O.K., I am a total luddite so I don't really understand what you are saying here. Not accusing you of poor communication at all, just asking if there is another to say this in such a way that someone whose only understanding of things electronic is how to use the on/off button ?
Ok, I'll try it once more :-) ... but really see also http://magiclantern.wikia.com/wiki/Unified/Install
To install ml on your camera two things need to be done, both are done once by installing the mini-ml firmware: set one flag in the camera and one on the cf/sd card. Then you just copy the ml files on this card, done. If you want to use another card, you have to set the flag on this card, too, by using a utility called "eoscard" and again copy the files.
If you have both flags set, there is only one catch (see red warning on the webpage): "Don't just delete the Magic Lantern files from the card! If you do, the camera will freeze at startup and you'll have to take the battery out." ... so each sd/cf card has to have *both* the flag and the files, or *neither* as a "clean" card.
