1. In a system comprising a processor, an input device operatively coupled to the processor, a visual display operatively coupled to the processor, an information storage mechanism operatively coupled to the processor, and software executable by the processor for governing operation of the system, a method of operating the system to emulate failure recovery, the method comprising the steps of:

  • receiving into the system an input from the input device;

    responsively to the input received, deciding with the processor to bypass a normal mode of operation of the system, the normal mode providing the system with a first set of graphical user interface capabilities, and to establish a failure-recovery mode of operation of the system in lieu of the normal mode, the failure-recovery mode providing the system with a second set of graphical user interface capabilities, the second set including a subset of the first set of graphical user interface capabilities;

    establishing the failure-recovery mode of operation of the system by loading with the processor, in conjunction with the information storage mechanism, a second configuration of the software for execution by the processor; and

    executing software of the second configuration with the processor to provide the system with a graphical user interface capability of the second set.
