These options specify the bus or the PCI slot range that the specified IRQ line is
used on. They allow you to reserve IRQs for legacy ISA adapter cards. You can
also specify the IRQ used for each group of PCI expansion slots. The Goliath
base board has two groups of PCI expansion slots: The primary group (PCI
expansion slots 1, 2, and 3) and the secondary PCI expansion slots (PCI
expansion slots 4, 5, and 6). All IRQs are available to the primary PCI slots.
The IRQ pool for the secondary PCI slots is: IRQ3, IRQ5, IRQ7, IRQ10, and
IRQ15. Make sure that at least one of these IRQs is reserved for the secondary
PCI slots if you have installed a PCI adapter card in PCI expansion slot 4, 5, or
6.
These options determine if AMIBIOS should remove an IRQ from the pool of
available IRQs passed to devices that can be configured by the BIOS. The
available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs
must be removed from the pool, set these options to reserve the IRQ by
assigning an ISA setting to it. Onboard I/O is configured by AMIBIOS. All
IRQs used by onboard I/O are configured as PnP. IRQ12 only appears if the
Mouse Support option in Advanced Setup is set to Disabled. IRQ14 will not be
available if the Onboard Primary IDE Controller option is set to Enabled. If all
IRQs are set to ISA and IRQ14 is allocated to the onboard PCI IDE, IRQ9 will
still be available for PnP devices, since at least one IRQ must be available for
PnP. The settings are ISA, Prim-Slots, or Sec-Slots.
