摘要： Methods of reliably allocating, writing, reading, de-allocating, re-allocating, and reclaiming space within a nonvolatile memory having a bifurcated storage architecture are described. Allocation, writing, reading, de-allocating, re-allocating, and reclamation are handled by a memory manager. The memory manager tracks the progress of each process during execution in order to detect whether a selected process was interrupted for purposes of recovery. The nonvolatile memory is recovered to a known state during initialization. Initialization includes the step of determining a recovery state from a recovery state lookup table. A selected recovery process is selected in accordance with the recovery state lookup table. A restart level for the selected process is determined from a corresponding restart state lookup table. The selected process is then restarted at the restart level. In one embodiment, a method of managing a nonvolatile memory includes the step of identifying an interrupted process from at least one of an allocation, a reclamation, a configuration header reclaim, and a re-allocation process initiated on the nonvolatile memory. A recovery process is selected for the interrupted process. An entry point into the recovery process is determined. The selected recovery process is then restarted at the entry point.

摘要： Methods of allocating, writing, reading, de-allocating, re-allocating, and reclaiming space within a nonvolatile memory having a bifurcated storage architecture are described. A method of reliably re-allocating a first object includes the step of storing a location of a first object in a first data structure. A location of the first data structure is stored in a second data structure. A duplicate of the first object is formed by initiating a copy of the first object. An erase of the first object is initiated. A write of a second object to the location of the first object is then initiated. The duplicate object is invalidated. The status of copying, erasing, and writing is tracked. The copy status, erase status, write status, and a restoration status are used to determine a recovery state upon initialization of the nonvolatile memory. The duplicate object is invalidated, if the writing status indicates that the writing of the second object has been completed. The first object is erased, if a restoration status indicates copying of the duplicate object was initiated but not completed. The erasing of the first object is completed, if the erase status indicates that erasure of the first object is not completed. A restoration of the duplicate object to the location of the first object is initiated, if the copying status indicates that copying of the first object was completed. The copying of the duplicate object is tracked as a restoration status.

摘要： Methods of allocating, writing, reading, de-allocating, re-allocating, and reclaiming space within a nonvolatile memory having a bifurcated storage architecture are described. A method of storing an object within a managed object space of the nonvolatile memory includes the step of determining an object class for the object. Objects of a first class are stored contiguously proceeding from a first end towards a second end of the managed object space to form a first class of space. Objects of a second class are stored contiguously proceeding from the second end towards the first end of managed object space to form a second class of space. A header identifying the object is stored at a bottom of the first class of space. The object is stored at a selected one of the bottom of the first class of space and a bottom of the second class of space in accordance with the object class.

摘要： A protected boot sequence in a computer system. A reset vector directs the system to a boot program including a protected program. This protected program verifies the integrity of the BIOS contents before branching to the BIOS for execution of normal bootstrap functions. The protected program can also lock down various blocks of bootstrap code to prevent them from being changed after a certain point in the boot sequence. The protected boot sequence can proceed in layers, with each layer providing some level of validation or security for succeeding layers.

摘要： A modular BIOS update mechanism provides a standardized method to update options ROMs and to provide video and processor microcode upgrades in a computer system without requiring a complete replacement of the system BIOS. The MBU mechanism provides several advantages. First, new features and BIOS bugs from earlier release may be delivered to an installed base of end-user systems even if direct OEM support cannot be identified. Also, BIOS components may be provided as a validated set of revisions. With resort to a validation matrix, BIOS updates may be managed easily. The modular BIOS update is particularly useful in systems having several independent BIOS's stored within unitary firmware.
