Some 6d user on the ML forum reports his camera comes complete with a "Factory Menu" I've never seen before, but it takes regular fw updates nevertheless - though reporting another version after installation: http://www.magiclantern.fm/forum/index.php?topic=15088.msg146677#msg146677

Has anybody ever seen this and knows how the menu is triggered (camera hardware or nvram flag)? And probably even how to get rid of it (or activate it :))?
