    摘要： Faults in a computer system having circuits are managed by fault detectors connected to detect fault states of respective circuits. A fault manager associates the fault states with the respective circuits. The fault manager includes a system manager connected to identify which of the circuits is causing faulty operation in the computer system. The fault detectors associated with the respective circuits are configured to detect faulty operation of and to generate fault state information for the respective circuits. A central manager is connected to accumulate fault state information from the fault detectors. One of the circuits includes a bus, and the fault state includes a bus error condition. The bus is connected to multiple devices, and the fault manager identifies which of the multiple devices causes the bus error condition. One of the circuits includes multiple modules, and the fault manager identifies fault states of the multiple modules. The modules include state machines. One of the circuits includes an internal clock, and the fault state of the circuit includes the internal clock not functioning properly. One of the circuits includes a temperature sensor, and the fault state of the circuit includes a high temperature condition detected by the temperature sensor.

    摘要： A computer system utilizing multiple processes includes a semaphore for controlling exclusive access of a single process to a selected resource. The semaphore is implemented in the system input/output and controlled, at least in part, by an application specific integrated circuit (ASIC). When a process is attempting to acquire an I/O resource, a read is sent to the semaphore. If the resource is available the semaphore will have a first value, and the semaphore will return that first value to the process indicating that the process has acquired the resource. The ASIC will then change the semaphore value to a second value. If the resource is not available the semaphore will have the second value, and the semaphore will return the second value to the process indicating that the resource is not available.

    摘要： Through a menu driven selection procedure, a user is given options for how a server should respond to an actuation of a power switch. In one option, the power switch is disabled to prevent accidental shut down of the power supply in response to power switch actuation. In another option, the shut down of the power supply follows soon after the expiration of a count down timer which is triggered by power switch actuation. A subsequent actuation of the power switch in this option aborts the count down. In yet another option, the shut down of the power supply follows soon after the completion of a graceful shut down of the server operating system which is triggered by power switch actuation. A subsequent actuation of the power switch in this option causes an immediate shut down of the power supply.

    摘要： A system management module (SMM) for a host server system includes a system management processor (SMP) connected to a system management local bus. The system management local bus connects to the system PCI bus through a system management central (SMC). The SMC includes the main arbitration unit for the PCI bus and also includes the arbiter for the system management local bus. The SMM includes a video controller and/or keyboard and mouse controller connected to the system management local bus to support remote consoling of the SMM. The video controller is further used for transmitting screen images to a remote computer system to facilitate system failure analysis. A plurality of system management remote units are provided for coupling to various components and busses within the host computer system. The system management remote units (SMR's) connect to the SMM via serial bus and permit the SMM to automatically monitor activities and operating conditions, including determining the source of interrupts on busses and detecting error conditions.

    摘要： A bus ring-back and voltage over-shoot reduction apparatus with capability for rendering an expansion slot of a computer system hot-pluggable, wherein a logic gate controls a switching element so that when the element is turned on, the input and output (I/O) nodes of the element are in a low ohmic conductive relationship. One of the I/O nodes is coupled to an expansion card whereas the other node is coupled to a bus to which the expansion slot is connected. The apparatus operates as a level shifter wherein the output node voltage follows the input node voltage until pinch-off such that the output voltage remains substantially stable thereafter. The apparatus also isolates the expansion card from the bus when the system is running or during the powering up of the card.
