Title: UEFI BIOS and GA - Z68X-UD4-B3
Post by: vampyren on November 26, 2012, 12:30:06 pm

Hi guys,

i just wanted to highlight this for other whom might end up in my situation and also ask some question myself.
Yesterday i bought Windows 8 and i though i check if there are any updates to my Bios and i say several updates actually.
i was at F7 and there were F8,F9, F10 and a new U1c which supported UEFI BIOS. I was curious to test this so i started to use the "atBIOS" windows tools to upgrade my bios. Up to F10 it went fine but no matter what i did (from server or local file) i could not flash U1C. I got the message i'm using the wrong version or something.
I even tried the Qflash and put the file on USB stick with an error message that the file is wrong.

So after lot of testing i decided to use a bootable USB stick. Once i had a working bootable USB stick i finally managed to flash the U1C through DOS. Using this command and file--> FLASHEFI Z68XUD4.U1C

So my question is why couldnt i flash using QFlash ? or even the windows tools?
I'm sure i use the correct file and as mentioned it went fine using bootable usb stick. I'm not running windows 8 on top so its working fine and all but i'm just puzzled about the whole case. Next time i'm not sure if it will work using windows tool for one...

Hope someone can clarify this....

I think it is the firmware of the bios itself that doesn't see the new bios update. I think the site it will tell you that to:

Please update @BIOS to ver.2.33 and be sure to reflash this BIOS through @BIOS ver2.33.

That is what it is telling me on my x79-UD3 board. I had the same problem trying to go to F16.

Beta BIOS
UEFI BIOS
(When updating from legacy to UEFI, use only the utility attached to your BIOS file)

Simple answer (I believe) is non UEFI bios is coded by Award and UEFI is coded by AMI

Each has its own flash utlity.

So if you want to go back from UEFI you need to manually flash back with an Award utility
If you want to go from the earlier standard Award bios versions to UEFI then an AMI utility
is required.
