BIOS error beep codes
During 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 the boot-up process. The error messages normally appear on
the screen.
Fatal errors are those which will not allow the system to continue the
boot-up procedure. If a fatal error occurs, you should consult with
your system manufacturer for possible repairs.
