Asrock Phantom Gaming 9 extra bios
Just thought I would share this, maybe it is part of the bios? but its not always present, I discovered but cannot always reproduce that by pressing main menu favourites and trying many different combinations sometimes brings up another menu that I normally have never seen before. It is not the advanced Menu but another version of it perhaps other asrock phantom gaming 9 users could comment and perhaps show how this Menu with in-depth settings is reproduced.
I cannot always get back to this bios setting but its quiet in-depth
