Beep codes
The computer uses special audio beep codes to signal certain
hardware faults. If you hear a beep code which is not accompanied
by a POST error message, call your supplier or authorized
maintainer.
Failure to boot
On completion of POST, the computer attempts to boot from a
system diskette or bootable hard disk partition. The table below lists
some of the messages that might appear during the boot sequence.
