Appendix A
BIOS Error Beep Codes
During the POST (Power-On Self-Test) routines, which are performed
each time the system is powered on, errors may occur.
Non-fatal errors
are those which, in most cases, allow the system to
continue with bootup. The error messages normally appear on the screen.
Fatal errors
will not allow the system to continue to bootup. If a fatal
error occurs, you should consult with your system manufacturer for
possible repairs.
The fatal errors are usually communicated through repeated patterns of
audible beeps. Each pattern of audible beeps listed below corresponds
to its respective error.
