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.
