Patent 7106600 was granted and assigned to Newisys on September, 2006 by the United States Patent and Trademark Office.
The present invention provides devices and techniques for replacing at least one processor in a multi-processor computer system with an interposer device that maintains at least some of the input/output (“I/O”) connectivity of the replaced processor or processors. Layers of the interposer device may be configured to match the corresponding layers of the motherboard to which the processors and interposer device are attached. According to some implementations of the invention, the power system of the motherboard is altered to allow a voltage regulator that powers a link between a processor and the interposer device to also power a link between the interposer device and an I/O device.
