cant access the bios on 2 (god damn 2 of these peaces of junk) brand new ga-990fxa-ud3 (rev 4.0) its just going to the command prompt screen and when i hit the keys the screen just gos blank. i have brand new r9 290's gpu's, (kingston 4x4gb ram, 2x wd sata 500gb harddrive, 2x amd sempron 145 cpu, 2x ocz gold 80 plus 1000w psu all brand new) the r9 290's wouldn't even register a signal on the screen so i got an old 8800gts card to work on it. all i can do is hit command and gos to black screen. tried skipping on and installing Ubuntu from flash drive and its coming back with "unable to find a medium containing a live system" i need to get into the bios.

i brought the mother boards round to a pc repair technician and got him to update the bios to from f1 to f2 after i couldn't get the r9 290's
to register, the moron must of screwed up the bios update or something because when i got em home the r9 290's still wouldn't register. so i went and got a secondhand 8800gts for 25 bucks to do what the tech was ment to do and i cant access the bios...
i tried removing the battery, jumping the cmos pins but only to the same no access to bios. the board has duel bios and supposedly when the main bios becomes damaged the back up bios restores the main bios to factory setting.

is there some thing i have to do to make the back up bios restore the main bios or should it happen automatically?
