If the BIOS is incapable of completing loading the BIOS program code and performing system initialization within the preset time, the judgment trigger module sends a trigger signal. After receiving the trigger signal, the write module downloads the available BIOS program codes according to the BIOS identifier, and writes to the BIOS, to overwrite the current data.
