Beep and POST Codes
Beep codes are a series of beeps sent through the speaker
which indicate a problem during the Power On Self Test
(POST). If text appears on the video screen, the M6DPi
has completed POST; any other tone from the speaker
indicates something other than a POST error. These
tones
are not
described in the tables on the following
pages.
The beep error codes are a series of beeps. The duration
of the beep tones are constant, but the length of the
pauses between the beeps varies. For example: a 1-3-3
beep code will sound like one beep, a pause; three beeps
consecutively, another pause and then three more beeps.
One beep code is often misunderstood. If a video card is
not installed or is failing, the system board will generate
a long-short-long-short beep code. This is often inter-
preted as a 1-2-1 beep code. But POST errors always
vary in the length of the pause and not the duration of
the beep tone.
Another way of identifying a POST error is to use a
device called a POST card. This peripheral card is
inserted into one of the ISA slots and has an LED (or
LCD) read out showing the contents of port 80h.
The following tables list all beep codes and POST
routines.
