RAR archive of firmware for the MS-5500 Ferrari, 4.24 MB, carrying no version, date or revision in its name. It is slightly smaller than the MS-4500 and MS-6000 Ferrari packages, so the contents may differ from theirs. A technician would use it to update a unit or to recover one with corrupted software after checking the archive contents. Confirm the model on the device label and the board first. Make a backup of the existing firmware before flashing so you can return to it.
