DMA Channel
To select a DMA Channel (5,6,or 7), install the jumpers over the pair of DMA channel pins. If
you use an 8-bit slot, you must use pseudo DMA. Pseudo DMA provides a form of software controlled
DMA. Pseudo DMA is not as fast as DMA provided by hardware, but it is helpful if a 16-bit slot
is not available.
If your computer does not have a standard ISA bus, it may be necessary to use pseudo DMA even though you are using a 16-bit
slot. To use pseudo DMA remove all DMA jumpers.
