I have been booting from my MMC on my 770 for a long time now. But the question arises for me now that I'm about to receive my N800 with its two card slots: Will I have the option to boot from either of the card slot locations, or am I restricted to the internal one? And carrying this query a bit further: can I boot from both? The basis of this last query is whether there is the possiblity of having separate operating systems employing different window mangagers, one on each of the memory cards and opting which one to load with a further hacked opening menu (similar to what is possible with Grub)?
