Error Messages
This section details the POST error codes and messages, and the meaning of the
diagnostic LEDs colour combinations.
POST Error 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.
The Response section in the following table is divided into two types:
■ Pause: the message is displayed in the Error Manager screen, an error is logged to
the SEL, and user input is required to continue. The user can take immediate
corrective action or choose to continue booting.
■ Halt: the message is displayed in the Error Manager screen, an error is logged to
the SEL, and the system cannot boot unless the error is resolved. The user needs to
replace the faulty part and restart the system.
POST Error Beep Codes
The following table lists POST error beep codes. Prior to system Video initialization,
BIOS uses these beep codes to inform users on error conditions. The beep code is
followed by a user visible code on the diagnostic LEDs.
