  • Patent number: 7577831
    Abstract: A method for relocating system management interface code in an information handling system which includes extracting a relocation table from the system management interface code, inserting a relocation identifier in each entry of the system management interface code having an address, searching the system management code for the relocation identifier during execution of the information handling system, and inserting an address based upon a relocation address for each entry in the system management interface code having a relocation identifier.

  • Patent number: 7457945
    Abstract: A system and method is disclosed for providing a firmware update to a device of a computer system in which a firmware update application and a firmware image are provided to a computer system. Verification steps are performed to insure that both the firmware update application and the user are authorized to perform the firmware update process. If the verification steps indicate that both the firmware update application and the user are authorized, the computer system is reset. During the boot process, the presence of the firmware update is recognized and the firmware update application is initiated, resulting in an update of the firmware of the device.

  • Patent number: 6192471
    Abstract: A system which builds an operating system-independent environment for executing utility programs is created by establishing a virtual drive that resides on a physical disk drive within the native file system of a native operating system. A virtual drive is a set of files on a physical disk drive that is configured to emulate a physical disk drive. The virtual drive can be deleted by a computer user and similarly can be re-established by the computer user. The virtual drive is bootable and activates an operating system that makes all system resources accessible to the utility programs and also allows the computer user to use the disk space that is allocated for the virtual drive, if desired.

  • Patent number: 5598577
    Abstract: A computer system in which the system software (while running as an overhead process which is not directly under control of the user) queries a disk drive to determine its model. The system software checks the corresponding response string with reference to a table of recognized model strings (in encrypted format). If the drive's response string is recognized in this table, then the drive parameters can be set appropriately. If not, then this portion of the system software will not set the drive parameters; instead, the normal manual setup procedure can be used.

  • Patent number: 5535371
    Abstract: A portable computer system wherein the printer port can be used, at the user's option, not only for connection to a printer, but also for connection to an external floppy disk drive. If the BIOS determines that there is an external floppy drive attached, the BIOS disables the normal operation of the parallel port in order to allow the external floppy to operate.

  • Patent number: 5471674
    Abstract: A portable computer system with a special connector, on the motherboard, into which a field-installable boot card can be inserted. The special motherboard connector is wired so that the operator, by setting connections on the field-installable boot card, can bypass the boot memory on the motherboard and force the computer to boot from the memory on the boot card. This permits a technician, in the field, to temporarily override the internal nonvolatile memory which holds the basic system software. This permits recovery of a system in which the basic system software has been corrupted. Preferably the motherboard boot memory is a flash EPROM, and can be rewritten, by setting appropriate jumpers on the boot card, after the computer has booted from the boot card. The motherboard connector is preferably located on the motherboard, and is accessible through a removable cover. This connector can also preferably be used for temporary attachment of a diagnostic display card.

  • Patent number: 5313626
    Abstract: A disk drive array with a controller which provides: dynamic remapping for grown defects in the disk drives, multi-thread request processing with a variable number of forkings, defect tracking with both logical and physical lists, guarded writes of less than a full stripe optimized by selectably using the redundancy to limit the number of sectors involved, association of multiple operations with a single disk request in order to facilitate error handling, use of an access hiatus as indication of further opportunity to rebuild data in background, and scatter/scatter (bidirectional scatter/gather) operations.
