problem configuring sb16 and alsa

[Kerry Hoath]

The dma16 value must be above 4.
Dma channels 0 1 2 and 3 are 8-bit,
4 5 6 and 7 are 16-bit.
4 is reserved to cascade back to the primary dma controller,
5 6 and 7 are available for u se.
Dma2 is used by the floppy drive unless you put
floppy=nodma on your kernel command-line,
not recommended it slows the system down a treat w hen you access floppies.
Dma0 is used on older systems as the ram refresh channel, modern boards do
this in t he firmware using hidden refresh so dma0 is available.
If you allocate something to dma0 and your machine locks up, go enable hidden
refresh or use dma 1 or 3.

Summary: channels 0-3 are 8-bit, 4-7 are 16-bit.

Regards, Kerry.
