摘要： Apparatus for providing electrical power to a processor (CPU) within a computing system includes a fixed-voltage power supply and a programmable power supply. When the computing system is turned on, a switching circuit determines whether the processor is a unified voltage plane type, having a first particular pin electrically floating, or a split voltage plane type, having this pin grounded. In either case, the output of the programmable power supply is applied to the pins associated with the core voltage plane of a split voltage plane type. If the processor is a unified voltage plane type, the switching circuit applies the output of the programmable power supply to the pins associated with the I/O voltage plane of a split voltage plane type. If it is of a split voltage plane type, the switching circuit applies the output of the fixed-voltage power supply to an I/O voltage plane of the processor, with the programmable power supply being first set to generate a voltage determined by whether a second grounded pin is present in the processor. Then, an instruction in an initialization program causes the processor having a split voltage plane to transmit an identification code, which is used to determine a final level of the programmable power supply voltage.

摘要： Apparatus for monitoring fan speeds within a computing system includes a tachometer turning with the fan, providing a tachometer signal including a number of pulses during each revolution of the fan. This tachometer signal is provided as an input to a signal generator in the form of a flip-flop, which generates a square-wave signal having transitions between high and low levels corresponding to tachometer signal pulses. The square-wave signals are provided as inputs to separate input ports of a microprocessor. These input ports are sequentially sampled at a rate providing at least two samples per period of the fastest square-wave signal, so that transitions of each square wave signal during a predetermined time interval can be detected and counted. For each input port, the number of counted transitions is compared to a stored acceptable value to establish whether the fan is operating in an acceptable speed range.

摘要： A computer system includes a system bus, peripheral devices, bus control logic having bus control lines for bus master operation, and an allocation control circuit. The allocation control circuit is connected to at least one of the bus control lines and at least two of the peripheral devices. The connected bus control line is coupled to one of the connected peripheral devices by the allocation unit so that the one connected peripheral device can operate as a bus master on the system bus. In a preferred embodiment, the allocation control circuit includes switches that are controlled by the system software. Also provided is a method of allocating bus master control lines to peripheral devices. According to the method, the bus master control lines and the peripheral devices are connected to an allocation unit. It is determined which peripheral devices to connect to which bus master control lines, and the allocation unit is directed to couple each bus master control line to one of the peripheral devices so that the selected peripheral devices can operate as bus masters. In a preferred method, the determination is based on user preferences and/or system-detected peripheral devices, and the system software controls the allocation unit.
