Post Code Errors
Most error conditions encountered during POST are reported using POST error codes. These codes
represent specific failures, warnings, or information. POST error codes may be displayed in the error
manager display screen and are always logged to the System Event Log (SEL). Logged events are available to
system management applications, including remote and Out of Band (OOB) management.
There are exception cases in early initialization where system resources are not adequately initialized for
handling POST Error Code reporting. These cases are primarily fatal error conditions resulting from
initialization of processors and memory, and they are handed by a diagnostic LED display with a system halt.
lists the supported POST error codes. Each error code is assigned an error type that determines the
action the BIOS takes when the error is encountered. Error types include minor, major, and fatal. The BIOS
action for each is defined as follows:
•
Minor
: An error message may be displayed to the screen or to the BIOS Setup Error Manager and the
POST error code is logged to the SEL. The system continues booting in a degraded state. The user
may wa
nt to replace the erroneous unit. The “POST Error Pause” option setting in the
BIOS Setup
does not affect this error.
•
Major
: An error message is displayed to the Error Manager screen and an error is logged to the SEL. If
the BIOS Setup
option “Post Error Pause” is enabled, operator intervention is required to continue
booting the system. If the BIOS Setup
option “POST Error Pause” is disabled, the system continues to
boot.
Note:
F
or 0048 “Password check failed”, the system halts
and then, after the next reset/reboot,
displays the error code on the Error Manager screen.
•
Fatal
: If the system cannot boot, POST halts and displays the following message:
Unrecoverable fatal error found
.
System will not boot until the error is
resolved.
Press
<F2>
to enter setup.
When the
<F2>
key on the keyboard is pressed, the error message is displayed on the Error Manager
screen and an error is logged to the system event log (SEL) with the POST error code. The system
cannot boot unless the error is resolved. The faulty component must be replaced.
The “POST Error
Pause” option setting in the
BIOS Setup does not have any effect on this error.
Note:
The POST error codes in the following table are common to all current generation Intel® server
platforms. Features present on a given server board/system determine which of the listed error codes are
supported.
