    摘要： A multiprocessor computer includes a processor disabling scheme which disables a processor that has been designated to boot the computer but fails to boot the computer. For computers having voltage regulator modules (VRMs) to power each processor, a control device directs a VRM associated with the failed boot processor to cease supplying power in response to the processor's failure. For computers without VRMs, a transistor controls the delivery of power from the power supply to each respective processor. If a designated boot processor fails to boot the system, the control device turns off the appropriate transistor to disable the failed processor.

    摘要： The system and methods describe a computer system implementing an adjustable control signal path whose length may be precisely adjusted to control timing of a control signal that propagates along the path. One such adjustable signal path has two clusters of possible signal paths. Each of the signal paths in each cluster has a length, and the overall length of the control signal path may be adjusted by selectively implementing one signal path from each of the clusters by electrically connecting that path into the electrical circuit by the selective installation of zero ohm resistors. In this way, a system designer may design several possible signal path lengths on to a motherboard or printed circuit card, and implement the path length which provides the most precise signal timing adjustment.

    摘要： An apparatus supports the sharing of a resource among computer applications. The computer system has a processor which adapted for executing a first application in a first mode of operation and a second application in a second mode of operation. The computer system also has a communication port adapted to receive the resource. The communication port is normally allocated to receive accesses from the second application. The computer system also has a virtual port for emulating the communication port. The virtual port diverts accesses from the first application directed at the communication port and buffers the accesses in the virtual port. An arbitrator is connected to the processor, the communication port, and the virtual port. The arbitrator claims the communication port from the second application and forwards accesses received by the virtual port to the communication port if the first application is accessing the resource and if the communication port is idle. Further, the arbitrator reallocates the communication port back to the second application upon the termination of accesses to the resource by the first application.

    摘要： A computer system that provides for transparent plugging and unplugging of a keyboard independent of system operation. A virtual keyboard device communicates with the system keyboard controller when no keyboard is plugged. The virtual keyboard device provides appropriate responses to inquiries from the operating system during startup, allowing the system to boot without an actual keyboard being present. When a keyboard is plugged, its presence is detected and it is configured by a virtual keyboard controller. The newly configured keyboard is then coupled to the system keyboard controller. On unplug, the lack of a keyboard is detected by monitoring the power supply to the keyboard, whereupon the virtual keyboard is again coupled to the system keyboard controller.
