How do I gain root access to file locations such as usr/home... I have enabled advanced mode, and even followed the directions on mcales (or whatever the website is) to update to Firefox 3, but I found a desktop background I wanted to use, and I was supposed to just extract the files to usr/share...or a similar location, and, from the File Manager, when i try to type in usr/share...usr/home or anything like that, I get the little red circle with the horizontal white dash through it. Any help?
