first, I want to say THANK YOU for this wonderful BIOS hack. It's really great to have all these menus unlocked! For those trying it for the first time: it Beeps a LOT flashing in DOS, mine did for about 5 minutes. Let it run for a while and don't turn it off! Now, I did this mod because my GPU fan is not responding on my M17X R4 except for when I use HWiNFO64. So I know the mobo works, but I don't understand the unlocked thermal settings. As far as I can tell, these are only for the CPU. Is there a tutorial on this section I could read? Has anyone managed to adjust the GPU fan in these settings? Thanks!
