How to make PCH-IO visible ?

i have a gigabyte bios that i have modified to my liking but i can`t see the PCH-IO Configuration menu in the bios even though i made it visible with AMIBCP5.
from what i checked on the forum, it seems that you can make it visible by replacing it with another menu.
i would like to know how to do that, if someone is kind enough to explain.
