IBM PS/2 - Adapter Compatibility (MicroChannel and Others)
Applicable to: World-Wide
Symptom:
Servicers may experience situations where adapters will work correctly in one or more personal computer system model/type, but the same adapter fails to function correctly in a different system type or model. This can occur in MicroChannel, PCI, ISA, EISA, PCMCIA and other bus architectures.The failures experienced may be a configuration error, a system board error, or an adapter error. The diagnostics for the adapter in question may run error free, but the system unit appears to fail when running the application software.
Important:
The servicer should not assume a system hardware failure on the host system if the other adapters work correctly and the system unit diagnostics run error free and other applications/software functions correctly with the suspect adapter removed.
Problem Isolation Aids:
This situation may occur when an adapter is moved from a slower PS/2 system unit (usually along with the software) to a faster PS/2 unit (the converse may also be true), or during an initial installation. The causes may be one or more of the following:-
a. The adapter in question may not meet the appropriate interface specifications. The possible discrepancy is made apparent when the adapter is running on a faster system. On the slower system the situation may not manifest itself.
b. The adapter in question uses software which uses processor speed dependent code. Operation in a faster system unit causes failures due to the speed dependent code.
c. Some adapters are not supported on all systems in the product line.
Fix:
Known problems may occur with specific models or EC levels of systems and/or particular adapters or types of adapters. Prior to replacing any FRU's, Retain/Notes should be searched for model or adapter specific information. In the absence of specific direction for the product set in question, and the adapter is either an IBM adapter, or an IBM supported OEM (other equipment manufacturer) adapter, the appropriate level 2 support organisation should be contacted for assistance. If the adapter in question is not an IBM supported OEM adapter, the customer should be referred back to their OEM point of sale to determine if the adapter is supported (tested and works) on the system type in which the failures are being experienced.
