BIOS Setup
DMA Channel 0/1/3/5/6/7
These items specify the bus that the system DMA (Direct Memory Access)
channel is used.
The settings determine if AMIBIOS should remove a DMA from the available
DMAs passed to devices that are configurable by the system BIOS. The avail-
able DMA pool is determined by reading the ESCD NVRAM. If more DMAs must be
removed from the pool, the end user can reserve the DMA by assigning an [ISA/
EISA] setting to it.
