Extra BIOS settings for Gigabyte boards

[10DD]

I remember hearing that its possible to extend the normal BIOS settings for Gigabyte motherboards.
It allows a few extra settings etc.
Has anyone else heard of this? If so how do I go about it.
Thanking you!

CTRL + F1 unlocks extra settings. Do it on the main page when you first enter the bios
