cms -- Creative Music System device driver
cms0 at isa? port 0x220
midi* at cms?
The 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.
The cms device driver appeared in NetBSD 1.5.
