Im not sure what with that dual bios feature, because you would need 2nd bios chip for that... And ye it seems like Rampage Extreme have it, but Formula does not.... Thing is, more and more im looking in this 0002 bios, more im wondering if Asus screwed up and sended you wrong bios again and this is kind sad news, but i dont want to spread negative vibes and lets hope for the best! This 0002 bios is more smiliar to existing 1202 bios for Rampage Extreme, then to bios for Rampage Formula...
