PCI Configuration Submenu 3
The PCI Configuration submenu has only one selection: the IRQ Reservation submenu. The IRQ
Reservation submenu allows you to reserve specific IRQs that are used by legacy devices. Unless you
need to reserve specific IRQs to resolve a resource conflict, the recommended setting for each of these
options is Available.
