Use the following procedure as a guide for computer
problems.
Note: The diagnostic tests are intended to test only IBM
products. Non-IBM products, prototype cards, or
modified options can give false errors and invalid
system responses.
1. Obtain the failing symptoms in as much detail as
possible.
2. Verify the symptoms by attempting to re-create the
failure by running the diagnostic test or by repeating
the same operation.
Note: To run the diagnostics, refer to "How to Run
the Diagnostics" on page 212.
