초록
An OS switching method for switching an OS within several seconds in an information processing system is provided. In the information processing system which includes a processor, a main memory, a nonvolatile memory, and a plurality of input/output apparatuses, an OS switcher is executed when power is applied to the information processing system. When a first OS acquires an OS switch command that indicates a switch to a second OS while the first OS is activated and running, the first OS stores identification information of the second OS and information indicating an OS switch in the nonvolatile memory, and performs STR. The OS switcher switches an OS from the first OS to the second OS after the STR is completed. Accordingly, in the system, one OS can be quickly switched to another OS within several seconds, and a previous working environment can be maintained.
