Because a device may be installed at a different time, it is possiblethat the same resource is assigned to two or more devices.Resource conflicts can result in disorderly or erratic system operation or failureof the system to operate at all. If you suspect that resource conflicts mightexist, check the system and reassign the resources as necessary.
