IBM PS/2 - WAC Adapter Overlays System Diagnostics

Applicable to: World-Wide

Symptom:
When attempting to run system diagnostics on the 9557 (after booting the system partition and doing a CONTROL/ A), the only diagnostic that is available is the WAC adapter (Wide Area Connector Adapter) diagnostic. All other system diagnostics have "disappeared."

Note:
The problem may be seen on any PS/2 IML system.

Problem Isolation Aid:
1. A WAC Adapter (FRU P/N33G8453) is installed in the system.
2. When running diagnostics from the System Partition, only the WAC Adapter diagnostic is available. No other hardware diagnostics are visible.
3. The system diagnostics may still be run by booting the back-up Reference Diskette (set) from the diskette drive.
Refer to the label on the diskette and determine if the WAC Adapter Option Diskette is version 2.1.

Version 2.1 of the WAC Adapter Option diskette erroneously overwrites critical diagnostic control program files on the system partition of the PS/2 system.
Version 2.1 of the WAC Adapter Option diskette was only available from the IBM PC Company Bulletin Board from 3/31/94 through 6/26/94 and was never shipped with the option.

Fix:
A current WAC Adapter Option Diskette (version 2.20), which corrects this problem, is available from the IBM PC Company All copies of the down-level option diskette (version 2.1, IBMWAC21.DSK) should be destroyed.
