Method for quickly booting a computer system

Abstract: A method for quickly booting a personal computer system using boot configuration information on memory and the attached devices that was created and saved in a hard disk at the preceding boot process. The method for a quick boot process includes the steps of performing a power-on self test POST) operation when a personal computer system is powered on or a reset button is pressed; performing a normal boot process after the POST operation; saving the contents of memory and the status of the attached devices to a hard disk; checking if a reboot is requested; restoring the saved boot configuration information from the hard disk, after POST is completed during the reboot process; checking whether or not an initial device configuration file and/or an automatic batch file were changed; and executing commands in the two files and saving a newly created boot configuration information to the hard disk for future boot. The personal computer system, may reboot quickly because of omission of execution of the initial device configuration filed and the automatic batch file.

Gaming machine having a community game with side wagering

Abstract: According to one embodiment of the present invention, a system and method for conducting a wagering game on a plurality of gaming machines is disclosed. The method comprises the act of triggering a community event while conducting the wagering game on the plurality of gaming machines. Two or more gaming machines are selected to participate in the community event. The community event is selected from a plurality of independent community events. The gaming system comprises a plurality of gaming machines, at least one community display, and at least one controller. The controller is operative to select the two or more gaming machines to participate in the community event, and select the community event from the plurality of independent community events to display on the at least one community display.

Non-volatile memory cache performance improvement

Abstract: In order to provide a more efficient persistent storage device, one or more long-term storage media are included along with a non-volatile memory. In one embodiment, one portion of the non-volatile memory is used as a write buffer and a read cache for writes and reads to the long-term storage media. Interfaces are provided for controlling the use of the non-volatile memory as a write buffer and a read cache. Additionally, a portion of the non-volatile memory is used to provide a direct mapping for specified sectors of the long-term storage media. Descriptive data regarding the persistent storage device is stored in another portion of the non-volatile memory.

Systems and Methods for Accelerated Loading of Operating Systems and Application Programs

Abstract: Systems and methods for providing accelerated loading of operating system and application programs upon system boot or application launch are disclosed. In one aspect, a method for providing accelerated loading of an operating system comprises the steps of: maintaining a list of boot data used for booting a computer system; preloading the boot data upon initialization of the computer system; and servicing requests for boot data from the computer system using the preloaded boot data. In another aspect, a method for providing accelerated launching of an application program comprises the steps of: maintaining a list of application data associated with an application program; preloading the application data upon launching the application program; and servicing requests for application data from a computer system using the preloaded application data.

System and method for selective memory module power management

Abstract: A memory module includes a memory hub that monitors utilization of the memory module and directs devices of the memory module to a reduced power state when the module is not being used at a desired level. System utilization of the memory module is monitored by tracking system usage, manifested by read and write commands issued to the memory module, or by measuring temperature changes indicating a level of device activity beyond normal refresh activity. Alternatively, measured activity levels can be transmitted over a system bus to a centralized power management controller which, responsive to the activity level packets transmitted by remote memory modules, direct devices of those remote memory modules to a reduced power state. The centralized power management controller could be disposed on a master memory module or in a memory or system controller.

Disk drive caching initial host requested data in non-volatile semiconductor memory to reduce start-up time of a host computer

Abstract: A disk drive is disclosed comprising a disk for storing initial host requested (IHR) data requested by a host computer during a start-up process of the host computer, a head actuated radially over the disk, and a non-volatile semiconductor memory (NVSM) for caching at least part of the IHR data. The disk drive transmits the cached IHR data from the NVSM to the host computer during the start-up process thereby avoiding the delay associated with initializing the mechanics of the disk drive as well as conserving battery power for mobile applications.
