ok, I finally purchased a cusl2-c mb off e-bay. I set everything up and it wont post. It starts, runs the cd rom, floppy and hard drive but wont post. All jumpers have been checked and are correct. I see from asus website, celeron 633 is only supported from bios 1006 and above. I have no way of telling if this bios has ever been flashed or not. Apparantly the (c) designation boards do not support ppga processors which are the only other intel processors I have. My questions are(1) does this sound like it could be a bios problem? (2) will trying a ppga processor harm anything? (3) is there any way to find out the bios # or flash the bios without posting? thanks!
