Yup as Pluto says, there's a lot of scripting and tweaking going on, so if you're not good at modding, what I suggest is, download any of chargen mod you think is most simple, and compare it's scripting changes to the original chargen of Morrowind. Best way to do it, at least was for me.
Good luck
thanks man, i got it to work, just tweaked some of the scripts in chargen revamped v.1.4 to start me out at sotha sil, dome of sotha sil, its part of a larger mod im working on in which member of the psijic order resurrect sotha sil (the player) as a cyborg (with a chance to become dunmer later in the game) because the nerevarine joined dagoth ur instead of stopping him. thats in a nutshell really though
