Abstract

Disclosed is a method of using a multimedia audio I/O card to help a personal computer user understand the various beeps and tones indicating different error conditions. The personal computer audio card is capable of executing its' own Power On Self Test (POST) while the personal computer system simultaneously executes the system POST. The audio card must also be capable of sampling the system speaker line (analog) either through digital or analog sampling. System speaker output lines from the system processor board are delivered to the audio card for sampling via a cable. The audio card is capable of driving headphones, external speakers, or the system speaker.

Translating Personal Computer Beeps into Spoken Messages

      Disclosed is a method of using a multimedia audio I/O card to
help a personal computer user understand the various beeps and tones
indicating different error conditions.  The personal computer audio
card is capable of executing its' own Power On Self Test (POST) while
the personal computer system simultaneously executes the system POST.
The audio card must also be capable of sampling the system speaker
line (analog) either through digital or analog sampling.  System
speaker output lines from the system processor board are delivered to
the audio card for sampling via a cable.  The audio card is capable
of driving headphones, external speakers, or the system speaker.

      At power on time, the audio card goes into a "wait and watch"
loop until detecting activity from the system board on the speaker
output line.  The audio card virtually intercepts any beeps intended
for the system speaker.  Beeps will not be heard by the user unless
the audio card allows them to pass thru itself to any of the several
output devices mentioned previously.  When beep activity is detected
from the system board speaker output, the audio card determines what
sequence of beeps is occurring.  In many IBM-compatible personal
computers, the sequence of beeps at power-on indicate various types
of OK or failure conditions.

      For the audio card to recognize the beep sequence, it must
count cycles on the system planar...
