ISO and E-PM2

I am sure this has been asked before but I can't find it (Google fu must be weak today), I  bought an E-PM2 and ISO goes from 200 to what seems like forever, but I keep seeing where its listed as starting at 100 in the specs and was wondering is there something locked that I am not seeing?  Firmware upgrade eliminated it?  I really like lower ISO's sometimes and would like to be able to access it if it doesn't reduce IQ.

The spec sheet for this camera on the manufacturer's website specifies a starting point of ISO 200. If you're seeing something else on a spec sheet on a different website, well, best to get it straight from the horse's mouth.

ISO 100 on the few current Olympus cameras that offer it is not particularly useful. 200 is the base ISO of these sensors. On those cameras that offer 100 it's simply capturing an image at ISO 200 and brightening it by one stop, which means you end up with one stop less dynamic range-- usually a heavy price to pay for slightly less noise.
