Troubleshooting
The POST (power-on self test) performs various diagnostic tests at
the time the system is powered ON. Whenever an error is en-
countered during these tests, either you hear a few short beeps or
see an error displayed on the screen.
Non-fatal errors are those which, in most cases, allow the system
to continue the boot up process. The error messages normallv
appear on the screen.
Fatal errors are those which will not allow the svstcm to continue
the boot up procedure. If a fatal error occurs, you should consult
w i t h your system manufacturer for possible repairs.
These fatal errors are usually communicated through a series of
audible beeps. The numbers on the fatal error list below
correspond to the number of beeps for the corresponding error.
The following error messages are conveyed through a number of
short beeps; you can always identify the error by counting the
number of short beeps.
