    TITLE:  WinNT 4.0 and Bootable CD on Premium HS

    ISSUE

       When installing Windows NT, version 4.0, from a bootable Windows
       NT CD on a Premium HS system, Windows NT is unable to detect any
       hard drives connected to the I2O MegaRAID.

       This issue affects only the bootable CD install for the Premium
       HS systems.

    BACKGROUND

       N/A

    ACTION

       To resolve the issue, perform the steps below:

       1. Make the sure the Windows NT installation CD-ROM is
          inserted in the CD-ROM drive.

       2. When the Windows NT CD starts to boot, the following
          message will appear on the screen:

             "Setup is inspecting your computers hardware
              configuration". Press [F6] immediately."

       3. Within a few seconds, another message will come up
          on the screen prompting you to specify additional
          adapters in the system. Select [S] and press [ENTER]
          on the "OTHER" option in the selection screen.

       4. Insert the MegaRAID Windows NT driver disk and press
          the [ENTER] key.

       5. "MegaRAID NT SCSI Driver" will be displayed
          highlighted in the middle of the screen. Press
          to load the driver. Press  again to continue
          the operation as usual.

       By loading Windows NT this way, we have told Windows NT that the
       MegaRAID controller is the primary controller. Windows NT will
       now continue to install as usual.
