Primary Graphics Adapter:
The settings made on this field identify the type of display
controller used in the system. The available choices are Auto,
Internal, and External AGP/External PCI.
Allocate IRQ to PCI VGA:
Set this option to Yes when allocating an IRQ to the VGA device
on the PCI bus. The available settings are Yes, and No.
DMA Channel 0/1/3/5/6/7:
These options allow you to specify the bus type used by each
DMA channel. The available settings are PnP, and ISA/EISA.
IRQ3/4/5/7/9/10/11/14/15
These options specify the bus on which the specified IRQ line is
used. The options allow you to reserve IRQs for legacy ISA
adapter cards. The options also determine if AMIBIOS should
remove an IRQ from the pool of available IRQs passed to devices
configurable by the system BIOS. The available IRQ pool is
determined by reading the ESCD NVRAM. If user needs to
remove more IRQs from the pool, he can use each option to
reserve the IRQ by assigning an ISA/EISA setting to each.
Onboard I/O is configured by AMIBIOS. All IRQs used by onboard
I/O are configured as PCI/PnP.
