cms driver provides support for the Creative Music
  System (C/MS). These cards were developed by Creative Labs, the same people
  who designed the SoundBlaster cards. Chips were available for the SoundBlaster
  to make them compatible with CMS.
The CMS cards are only capable of playing basic notes and noises,
    making them suitable for playing midi, but not much else. The output is
    stereo, but the cms driver doesn't support stereo
    control. The cards have external volume control, line-output and
  speaker.
The base I/O port address is usually jumper-selected to 0x220. Valid jumper settings are for 0x210, 0x220, 0x230, 0x240, 0x250 and 0x260. There are no interrupt settings.
cms device driver appeared in
  NetBSD 1.5.
