The mods are right-modded even Zhaoliang´s didn´t work for you. Last posibility: ISA module (at your own risk, never done before!!) Yen
So I think a pilgrimage to Lourdes or Santiago could solve any of your own problems (eheheh I'm joking). Sincerely I don't know why you're experiencing so many problems. Only thing I can say to you is that same intel bioses on similar chipset and motherboards, work flawlessly, so I continue to keep up my theory, that is you have problems on your own pc (even if with loader vista is working for you) !!!
