    Confusing WHQL BIOS setting on GIGABYTE mainboards


    I am installing Windows 8 and the Gigabyte mainboard gives three options regarding the OS

    Which one to choose??

    Obviously it is one of the Windows 8 options. Both will unlock a few new settings like the Compatibility Support Module (CSM) or (not visible on the screenshot) Secure Boot. But the new options are exactly the same if WHQL is chosen or not.

    The manual very helpful and I am being sarcastic here.

    So, which to chose and why and what do they do?

    From what the attachment show, I would say the Windows 8 setting would be for the Windows 8 Secure Boot only, or may be considered as Windows 8 UEFI only. In this mode, Windows 7 would not be allowed, Secure Boot Certified OSes, such as Windows 8 or Ubuntu 13.04 would. You can test by booting to a Windows 7 Install DVD in the UEFI configuration. It may allow the boot up to a point (possibly the 4 colors coming together) but should throw an error message or put you back into the bios setup if Windows 8 secure boot is active.

    Windows 8 WQHL is probably restricted to a UEFI boot but will allow Windows 7 or other Non-secure boot OSes in UEFI mode.

    The other is for other OSes and may be needed for Legacy (MBR) systems.

    The important thing to watch is the CSM. If it is disabled, you are in Windows 8 Secure Boot. If it is enabled, you will be able to boot Windows 7.

    Thanks. Will try and report results. Meanwhile I installed with CSM: OFF, Secure Boot: ON, still both Win 8 and Win 8 WHQL are available to do that. WHQL points to driver signing.

    This mystery has been resolved by Gigabyte support.

    The "Windows 8 WHQL" Setting is only for Systemintegrators to run a full Microsoft WHQL test.
