And here you go!
I coded an "Installer" for MagicLantern Firmware.
As usual (for my programs) it's a one click, no hassles procedure.
You can download it from here: http://goo.gl/X1MO7
Please let me know if you have suggestions, improvements, ideas..
1) Canon 550D / T2i updated to 1.0.9 fw.
2) an SDCARD formatted in camera or named "EOS_DIGITAL"
3) a card reader.
The installer can also be used to revert a bootable card to a normal
one (and vice versa).
Actually tested under Windows 7 64bit, Windows XP 32 bit.
It should work on any windows system and I think you need
Administrator's rights to run it. http://groups.google.com/group/ml-devel/browse_thread/thread/6e6a5fc0dcbfdee
After installation on the sdcard, all you have to do is to put the sdcard in your camera and do a "firmware update".
