POST Error Beep Codes
Table 57 lists the POST error beep codes. Prior to system video initialization, the BIOS uses these beep
codes to inform users on error conditions. The beep code is followed by a user-visible code on the POST
progress LEDs.

Error Message
POST Progress Code
Description
1 short
USB device action
N/A
Short beep sounded whenever USB device is discovered in POST,
or inserted or removed during runtime.
1 long
Intel® TXT security
violation
AE, AF
System halted because Intel® Trusted Execution Technology
detected a potential violation of system security.
3 short
Memory error
Multiple
System halted because a fatal error related to the memory was
detected.
3 long
and 1
short
CPU mismatch error
E5, E6
System halted because a fatal error related to the CPU
family/core/cache mismatch was detected.
2 short
BIOS recovery
started
N/A
BIOS recovery boot has been initiated.
4 short
BIOS recovery failed
N/A
BIOS recovery has failed. This typically happens so quickly after
recovery is initiated that it sounds like a 2-4 beep code.
The integrated 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 server boards and systems that use same generation chipset are
listed in Table 58. Each digit in the code is represented by a sequence of beeps whose count is equal to the
digit.
