  • Switching CPU execution path during firmware execution using a system management mode
    Patent number: 10055234
    Abstract: A computer system firmware is provided that includes functionality for using a system management mode (SMM) to efficiently boot to a secondary operating system prior to booting to a primary operating system. The SMM is utilized to store data describing the state of the computer system at a point just prior to booting the secondary operating system. This data is used following execution of the secondary operating system to restore the system to the same state that it was in prior to executing the secondary operating system. Execution can then be continued at a location just following the location at which the secondary operating system was booted in order to execute a primary operating system.
