Hi All,

For rather complex solution:

# kldload speaker
# chmod 660 /dev/speaker

Checkout source code for battd utility in DragonFly
(http://dragonflybsd.org/cvsweb/src/usr.sbin/battd/).  Compile, install
and run it with something like:

$ battd -p 10 -e $HOME/bin/beep_speaker

And where $HOME/bin/beep_speaker:

#/bin/sh
TUNE="l2b.f+.p16a.c+.p l4mn<b.>e8a2mspg+e8c+f+8b2"
/bin/echo $TUNE > /dev/speaker

Which will play "opening bars of the theme from Star Trek Classic" when
the battery will reach approximately 10%.  There are more tunes in
src/usr.sbin/spkrtest/spkrtest.sh, and you can always make your own ;-).

A long string of 'A's will produce unpleasant beeping, which will remind
you to turn on turn on your power supply :-).

HTH.
