<P>PROBLEM TO BE SOLVED: To provide a method for updating a BIOS (Basic Input/Output System). <P>SOLUTION: The BIOS is stored in a memory of an electronic device. An embedded controller EC30 is connected to the memory 34 and a processor 32. The processor 32 is connected to the memory 34 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 instruction (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 so as to update the BIOS. <P>COPYRIGHT: (C)2010,JPO&INPIT |
