I downloaded XBMC-CVS_2005-10-23-T3CH.rar from xbins and i was re-directed to a mirror site, The .xbe file is "rename_me.xbe" so it depends on what you put on bios set-up what to look for first when booting if you want to use it as your dashboard and the XBMC folder should be on the E: partition to work.
And Whoopin' is right that If you want to use as Apps it should be renamed as "default.xbe" otherwise it will not be included in the Programs Menu.
