yes,yesy,yes, and don't know.

Another thing to watch out for, sometimes the size of the image is stored
persistantly in the
bootloader. This size is extracted when the .bin file is parsed via Ethernet
download.
If you are updating via Storage Card app this size location needs to be
updated also as it
is used by the bootloader to figure out how much memory to move from flash
to ram (assuming
we are executing from ram).
