I have a new MSI mb (MSI NEO2 FIS2R) with 1gb matched pair of 467mhz Corsair, and 80gb WD hd. I have nothing overclocked. The bios accurately IDs the drive, but my XP installation CD cannot find the drive. Western Digital tools (which came with the drive) IDs the drive as well and can run Western Digital's diagnostics, but can't install their smartdrive application from the floppy because 'there are no Western Digital drives detected'. The bios version is dated (approximately) 6/24/3. I didn't find that issue addressed on subsequent bios updates on MSI's website. I've switched to a 40gb WD drive from another computer (that worked fine on the other computer) and got same result. I've switched IDE cables with others that I knew worked, and switched the HD connection from IDE 1 to IDE 2 on motherboard. I've set dip switches on the drive from neutral, to master (no slave) and left it off completely. I switched the RAM to the other slots and also tried each stick separately. The CD ROM and floppy are recognized and perform as expected. I've sifted through the bios settings and found nothing that helps...but then the bios recognizes the drives just fine. :P Thoughts?
