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 log-
ging 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.
POST Error Codes and Messages is a list of the error codes and messages written at the
start of each POST test. The table below lists the 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.
