Diagnostic Diskette
WARNING: 
This manual is intended to test the IBM 
Personal Computer Type 6832 and 6833 
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.
