Operating system transfer and launch without performing post

Abstract

A device operating method includes saving initial state information of an electronic device. Next, transferring control of the electronic device to a principal operating system. After transferring control and upon receiving an operating system shut down indication signal, transferring control of the electronic device to an alternate operating system without performing a power on self test. An electronic device includes a processor and at least one memory. The memory maintains instructions, in the form of program code, that when executed by the processor causes the processor to save the initial state information of the electronic device. Next, control of the electronic device is transferred to a principal operating system. After the principal operating system has been launched and upon receiving an operating system shut down indication signal, transfer control of the electronic device to an alternate operating system without performing a power on self test.
