Appendix B
Power-on Diagnostics
Your computer’s built-in memory (ROM) contains a series of
diagnostics programs, which your computer runs automatically
every time you turn on the power. These programs check
internal devices such as ROM, RAM, the timer, the keyboard
controller, and the diskette drives.
When you turn on the power, the computer performs the tests
described in this appendix. If it finds an error, it displays a
specific error number and error message on the screen.
If the error is serious, the computer cancels further checking
and halts system initialization. The error message remains on
the screen, and the computer locks up. If this happens, contact
your dealer as soon as possible. Report both the error message
and code number.
If the error is not serious, the computer waits for you to resume
further checking. You see this prompt:
(Resume "F1"
Write down the error message and code number, and then press
F1
to continue. Report the error message and code number to
your dealer when requesting repairs.
System Device Check
The computer first checks its internal devices, such as ROM. If
it finds a malfunction, it displays an error message. In some
cases, the computer may halt with no further information.
