I want to dual-boot my 770. OS2006 on internal flash, OS2007HE on 1GB MMCMobile. (Who doesn't?)

Question 1: Is there a concise guide to doing this? The wiki guide doesn't mention OS2007HE compatibility.

Question 2: Do I have to partiton? Why not have one big partition? I realize that Windows PCs can't mount an ext2 partition (though there is a driver available), but all my PCs are Linux-based, so that's okay. I would want to partition for swap, though.

Thanks.
