POST Error Codes and Messages

Whenever a recoverable error occurs during POST, BIOS displays a message on the video display screen and causes the speaker to beep as the message appears. BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails or if an external ROM module does not have the correct checksum. The BIOS indicates errors by writing an error code to the PS/2-standard logging area in the Extended BIOS Data Area, and by displaying a message on the screen, which is sometimes preceded by the POST Error Code. The error code will also be logged to the Event Logging area.

Table 5-1POST Error Codes and Messages is a list of the error codes and messages written at the start of each POST test. Table 5-2 POST Error Beep Codes is a list of beep codes issued for each POST test. The devices associated with the POST error codes are shown in subsection POST Error Code Hardware References that follow.
