It has a builtin sound card on the motherboard, apparently a soundblaster clone of some sort on the ISA bus. FreeBSD Audio Driver (newpcm) Nov 15 1999 14:52:14 Installed devices: pcm0: at io 0x220 irq 5 drq 0:1 (1/1 channels duplex) ^^^^ (do I have to worry here ?) I have current sources from a few days ago and configured newpcm as follow. The card is recognised at boot time w/o problem. Everytime I try to use mpg123 to play some music, the machine panic with "unaligned write 1522, 4". Note that using device pcm0 at isa0 port 0x220 irq 5 drq 1 flags 0x10 OR device pcm0 at isa? port ? irq 5 drq 1 flags 0x10 doesn't make any difference.
