Sorry but what jedi pointed is just a tutorial for booting meego on EMMC but it will not dual boot maemo as it will overwrite maemo's kernel.


What I mean was you need to download the uboot source code, modify it to use another partition for meego(default is /dev/mmcblk1) recompile it and append it to a maemo kernel.

Instructions for compiling uboot and integrating it to a kernel is here
https://elektranox.org/n900/kernel/uboot.html

But that doesn't cover up on modifying uboot. As for a tutorial I don't have any and I can't make one also as I have never tried compiling one its just I have already looked up the sources of uboot so I know what I'm talking

BTW I also have read sometime ago it is also possible to modify uboot's path by creating a little fat partition on MMC and putting a file which I forgot the name (*flags) although I dont think its an option to you ask you dont have memory card as you said.
