    hardware-initiated reset

    Explanation:

    In order to properly switch it back to real address mode operations you need to perform a hardware-initiated reset. This is because once in protected mode the 80286 will remain there until the hardware itself is reset. Therefore manually reseting the hardware will allow the user to switch back the microprocessor into a real address mode operations.
