        Manhattan P5090 OS/2 Warp Corrective Services XR_W010 Install Hangs
    			       with Error 3175

    PROBLEM

    While trying to install the Corrective Service Fix XR_W010 on the Manhattan
    P 5090, with OS/2 3.0 (Warp) Connect installed, the system hangs with system
    error 3175.  The system is using a DPT3224 SCSI adapter and five 4 GB hard
    drives in a RAID5 configuration  This happens during operation of the first
    service diskette.

    CAUSE

    The Corrective Services package does not contain driver for the DPT HBA.

    SOLUTION

    1. Create an OS/2 3.0 driver diskette by using the DPT Storage Manager.

    2. Copy the file "DPT20XX.ADD" from this diskette  to "CSFBOOT2"
       diskette of the service pack.

    3. Edit the CONFIG.SYS file on CSFBOOT2 diskette using a text editor such
       as DOS editor.

    4. Add the following line at the beginning of CONFIG.SYS

    	   'basedev=dpt20xx.add'

    5. Start the installation using the modified CSFBOOT2 diskette.  The system
       will recognize the DPT SCSI adapter and all the hard drives connected to it.

    SYSTEMS AFFECTED

    Manhattan P&V with DPT 3224 SCSI HBA.
