Canon 5D Mark II with Firmware 2.0.8 and Magic Lantern Firmware 0.1.9

安裝方式（引用自 Calomile on DVXuser)：

There is a limit to which revision of ML your current firmware supports. I'd say to avoid problems use the most recent version you can find on the site for your specific firmware, otherwise you might encounter problems (that latter MLs have fixed)
ML is written to the RAM, it does not flash firmware permanently. To remove it all you have to do is power your camera off then boot it back up.
I have used ML many times and I have not encountered any problems, nor have many other people. As long as you are sensible and follow instructions properly and use a stable, tested release (not bleeding edge nightlys) then you shouldn't encounter any problems.
Instructions can be found on the front page of the wiki (http://magiclantern.wikia.com/wiki/M..._Firmware_Wiki) in the vimeo video. It's fairly simple, however, just download the firmware files (either from the wiki or the google groups pages) extract the files somewhere on your hard drive, then copy them onto the root directory of your compact flash card. Then, boot up your camera and select firmware upgrade, it should register that the ML firmware is on the card, then begin the process of writing ML to the camera's RAM. After a few seconds the camera will become operational again and you'll be running magic lantern.
