STKD-
First of all, thanks for the tutorial. I was able to get this working thanks to you, but I think a couple of things need clarification.
The exploit that I downloaded contained bert.xtf, ernie.xtf, and default.xbe. Applying these three files alone resulted in the xbox booting to a black screen with the xbox-linux webpage address in white text, nothing else (I posted about this a few pages back). According to the tutorial, it should have taken me to evo-x. I'm sure there are a lot of these exploit packs out there by now and I was simply using a different one than you did. Perhaps clarify a bit as to what exploit package you were using.
I used free-xevox which required me to bring over the 'Skin' folder. Since this is not possible, I renamed the Audio folder to 'Skin' and the subdirectory 'AmbientAudio' to 'PheoniX' and put the skin in there. Once I could boot the x-box to evo-x, I ftp'd in and created a new 'Audio' folder, and copied all of the contents from the (now named) 'Skin' folder (minus the skin) into the new Audio folder. (Renaming 'PheoniX' back to 'AmbientAudio', of course.)
Like I said, it's a great tutorial for the most part, and I certainly wouldn't have gotten it working without it. I just figured that if I had these problems, more than likely other people will run into them as well.
