    How does this affect the operation of the system in Win98SE? We do this in Win2k with one CPU so that the IRQ's can be manually assigned but I would appreciate more info about doing this in Win98SE. We are using CUSL2-C systems with PIII 1GHz CPU's, 512MB RAM and RME audio cards. Matrox G-450 for graphics.

    3. reboot and ignore/cancel all driver install prompts.
    4. Control panel/Add New Hardware/next/next/No/Next/System Devices/
    Next/highlight standard system devices in the left pane and
    scroll to Plg in Play BIOS (fail safe) in the right hand pane
    and ok it apply it and let the system re-detect your hardware

    5. Instal IDE driver : Conrol panel/Add New Hardware/Next/Next/No/
