    MANHATTAN P/V WITH NETWORTH PCI BRIDGE UTP4PCI NIC

    PROBLEM

    The Networth UTP4PCI PCI 4 channel UTP network interface card does not work
    in P5090.
    If SERVER.EXE (Netware 3.12) is loaded, and NCRSDMS3 disk drivers are loaded,
    followed by the UTP4PCI.LAN drivers (as well as ETHERTSM, MSM, etc.),
    the UTP4PCI driver continually reports LOST INTERRUPT DETECTED, and
    MONITOR.NLM reports that the LAN card is only sending packets, not receiving
    any packets at all.  The server can not be seen on the network by any other
    server or workstation."

    CAUSE

    This is a PCI bridge device, and AST current Manhattan P/V systems DO NOT
    support PCI to PCI bridging.  However, NetWorth provides the software,
    PPBINIT.EXE, to implement this bridging.

    SOLUTION

    This is only a workaround to provide the temporary solution to the PCI
    bridging issue.  Please follow the procedure closely.

    1) Always use the latest firmware and software on the Manhattan systems.
    In this case the BIOS is 1.09 (part number 905547-038) and the EISA
    Configuration Utility is 1.06 (part number 911371-037).

    Files 05547038.EXE and 11371037.EXE are available from AST's BBS
    AST's BBS (817) 230-6850, in the "Systems" file area.  The above files will
    also be posted on:

    For additional information on the BIOS and EISACU, see Software
    Bulletins 0178 and 0211 in AST's SBS library.

    2) Make sure that UTP4PCI board is installed on the PCI slot, next to the
    EISA slot, and shares IRQ 15 with the first embedded NCR SCSI controller.

    3)  Run the software provided by NetWorth -" PPBINIT -I15 5" (15 is the
    IRQ and 5 is the PPB Address) to initialize the 4 channel PCI network
    interface card.

    4) Run the software provided by NetWorth - "DIAG4PCI.EXE" to diagnose
    the board.
