From Louis Ohland@21:1/5 to All on Fri Nov 12 13:41:46 2021
SYMPTOM:
SYSTEM HANGS MAY BE EXPERIENCED ON 8590 AND 8595 SYSTEMS
WITH A 50 MHZ PROCESSOR AND AN EARLY VERSION SYSTEM 36/38
EMULATION ADAPTER INSTALLED. THE HANG CONDITION WILL ONLY
OCCUR DURING POST (POWER-ON SYSTEM TEST) OR SET CONFIGURATION.
IF THE HANG CONDITION OCCURS AT ANY OTHER TIME WHILE RUNNING
THE SYSTEM 36/38 WORK STATION EMULATION PROGRAM ON THE ABOVE
REFERENCED SYSTEMS, CONFIRM THAT PTF #IM00479 (PROGRAMMING
TEMPORARY FIX) IS INSTALLED.
PROBLEM ISOLATION AIDS:
THE EARLY SYSTEM 36/38 EMULATION ADAPTER MAY BE IDENTIFIED BY A
FRU LABEL ON THE SYSTEM 36/38 EMULATION ADAPTER OF EITHER:
FRU P/N69X6282, FRU P/N69X6283 OR FRU P/N69X6292.
REMOVE THE SYSTEM 36/38 EMULATION ADAPTER TO MAKE SURE THE
PS/2 SYSTEM IS OPERATING CORRECTLY WITHOUT THE ADAPTER.
(ALSO REMOVE OTHER ADAPTERS.)
FIX:
THE EARLY VERSION SYSTEM 36/38 (5250 EMULATION) WORK STATION
EMULATION ADAPTER SHOULD BE REPLACED BY THE CURRENT FRU,
P/N69X6294.
