I am interested in Magic lantern

The firmware reisdes on the Card in the camera and operates from there

WHere are the images taken placed--on the same card?  If you load the firmware and then remove the card, I think the firmware does not work--is that correct.

Does this mean you need to place the firmware on each card you want to use OR does the camera  remember and allow one to simply put in a new card when the prior one is full

From reading the installation FAQ; It's correct that every card you want to use will need the firmware on.
Beyond that it seems the current version also permanently changes the camera's default firmware so that it won't work without an autoexe.bat file on a memory card, which implies that a camera that has had ML 2.3 installed will then only work with specially prepared cards.
This seems to me to be rather inconvenient and limiting compared to previous versions of ML. I'm not going to risk installing it until I've heard a lot of good reports about it and no bad experiences.

I wish Canon would wake up and offer similar features in an official firmware upgrade. I think many of us would be prepared to pay quite a worthwhile amount for such a product, but only Sony seem to have seen paid firmware upgrades as a good business model so far.

The installation procedure consists of two steps:

* Preparing the camera (once per camera).
* Preparing each card (once per card).

Preparing the camera just activates a hidden flag: when that flag is active, each time the camera boots it will check for a BOOTDISK flag in the CF; if that flag is found, then the camera will look for an AUTOEXEC.BIN file in the card, and execute it. Preparing a card means activating the BOOTDISK flag and copying the AUTOEXEC.BIN file.

So, back to your questions:

* A prepared card remains perfectly usable for any purpose; files are saved on the same card where ML resided, and can read using any CF reader, as if nothing had ever happened.

* If you prepare the camera, and activate the BOOTDISK, but fail the copy the AUTOEXEC.BIN file, then the camera will refuse to boot; however, using a non-prepared CF (no BOOTDISK flag activated) on a prepared camera is perfectly fine.

* Camera switches off each time the card door is opened, so you need to prepare each card you want to use.

Hope this helps.
