    TITLE:  Man P/V, Intel Pro 100B, & NetWare 4.1

    ISSUE

       The Manhattan P & V servers may experience lockup problems under
       Novell Netware 4.1 when the Intel EtherExpress Pro 100B is
       installed in slot 2 (location J8) which shares an interrupt with
       the on-board NCR SCSI controller.

       This issue affects all Manhattan P and V systems.

    BACKGROUND

       N/A

    ACTION

       To resolve the problem, perform the following steps:

       1. Upgrade the BIOS to version 1.14 (AST part number

          from any of AST's On-Line! services as follows:

       For additional information on the Manhattan P and V BIOS, see
       Software Bulletin # 0178, on any of AST's On-Line! services.

       2. Ensure that Intel Netware drivers are version 1.48 or
          later. File 100bdisk.EXE is accessible at the
          following site:

                      http://support.intel.com

       3. Ensure that the latest Novell Netware patches are
          installed.  Check file "patlst.txt" for a complete
          list of patches for each Novell Operating System.
          These are accessible at the following site:

       CAUTION: In order for attached SCSI devices to work properly
       after updating Manhattan systems to BIOS version 1.14, obtain the
       new drivers from Symbios Logic for the 4.0 SDMS PCI SCSI chipset.

       FAILURE TO UPDATE THESE DRIVERS MAY RESULT IN CORRUPTION OR LOSS
       OF DATA.

       These drivers are available at the Symbios Logic website in the
       following location:

             ftp://www.symbios.com/pub/symchips/scsi/drivers/

       and Symbios Logic's BBS at (719) 533-7235.
