This is one I used, they have rearranged it since my last visit though:

This one has a little different selection:

Browsing through, neither have the addon showing where specific things are (what drive). If I can find it, I'll send you the link. If not, you should be able to configure it in the advanced tools from the server.
Just like installing XP or vista you can choose your drive you install on. I would have to break out the manual again, but I do believe I read somewhere that it's best to only have one drive in for install, and add the rest after the install of the OS.
