The board I have has only 4GB of MMC on board which wasn't big enough for the later versions of the OS, but you could boot off of the SD instead if you held down a button on the board while powering it up.
There was a way to tweak it so you didn't have to hold the button down, but it was kinda involved IIRC so I never got around to it.
