When the first OS is operated, the first OS hardware resources and the second OS hardware resources are registered by the first OS. Thereafter when the first OS is operated, the first OS inhibits the registration of an interrupt number already allocated to the second OS I/O device. In response to an interrupt request from a second OS I/O device, the second OS starts operating.
