Pentax k-x - locked at ISO 400?

Hey gang, i tried searching for a full chart of how to change the minimum iso settings based on menu settings, but didnt find anything.

Im wondering why my camera has made ISO 400 made itself the minimum choice? It was ISO 200 but then i started messing around :P

Also, my high ISO pictures are really really grainy, what tools can fix this when shooting in RAW?

Two camera options can have an influence on the base ISO setting:
- Menu Capture 1 > D-range settings > Highlight Correction / Shadow Correction On/Off
- Menu C1 > 3: Expanded sensitivity > On/Off

Turn on expanded sensitivity, and turn off highlight correction and shadow correction, and you should see ISO 100-12800 as your ISO range.

Also it can be relataed to set ISO mode: AUTO/FIXED
1 Press the four-way controller in Capture mode. The [Sensitivity] screen appears.
2 Use the four-way controller
to select [AUTO Setting] or [Fixed Value].
The sensitivity range can be expanded to a range of ISO 100 to 12800 when
[3. Expanded Sensitivity] in the [A Custom Setting 1] menu (p.81) is set to [On].
