determine if the BIOS 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, the
end user can use these options to reserve the IRQ by assigning an
ISA/EISA setting to it. Onboard I/O is configured by the BIOS. All
IRQs used by onboard I/O are configured as PCI/PnP. IRQ12 only
appears if the PS/2 Mouse Support option in Advanced Setup is set
to Disabled. IRQ14 and 15 will not be available if the onboard PCI
IDE is enabled.
