thanks fanoush. Where I'm at now is I've got 2007HE on internal flash, 2006 on MMC and a 500MB vfat partition. What I'd like to try now, is have both OSes on MMC.

So I'm still confused whether to use 2 smaller ext2 partitions and a large vfat that both OSes can share, or 2 equal sized ext2 partitions and no vfat? cant i just SCP\SFTP any files I want onto an ext2 partition? Can applications be installed on vfat, and if so, why are people making 1.5GB ext2 partitions? I'm stuck on this concept. Why not just make an ext2 large enough to hold the OS uncompressed and make the rest vfat?

cheers.
