Diagnostic CD
IMPORTANT:
This manual is intended to test the IBM
6644/6645/6646 machine type 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.
NOTE:
Didgnostics will be included on the Recovery
CD 1.
This version of PC-Doctor diagnostics program,
developed by PC Doctor 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 components
installed and selected. The more devices you have
attached to your system and selected in PC-Doctor,
the longer the testing will take.
NOTE:
The diagnostics program for Type 6644/6645/
6646 are the same.
