POST Error Codes and Messages
Table 10-4 and Table 10-5 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 server might be malfunctioning. All POST errors and warnings are logged in the
SEL, unless the SEL is full.
