K-x iso

Hi, i've entered this forum because bought a pentax K-x second hand to start my adventure in DSLR. Despite pleased with the machine overall, after some use found out that was unable to set iso under 400. Went to the manual and in the menu put the iso to expand and got the possibility to go down to 200 iso. But it should be 100!?! I'm looking in the menus for what i'm doing wrong but not finding it. Someone can help?
Glad to be here. Best regards from Ribatejo in Portugal.

Turn off highlight corrections and you'll be able to select ISO 100.

Yes turn off highlight correction. The camera firmware reserves a stop at the low and high end of the ISO to provide for highlight correction in case there is accidental over/underexposure from the shot.
