    Default How can i downgrade from uefi bios u1h back to award bios f12

    I can't seem to downgrade my bios from U1h back to F12. I used EFI2ward utility but keep getting errors. Could it be that after i flashed to UEFI bios , i did another flash using Q-flash so as to make the dual bios the same version and now i cannot go back. Please someone let me know if i can still flash back to Award Bios.

    This UEFI bios works great on Windows but it screwed my Sleep / Wake functions on my Hackintosh. It doesn't power down after i put it to sleep and only way to wake it up is to do a reset.
    I cannot do any overclocking on my Hackintosh.

    I want to go back to F12 bios for my Mobo to be able to overclock and also fix the Sleep/Wake function with DSDT.

    Is it still possible to go back from U1h to F12 . Please help.. thank you.

    Make a bootable Fat32 USB drive . The link to make one is from here >
    http://www.computerforums.org/forums...le-212383.html

    Download Efi2awd utility and Gigabyte Hybrid EFI bios from Gigabyte website .

    Extract Efi2awd utility and extract the Bios file onto 3 files.

    Now put the Efi2awd executable file and the bios file onto this bootable USB flash drive.

    Reboot your computer and boot from this USB drive.

    Windows 98 will flash and arrive a C command prompt.

    At the command prompt, type dir/w to see the directories

    Type the : "Executable file name"space "Bios file Name" without the quote and hit enter.

    It takes less than two minutes to flash and you are all done.

    Now you can do a Q-Flash for Gigabyte motherboard to make your Dual Bios the same version.

    Enjoy.
