How to install Magic Lantern with Dual ISO on Canon 7D

You have to follow these steps in order to try the Audionut ML build and the dual iso module:

1. Download and process required firmware files
2. Enable bootflag on 7D using EOS Utility
3. Install Magic Lantern using EOScard.exe tool

Detailed instructions are available on the ML support board at http://www.magiclantern.fm/forum/index.php?topic=3974.msg62242#msg62242

Dual ISO dynamic range improvement is explained in more detail at http://www.magiclantern.fm/forum/index.php?topic=7139.0

Status Before g3gg0's hack

Thanks to an anonymous donor we have a test 7D body and can produce a firmware dump from it.

• Apply this bspatch to the 7D 1.1.0 firmware (instructions and details) to generate a dumper firmware with md5sum f9d720f38c7991f9526d4b34e21c7d7c. Follow the normal "Update Firmware" procedure to write out a ROM0.bin file with the memory starting at 0xFF00_0000. The entry point is at 0xFF01_0000. (Trammel)

• See 7d 1.2.3 dumper (Indy)

Anyone can edit this page if you get bored. 

Using cache injection attack, it was possible to boot into canon firmware with ML loading in background.
