   6 # firmwares like this:
   7 # orig-firmware/
   8 #               h1xx/
   9 #                    1.66jp/

  11 #                           ihp_100.hex
  12 #                           ihp_120.bin
  13 #                           ihp_120.hex

  17 #                           H300.hex
  18 # etc.
