DMA5

Channel Number: 5

Bus Line: 16-bit only

Typical Default Use: High DMA channel for sound card.

Other Common Uses: SCSI host adapters, network cards.

Description: This DMA channel is normally taken by the sound card in your PC for its "high" DMA channel. Most sound cards today actually use two DMA channels; one must be chosen from DMAs 1, 2 or 3 (the "low" channel), while the other is selected from a high-numbered channel like this one. Some network cards also use this channel, though others don't use DMA at all.

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

Next: DMA6
