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 the
boot-up process. The error messages normally appear on the screen.
Fatal errors 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.
