Appendix C

The built-in memory (ROM) of your computer 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

ROM, RAM, keyboard controller, timer, video controller, and

floppy disk driver.

When you turn on the power, the computer performs the

tests described in this appendix. If an error is found, a specific
error number and 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:

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

possible.

If a fault in the main board is found, the computer stops

and this error message is displayed:
