Abstract
A method of rebooting an operating system including a plurality of load modules in a single computer. One load module which is to be operated during rebooting of the operating system is held in a memory, while establishing a state capable of accepting interrupt to be processed by the one load module. All the other load modules are loaded in a memory of the computer. Processing of the interrupt can be executed by the one load module even during rebooting of the operating system.
