  • Patent number: 6532499
    Abstract: A method for switching among a plurality of key functions allocated to a special key, whereby the occurrence of a phenomenon that is contrary to a user's intent can be prevented. When a key event detector 14 detects the depression of a special key, it sets a register 18 by which a request is asserted to output a make scan code that is supposed to be output when the special key is independently depressed and that is originally allocated for the special key. A key event analyzer 15 and a code generator 16 output a scan code to carry out a predetermined key function in response to the depression of a key. But if the register 18 is set when the special key is released, the key event analyzer 15 and the code generator 16 output the above described make scan code.

  • Patent number: 6526567
    Abstract: The invention relates to a method for executing, in a computer system 5, a device driver 10 which is used by a number of applications running on that system. A first 12 and second version 11 of the device driver are provided, with the first version being optimised and the second version containing debug code for providing trace information. Upon discovering a problem with the device driver, it is possible to selectively switch to the debug version of the code without any of the applications already using the device driver being aware of the switch. Having gathered the necessary trace data, it is then possible to transparently switch back to the optimised version. Conventionally, device drivers form part of the operating system within a computer and so are difficult to remove and re-load without taking the whole system down and re-booting.

  • Patent number: 6523125
    Abstract: To provide an information handling system and a method of controlling the same which allows the state of the system to be saved without destructing other user data on an external storage device. When a predetermined event occurs, the system saves hibernation information in a hibernation information storing area on a hard disk. A hibernation managing information storing area is provided in the outermost cylinder of the hard disk. A boot sector already exists in the outermost cylinder. Therefore, the hibernation managing information is written in the outermost cylinder after the boot sector has been sheltered to the hibernation information storing area. After such series of processes have been completed, the system shifts to a hibernation mode. On the other hand, when power feeding to the system is resumed, the hibernation information is read out to check whether or not the system was in the hibernation mode, etc.

  • Patent number: 6519669
    Abstract: The invention provides an apparatus and a method of hot docking/undocking a bus line and a peripheral device of a computer. The bus switch 60 connects and disconnects the bus lines 16a and 16b. The bus switch control circuit 61 generates on line 305-311 a bus switch control signal which responds to a turn around cycle from the signal on the bus line 16a and supplies it to the bus switch. The bus switch is operated to open/close in response to the bus switch control signal. Thus, the bus line 16a is in a turn around cycle in connecting/disconnecting the bus lines 16a and 16b so that the cycle operation of the bus is not affected by a noise accompanying opening/closure.

  • Patent number: 6513124
    Abstract: The number of executed instructions (Iu) in a user mode as one of performance indexes of a computer, and the total number of executed instructions (It) as one of power consumption indexes are used. These parameters have a relationship of E−It/Iu with energy index E. An operating speed (operating frequency) of CPU is increased or decreased so that a value of the performance index may be increased within a range of the power consumption index specified by a user, or a value of the energy index E may be decreased. By doing so, power management processing may be performed, which balances the power saving with the performance.

  • Patent number: 6496910
    Abstract: A method for loading instruction codes to a first memory and linking said instruction codes is proposed, whereby at least one instruction code has as parameter an address which during a loading step is not determined. This address-parametered instruction code has assigned thereto an address place. A relocation information is loaded which during a linking step effects that the address becomes determined using a starting address and a relative address offset. The then determined address is put at the address place. During the loading step, directly after loading each address-parametered instruction code with its address place, the relocation information is loaded and the address is determined in the linking step.

  • Patent number: 6477586
    Abstract: A multi-threaded, multi process distributed system including remote call procedure (RPC) messages. The threads in the distributed system are each associated with a queue. The RPC messages each include an identifier to identify the queue which is associated with the thread which has originated the RPC message, as well as an identifier indicating the connection over which the RPC message is communicated from one process to another. The connection over which RPC requests are forwarded in the distributed system is made between one process and another process. The RPC messages sent between processes utilise the same connection, independent of which thread in each process is sending or receiving the messages. RPC messages are forwarded through the distributed system and the connection and queue identifiers in the RPC messages are updated as the message is forwarded from process to process in the distributed system.
