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. 


SYSTEMS AFFECTED
AST PART NUMBER AND DESCRIPTION
 
501502-XXX MANHATTAN P - ALL MODELS
501500-XXX MANHATTAN V - ALL MODELS


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.
