Appendix F: POST Error Code 
Most error conditions encountered during POST are reported using POST Error Codes. These 
codes represent specific failures, warnings, or informational messages that are identified with 
particular hardware units. These POST Error Codes may be displayed in the Error Manager 
display screen, and are always automatically logged to the System Event Log (SEL). Being 
logged to SEL means that the error information is available to System Management 
applications, including Remote and Out of Band (OOB) management. The table below lists the 
supported POST Error Codes, with a descriptive Error Message text for each. There is also a 
Response listed, which classifies the error as Minor, Major, or Fatal depending on how serious 
the error is and what action the system should take. The Response column in the following 
table indicates one of these actions: 
  Minor: The 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 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. 
  Fatal: The system halts during post at a blank screen with the text Unrecoverable 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 
on this class of error.
