Appendix D: POST Error Messages and Handling
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
are listed in Table 48. 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
Chipset control failure
1-5-4-4
Power control fault
