Abstract: A method, system, apparatus, and computer-readable medium for updating the management information of a computer system are provided. According to one method, a system management information table is built during the execution of the computer system. The system management information table is built from a base set of management information and one or more updates to the base set of management information. The updates to the base set of management information may be stored a protected region of a non-volatile memory device. A utility program is provided for storing the updates to the management information in the non-volatile memory device.

Abstract: Methods, systems, and computer-readable media are provided for managing memory within a system management mode (“SMM”). According to the method, a memory management program is executed within the SMM. The memory management program is operative to maintain a singly linked list having one or more descriptors for identifying allocated regions of system management random access memory (“SMRAM”). In particular, each descriptor identifies a region of SMRAM that has been allocated by the memory management program by storing an indication of the base memory address of the allocated region, an indication of the ending memory address for the allocated region, and a pointer to the next descriptor.

Abstract: Methods, systems, and computer program products are provided for making PEI phase implementation independent from DXE phase implementation in a computer system implementing the Extensible Firmware Interface standard. For example, one embodiment of the present invention uses a hand-off block to make SMBASE initialization in PEI independent form SMBASE initialization in DXE. In another embodiment of the present invention, PEI phase is entered in order to resume from an S3 standby state.
