            Manhattan P Netware SFTIII 3.11 with Thomas Conrad TC3047ST

    PROBLEM

    The Thomas Conrad TC3047ST MSL netware card is unstable with SFTIII
    version 3.11, in the Manhattan P system.  The system will also fail during the
    memory test.

    CAUSE

    System BIOS prior to revision 1.12 set the PCI EISA Bridge (PCEB) PCI control
    register 40H bit # 2 to 1.  This bit must be set to 0.

    SOLUTION

    AST Manhattan P and V BIOS 1.12 (part number 905547310) sets the control
    register bit to 0 to fix the problem.  To resolve the problem, flash the
    system with BIOS revision 1.12 or higher.  To obtain this BIOS do one of the
    following:

    1. Call AST Technical Support at (800) 727-1278.

    or

    2. Download file 05547310.EXE from AST's BBS by dialing (817) 230-
    6850.  AST's BBS supports modem speeds up to 28.8k bps.
