IMPORTANT: This manual is intended to test the IBM Machine Types 2193, 2194, 2196, 2197, 6344 and 6345 only. Testing
devices which are not included with the original product package, including other IBM products, prototype cards, or
modifying hardware settings may give false errors and invalid system responses. The diagnostics not specifically
made for this model may also report incorrect errors and information.
The diagnostics program comes on a CD (compact disk) along with this book. This version of PC-Doctor diagnostics program,
developed by Watergate for IBM, is the primary method of testing the computer. You can use it to test the IBM components
of the system and some external devices. The amount of time required to test components depends on the number of

longer the testing will take.
