Avalaunch gives you the advantage of booting other dashboards/apps using the quicklaunch feature. Can you boot into BSX using this as well? I tried putting the BSX files into a folder on C:\ (C:\BSX\)...but that gave me an error 21. I want to make sure putting the BSXdash.xbe on root c:\ will not interfere with any of the other dashboard XBE's on the C:\. If I screw this up I might not be able to FTP back in my XBOX. Does anybody know?

You can put it on the root of C and it won't mess up any other dash. Most bios will look for avadash.xbe first anyway. You could follow this and get it to boot from other than C

there is a boot thing that i use called X Selector and u can configure it to boot anywhere from 1 to 8 different dashboards.
