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.
