A tenant processor module is shown comprising a processor core, a plurality of strapping devices, and an input bus. The plurality of strapping devices are configured to indicate configuration information to a receiving circuit board assembly coupled to the processor module. The input bus, coupled to the processor core, receives the configuration information back from the circuit board assembly and provides them to the processor core at a first time. At a second time, the input bus receives operational data from the circuit board assembly and provides them to the processor core.

Method and apparatus for the automatic configuration of strapping options on a circuit board assembly

An apparatus includes a configuration selector that is selectively configurable to denote one of a plurality of operating modes for the apparatus, including a configuration mode. The apparatus further comprising a programmable multiplexer, a processor, a bus, and a storage medium having stored therein a basic input/output system (BIOS) equipped to operate in any one of the plurality of operating modes, including the configuration mode wherein the BIOS facilitates user programming of a plurality of operating parameters for the apparatus. The programmable multiplexer, responsive to the configuration selector, asserts a default bus/core ratio common to a plurality of processors and buses that can be employed to form the apparatus when the configuration selector is configured to denote the configuration mode of operation. The processor, coupled to the storage medium and the programmable multiplexer, operates to execute the BIOS, in a speed consistent with the asserted bus/core ratio. The bus, coupled to the programmable multiplexer, the processor and the storage medium, operates to provide instructions and data to the processor, including the BIOS, in a speed consistent with the asserted bus/core ratio.

An apparatus includes a storage medium having stored therein a segmented basic input/output system (BIOS) divided among a plurality of segments within the storage medium, and a processor operative to execute the segmented BIOS. In accordance with the teachings of the present invention, the BIOS includes a recovery function that is mode dependent in that while the apparatus is in an update mode the recovery function executes a full reflash of all relevant segments of the segmented BIOS, whereas while the apparatus is in a normal mode the recovery function executes a partial reflash of only identified corrupted BIOS segments.

A method and apparatus for testing a circuit board is disclosed. An apparatus having at least one clock source for providing a circuit board with a clock signal at a dynamically selected frequency, a storage medium storing programming instructions to control the clock source(s) to provide the clock signal at the dynamically selected frequency including a frequency that exceeds the specified operating range of frequencies for the circuit board, and for implementing parametric testing of the circuit board, and an execution unit coupled to the clock source and to the storage medium for executing the programming instructions. The programming instructions for implementing the parametric testing of the circuit board include instructions for testing the circuit board while the circuit board is supplied with the clock signal at the frequency that exceeds the operating frequency of the circuit board, thereby stressing the circuit board. The programming instructions cause the one or more clock sources to gradually increase the dynamically selected clock signal frequency to the frequency that exceeds the operating frequency of the circuit board.

A method and apparatus for automatically controlling integrated circuit supply voltages includes, according to one embodiment, a primary voltage regulator and a secondary voltage regulator. The primary voltage regulator supplies one of either a first voltage or a second voltage to a first plurality of inputs of an integrated circuit. The secondary voltage regulator conditionally supplies a third voltage to a second plurality of inputs of the integrated circuit in the event the primary voltage regulator supplies the first voltage, with the third voltage being substantially the same as the second voltage.
