POST beep codes
In addition to the beep codes that are described in “POST beep code descriptions” on
page 97, the server might emit beep codes that are described in the following table.
The numbers and hyphens describe the sequence of beeps and pauses. For
example, a 1-2-3 beep code is one beep, a pause, two consecutive beeps, another
pause, and three more consecutive beeps.
