canon rebel uses DOS.

Possibly only as a bootloader or datashifter.

i find it interesting and hard to understand why so many operating systems must go into one little devise.

when i learned that DOS was being used on digital cameras a few months ago, i started trying to figure out the reason for this and came up with one good guess. this guess is because of the movies they make and the little microphones that record the sound as well as the image. i learned on the gimpi list that avi was a microsoft video file and this is what my little canon gives me when i make movies with it. my guess was that DOS was being used so that the WAV files could be produced more easily for the movies.

all of these guesses were made by someone who cannot read about hardware without falling fast to sleep and who did not search the web very much as well. and the fact that i was making and editing movies with my camera at the time surely had some effect on this guess.

however, what do you think? is it because of sound files? gap can only use WAV when encoding video, is this a fact about video files, that they only use WAV? and do you think this would influence camera design?
