It means that the ACPI PCI Routing Table (_PRT) did not have an entry for this PCI device. This is very common for IDE, which can't decide if it is a real PCI device or a legacy device; and the driver is hard-coded to IRQ14, 15 anyway. Linux is actually sort of exposed WRT motherboard devices, because while Linux/ACPI finds the PCI resources, it doesn't look for the legacy resource, which is where on this board IDE lives. -Len
