All of the Nikon subsidiaries have now posted the firmware updates for the D200, D2x, and D2hs. These updates basically consolidate the feature sets of Nikon's top three cameras (as much as can be done) and add support for Image Authentication. Some people have had trouble with some of the update files. First, make sure you really unzip it (rather than just move it from a zipped directory). Second, try downloading from a different Nikon subsidiary if you have troubles.
