Diagnostic Aids 81
Diagnostic Diskette
WARNING: This manual is intended to test the IBM
Personal Computer Type 2274 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.
The diagnostics program comes on a diskette 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 components
installed and selected. The more devices you have
attached to your system and selected in PC-Doctor,
the longer the testing will take.
Using the Diagnostic Diskette
1. Power-off the system unit.
2. Insert diagnostic diskette in drive A.
3. Power-on the system unit.
NOTE: Do not press F1 during POST. If any POST
errors appear after POST, make a note of the

driver loads successfully. For drivers that do not
load successfully, verify that the device driver is
associated with it and is installed properly.
5. Diagnostics program (PC-Doctor) will load, then
