A fence alarm for detecting and identifying a location in a fence which is broken. The solder resist 4 laminated to the top surface of the printed-wiring board 1-1 forms a raised portion 40 in a semiconductor chip mounting area such that the thickness of the raised portion is greater than the thickness of the solder resist 4 laminated to areas other than the semiconductor chip mounting area, so that the surface of the semiconductor chip mounting area is flat. The system also can include a translation server coupled to the aggregator. The handler engine monitors, and responds, to an attempted mode transition of the processor between the hypervisor and supervisor modes, and coordinates the suspension and resumption, as appropriate, of the persistent hypervisor.
