MSI P35 board is a crappy board to start with. P35 to X48 to NV780 series, any of these boards with MSI on it is A PIECE OF SHlT! The BIOS supports P-M-S, you can't get rid of it until MSI get rid of its engineers. retail board that comes loaded with beta BIOS should be avoided at all cost. unfortunately, that's how MSI want to do it. I've never come across board/BIOS that has given me such shitload of headache, but MSI consistently did it in the past 12 months! a true champion! their graphics product is good, but their board definitely can't make it. they need to fire somebody in the designing/engineering team. change your board.
