A6A0 DXE Boot Services driver: Not enough memory
available to shadow a Legacy Option ROM
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.
Beeps Error Message
1 USB device action
1 long Intel® TXT security

3 Memory error
3 long CPU mismatch

The following Beep Codes are sounded during BIOS Recovery.
2 Recovery started
4 Recovery failed
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.
Code
1-5-1-2 VR Watchdog Timer sensor assertion
1-5-1-4 The system does not power on or
unexpectedly power off and a power
supply unit (PSU) is present that is an
incompatible model with one or more
other PSUs in the system
1-5-2-1 No CPUs installed or first CPU socket is
empty
1-5-2-2 CPU CAT Error (IERR) assertion
1-5-2-3 CPU ERR2 timeout assertion
1-5-2-4 CPU Icc max Mismatch
1-5-2-5 CPU population error
1-5-4-2 Power fault: DC power is unexpectedly
lost (power good dropout).
1-5-4-4 Power control fault (power good
assertion timeout).

Reason for Beep
Action message
Please disable OpRom at SETUP to save
runtime memory.
Description
Short beep sounded whenever USB device is
discovered in POST, or inserted or removed during
runtime.
System halted because Intel® Trusted Execution
Technology detected a potential violation of system
security.
System halted because a fatal error related to the
memory was detected.
System halted because a fatal error related to the
CPU family/core/cache mismatch was detected.
Recovery boot has been initiated.
Recovery has failed. This typically happens so quickly
after recovery is initiated that it sounds like a 2-4
beep code.
