    摘要: In some embodiments a Trusted Platform Module (TPM) manages a first flag that identifies whether a secure environment has ever been established. A chipset manages a second flag that identifies that there might have been secrets in memory and a reset or power failure occurred. At least one processor and/or the chipset lock, maintain a lock, and/or unlock a memory in response to the second flag. Other embodiments are described and claimed.

    摘要: Disclosed is a method, apparatus, and system in which a basic input/output BIOS is run and a non-volatile memory coupled to the BIOS is read. The BIOS determines if legacy partition address data is not present for a disk partition identified in the non-volatile memory, and if legacy partition address data is not present for the disk partition, legacy partition address data may be obtained by a legacy OPROM. The disk drive may then be updated with the legacy partition address data.

    摘要: A multiprocessor computer system determines that the hard reset designated BSP has failed by examining its status bits. The designated BSP then selects a processor from among the APs that will take the place of the designated BSP. The selection is accomplished by, successively for every AP indicated to be good by examining its corresponding status flag, determining whether the AP is present, starting up the AP if it is present, determining whether the AP has passed its BIST, and selecting the AP to take the place of the designated BSP if the AP has passed its BIST. The BSP then designates the selected AP as the BSP instead of itself. The bootstrap indicator bit of the selected AP is set to indicate that the AP is the BSP. The bootstrap indicator bit of the designated BSP is cleared. The computer system then undergoes a soft reset which causes the selected AP to become the BSP and begin running the BIOS code from the reset vector.

    摘要: A method of testing at least a selected portion of system memory for a microprocessor system is disclosed, the microprocessor system having burst mode capability to transfer data values between the microprocessor and the system memory via a system bus. The method includes the steps of: writing at least a selected portion of system memory with a predetermined test pattern using the burst mode capability of the microprocessor system; reading back values from the at least a selected portion of system memory using the burst mode capability of the microprocessor system; and comparing the values read from the at least a selected portion of system memory with the predetermined test pattern written.

    摘要: A solution is presented to securing endpoints without the need for a separate bus or communication path. The solution allows for controlling access to endpoints by utilizing a management protocol by overlapping with existing interconnect communication paths in a packet format and utilizing a PCI address BDF (Bus number, Device number, and Function number) for verification.
