POST Error Codes and Messages
Tables 23 and 24 define the POST error codes and their associated messages. The BIOS prompts
the user to press a key in case of serious errors. Some error messages are preceded by the word
"Error" to highlight the fact that the system might be malfunctioning. All POST errors and
warnings are logged in the SEL, unless the SEL is full.
