Patent ID: 7076644

Claim:
A method for rapidly switching applications, adapted to a computer system, wherein the computer system comprises a plurality of peripheral devices, and the method comprises the steps of: setting a first hot key for activating a first application relative to the first hot key, the first application corresponds to at least one of the peripheral devices; setting a second hot key for activating a second application relative to the second hot key, the second application corresponds to at least one of the peripheral devices; pressing the first hot key to initialize at least one of the peripheral devices relative to the first application through at least one system BIOS of the computer system and thereby activate the first application; pressing the second hot key to initialize at least one of the peripheral devices relative to the second application through the BIOS of the computer system and thereby activate the second application; and shutting down the first application, wherein peripheral devices not relative to the first application and the second application are not initialized, and the first application and the second application are embedded systems and are switched through the at least one system BIOS.
