Error Messages
This section describes the POST error codes and messages.
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.

written at the start of each POST test. Table 5-2
