Driver for the Hercules 3D Prophet 4000XT/4500 Kryo/Kryo II chipsets are given a number format like 1.0.7.103 however you need to drop the 1.x to get the actual version number which is 7.103. The reason most likely that the drivers was given these number was to get them to the 4 point version numbering system used by most software versioning systems (0.0.0.0).
