If there's NO uSD, or the uSD doesn't contain a folder named 'boot' on the
first partition, with a file named 'uImage.bin', then Qi will boot from
NAND.  It's just if you WANT a dual-boot environment that currently Qi
doesn't let you do that simply.  As Andy noted in his response to that
post, however, he plans for Qi to support user selection of boot, it just
doesn't do it at this time.  Until it offers the ability to select, then
the present behavior (check for kernel on uSD, else use NAND) makes more
sense that always going to NAND and only NAND.
