A gaming system includes circuitry and associated methodology for detection of continuity along one or more sensing paths for determination of the presence and proper seating of one or more component boards to each other and a backplane, having an arbitrary number of couplings. The invention controls voltage to one or more components of the gaming system, enabling selective activation of various components, on one or more of the connected boards, based on the proper seating of component boards to each other and a backplane. The invention implements dynamic configuration of sensing paths (defined by signal paths and signal traversal) and subsequent continuity detection through interfacing connector/port pairs, in combination with specifically placed electronic components and local ground connections along the sensing paths, to control powering selective system components based upon a detection of the presence and proper seating of multiple component boards to each other and a backplane.

Controlling gaming machine power-up

The present invention relates to enabling an operating system software to selectively power cycle one or more components of a wagering gaming system comprising a central processing unit board having one or more central processing units, and one or more central processing unit components. The invention uses a memory comprising a dedicated power cycle control register, a power controller, and digital logic configured to initiate a power cycle of the one or more components of the wagering gaming machine when the operating system writes a predetermined value to the power cycle control register. Upon recognizing the predetermined value to a dedicated power cycle control register used solely for power cycling procedures, digital logic is initiated to terminate voltage supplied to the one or more components of the wagering gaming machine and restore power to the one or more components of the wagering gaming machine, effectively 'cold booting' the selected one or more components of the wagering gaming machine main system board(s) without disrupting voltage supplied to the entirety of other components, including peripheral devices of the wagering gaming system.
