Abstract: Disclosed herein are techniques and equipment for saving game history data and package identification information for software packages used to provide a game cycle on a wager gaming machine. The game cycle may later be re-created using the game history data and software packages. For scenarios where some or all of the software packages used are no longer present on the gaming machine at the time of re-creation, the package identification information may be referenced to determine which software packages are missing and need to be provided to enable full game cycle re-creation.

Abstract: A multi-tiered static chain of trust is established in a computer system which utilizes a first authentication program stored on a first memory device to authentic data stored on a second memory device. If the data stored on the second memory device is authenticated, then a second authentication program stored on the second memory device authenticates data stored on a third memory device. If the data on the third memory device is authenticated the computer system is allowed to utilize the data stored on the third memory device. The data stored on the third memory device is indirectly authenticated while the data is being used by authenticating the data stored on the first memory device.

Abstract: A wager gaming machine having software and components allowing for automatic powering on and off (also referred to as remote out-of-band power control) bypassing the need for human operator intervention is described. The gaming machine has a master gaming controller and a network interface. The interface includes an input port supporting a TCP/IP connection which can be used by another network component having the gaming machine's IP address. The gaming machine may also include a Web server operating on the input port. The Web server may receive HTTP messages on the input port even when the gaming machine is powered off. Thus, the machine is capable of receiving an HTTP message at the input port instructing the machine to power on. The gaming machine may also contain a manageability engine processor for executing an active management system software component. This component implements the Web server on the gaming machine.
