I am having trouble updating P4C800 BIOS. I have tried both new BIOS Versions without any luck. At the ctrl-F2 prompt I have tried both versions and get the message of : THIS BIOS DOES NOT MATCH CURRENT VERSION OF P4C800. I know that I have the correct BIOS because I got it directly from the ASUS website. I am not new to computers either. I have my own business. The current one that came installed is BIOS Version 1003. This BIOS is showing 2 processors at boot up. Strange because as you know, this M/B only uses 1 processor. The processor is a P4 2.4 800 MHZ. I am also having trouble getting it to recognize a 160gig Western Digital H.D.. I have the PCI Card installed that came with the Hard Drive but it is giving me hell trying to configure it even using the Maxtor install disk.:angry2: If anyone can help me please post as soon as you read this thread.
