Hi there,

could you post back with details of your motherboard?

Yes, that's what we needed.

Right, first things first, welcome to the forum!
When a BIOS Flash goes bad the first thing to do is try and re-set CMOS. If your not sure how to do this check out this FAQ: http://forum.giga-byte.co.uk/index.php/topic,2286.0.html

If you follow this procedure there is a good chance that your BIOS will recover.

Hello! Му problem is solved. Clear CMOS was unsuccessfully for me. On Russian Gigabyte forum i find а method to reanimate BIOS boot loader: during POST necessary to short 1 & 8 pin on main BIOS chip. This should be done for half a second after 1-3 second after start. Sometimes it does not work the first time and need a few attempts. I turned on the third attempt. After boot loader start, it recovery main BIOS from backup BIOS chip and my computer normally boot!. Thanks for all!

Pleased this worked for you and great to know you're back up an running.

I have been aware of this "Fix" for a while but am not sure how reliable or safe the procedure is and I haven't tried it for myself.

I had no other option except this or programmer in service center but it expensive and time consuming. Regret for such a fine technology as DualBIOS not working as it should be. Requires unconventional and dangerous action to make it work...

Yes I know very frustrating.

When you tried to update BIOS the first time in QFlash did you disable the "Keep DMI Data"  before flashing the BIOS?
From this:


Change to this:


Not sure if this may have caused the problem as I am waiting for a response to a technical question I have asked Gigabyte.

Yes I couldn't understand that! The whole purpose of the DulaBIOS was that if one became corrupted the the backup was supposed to automatically replace it on next boot.That was the whole point of the backup BIOS not being user programmable.  ???

could it mean those 11 beeps that the board could not fix the main bios by the backup?

I have raised this question with the forum moderator but, I know he is a bit pressed for time at the moment so might not be able to respond for a couple of days. As soon as I get an answer I'll let you know.
