IRQ XX Reserved for Legacy Device [No/ICU]

These fields indicate whether or not the displayed IRQ for each field is being used by an onboard legacy (non-PnP) device. The default value indicates either that the displayed IRQ is not used or that the ISA Configuration Utility (ICU) is being used to determine if a legacy device is using that IRQ. If the IRQ is required by a legacy device, then reserce the IRQ by selecting [Yes]. Otherwise, select [No/ICU] to release the IRQ to OS. Configuration options: [No/ICU] [Yes]
