K-x minimum ISO rating

This forum has been wonderful for me, answering the questions i couldn't really eke out from the manual. Only just last night, realised the reason I couldn't select Anti-shake from the menu was that i was leaving it on remote all the time. Doh. I took a few of detail in my room, had incredible clarity at 0.5 /sec exposure. Time to try raw files again, I bought Lightroom for that purpose but can't seem to get my head around. I'll keep plugging away at it
But there is one question I do have. My K-x has a minimum ISO rating of 200, my K200D had a min of 100. I have previously seen mentions of the K-x being used at 100 ISO on this forum, but a search is yielding me nothing. Is there a software upgrade for this, currently on v.1?

I have Ver 1.03 (the latest). The normal ISO for the K-x is 200-6400 (pg. 90 of English manual) but can be expanded to 100 - 12800. This should help too (this refers to pg. 91 of man., top of page, 3rd bullet point):

And make sure you disable dynamic range expansion (shadow/highlight correction, etc)
