PROBLEM TO BE SOLVED: To provide a system for enabling one computer to easily run a plurality of OSs at the same time only with software relative to a complicated and great-overhead OS control system of a conventional virtual computer system. SOLUTION: A plurality of OSs are run at the same time through the steps of: dividing hardware resources managed by a first OS and another OS; initiating the other OS; switching the active OS; and determining an OS to perform interruption processing in accordance with an interruption factor and initiating an appropriate interruption handler. According to the present invention, a new function of operation completely independent of the first OS can be perfectly integrated into a computer, thereby achieving reduction of an interruption response time, improvement in reliability and the like.
