E.2 Processor Initialization Error Summary
The following table describes mixed processor conditions and actions for all Intel® server boards and Intel®
server systems designed with the Intel® Xeon® Scalable processor family architecture. The errors fall into one
of the following categories:
•
Fatal
: The system halts with a halt error code on the diagnostic LEDs and a corresponding sequence
consisting of three long flashes and one short flash is sent to the POST Error Code LED. The system
cannot boot unless the error is resolved. The faulty component must be replaced.
•
Major
: If the BIOS Setup option “POST Error Pause” is enabled, the system goes directly to the BIOS
Setup Error Manager to display the error and logs the POST error code to SEL. User intervention is
required to continue booting the system. If the BIOS Setup option “POST Error Pause” is disabled, the
system continues to boot and no prompt for the error is given, although the POST error code is
logged to the BIOS Setup Error Manager and to the SEL.
•
Minor: An error message may be displayed to the screen or to the BIOS Setup Error Manager screen
and the POST error code is logged to the SEL. The system continues booting in a degraded state. The
user may want to replace the erroneous unit. The POST Error Pause option setting in the BIOS setup
utility does not affect this error.

Fatal
Halts with error code “0xE5” on the diagnostic LED.
Sends three long flashes and one short flash to the POST Error LED.
Does not boot until the fault condition is remediated.

Fatal
Halts with error code “0xE5” on the diagnostic LED.
Sends three long flashes and one short flash to the POST Error LED.
Does not boot until the fault condition is remediated.

Fatal
Halts with error code “0xE5” on the diagnostic LED.
Sends three long flashes and one short flash to the POST Error LED.
Does not boot until the fault condition is remediated.

not identical
Fatal
Halts with error code “0xE5” on the diagnostic LED.
Sends three long flashes and one short flash to the POST Error LED.
Does not boot until the fault condition is remediated.

identical
Fatal
Halts with error code “0xE5” on the diagnostic LED.
Sends three long flashes and one short flash to the POST Error LED.
Does not boot until the fault condition is remediated.
Processor
microcode update
failed
Major
Logs the POST error code “81 6x” into the SEL.
If the “POST Error Pause” is enabled in the BIOS Setup, loads the BIOS Error Manager to
present error message “816x: Processor 0x unable to apply microcode update” on the
screen.
If the “POST Error Pause” is disabled in the BIOS Setup continues to boot in a degraded
state.
Processor
microcode update
missing
Minor
•
Logs the POST error code “81 8x” into the SEL.
•
The system continues to boot in a degraded state, regardless of the “POST Error Pause”
setting in the BIOS setup.
•
The Error Manager in BIOS Setup will present the message “818x: Processor microcode
update not found”
