3.7.3 Assigning DMA Channels for ISA Cards

Some 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 earlier. To select a DMA channel, see PCI/
PNP ISA DMA Resource Exclusion in 4.4.3 PCI Configuration. NOTE: The on-
board audio by default uses DMA1.
IMPORTANT:
legacy ISA cards (see PCI/PNP ISA IRQ Resource Exclusion and PCI/PNP
DMA IRQ Resource Exclusion in 4.4.3 PCI Configuration). Choose Yes in
IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you
want to reserve).

3.7.4 Audio Modem Riser (AMR) Slot

This connector supports a specially designed audio and/or modem card called an AMR.
Main processing is done through software and controlled by the motherboard's Intel
Controller Hub (ICH). This provides an upgradeable audio and/or modem solution at
an incredibly low cost. There are two types of AMR, one defined as primary and
another defined as secondary. This motherboard does not support secondary AMR
cards. When using a primary AMR audio card, the motherboard's onboard PCI audio
must be disabled.
NOTE: An AMR is not included with this motherboard.
