POST Code Errors
Most error conditions encountered during POST are reported using
POST Error Codes
. These codes
represent specific failures, warnings, or are informational. 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.
The following table 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:
The error message is displayed on the screen or on the Error Manager screen, and an error 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 does not have any effect
on this error.
•
Major:
The error message is displayed on the Error Manager screen, and an error is logged to the SEL.
The POST Error Pause option setting in the BIOS setup determines whether the system pauses to the
Error Manager for this type of error so the user can take immediate corrective action or the system
continues booting.
For 004
8 “Password check failed”, the system halts, and then after the next reset/reboot will display
the error code on the Error Manager screen.
•
Fatal:
The system halts during post at a blank screen with the text
“Unrecoverabl
e fatal error found.
System will not boot until the error is resolved”
and
“Press <F2> to enter setup”
The POST Error
Pause option setting in the BIOS setup does not have any effect with this class of error.
When the operator presses the
F2
key on the keyboard, the error message is displayed on the Error
Manager screen, and an error is logged to the SEL with the error code. The system cannot boot unless
the error is resolved. The user needs to replace the faulty part and restart the system.
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 determines which of the listed error codes are
supported.
