Abstract: An invention is disclosed for providing a signal indicating whether a processor is installed and providing improved voltage regulation. A contact is selected and isolated from an array of ground contacts and is further coupled with circuit for generating an INSTALL signal. A capacitor and pull up resistor coupled to a supply voltage, ground and the isolated contact form a signal line at a common node such that a circuit to ground is completed through the processor and the isolated contact when the processor is plugged in and a direct signal indication of the presence or absence of the processor is provided. Voltage sense lines of a Voltage Regulation Module (VRM) are coupled directly to processor contacts isolated from an existing voltage supply contacts coupled to the supply plane of a supply voltage within the circuit board providing improved regulation without adversely affecting power supply current capacity considerations.
