Starting the Diagnostics

To start the diagnostics programs, follow these steps:

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

2.Place the reference diskette in drive A, and close the door of the disk drive.

3.Turn on the computer.

When you turn the power on, the computer performs a self test and then automatically starts the diagnostics program.

The Power-on Self Test

Whenever you turn on or reset the computer, the system performs a built-in diagnostics program 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.

If the self test finds a discrepancy between the equipment installed on the computer and the equipment list maintained by the computer, the system asks you to run the Setup program (on the reference diskette) to change the equipment list.

For a complete description of the power-on self test and any error messages it may produce, refer to Appendix C.
