摘要： Using radio frequency identification (RFID) tags embedded in processors within a computing system to assist in system initialization processing. The RFID tags provide a separate communication path to other components of the computing system during initialization processing, apart from the system interconnect. When the computing system is powered up, each processor in the system may cause its RFID tag to broadcast data regarding the processor's interconnect location and initialization status. The RFID tags may be sensed by a RFID receiver in the Platform Control Hub (PCH) of the computing system, and each processor's interconnect location and initialization status data may be stored in selected registers within the PCH. When the BIOS executes during system initialization processing, the BIOS may access these PCH registers to obtain the processor's data. The interconnect location and initialization status data may be used by the BIOS to select the optimal routing table and to configure the virtual network within the computing system based at least in part on the optimal routing table and the RFID tag data and without the need for interrogating each processor individually over the system interconnect.

摘要： In some embodiments, the invention involves speeding boot up of a platform by initializing the video card early on in the boot process. In an embodiment, processor cache memory is to be used as cache as RAM (CAR). Video graphics adapter (VGA) card initialization uses the CAR instead of system RAM to perform initialization. A portion of the firmware code, interrupt vector tables and handlers are mirrored in the CAR, from flash memory to mimic the behavior of system RAM during the video initialization. VGA initialization may occur before system RAM has initialized to enable early visual feedback to a user. Other embodiments are described and claimed.

摘要： 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.

摘要： A software-defined radio (SDR) capability may be provided in a general purpose, many core processing system by sequestering one or more partitions running on one or more cores and instantiating a communications capability by having discrete SDR functions performed by the sequestered partitions. Each SDR module embodied in a sequestered partition may be independently upgraded without modifying the hardware of the underlying processing system. By executing SDR modules in cores not accessible by application programs and/or an operating system (OS), a better Quality of Service (QoS) may be provided for wireless communications on the general purpose, multi-core processing system. An embodiment comprises isolating a core of a many core processing system as a sequestered partition, loading a software-defined radio module onto the core, and executing the software-defined module to implement wireless communications.

摘要： Methods and apparatus dynamically reconfigure storage or channel capacities in a memory system. A fully-buffered dual in-line memory module (DIMM) is configured for a particular storage capacity and a particular channel capacity. An error may be detected at a memory address in some portion of the DIMM. To resolve the problem, the storage capacity or the channel capacity may be reduced and the DIMM may be dynamically reconfigured according to the reduced capacity. For one embodiment the DIMM may be reconfigured by mapping the portion of the DIMM containing the error as unavailable and taking that portion off-line without taking the entire DIMM off-line. For another embodiment the DIMM may be reconfigured by throttling the DIMM at a reduced frequency. The portion of the DIMM containing the error may be retested at the reduced frequency. If no errors are detected, the DIMM may be made available at the reduced frequency.

摘要： A method, apparatus, system, and computer program product for secure server system management. A payload containing system software and/or firmware updates is distributed in an on-demand, secure I/O operation. The I/O operation is performed via a secured communication channel inaccessible by the server operating system to an emulated USB drive. The secure communication channel can be established for the I/O operation only after authenticating the recipient of the payload, and the payload can be protected from access by a potentially-infected server operating system. Furthermore, the payload can be delivered on demand rather than relying on a BIOS update schedule, and the payload can be delivered at speeds of a write operation to a USB drive.

摘要： Methods, systems and computer program products are disclosed for enhanced system boot processing that is faster to launch the OS because it does not interrogate I/O devices for possible interruption, but that also may be modified to interrogate such devices based on a user selection mechanism. The user selection mechanism may be, for at least one embodiment, a software mechanism such as a control panel module. For other embodiments, the user selection mechanism may be a hardware mechanism, such as a power button or other hardware button or switch. Other embodiments are described and claimed.
