Abstract
An apparatus and method for polling a plurality of components in a data processing system includes a sensor for determining when a request for power up has been made, a series of parallel circuits extending between a power sequence monitor/power control device and individual computer system components, a configuration bus connected between the system components and the power sequence monitor/power control device and comparison circuitry connected to the configuration bus for comparing a signal sent from the power sequence monitor/power control device, through the configuration bus and system components, and returned to the power sequence monitor/power control device, with a predetermined code for identifying and locating the system components.
