[Wlug] Network Install

I freely confess my inexperience. I have done a number of successful CDROM installs from Mandrake 6.1-7.1-7.2. I have an old box I scrounged but without a servicable CDROM drive. I want to install Linux on it, but need to do a Network Install. I am not finding detailed documentation on this and will continue to hunt. If anyone has a hint as to where to look or experience to kick me in the pants in the right direction I would be terribly grateful. Thanks Colin
