completed without errors, the system will then proceed
with the loading of DOS or other operating system from
diskette drive A or a hard disk drive or CD-ROM drive,

If any errors are detected by POST, there will be an error
message accompanied with an error code shown on
display screen and a beep. See “Index of Symptoms,

Diagnostics Tools
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 components installed and selected. The more
devices you have attached to your system and selected in
PC-Doctor, the longer the testing will take.

3. When screen prompts to install original software, type N

press Enter to start the diagnostics program. Follow the
instructions on the screen to operate the diagnostics
program.
