Appendix C: POST Error Beep Codes
The following table lists POST error beep codes. Prior to system Video initialization, BIOS uses
these beep codes to inform users on error conditions. The beep code is followed by a user
visible code on POST Progress LEDs.

The BMC may generate beep codes upon detection of failure conditions. Beep codes are
sounded each time the problem is discovered, such as on each power-up attempt, but are not
sounded continuously. Codes that are common across all Intel

5000 Series Chipsets are listed in Table 59. Each digit in the code is represented
by a sequence of beeps whose count is equal to the digit.
Code
1-5-2-1
CPU: Empty slot / population error – Processor
slot 1 is not populated.
1-5-2-2
CPU: No processors (terminators only)
1-5-2-3
CPU: Configuration error (e.g., VID mismatch)
1-5-2-4
CPU: Configuration error (e.g., BSEL mismatch)
1-5-4-2
Power fault: DC power unexpectedly lost (power
good dropout)
1-5-4-3
