IBM PC730/PC750 - System hang with 256Kb L2 cache
Applicable to: World-Wide
Symptom :
IBM PC 700 Series 6875, 6885, 6876, or 6886 systems with 256Kb Level 2 cache installed may exhibit intermittent system hangs in OS/2 2.x, OS/2 WARP 3.x or in a Windows operating system environment.
Problem Isolation Aids :
Disable the 256Kb Level 2 Cache via the Setup Utility and retest the system. If the system does not exhibit further system hangs, continue with the following step:
A) Locate the level 2 cache modules on the system board. If either of the modules are ALLIANCE brand cache modules with a date code of 9539, 9540 or 9542 this tip applies.
If the system hangs continue after Disabling the 256Kb level 2 cache, continue normal problem determination.
Advanced diagnostics run without errors.
Fix :
If the system does not exhibit the failure symptom with the cache Disabled, replace the cache with FRU P/N 06H6052.
