Glad this works for your shooting.
Unfortunately for me, chasing a toddler around a window-lit room I need to deal with light changing 3 stops in about a second of panning. This takes a lot more than a second to adjust for:
1. Take camera from eye because you can't see the ISO selection through the viewfinder, you must look at the rear LCD,
2. press Fn,
3. Press right arrow to select the ISO menu,
4. Press up or down arrows depending on the desired ISO,
5. Bring camera back to eye and lightly tap shutter button or OK to have the camera select the ISO you left selected in the ISO menu,
6. Hope your subject didn't move while you were doing all this and recompose the shot, and
7. Repeat 1 to 6 every time the little bugger changes direction!
Eventually, step 8 is to throw your hands up in frustration and buy a flash. This is what I did!

I'm using firmware 1.02 as well. No idea why you would see a different behaviour than what seems to be all the other K100D owners posting here.
Can you confirm that you are able to maintain Auto ISO with either a + or - EV value dialed-in? If you have a scene composed using 0 EV and Auto ISO is selecting something like 800 or higher and you then adjust EV up or down 0.3 (for example), does your K100D stay on 800 or does it go to 200?
