BIOS Messages
BIOS Beep Codes
Errors may occur during the POST (Power-On Self Test) routines which are performed each time the
system is powered on.
Non-fatal errors
are those which, in most cases, allow the system to continue the bootup process. The
error message normally appears on the screen. See
BIOS Error Messages
later in this section for
descriptions of these messages.
Fatal errors
are those which will not allow the system to continue the bootup procedure.
These fatal errors are usually communicated through a series of audible beeps. Each error message has its
own specific beep code, defined by the number of beeps following the error detection. The following table
lists the errors which are communicated audibly.

Fatal error. Perform the following steps before calling Technical Support.
Remove all expansion cards and try to reboot. If the beep code is still
generated, call Technical Support. If the beep code is not generated, one of
the add-in cards is causing the malfunction. Insert the cards back into the
system one at a time until the problem recurs. This will indicate the
malfunctioning card.
