Need Help With Using IDE 3

I have the setup listed in my sig. My questions is how do I install a regular hard drive, not raid, on IDE 3? What steps would I take? The manuel doesn't show how to. I currently have a 120gb hd that I want to install on this channel, but it is not reconize by windows. The drive is working though case I hear & feel it running. Thanks in advance for helping, because it is really needed.
