Here is a post I saved late last century a regular poster called 'pyats' to
the alt.windows95 ng. Hope this helps.

"Beep codes are a series of beeps through the speaker that indicate
a problem during POST (Power On Self Test).  If text appears on
the video screen, the motherboard has completed POST; any other tone
from the speaker indicates something other than a POST error.  These
tones are not described in the following table.

The beep error codes are all a series of three sets 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 run together, another pause, and
then three more beeps run together.

There is one beep code that is often misunderstood.  With no video card
installed, or if the video card is failing, the motherboard will
generate a long-short-long-short beep code.  This is often misinterpreted
as a 1-2-1 beep code, but POST errors always vary 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.
