The table below lists the tests you can run on the system’s
internal devices and on any optional devices you have installed.
You may not see all of the tests listed when you run System
diagnostics. Some tests appear only if you have installed certain
types of equipment. The program displays the title of each check
on the screen.
Tests that check the operation of parallel or serial ports require
you to use a special connector in order to test the device.
Contact your dealer to obtain the connector listed in the table
below before beginning the tests.
For a complete list of the error codes and messages these tests
may display, see the table at the end of this appendix.
