    			 STORAGE MANAGER AND WINDOWS NT 3.5 SETUP DISK

    PROBLEM

    During installation of Microsoft Windows NT operating system, the operating
    system does not recognize the DPT PCI Disk Array driver disks that have been
    created by the DPT Storage Manager Utility.

    CAUSE

    The Windows NT installation program requires that the file OEMSETUP.INF be
    located in the root directory of the floppy diskette containing drivers to be
    used with Windows NT.  File OEMSETUP.INF provides information to the operating
    system, such as the name of the driver and the location of the drivers on the
    diskette.

    The Storage Manager program, which is used to configure the PCI Disk Array
    subsystem, creates the Windows NT driver disk with the OEMSETUP.INF file in a
    sub-directory of the floppy diskette. The Windows NT program does not
    recognize the diskette as a valid driver diskette for Windows NT.

    SOLUTION

    A corrected version of the Windows NT driver diskette is available on the AST
    electronic bulletin board system.  Use the diskette created by the files
    downloaded from the BBS, instead of the diskette created by the Storage
    Manager utility, when installing Windows NT.
