Chapter 1

This chapter describes how to start and use the diagnostics programs.

To start the diagnostics programs, follow these steps:

1. Turn off the computer and wait for a few seconds.

2. Place the diagnostics diskette in drive A, and secure the disk drive.

3. Turn on the computer.

The computer tests itself, and then automatically starts the diagnostics.

Whenever you turn on or reset the computer, the system performs some

built-in diagnostics called the power-on self test. This test checks the RAM

(random access memory), keyboard, system board, and peripherals before
the computer begins normal operation. For a complete description of the
power-on self test, refer to Appendix B.

If the self test encounters a problem, you see an error message. The error

messages are described in Appendix B.

If the self test finds a discrepancy between the equipment installed on the

computer and the equipment list maintained by the computer, an error

message displays. You can run the SYSTAT program (described in Chapter
7) to see the list of equipment installed and to check the current settings for

your configuration.
