PCI IRQ Routing
The PCI IRQ Routing sub-menu allows you to set IRQ for PCI devices.
CAUTION: The parameters in this screen are for advanced users only. Typically, you do not need to change
the values in this screen because these values are already optimized.

IRQs. A PCI device cannot use IRQs already in use
by ISA or EISA devices. Use “Auto Select” only if no
