BIOS
support non-compliant PCI IDE adapter cards.
OffBoard PCI IDE Primary IRQ
This option specifies the PCI interrupt used by the primary IDE channel on the
offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,
INTB, INTC, or INTD.
Offboard PCI IDE Secondary IRQ
This option specifies the PCI interrupt used by the secondary IDE channel on
the offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,
INTB, INTC, or INTD.
PCI Slot n IRQ Priority
These options specify the IRQ priority for PCI devices installed in the PCI
devices installed in the PCI expansion slots. The settings are Auto, IRQ 3, 4, 5,
7, 9, 10, and 11, in priority order.
DMA Channel n
These options allow you to specify the bus type used by each DMA channel.
The settings are PnP or ISA/EISA .
IRQn
These options specify the bus that the specified IRQ line is used on. These
options allow you to reserve IRQs for legacy ISA adapter cards. These options
determine if AMIBIOS should remove an IRQ from the pool of available IRQs
passed to devices that are configurable by the system BIOS. The available IRQ
pool is determined by reading the ESCD NVRAM. If more IRQs must be
removed from the pool, you can use these options to reserve the IRQ by
assigning an ISA/EISA setting to it. Onboard I/O is configured by AMIBIOS.
All IRQs used by onboard I/O are configured as PCI/PnP. IRQ12 only appears
if the Mouse Support option in Advanced Setup is set to Disabled. IRQ14 and
15 will not be available if the onboard PCI IDE is enabled. If all IRQs are set to
ISA/EISA and IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ9 will
still be available for PCI and PnP devices, because at least one IRQ must be
available for PCI and PnP devices. The settings are ISA/EISA or PCI/PnP.
Reserved Memory Size
This option specifies the size of the memory area reserved for legacy ISA
adapter cards. The settings are Disabled, 16K, 32K, or 64K.
