An electronic apparatus and a boot method thereof are provided. The electronic apparatus includes a first controller, a basic input output system (BIOS), and a second controller. The first controller is configured to receive a boot code and provides the boot code to the electronic apparatus for performing a boot operation. The BIOS is configured to provide the boot code. The second controller has at least one communication interface. The at least one communication interface is configured to be connected to at least one external apparatus. The at least one external apparatus provides a backup boot code to the second controller. When the boot operation performed by the electronic apparatus according to the boot code provided by the BIOS fails, the second controller replaces the first controller to receive the backup boot code and provides the backup boot code to enable the electronic apparatus to perform the boot operation.

Electronic apparatus and boot method thereof

An apparatus for waking up a computer system is disclosed. The apparatus is electrically coupled to a south bridge, or a Platform Controller Hub (PCH), having a first USB host interface. The apparatus comprises: a second USB host interface; a switch element, for electrically coupling a USB keyboard to either the first USB host interface or the second USB host interface; a control element, electrically coupled to the second USB host interface and the switch element; and a wake-up element, electrically coupled to the control element, wherein when the computer system enters a suspend-to-ram mode, a suspend-to-disk mode or a shutdown mode, the control element controls the switch element to electrically couple the USB keyboard to the second USB host interface; wherein when a user inputs a password, the second USB host interface receives the password and transfers it to the control element, and if the password matches the predetermined password, the control element wakes up the computer system and controls the switch element to electrically couple the USB keyboard to the first USB host interface.
