2-6. Assigning DMA Channels for ISA Cards
Since ISA cards, both Legacy and PnP may also need to use a DMA (direct memory access)
channel, DMA assignments for this motherboard are handled the same way as the IRQ
assignment process described above. You can select a DMA channel in the PCI and PnP
configuration section of the BIOS setup utility. In the BIOS setup, you should choose "Yes"
for those IRQ's and DMA's you wish to reserve for Legacy cards.
