POST Error Beep Codes
The following table 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.
Table 80. POST Error Beep Codes
Beeps Error Message POST Progress Code Description
1 USB device action NA Short beep sounded whenever a USB device is discovered
in POST, or inserted or removed during runtime
1 long Intel
TXT security
violation
0xAE, 0xAF System halted because Intel
Trusted Execution
Technology detected a potential violation of system
security.
3 Memory error Multiple System halted because a fatal error related to the memory
was detected.
The following Beep Codes are sounded during BIOS Recovery.
2 BIOS Recovery
started
NA Recovery boot has been initiated
4 BIOS Recovery
failure
NA BIOS recovery has failed. This typically happens so quickly
after recovery us 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 the following table. Each digit in the code is
represented by a sequence of beeps whose count is equal to the digit.
