I followed the wiki instructions here and it mentions credit to fanoush. I chose those instructions because Penguinbait's post mentioned this:

"install-tools will not be updated to support 43-7"

I didn't want to risk using it even though he said it should support 43-7 "in theory".

Now that I am booting and using the internal card are the files still compressed? I have plenty of room to install programs so that is not a concern. Maybe I should just use my external card for media. I am a little confused about the compression issue.
