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 com-
puter has two DMA controllers with four channels on each con-
troller, a total of eight DMA channels.
The following table lists the computer’s DMA channel
