I already cloned OS on 2 SD cards, and they have different contents, I would like to have options to choose booting, rather than physically swap them. Would edit the bootmenu.conf work?
If so, please spoon feed with instructions, thanks.
I want to do the same to N810, are they, 1) internal flash, 256 MB 2) internal card, 2G (mmcblk0) 3) external card, SD (mmcblk1)
not quite sure 'how to approach it though, in particular to avoid re-flash if possible as i have accumulated quite some progs by now and dont quite trust 'restore'.
