  12 # The [FD] Section is made up of the definition statements and a
  13 # description of what goes into  the Flash Device Image.  Each FD section
  14 # defines one flash "device" image.  A flash device image may be one of
  15 # the following: Removable media bootable image (like a boot floppy
  16 # image,) an Option ROM image (that would be "flashed" into an add-in
  17 # card,) a System "Flash"  image (that would be burned into a system's
  18 # flash) or an Update ("Capsule") image that will be used to update and
  19 # existing system flash.
