By putting the device configuration line into your kernel config file: device pca0 at isa? port IO_TIMER1 tty It operates on the normal PC speaker, but naturally, its sound is rather terrible, and it puts a fair amount of load onto the machine by drastically increasing the timer interrupt rate. The device node /dev/pcaudio is supposed to be created by default. If you are adventurous, you can symlink it to /dev/audio, so other programs will believe you've got a Sun /dev/audio compatible sound device. The implementation used to have several glitches. Some of the most serious have been fixed right in time before 2.1.5, quite some other ones only later in 2.2-current (by July 20, 1996). So if you try playing XBoing over it, you will note several minor anomalities even in FreeBSD 2.1.5. In FreeBSD 2.1, don't be surprised if the system hangs or crashes at all when you're doing this. (Dumping single .au files to /dev/pcaudio used to work, but XBoing opens/writes/closes the sound device again for each new sound, so it puts much more load on it.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
