    摘要： A method and apparatus for improving the resume time of a platform. In one embodiment of the invention, the context of the platform is saved prior to entering an inactive state of the platform. When the platform is switched back to an active state, it reads the saved context and restores the platform to its original state prior to entering the inactive state. In one embodiment of the invention, the platform determines whether it should compress the saved context before storing it in a non-volatile memory based on the operating condition of the platform. This allows the platform to select the optimum method to allow faster resume time of the platform.

    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： 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.

    摘要翻译： 在一些实施例中，本发明涉及通过隔离与管理引擎（ME）UMA存储器相关联的错误，以故障恢复方式与系统恢复相关的系统和方法。 BIOS记录系统内存上发生的错误。 ME UMA对于主机操作系统是不可见的，因此不会在ME UMA范围内发生错误通知操作系统。 当ME UMA存在的存储器单元达到错误阈值时，ME UMA数据被迁移到先前保留的存储器备份区域，并向ME通知新的ME UMA位置。 在下一个维护周期，标记有故障的存储器进行更换。 实施例可以应用于利用AMT（主动管理技术）和ME UMA的ECC存储器保护的工作站。 描述和要求保护其他实施例。

    摘要： A processing system includes multiple processing units. After multiple event handlers have been dispatched to execute concurrently in different processing units of the processing system in a hidden execution mode, the processing system automatically determines whether the multiple event handlers successfully complete. If an event handler among the multiple dispatched event handlers fails, the processing system automatically dispatches another event handler to perform operations associated with the event handler that failed. In an embodiment, the hidden execution mode is a system management mode (SMM), and the multiple event handlers are dispatched in response to a system management interrupt (SMI) or a platform management interrupt (PMI). In an embodiment, the processing system may determine why the dispatched event handler failed, and may performing a corrective operation before dispatching another event handler to perform the operations associated with the event handler that failed. Other embodiments are described and claimed.
