### 4. Information about the DMA channels.

This page displays information about the DMA (Direct Memory Access) Channels. A DMA channel is a direct connection that allows devices to transfer data to and from memory without going through the processor. Typically, i386-architecture systems (PC's) have eight DMA channels (0-7).

The exact information displayed is system-dependent. On some systems, DMA Channel information cannot be displayed yet.

On Linux this information is read from `/proc/dma`, which is only available if the `/proc` pseudo-filesystem is compiled into the kernel. A list of all currently-registered (ISA bus) DMA channels that are in use is shown.

The user cannot modify settings on this page.
