get all of them!
Make a folder on your pc named UixInstall (or something you'll remember).
Extract "01.03.05.user.interface.x.dash.rar" to it. there will be a readme a folder called "user.interface.x.dash" and an xbe named "uix.xbe".
Extract "Replacement.UIX.XBE.rar" to the same folder overwriting the existing one with the new one and rename to "evoxdash.xbe"
Extract "01.03.05.user.interface.x.dash.audio.and.fonts.rar". Place the extracted audio and fonts folders inside the "user.interface.x.dash" folder.
Now still inside the "user.interface.x.dash" folder browse to the "system" folder (\user.interface.x.dash\user.interface.x.dash\system) and open "uix.ini" with notepad.
here you need to set paths to your applications/emulators/games etc. You will see near the bottom something like this:
Path=apps is what the name of the folder on your xbox harddrive is called (could be different for you) Name=Applications is The title for it you will see in the dash. No need to set drive paths - UIX scans all drives for your set paths ie e:\games. f:\games etc.
hers what mine looks like:
Make your changes and save the file then Ftp all of that to the root of C drive (four files will fail to copy this is normal, and intentional) You should have just copied about 113 megs to you Cdrive.
Your Cdrive should look like this:
heres what it looks like installed alongside the original msdash on C
Note: for UIX make sure all yr actual apps/games/emus/dashes are in there own folders inside your set paths not in subfolders. all xbe's should be named default.xbe.
