How can I save camera settings to survive power cycle?

How can I save settings applied in the Webinterface, e.h. H-Flip=On & resolution=UXGA, so that they are restored on power loss?
(If power fails and comes back, I’d like to have my settings to be the same than before the power loss).
I can’t find a save button. Is there a way to hard code my own “defaults” in the script files, if yes, where?
