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.

Press F1 to retry, using another system diskette if

 

possible. Make sure that the Startup Devices

 

option is correctly specified with the BIOS Setup

 

utility. If the problem persists, consult your

 

supplier or an authorized maintainer.
