Abstract: This invention discloses a method for updating a basic input/output system (BIOS). The BIOS is stored in a memory of an electronic device. An embedded controller (EC) is electrically connected to the memory and a processor. The processor is electrically connected to the memory and executes the BIOS. The method for updating the BIOS includes the following steps. First, a write instruction is sent to the EC. Afterward, the EC receives the write instruction and sends a system management interrupt (SMI) to the processor. Then, the processor receives the SMI and sends an identification code to the EC. Then, the EC receives the identification code and determines whether the identification code matches a security code. If the identification code matches the security code, the EC allows the memory to be writable to update the BIOS.

Abstract: A notebook computer and a keyboard controller thereof are disclosed. A keyboard controller is coupled to a keyboard matrix having first connecting wires, a second connecting wire, and third connecting wires. The first connecting wires intersect the horizontal third connecting wires to form several first intersection points. The first intersection points correspond to several keys on a keyboard. The keyboard identification (second) connecting wire intersects the third connecting wires to form a plurality of second intersection points. Each of the first intersection points has a switch, respectively. States of the second intersection points defines a keyboard identifier. The keyboard controller includes a first group of pins coupled to the first connecting wires, a second group of pins coupled to the third connecting wires, and a keyboard identification output pin coupled to the second connecting wire.
