    摘要: A method and apparatus for accessing pages in physical memory, where the physical memory is described. The present invention provides a paged memory system having multiple page sizes. Pages of a first size are accessed via a page directory entry and a corresponding page table entry. The page directory entry stores a base physical address for a corresponding page table and control bits indicating permissions. The page table entry stores a base physical address of the page in memory. In one embodiment, the page table entry inherits permissions from the page directory entry. Pages of a second size are accessed via a page directory entry that stores a base physical address of the page and control bits indicating permissions associated with the page. In another embodiment, entries to the page directory table and the page table are 4-bytes in size and provide paging for memory up to 1.1 Terabytes in size.

    摘要: The present invention relates to a computer system in which linear memory attributes are specified. Physical memory attributes may also be specified in physical attribute registers. A memory attribute palette (MAP) receives index signals and selects linear memory attributes in response to the index signals. An effective memory attribute selector receives selected linear memory attribute signals and, if present, the physical memory attribute signals and, in response thereto, selects effective memory attribute signals to present an effective memory attribute. In a preferred embodiment, the linear memory attributes may be programmably written into one or more registers, thereby allowing a program or OS flexibility in the choice of memory attributes, including memory attributes not currently used. The invention allows a program to apply a memory attribute of choice to a particular section of memory, thereby allowing the computer system to provide higher performance.

    摘要: Embodiments of the invention are directed towards logic and/or modules stored in processor secure storage to determine whether a first platform firmware image (e.g., basic input/output system (BIOS), device read-only memory (ROM), manageability engine firmware) loaded onto a processor cache is valid. The processor executes the first platform firmware image if it is determined to be valid. If the first platform image is determined to be invalid, a second platform firmware image is located. If this platform firmware image is determined to be valid, the processor will execute said second platform image.In some embodiments of the invention, the determination of whether the first platform firmware image is valid is based, at least in part, on verification of a digital signature associated with the first platform firmware image. The digital signature may be created, for example, from a private key, wherein the digital signature is verified via a public key.

    摘要: Technologies for verifying hardware components of a computing device include retrieving platform identification data of the computing device, wherein the platform identification data is indicative of one or more reference hardware components of the computing device, accessing hardware component identification data from one or more dual-headed identification devices of the computing device, and comparing the platform identification data to the hardware component identification data to determine whether a hardware component of the computing device has been modified. Each of the one or more dual-headed identification devices is secured to a corresponding hardware component of the computing device, includes identification data indicative of an identity of the corresponding hardware component of the computing device, and is capable of wired and wireless communication.
