How to flash the gigabyte 6 series mobo to uefi bios?

Yes.
First, flash this BIOS with changed ID, by me, for your board (7A89UG09)
Then re-flash the original BIOS from the board with the B3 note.
P.S. you need to upload the original a second time, because elsewhere after uploading you may still see the board ID P67-UD3 (without B3)

Thanks mate! But Qflash doesnt like checksum of your file (06F6). I fixed it by reinserting Logo.bmp with cbrom155. Now checksum is D800, but Qflash still dont like the file. What can I do?

Flash it with @ Bios

Thank you very much! Looks like almost everything is ok, now I have Ivy Bridge Xeon onboard.

But as I saw at first loading, second (backup) bios was overwritten by new one so this dual-bios protection is not very solid :slight_smile:

Have issue with usb keyboard - doesnt work until windows load. Tried to toggle USB Legacy and Fast Boot on and off, but no success.

And it froze couple of times on windows desktop loading - keep looking on it.

You can try UEFI BIOS for P67A-UD3-B3. The AWARD → AMI update tool overwrites both BIOSes, to prevent this, flash it via the flashrom tool.

Command: flashrom -p internal -c “name of your BIOS chip, like MX25L3206E” -w (BIOS file)
