IBM PS/2 - 9556, 9557 with 1184 diagnostic error and/or hang
Applicable to: World-Wide
Symptom:
On some PS/2 9556 and 9557 systems, an 1184 serial port diagnostic error may be experienced. This usually occurs only when the serial port (async) diagnostics are looped several times. During normal operation, this failure has a very low probability of occurring; but would probably result in system hang with no error code or message.
Problem Isolation Aid:
Loop the serial port (async) diagnostics for at least 10 minutes.
This tip applies only to the following models:
- 9556 mod DBA, DB6, and 2BX
- 9557 mod DBA, DBG, and DB6
Fix:
If the looped serial port diagnostics fail with an 1184 error, replace the system board. If the diagnostics run error free, continue normal problem determination.
