Just discovered this one on my own Gigabtye motherboard. During my travels I was reading and Gigabtye HIDE some bios options you the user can unlock. In my case this trick opened a few extra BIOS options for me most prominently the PCI Latency Timer. To do it go into your BIOS. Hold CTRL and Press F1. Now if there was anything extra it will have unlocked! you may have to check your bios options then do the trick and then compare as sometimes we miss things especially if we aint been in there in a while!
