DMA Channels 0, 1, 3, 5, 6 and 7
These options allow you to specify the bus type used by each DMA channel.
The Setup screen displays the system option:
DMA Channel # PnP
where # is the DMA Channel number.
Available options are:
PnP
ISA/EISA
IRQ5/IRQ9/IRQ10/IRQ11/IRQ15
These options indicate whether or not the specified interrupt request (IRQ) is available
for use by the system for PCI/Plug and Play features or is reserved for use by option
cards on the ISA Bus. This allows you to specify IRQs for use by legacy ISA adapter
cards.
The IRQ setup options indicate whether AMIBIOS should remove an IRQ from the pool
of available IRQs passed to BIOS configurable devices. The available IRQ pool is deter-
mined by reading the ESCD NVRAM. If more IRQs must be removed from the pool,
you can set the IRQ option to ISA/EISA. On-board I/O is configurable by AMIBIOS;
the IRQs used by on-board I/O are configured as PCI/PnP.
The Setup screen displays the system option:
IRQ# PCI/PnP
where # is the number of the interrupt request (IRQ) available to the option
specified (PCI or ISA).
Available options:
PCI/PnP
ISA/EISA
