Virtually all recent systems support Plug and Play (PnP) hardware with automatic resource allocation by a combination of the PnP BIOS and Windows. However, if you need to determine the hardware resources in use in a particular system, click View and select Resources by type. For example, a typical XP system and its ACPI power management enables IRQs above 15, and sharing of PCI IRQs 17, 20, 22, and 23 by multiple devices.
