Abstract: 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.

Abstract: A peripheral interface chip and a data transmission method thereof are provided. The peripheral interface chip includes a switching circuit, a universal serial bus (USB) host controller, a keyboard controller and a microprocessor. The switching circuit receives a device identification transmitted from a USB device, and the device identification is used for determining whether the USB device is a keyboard device. When the USB device is the keyboard device, input data of the USB device is transmitted to a controller hub through a first USB interface, the switching circuit, the USB host controller, the microprocessor, the keyboard controller and a low pin count (LPC) interface.
