Hey dude,
  When it comes to soft mods I reccomend going with Ltools. It's an amazing utility which makes modding your xbox so incredibly easy. Compatible with PAL and NTSC Xbox consoles. Or if you really need a hand visit our Store at
www.smdepot.net and we'll be happy to do it for you. Unfortunately I don't currently have a comprehensive tut. for Pal Xbox's, but it's in the works, like so many other things. Check out
www.xbox-scene.com for tonz and tonz of tutorials about everything Xbox. Sorry for the delayed response btw.
