I completed the tutorial 'Ndure Softmod Through Xboxhdm' and that works well. I want to set up XBMC to boot. What I've tried so far hasn't worked. I have a limited understanding about how the the softmod system works. The system now boots into unleasx by default. I can start XBMC through that.

Any help would be appreciated.

I figured it out. I had to copy the xbmc files into e:\dash.
