Your board will have 2 BIOS chips. 1 "live" and 1 "backup". Why are you trying to flash the backup bios?

If you have updated to a stable Bios it is ok to flash the backup as well so there is no conflict in case the backup needs to recover the main

After restting the bios back to default settings have you tried ALT+F12 at post? Use a (PS2 Keyboard).

Hi

Fatman is correct but I will just re-iterate what he said. Make sure that you have a stable version on the Main BIOS chip before proceeding.

If you have a PS2 keyboarrd connect that instead of the USB version as it is more reliable.

From a cold start with the power to the machine switched off press the power button and then enter the BIOS by pressing Del.
 Then when you get to the main screen press F9.
 
This will bring up an extra screen which will display more information about the two BIOS versions. Assuming they are different exit the BIOS and shutdown.

Again press the power button and this time press Alt + F12 where you would normally use the Del key to enter the BIOS. You will find that then your monitor will turn black and you will see:

Press [Enter] to start copying main BIOS to backup BIOS...

When you press Enter more text will appear saying:

Writing BIOS image.... xxxKb OK

Once completed more text will show:

BIOS successfully recovered! Power off or reset system!

Do as it says. Both Main and Backup BIOS chips now store the same BIOS version. You can now reboot as normal.


When you copy the first BIOS image to the second BIOS it also copies the current configuration
 so if you use RAID or something, set it before the copy.  It also copies over any saved profiles too.
