Computer platform embedded operating system backup switching handling method and system

摘要

A computer platform embedded operating system backup switching handling method and system is proposed, which is designed for use with a computer platform for providing an embedded operating system backup switching handling function, and which is characterized by the provision of an operating system health status flag for indicating whether the embedded operating system code has been previously successfully loaded, such that the next time the computer platform is started, the operating system health status flag can be checked to see if the embedded operating system code is corrupted; if YES, a backup copy of operating system code is used for booting. This feature allows the computer platform to more quickly judge whether the embedded operating system code is corrupted, without having to use the more time-wasting checksum method, so that the booting of the computer platform can be more efficiently carried out.
