Abstract

An electronic system including a first electronic device and a second electronic device and a method of switching operating systems thereof are provided. The first electronic device executes a first operating system. The second electronic device executes a second operating system. The operating system switch unit of the first electronic device includes an input and output switch unit and a logic determining circuit unit. The logic determining circuit unit determines whether the second electronic device is connected to the first electronic device to generate the connection information and determines whether to receive switch information which is generated by enabling a switch. The input and output switch unit determines to provide the control right of the peripheral input and output device of the first electronic device to the first electronic device or the second electronic device according to the connection information and the switch information, and the first operating system and the second operating system is selectively executed accordingly. As a result, the operating system of multiple electronic devices, respectively, can be freely switched to be executed at one of the electronic devices via the peripheral input and output device of one of the electronic devices.
