TITLE: DATE: 1995
AUTHOR: Elaine Davis TD #:
DTN: 276-9836
ENET: STOWOA::EDAVIS CROSS REFERENCE #'s:
DEPARTMENT: MCS PSMG (PRISM/TIME/CLD#'s)
INTENDED AUDIENCE: ALL PRIORITY LEVEL: 1
(U.S./EUROPE/GIA) (1=TIME CRITICAL,
2=NON-TIME CRITICAL)
=====================================================================
PROBLEM:
-------
Product: PCI to FDDI Adapter Card (DEFPA)
The DEFPA-AA/DA/UA may exhibit a problem in PC's with the Intel
Triton Host-to-bridge chip.
The INTEL Triton Host Bridge chip has a problem in its arbitor
logic
that exposes a problem in the DEFPA-AA/DA/UA. DEFPAs installed in
platforms with the Triton chip may cause the DEFPA and PC to hang
or
experience a degradation of performance.
NOTE: THIS PROBLEM OCCURS IN INTEL TRITON BASED PLATFORMS ONLY!!
VERIFICATION THAT PLATFORM IS TRITON BASED:
------------------------------------------
Determination that the PC uses the Triton chip is made as
follows:
There is an executable program, PCIVIEW.EXE, that scans the PCI
bus
and list all of the devices attached to the bus. This file can be
copied from:
NPSS::PUBLIC$DSK:[INTERCHANGE]PCIVIEW.EXE
Load and execute this file from DOS.
Look for the device type that specifies the "HOST BRIDGE"
The print out format is as follows:
Device Type = Host Bridge
Classcode=60000, BUS = 0,Device = 0,BUS Master = Enabled,Slot =
Enabled
Vendor ID = 8086, Device ID = 122D, Revision ID = 1, Interrupt = 0
IOport = 0, Memory = 0
If HOST BRIDGE Vendor ID is 8086 and the Device ID is 122D, you
have
the INTEL Triton Bridge chip in that PC.

DEFPA-AA A01, B01 54-22499-02 C01,D01
DEFPA-DA A01, B01 54-22499-01 C01,D01
DEFPA-UA A01, B01 54-22499-03 C01,D01
Note: the DEFPA-MA (54-24275-01) does not have this problem.
SOLUTION:
---------
A new module revision (5422499-01/02/03 Rev E01) will be
available
from manufacturing by May 17, 1996.
WHAT TO DO WHEN A CUSTOMER HAS THE TRITON PROBLEM:
--------------------------------------------------
1. Verify that the customer has a Triton based Platform.
2. Order FRU revision per the table below.
Note: There is a very limited number of the new revison modules
available until mid May 1996. Please contact the NPS Hotline
for assiatance until the new revison is available.
Phone 508-486-6789, DTN 226-6789
EMAIL NPSS::HELPDESK
FAX 508-486-5165, DTN 266-5165
Minimum FRU revision for DEFPA's in Triton based platforms must
be as
follows.
Option REV Board Part Number REV
-------------------------------------------------
DEFPA-AA C01 54-22499-02 E01
DEFPA-DA C01 54-22499-01 E01
DEFPA-UA C01 54-22499-03 E01
POSSIBLE "SHORT TERM" WORKAROUNDS (UNTIL MID-MAY 1996):
--------------------------------------------------------
1. If the customer has EISA slots available in his platform, a
DEFEA
FDDI/EISA adapter can be used.
2. If the customer can use UTP media, the DEFPA-MA (DAS UTP) can
be used.
