DMA Channel Assignments
Direct Memory Access (DMA) allows some devices to transfer
data to and from memory at high speeds, without using the CPU.
Such devices are each assigned a unique DMA channel. The Sat-
ellite 200 Series computer has two DMA controllers with four
channels on each controller, a total of eight DMA channels.
