STATUS: BBS:YES
(Reference TDR H053276 + H055684)
SYMPTOM:
This tip provides information concerning a potential data integrity
problem on PS/2 micro channel systems configured with the adapters
listed below.
Adapter Name Option# FRU P/N
--------------------- -------- -------
IBM LANStreamer MC 32 33G9030 59G9047
IBM LANStreamer MC 16 60G0511 60G0655
IBM EtherStreamer MC 32 60G1573 59G9081
In normal circumstances, the chances of experiencing data
corruption are extremely small. However, the risk of data
modification or loss can be eliminated in the noted hardware
configurations by making the following changes:
a. Increase arbitration priority
(a lower arbitration number corresponds to a higher priority)
b. Disable fairness
c. Disable loop-back
d. For 16-bit microchannel environments, set the receive buffer
size equal to the maximum frame size.
Items A and B are changed using "Change Configuration" (from
the "Set and View Configuration" menu) on the System Partition.
Items C and D are changed by editing the PROTOCOL.INI file.
(these are only required for NDIS)
Temporary work-around:
When the above configuration changes are made, the following
PS/2 system/model configurations are NOT exposed to data
modification:
- All PS/2 systems, including the 8600 models 195/295*, with
only 1 of the referenced EtherStreamer or LANStreamer
adapters installed.
Notes:
- On PS/2 models 8595-AMX or 9595-AMX or any PS/2 upgraded with the
Enhanced 486/50MHz Enhanced Processor Upgrade option must have
ECA001 installed on the PC.
- On PS/2 9585 turn off the LANStreamer or EtherStreamer adapter's
data streaming function using "Change Configuration"
Fix:
Corrected LANStreamer adapters are now available. There are new FRU
numbers associated with these new adapters. Any adapters with the old
FRU numbers needs to be replaced.
Adapter Name Old FRU# New FRU# ECA Nbr.
