I tried to update my Extreme6/ac BIOS from 2.10 to 2.20 from Windows (as administrator) and from within the UEFI. Both failed. Starting in Windows, on reboot the screen froze on the ASRock BIOS screen and an A2 error code in Dr Debug. Switched to BIOS B and restored BIOS A successfully to 1.40.
I tried updating from within the UEFI - the file section showed the BIOS 2.20 file name but then quickly changed the displayed file name to "config.sys" and froze. I could do nothing but reboot. I could see no config.sys on my flash drive and even tried reformatting it but the UEFI still quickly switched to showing config.sys and froze. In no case could I actually start a BIOS update within the UEFI because I could not actually select the BIOS name to start the update.
Switching to BIOS B, I tried again to update from within Windows (thinking it would update BIOS A and knowing that BIOS B was protected). Now, both BIOS A and BIOS B freeze on the ASRock BIOS screen with an A2 code. I have tried unplugging the power, switching back and forth, and leaving it on the frozen ASRock screen for six hours.
I now see the A2 code means an IDE or SATA error (I don't have any IDE drives and I didn't change anything with my SATA drives or connections).
What to do to restore my BIOS?
