Pci Irq Resource Exclusion - Asus P4S533-VM User Manual

Onboard AC97 Audio Controller [Auto]
[Auto] allows the BIOS to detect whether you are using any modem/audio
device. If a modem/audio device is detected, the onboard modem/audio
controller is enabled; if no modem/audio device is detected, the controller is
disabled. If there are conflicts with the onboard modem/audio controller, set
the appropriate field to [Disabled]. Configuration options: [Disabled] [Auto]

4.4.3.2 PCI IRQ Resource Exclusion

IRQ XX Reserved [No/ICU]
These fields indicate whether or not the displayed IRQ for each field is
being used by a legacy (non-PnP) ISA card. The setting [No/ICU] for an
IRQ field indicates that you are using the ISA Configuration Utility (ICU),
and that this particular IRQ is NOT required by a legacy ISA card. Set the
IRQ field to [Yes] if you install a legacy ISA card that requires a unique IRQ
and you are NOT using ICU. Configuration options: [No/ICU] [Yes]
