Actually I physically checked the chip on the mobo last night when I got home, and it isn't the enhanced version. It's weird though because everything else indicated that I had the enhanced board, but the chip doesn't lie.
Without the enhanced board, I can only upgrade to the 2.6 w/400FSB which I've heard they make anymore, so that leaves the 2.4 or 2.5 which really wouldn't be that much of a difference, so I'm out of luck.
Or maybe I'm in luck...
