  • Patent number: 8301858
    Abstract: A control device is connected to a processor, a memory module, and a specification information storage memory for storing specification information indicating specifications of the memory module. The control device includes: a readout unit that reads the specification information from the specification information storage memory when power is turned on to the control device; a storage unit that stores the specification information read from the specification information storage memory; and a transfer unit that receives a specification information read instruction from the processor, and that transfers the specification information stored in the storage unit to the processor.

  • Patent number: 7631224
    Abstract: To completely perform a memory data collecting process by a panic dump in the event of failure, in the configuration information about main memory 5 announced to an operating system by boot firmware, different areas (first main memory area and second main memory area) are set between activation of an operating system in a system operation mode and activation of an operating system in a dump operation mode. In the event of failure, activation is performed in the dump operation mode and a dumping process is performed with memory information in the event of failure maintained.

  • Patent number: 7434042
    Abstract: A data processing system comprised of multiplexed boot devices storing operating systems so that when a device of a master system cannot be used for startup, a device of a slave system is forcibly switched to for startup, wherein a memory stores boot firmware environment variable area including first variable data including device setting data of boot candidates, second variable data including index data designating a boot device based on that device setting data, and third variable data in which a binary value indicating if multiplexing is “valid” or not is set and wherein boot firmware decides on a boot device based on the settings of the environment variable areas and starts up the operating system stored in that boot device to start up the system.

  • Patent number: 7302559
    Abstract: A memory dump program boot method includes the steps of defining, in non-volatile variables that are managed by a boot firmware of a computer system, boot information of a plurality of stand-alone dump programs that are installed in the computer system, and a table variable indicating a corresponding relationship of the plurality of stand-alone dump programs and a plurality of operating systems, specifying the boot information of a corresponding one of the plurality of stand-alone dump programs from the table variables when the boot firmware boots an arbitrary one of the plurality of operating systems, and writing information indicating the specified boot information in the non-volatile variables that are referred to when executing a stand-alone dump, and booting the corresponding one of the plurality of stand-alone dump programs when a booting of the stand-alone dump is instructed, by checking existence of variables that are referred to when executing the stand-alone dump and referring to information of the
