DMA7

Channel Number: 7

Bus Line: 16-bit only

Typical Default Use: None.

Other Common Uses: Sound cards (high DMA), network cards.

Description: This DMA channel is normally open and available for use by peripherals. It is one of the least used channels in the system and is an alternative location for the "high" sound card DMA channel or other devices.

Conflicts: Few conflicts arise with this channel because there are relatively few devices that can use DMA channels 5, 6 or 7.
