I had my SP6 in storage for a month and when I booted it up, the screen was in System Mode. At the bottom of the page it reads "ENTER: Run SP6." So I hit enter, it looks like it's loading and then goes back to the System Mode page, and I can't get the thing to do anything else.  Any ideas (besides beating it with a hammer)?
