The K2000, unlike the K2500 & K2600, has the OS on a ROM chip which is not upgradable by software. This is also the case for the base objects and expansion objects. The objects are contained in the hardware upgrade and it is not necessary to load them via disk. To upgrade the OS, a chip replacement is necessary, and is best done by our service department. That is why there are no downloadable OS upgrades or object files for the K2000 on their website.
