With cable going active in our apartment today, I'll be able to set up our new cable modem. The self-install kit comes with a CD, but I'm assuming all it does is configure your network settings and install a Comcast-branded version of IE. I'm more than comfortable configuring my network settings, and I'd hate to install extra software I won't use/need. Can I set up the cable modem manually without the CD? What's the procedure?
