Hello,
Nice to find all of you people here.
Thank you for this great tutorial.
I have installed successfully 2.3 to eMMC and configured Multiboot to boot from it.
But when I have my memory card inserted Multiboot tries to load from it Nitdroid and nothing happens.
What is the problem? Do I need to configure anything else to ingnore my memory card?

Thank you all for your great effort!
