摘要:
A BIOS includes a core and multiple modules. The modules include both those that are platform specific and those that are not platform specific. Each module has a standard interface that allows the core (or other module) to call the module. A platform vendor constructs a BIOS by selecting modules from one or more vendors, which when executed can select modules that are suitable for the platform the BIOS resides in.

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.

An embodiment of the present invention is a system and method relating to seamlessly enable enhanced management and scripting of a computer system and its add-in devices. In at least one embodiment, the present invention enables a system administrator or integrator to script a common configuration for multiple devices and then automatically configure the devices using the script. The language construct and central data repository for configuration settings are extended to comprehend a scripting language. A script is read by a script engine during either pre-boot or runtime. The script engine searches a keyword database on the central data repository to determine requested configuration settings. A data offset is corresponding to a specific op-code is used to determine where configuration settings are located, for modification.

In one embodiment, a digitally signed image is embodied in a memory component such as a non-volatile memory. The digitally signed image comprises a post-relocation image and a digital signature. The post-relocation image is an image of a software module altered by a symmetrical relocation function by loading of the image into the memory component. The digital signature is based on the image so that it can be used to analyze data integrity.

An embodiment of the present invention relates generally to computer configuration and, more specifically, to a system and method to seamlessly determine the component configurations of a series of heterogeneous platforms and enable their respective component configurations to be intelligently migrated from one platform to another. In some embodiments, the invention involves generating configuration binaries for a plurality of target platforms. The configuration binaries are used with tools to create configuration directives for the target machines. In at least one embodiment, the configuration directives are sent to the target platforms in a scripting language. In some embodiments, the scripts are automatically generated by a tool using the configuration binaries for various platforms and policy guidance to determine which settings should be set on or off. Other embodiments are described and claimed.
摘要:
A method for restriping a striped disk array in a computer system without requiring the removal of the system from normal operation provides an efficient method to expand the disk array and incorporate the new storage into the striping scheme. When the operating system is not requesting access to the hard disk subsystem, the data is repositioned. The data on the array need not be backed-up onto alternate media before the array is expanded. Once new storage space is installed, the data is repositioned from disk to disk under the control of a disk controller until a stripe of the new array is expanded. Pointers stored in non-volatile memory maintain the location of the next free location and the next data block to be repositioned. The pointers are also used by the disk controller to locate the files during the array expansion process. The process is repeated until all of the data is relocated in the expanded array. After the relocation is complete, empty storage at the end of each disk remains. Once a new driver is installed to properly report the new volume to the operating system, the controller reports this new space as a separate volume of available memory storage to the operating system.

A method for updating firmware. The method includes providing replaceable information in a non-modifiable storage and replacement information in a modifiable storage or a removable storage and providing a replacement indicator. The replacement information is accessed instead of the replaceable information based upon the replacement indicator.
