An E2 box is an Enigma 2 box, there are many makes of boxes like VU, miraclebox, gigablue for example.
Basically they can all run the same image, in your case Vix, regardless of who made the box.
So they all look the same from a menu point of view.
There aren't many guides about as you can do it so many different ways with lots of different devices.
If I was in your position I would look at maybe loading something like the Xsream plugin to your box
then loading the config file that goes with it.
They ftp to the box in a very similar way to adding a line to your box.
