How do I install the operating system to an external hard drive? Can I use "SYS A:" ? Just kidding, only half of you knew what I was talking about anyway. The old half. <g> Seriously though, when I run the install CD, will it prompt me for the location? Or...what? Thanks!

UPDATE: Found this site http://www.ngine.de/index.jsp?pageid=4176 but I really didn't think this was going to be a big deal. I'm trying to reinstall someone's OS onto their hard drive for them. I bought a IDE/USB kit that lets me use their internal drive like an external one with my laptop, but now it looks like I've got to jump through serious hoops to get his XP loaded. If I had known this, I woud have just ripped apart my PC and done it from there. Sometimes I think MS totally sucks.
