In a system including a processor and at least one connector for providing inputs to the processor, which one of a plurality of different types of peripherals is plugged into the connector is determined by sensing any change in the connection of a peripheral to said connector, upon initial start-up of the system and each time a change from not plugged in to plugged in is detected interrogating the peripheral to obtain its type and storing the type of peripheral which is plugged in.
