Abstract
Aspects for increasing control information from a single general purpose input/output (GPIO) mechanism are described. The aspects include establishing a plurality of voltage levels to indicate a plurality of states for association with installed options on a computer system planar. Further included is the determination of which of the installed options is present via the single GPIO. An analog-to-digital (A/D) converter is also included and converts a voltage level signal indicative of installed options on the computer system planar, while a resistor network is utilized to establish the plurality of voltage levels.
