Methods and apparatus to facilitate fast restarts in processor systems are disclosed. An example processor restart method disclosed herein includes recording a log of pre-boot initialization actions, and replaying a portion of the log during subsequent processor restarts to shorten pre-boot initialization time. The example processor restart method disclosed herein may further include creating a log index table for easier referral to portions of the log, storing the log and the log index table in non-volatile memory, using the log index table to reorder the replaying of the log, and reordering the replay of the log to initialize the video graphics adapter earlier in a processor restart sequence.

Methods and apparatuses of configuring a computer system. During a runtime stage or a preboot stage, a device driver for a configurable device exports a set of the configuration information that is resident the buffer during the preboot stage of the computer system. The configuration information is retrieved. The configuration information for said configurable device includes information enabling a callback operation, which allows an operator to dynamically interact with said configurable device. A homepage including a configuration menu for said configurable device is generated and presented to the operator to make configuration selections. The homepage is generated based on the information contained in the buffer. The configuration selections are communicated to the device driver. The configuration selections for said configurable device in a nonvolatile storage module included within said computer system.

A method and apparatus is described herein for performing parallel memory migration, as well as execution of management tasks over a plurality of management windows. Handlers are dispatched to multiple resources, such as processing elements or threads, to determine a proper memory migration handler. Each resource, during a management mode, executes a designated memory migration handler or an instance of a memory migration handler to perform a portion of a memory migration task in parallel. A task data structure is capable of supporting tracking of portions of memory migrated. In addition the task data structure is potentially also capable of tracking management tasks through plurality of management windows to support servicing of management tasks through multiple management windows.

Technologies for broadcasting management information include a management server and a number of client devices. The management server encodes management data such as a certificate revocation list into a number of message fragments using a fountain code encoding algorithm and broadcasts the message fragments continually over a network. Each client device analyzes the network during a boot process to receive the broadcast message fragments. Each client device decodes the message fragments using a fountain code decoding algorithm and determines whether the message is complete. If the message is complete, the client device parses the message to retrieve the management data and may install the management data on the client device. If the message is incomplete, the client device may store the message fragments in nonvolatile storage for processing during future boot events. The client device may perform those operations in a pre-boot firmware environment. Other embodiments are described and claimed.

A method and system for improving responsiveness of a vehicle computing platform includes enabling a camera feature during the pre-boot phase of a computing device and using a special-purpose operating mode of the computing device to initiate the streaming of camera image data to a display.
摘要:
Methods and systems to perform a computer task in a reduced power consumption state, including to virtualize physical resources with respect to an operating environment and service environment, to exit the operating environment and enter the service environment, to place a first set of one or more of the physical resources in a reduced power consumption state, and to perform a task in the service environment utilizing a processor and a second set of one or more of the physical resources. A physical resource may be assigned to an operating environment upon an initialization of the operating environment, and re-assigned to the service environment to be utilized by the service environment while other physical resources are placed in a reduced power consumption state.

Methods and apparatus for providing seamless functionality in a computer are disclosed. For example, an encrypted file system manager is included to layer an encoded File Allocation Table on top of a disk and to pass to the operating system an Embedded Root Key to provide access to an encrypted Firmware Interface System Partition.
摘要:
Methods and apparatuses for re-instantiating a firmware environment that includes one or more firmware functions available at pre-boot time when transitioning the computing device from a wake state to a sleep state. A network event received by the computing device while in a sleep state may be handled by the firmware environment independent of the operating system and without returning the entire computing device to the wake state.
摘要:
A network interface card with read-only memory having at least a micro-kernel of a cluster computing operation system, a server formed with such network interface card, and a computing cluster formed with such servers are disclosed herein. In various embodiments, on transfer, after an initial initialization phase during an initialization of a server, the network interface card loads the cluster computing operation system into system memory of the server, to enable the server, in conjunction with other similarly provisioned servers to form a computing cluster. Other embodiments are also disclosed and claimed.
