An electronic device has a plurality of selectable capabilities. The capabilities may include CPU speed, NIC speed, various protocols, or, in general, any parameters, characteristics or features which a user might desire to have in the electronic device. The device receives a key, such as from an external licensing authority, and the key specifies which capabilities the device should use to configure itself. The user may have to pay the licensing authority for the key. The electronic device thus can be configured into any one of a plurality of capabilities without having to change any hardware-the user simply purchases a key commensurate with a capability desired by the user.
