If your ISA card is not PnP compatible and
requires a special IRQ to support its function, set
the selected IRQ to Legacy ISA. This setting
informs the PnP BIOS to reserve the selected
IRQ for the installed legacy ISA card. The default
is PCI/ISA PnP. Take note that PCI cards are
always PnP compatible (except old PCI IDE
cards).
