A method and system for updating a boot block of a Basic InputOutput System program in an electronic device to prohibit write processes to the boot block while realizing update of contents stored therein. The lid assembly includes a lid member with a first opening there through adapted to fit onto the rotatable atomizer wheel over the atomizing chamber. throughput, offered to the user and an average preceding value of the transmission parameter provided to the user within a predetermined time period. The blind rail can be placed into the main support body through the open side thereof and supported by the main support body. The exposed segments of the annular features may define a plurality of openings, and such openings may be transferred into the material to form openings extending to the electrically conductive lines. Film air is supplied into the combustion volume downstream of the main nozzles along the inner surface of the side wall to reduce the fuel-air ratio in a region adjacent the inner surface of the side wall and to restrain a combustion-driven oscillation in the combustion volume.
