Appendix C

The built-in permanent memory in your computer (ROM) contains a series

of diagnostics programs. These programs are run automatically by the system
every time you turn on the power. The diagnostics programs check the
internal devices such as the ROM, RAM, keyboard controller, timer, video
controller, diskette driver, and hard disk controller.

When you turn on the power, the computer performs the tests described in

this appendix. If an error is found, an error code and an error message are

displayed. If the error is serious, the computer cancels further checking and
halts system initialization. The error message remains on the screen but the
computer is inoperable.

If the error is not serious, the computer displays an error message and waits
for you to resume further checking. You see this prompt:

Press F1 key to resume

Write down the error message and code number, and then press 

F1 

to

resume. Report the error message and code number to your dealer when

requesting repairs.

The computer first checks its internal devices such as the ROM. If a

malfunction is found, the computer displays an error message. In some cases,

the computer may halt with no further information. If this happens, contact
your dealer as soon as possible.

If the computer finds an error in the system board, this message is displayed:

101-System board error
