41 If you don't have a sound card in your computer, you can include a
42 driver for the PC speaker which allows it to act like a primitive

48 WARNING: if you already have a soundcard, enabling this
49 driver may lead to a problem. Namely, it may get loaded
50 before the other sound driver of yours, making the
51 pc-speaker a default sound device. Which is likely not
52 what you want. To make this driver play nicely with other
53 sound driver, you can add this in a configuration file under

195 value, a nonnegative integer that specifies how many
196 seconds of idle time the driver must count before it may
197 put the AC97 into power-save mode; a value of 0 (zero)
198 disables the use of this power-save mode.
