Looking for a HOW-TO to ftp install linux

I just downloaded Red Hat 6.2 using ftp. In spite of my cable modem it
still took a long time. I would like to ask about an ftp installation
because I've never done it that way and it sounds like it should be quicker.
Is it possible to select the features, video card drivers, applications, etc
and then download only those files needed for that config? It would save me
time and hard drive space if I could. In fact it would eliminate a
partition I use to first download to before I install.
Thanks,
Mark
