Abstract
A plural-OS run system in which a plurality of operating systems (OSs) capable of operating on machines of different architectures, respectively, are allowed to run on one bare machine under the control of one control program (CP) or one control means. The input/output instruction and input/output interrupt of the operating system capable of running on a machine of the same architecture as that of the bare machine are directly executed on the bare machine without need for translation of the format. The input/output instruction and the input/output interrupt of the operating system adapted to run on a machine of the architecture differing from that of the bare machine are allowed to be directly executed while translating the format.
