FIRMWARE UPDATING
File
Updating the file of a base version.
Updating the version by means of the package of only the
files which have been changed from the base. This
method is applied to the system firmware only. Since only
the files which have been changed are packaged, the
data size is smaller than that for the standard package.
Updating can be done in a shorter time than the standard
one. This method is applied to the system firmware and
the system software only.
