Introduction
This booklet describes how to use the diagnostics program,
called DIAG, to test the condition of your computer’s main unit
and peripheral devices, The DIAG program provides tests to
check the following hardware:
System board
Memory
Hard disk drive
Diskette drive
Keyboard
Video adapter board and monitor
Printer and communications ports
After you start the diagnostics program, you can create a
database that records the location of faulty memory chips, if any
exist. This database displays a graphic representing your
computer’s memory board and identifies the faulty chips.
Once you select a test, you need to specify how long to run it.
You use the Run Time Parameters window to specify a certain
length of time to run the test, run it continuously until you
interrupt it, or specify a number of times to run the test.
