I reported a month ago that nVidia had released a utility that lets you overclock your nForce mainboard from within Windows. It then listed the Abit NF7-S mainboard as one of the few that should work with this utility.
Today Abit has released a updated BIOS that adds compability for this. The BIOS is however only for rev 2.0 users so even if my rev1.2 board had not failed I'd been left out in the dark. Just like all other rev 1.x users have been.
