well, i have a question, just to make sure: are all those features listed on the "read me" file applyable to a590is, or that is just a general description of chdk firmware improvements available for other canon cameras?
also, i still didnt find on your "read me" file how to put that firmware (100e and 101b) into my a590is camera. i take it i have to go to one of those links you've posted there, right?
