Basically in order to boot from the network you need the contents of os/$arch/images/pxeboot/ for your system architecture. You can then use kickstart to point to a media you want to use for the actual installation. This can be that of cdrom, url, nfs, etc. You pass the kickstart parameter to your client using the 'ks=' parameter. the installation media can be from a local rsync of the CentOS repository (to save money) or to a mirror of your choice that may be local to you. Feel free to ask any questions. -- James A.

So with the help of some volunteers we set up a Centos-install-fest here at work and installed some 30 laptops in an hour. (More would have been possible, the limited factor was the number of Internet cables I could muster.) So many thanks.
