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]
4.4.3.2 PCI IRQ Resource Exclusion
Onboard LAN Controller [Enabled]
This field allows you to enable or disable the onboard LAN controller. Keep
the default enabled if you wish to use the onboard LAN feature. Set to
[Disabled] if you installed PCI LAN card. Configuration options: [Disabled]
[Enabled]

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]
