Abstract

PURPOSE:To eliminate the replacement processing of overlapping memory areas to quickly switch an OS by assigning each of OSs to be operated on the same system to an independent memory area. CONSTITUTION:When an operation end request is accepted by an OS switching request accepting means 2, a control means 3 terminates the operation of the system; and when plural OSs are read in by a multi-OS reading-in means 1 and an OS switching request is accepted by the OS switching request accepting means 2 in this state, the control means 3 starts the switching control from the OS operated at present to the OS to be next operated. An OS control information preserving means 4 where control information of the OS to be operated at present is preserved, an OS control information restoring means 5 which restores control information of an OS, an OS switching means 6, etc., are provided. Thus, OSs to be operated on the same system are assigned to memory areas independent of one another to quickly switch OSs.

(A) An auxiliary storage section that stores and provides usable OSs in advance, (B) A main storage section that has an OS reading memory area with a capacity that can read multiple OSs, (C) A storage section that stores multiple OSs. an OS reading section that reads from the auxiliary storage section and stores it in an OS reading memory area of the main storage section; (D) an operation for accepting an OS switching request including the name of the OS to be operated next and terminating the operation of the system; an OS switching request receiving unit that receives a termination request; (E) an OS control information register unit having a register that holds various control information for operating the OS; and (F) an OS switching request receiving unit that receives an OS switching request. (G) Following the operation of the OS control information storage section, the OS control information storage section stores the control information of the operating OS from the OS control information register section to the main storage section;
The control information for the next OS to be operated having the OS name accepted by the S switching request receiving unit is transferred from the main storage unit to the OS.
an OS control information return unit that returns the OS control information to the control information register unit;
When the S switching request receiving section receives an OS switching request, the OS control information storage section and the OS control information restoration section are activated in sequence, and the OS name received by the OS switching request receiving section is changed from the operating OS. an OS switching method, comprising: a control unit that causes the system to transition to the next OS to be operated, and terminates the operation of the system when the OS switching request receiving unit receives an operation termination request.
