this isnt really the place for this.
i do know of a forum that i used to frequent many years ago. infact you can search up my username there. its the same as this one. the original xbox was my specialty. i have done some pretty significant mods. i would highly recommend getting a mod chip though. just in case you mess up, you always have a way to recover. i have seen too many people do a soft mod and unlock there HDD leaving the xbox unusable. and had to throw out money to get a chip. so just do it anyways. it will save you trouble
