    摘要: A user specifies, in advance, the expansion devices which he/she does not want to remove among the expansion devices which are attachable/detachable with respect to the PC, and the specified expansion devices are excluded from a list displayed later for the user to select an expansion device to remove. Besides, whether to display expansion devices in the list is specified to an BIOS and the information referenced by the BIOS is stored in an NVRAM.

    摘要: A method for protecting a privilege level of a system management mode (SMM) of a computer system is disclosed. A SMM program is loaded into a special memory (SMRAM) area within a system memory of a computer. A first program, a second program, and a vector table are loaded into a general area of the system memory. Before the booting process of the computer has been completed, a reference hash value of the first program is determined by the SMM program, and the reference hash value is stored in the SMRAM area. A hash value of the first program is the computed by the SMM program. After the computer has been operating under an operating environment of an operating system, the computed hash value is compared to the reference hash value. When the computed hash value matches the reference hash value, the first program is called by the SMM program.

    摘要: A computer system apparatus and method therefor are described which are appropriately power-controllable corresponding to each usage-situation. The computer system includes a PC main body and a digitizer wherein the usage-situation of the system is detected. If one of the predetermined usage-situations, such that the digitizer is mainly employed, is adopted, a target power saving mode is determined corresponding to installation or non-installation of an AC adapter, remaining amount of a DC battery, data upload frequency from the digitizer, and other conditions. In addition, in the case that the PC main body is in a power saving mode, the PC main body returns to the normal mode if data upload from the digitizer is requested. After completing the upload, the main body returns to an appropriate power saving mode.

    摘要: An information processing system (IPS) including an external storage device having a drive control unit for performing reading/writing operations on a recording medium in response to a request from an operation system, in which the drive control unit transmits to the operation system a connection state response indicating that the external storage device is connected to the information processing system, when the drive control unit receives from the operation system a connection state request. The IPS includes: a power control unit for suspending a power supply to the drive control unit; a request substitutional receiving unit for receiving, in place of the drive control unit, the connection state request from the operation system when the power supply to the drive control unit is suspended; and a request substitutional replying unit for returning the connection state response indicating that the external storage device is connected to the information processing system.
