Rebooting XBMC to EvolutionX

This might seem a silly question but searching yielded nothing. If I had the box in front of me I'd be able to surely find it; I gave my buddy my old modded xbox, and he wants to try out the SNES emus on it, however, I have it setup to boot directly into XBMC, and I can't for the life of me recall how to get back to the evX dash. When he chooses reboot, it gives him the official dash, and I can't think of how else one would get to the other dash. Assistance would be greatly appreciated.
