Abstract: Method and apparatus for selectively overriding a prepackaged power management driver of a portable personal computer so that data transmitted to the CPIU of the computer by a device, such as a “real time” serial communicators device connected thereto, is not lost during the CPUs latency “wake up” period following a CPU power-down operation. An override system stored in memory comprises an override flag which may be set or cleared by a user or the computer. If the override flag is set, then the power management system is prevented from reducing power to the CPU so that the occurrence of a CPU latency period and thus potential for loss of data is avoided.

Abstract: A method of installing software on and/or testing a computer system includes reading a plurality of component descriptors from a computer readable file, each component descriptor describing a respective component of the computer system, reading a plurality of steps from a database, each step being associated with a component descriptor and including a respective sequence number, and sequencing the plurality of steps in a predetermined order according to the sequence numbers to provide a step sequence including commands for installing software on and/or testing the computer system. The method further includes determining for each step read from the database, from data associated with that step in the database, if that step is incompatible with the presence in the computer system of a component other than that corresponding to the component descriptor associated with the step, and if so, discarding or not discarding the step according to further data associated with that step in the database.

Abstract: A variable area heat sink has a first heat sink area and a second heat sink area. A bridge is connected to the first heat sink area and includes a bi-metallic portion operable to connect and disconnect with the second heat sink area in response to a temperature change in the bridge which is sufficient to distort the bi-metallic portion from a first shape to a second shape. The first heat sink area may be installed in a computer chassis adjacent a first heat producing component. The second heat sink area may be installed in the chassis adjacent a second heat producing component. The combination of heat sink areas may be enlarged or reduced in size due to the coupling or uncoupling.

Abstract: A system and method for handling system management interrupts in a multi-processor computer is disclosed. When the computer enters system management mode, the method uses the registers of each processor to get currently executing opcode to determine what each processor was doing before the interrupt. The method may have to first translate address information to locate the actual physical location of the currently executing opcode. The registers are stored in memory and the contents of the registers can be used to determine if the current processor caused the system management interrupt. If so, then the method now knows which processor caused the interrupt and can handle the interrupt accordingly. If, however, the processor was not the one that caused the interrupt, or if another processor also caused an interrupt, the method then repeats the above steps for the next processor of the multiprocessor system.
