Abstract
A data processing system has one or more portions which are present or absent. The variant of the data processing system is automatically determined by means of an infra-red switch whose beam is broken when the one or more portions are absent and not being detected when said one or more portions are present and is not broken when the one or more portions are present. From the output of the infra-red switch, the variant of the data processing system is determined. The variant information is then stored in the data processing system.
