INFORMATION PROCESSOR, ITS CONTROL METHOD AND MONITOR PROGRAM

摘要

A snap shot for solving a cause of a failure in a first operating system (OS) is acquired while a processing of the OS is continued. In an information processor having a processor provided with a physical register, first information which the first OS uses is kept in the physical register, and the processor changes information kept in the physical register from second information which a monitor program uses to the first information which the first OS uses. The processor refers to the first information kept in the physical register.
