| 20080244250 | Instant on video - 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. | 10-02-2008 |
| 20090006837 | METHOD AND APPARATUS FOR IMPROVED MEMORY RELIABILITY, AVAILABILITY AND SERVICEABILITY - 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. | 01-01-2009 |
| 20090023414 | Software-Defined Radio Support in Sequestered Partitions - 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. | 01-22-2009 |
| 20090063836 | Extended fault resilience for a platform - In one embodiment, the present invention includes a method for allocating a fail-over memory region, determining if multiple processors have reached a rendezvous state, and verifying a memory failure in a system software memory region associated with a non-rendezvousing processor and sending a message to the non-rendezvousing processor to update a range register to the fail-over memory region. Other embodiments are described and claimed. | 03-05-2009 |
| 20090064274 | Dual non-volatile memories for a trusted hypervisor - In one embodiment, the present invention includes a method for executing a first code portion of a pre-boot environment from a first non-volatile memory, authenticating a trusted hypervisor in the first non-volatile memory using the first code portion, executing the trusted hypervisor if the trusted hypervisor is authenticated, and authenticating a basic input/output system (BIOS) present in a second non-volatile memory with the trusted hypervisor and transferring control from the trusted hypervisor to the BIOS if the BIOS is authenticated. Other embodiments are described and claimed. | 03-05-2009 |
| 20090164837 | Reliable memory for memory controller with multiple channels - One embodiment of the invention includes a memory RAS mode whereby a multi-channel memory controller utilizes both memory mirroring and memory sparing to form more complete memory redundancy loss protection. | 06-25-2009 |
| 20090172381 | ENHANCED NETWORK AND LOCAL BOOT OF UNIFIED EXTENSIBLE FIRMWARE INTERFACE IMAGES - Techniques and architectures to provide high assurance image invocation in a pre-boot environment. These techniques may augment implementations of the Unified Extensible Firmware Interface (UEFI) to invoke UEFI images using Trusted Execution Technology (TXT). This can operate to combine pre-boot secure flows, such as UEFI image invocation, with the secure launch instruction set extensions of TXT. This may entail combination of the UEFI StartImage instruction with the SMX leaf SENTER instruction. This may operate to allow original equipment manufacturer (OEM) firmware as a guard and that uses UEFI and TXT access control logic at the same instance to pass control to the operating system (OS). | 07-02-2009 |
| 20090254760 | DATA SECURITY - In one embodiment, a method is provided that may include encrypting, based least in part upon at least one key, one or more respective portions of input data to generate one or more respective portions of output data to be stored in one or more locations in storage. The method of this embodiment also may include generating, based at least in part upon the one or more respective portions of the output data, check data to be stored in the storage, and/or selecting the one or more locations in the storage so as to permit the one or more respective portions of the output data to be distributed among two or more storage devices comprised in the storage. Many modifications, variations, and alternatives are possible without departing from this embodiment. | 10-08-2009 |
| 20110154103 | Performing Redundant Memory Hopping - In one embodiment, the present invention includes a method for receiving an indication of a loss of redundancy with respect to a pair of mirrored memory regions of a partially redundant memory system, determining new mirrored memory regions, and dynamically migrating information stored in the original mirrored memory regions to the new mirrored memory regions. Other embodiments are described and claimed. | 06-23-2011 |
| 20110161726 | SYSTEM RAS PROTECTION FOR UMA STYLE MEMORY - In some embodiments, the invention involves a system and method relating to system recovery in a fault resilient manner by isolating errors associated with the management engine (ME) UMA memory. BIOS logs errors occurring on memory within the system. The ME UMA is invisible to the host OS, so the OS will not be notified about the errors occurring in the ME UMA range. When an error threshold has been reached for a memory unit in which ME UMA resides, ME UMA data is migrated to a previously reserved backup region of memory and the ME is notified of the new ME UMA location. The faulty memory is flagged for replacement at a next maintenance cycle. Embodiments may be applied to workstations that utilize ECC memory protection which utilize AMT (Active Management Technology) and ME UMA. Other embodiments are described and claimed. | 06-30-2011 |
