Hi, i'm trying to upgrade this mobo to a PIII 600E. I went to their site and flashed my mobo and looked at the jumpers and all but it still won't boot with a PIII 600E (i have two of them). It is suppose to support up to 800MHz too. Celerons and PIIs with a 66MHz FSB work fine, but the instructions or instructions on the web don't say how i would change it to 100MHz FSB, it says that it is just suppose to be able to detect it accordingly. HELP! Thanks!
