This section describes the POST error codes, messages, and beep codes.
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 a checksum of zero.
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 5-1
