A method of fabricating an N-type Schottky barrier SourceDrain Transistor with ytterbium silicide for source and drain is presented. The working image is displayed on a display screen in a quick review mode of operation in response to a quick review signal entered by the camera operator via a camera control interface to control processing circuitry of the camera. When the server receives a subsequent request which requires access to the saved variables, they are retrieved for execution of the subsequent service request. Additionally, different versions of file system configuration data may be stored and different hosts accessing the file system may read and use different versions of the file system configuration data based upon the type or context of the host accessing the file system.
