@coffee - I ran my OS from SD in my 800 and 810, I run another embedded device's OS from a card. For my needs/wants it suits me well; I'd rather burn through some SD cards than the NAND. I know it's a myth blah blah write cycles write cycles etc....I just like it that way Anyone have this working with multiboot yet? Can you share your .item substance I've not had a lot of time to muck with it and have failed getting it to boot a few times. Thanks!
