Check the pc or drive controller manufacturer's web site. You didn't mention
the drive controller (possibly SCSI, or ultra DMA, or ATA100, or raid), but
you may need to boot the Windows 2000 setup disks or CD-Rom and *F6* very
early and very important (at setup is inspecting your system) in the setup
to prevent drive controller detection, and select S to specify additional
drivers. Then later you'll be prompted to insert the manufacturer supplied
Windows 2000 driver for your drive's controller in drive "A"
If you wait and then S to specify additional drivers, then it may be too
late as Windows 2000 Setup at this point may have already assigned the
resources your drive's controller is wanting to use.
