HaloMods "Classic" Read-only Archive

I know this is like THE BIGGEST NEWBIE QUESTION EVER but how do I mod my xbox, what stuff do I need, or if you could point me toward a tutorial that would be greatly appreciated to

i dont know much about modding the Xbox, but i do know these things:

1 shrink your avatar, its far too big

2 you need a mod chip

3 thats all i really know.

I don't have an XBox but I believe http://llama.com has some good links, also GOOGLE is a good source of knowledge.
