摘要:
A method, apparatus and computer-usable medium are presented for loading firmware onto multiple processors. A firmware controller is coupled to multiple processors and a firmware memory. A service processor, by controlling the operation of the firmware controller, selects one or more of the multiple processors. Under the control of the service processor, the firmware controller sends firmware from the firmware memory to each of the selected processors, either sequentially or simultaneously. If one of the selected processors fails to fully execute the firmware from the firmware memory, the firmware controller notifies the service processor of that failure as well as the particular memory address in the firmware where the failure occurred.

A method, apparatus and computer-usable medium are presented for dynamically selecting a clock signal used by a peripheral device that is coupled to a motherboard. When the motherboard is powered off, a clock selector sends the peripheral device an internal clock signal from the peripheral device's own internal clock controller. When the motherboard powers up, the clock selector sends the peripheral device an external clock signal from the motherboard.

A method comprises providing a golden ROM unit comprising known good ROM code. The golden ROM is coupled to a ROM socket of a target system. The target system is booted, wherein booting comprises providing power to the target system and independently providing power to the ROM socket. The known good ROM code is loaded from the golden ROM to a system memory of the target system. Power is removed from the ROM socket and the golden ROM is decoupled from the ROM socket. A first subject ROM is coupled to the ROM socket. Power is provided to the ROM socket and the first subject ROM is programmed with the known good ROM code.

A method, system, and computer-usable medium for implementing a programmable DMA master with data checking utilizing a drone system controller. According to an embodiment of the present invention, a drone processor generates a collection of random data and stores a first and second copy of the collection of random data in a first and second memory location in a drone memory. The drone processor writes a third copy of the collection of random data in a processor memory. When the drone processor retrieves the third copy from the processor memory, the drone processor writes the third copy in the second memory location in the drone memory. When the drone processor compares the first copy with the third copy, the results of the compare is written in a status location within the drone processor.

An apparatus and a method for testing one or more processors. The apparatus and method provide a host computer that issues test case information. The test case information is translated from the architecture used by a host computer to the architecture required by the electronic components. The processors are then able to perform the test case.

A system and method of monitoring the communications of remote devices is described. The system includes a plurality of remote devices, where each remote device has one or more sensors and a communications transceiver. A control center, which includes a historical usage database reflecting historical usage patterns for each of the plurality of remote units, analyzes the communications for each of the plurality of remote devices against the historical usage patterns for that remote device to determine when that remote device is malfunctioning or approaching a usage threshold. The control center is then operable to take appropriate corrective action in response to the analysis.
