Reboot resets all configs

[kormi]

I tried to look for this one, but nobody else seems to have the same problem. I am probably not seeing something, but everytime I have to reboot my Raspberry (through pulling power from it), it seems to forget most of its configuration. The most annoying part is the video calibration, I have to adjust it quite a bit on my TV, and have to do it again and again after rebooting. Is there a way of telling the system to remember everything? Thanks...
