Only use Beta BIOS's if you know the individual that made them, and know they are safe. Either that or only use BIOS versions from Asus. You could really get nailed bad, and loose ALL of your hardware. Downloading a BIOS from a complete stranger especially overseas could get you something like Chernobyl. Anybody remember that? It was a Virus that killed hardware. It would do nasty things like reset your voltages for you...to a setting you would not like after it burned up your hardware.
