Beep Codes - Gateway 910 Series System Manual

Beep codes

Whenever a recoverable error occurs during POST, the BIOS displays an error
message describing the problem. The BIOS also issues a beep code (one long
tone followed by two short tones) during POST if the video configuration fails
(a faulty video card or no card installed) or if an external ROM module does
not properly checksum to zero.
An external ROM module (for example, a video BIOS) can also issue audible
errors, usually consisting of one long tone followed by a series of short tones.
For more information on the beep codes issued, check the documentation for
that external device.
There are several POST routines that issue a POST terminal error and shut
down the system if they fail. Before shutting down the system, the
terminal-error handler issues a beep code signifying the test point error. This
beep code consists of one long tone and a series of short tones.
If POST completes normally, the BIOS issues one short beep before passing
control to the operating system.
