Troubleshooting
BIOS POST Beep Codes
The table below lists the POST error beep codes. Prior to system video initialization, the BIOS uses
these beep codes to inform users of error conditions. Please note that not all error conditions are
supported by BIOS beep codes.
Table 7. POST Error Beep Codes
Number of
Beeps Reason for the beeps and action to take
1, 2, or 3 Memory error. Reseat the memory or replace the DIMMs with known good
modules.
4 – 7 or 9 – 11 Fatal error indicating a possible serious system problem. Remove all add-in
cards and re-start the system. If the error still occurs, contact your system
manufacturer. If the beep codes are not generated after the add-in cards are
removed, insert the cards one at a time, booting the system between each card
addition, until the beeps again occur to reveal the malfunctioning card.
8 Replace or reseat the system video add-in card. If on-board video is bing used,
the server board may be faulty.
In addition to the beep codes above, additional beep codes are provided if an Intel®
Management Module is installed. The Intel Management Modules provide the following
additional beep codes.
