This is a description on how to do an installation of debian-edu using netboot.
I have a mirror http://bzz.no/debian-edu/ which is used for the purposes
You might fetch the http://bzz.no/debian-edu/netboot/mini.iso mini.iso and burn it as a CD, or you can set up tftpboot and use the [http://bzz.no/debian-edu/netboot/debian-installer/i386/linux kernel] and [http://bzz.no/debian-edu/netboot/debian-installer/i386/initrd.gz initrd] that I built, or you can fetch a [http://bzz.no/debian-edu/netboot/netboot.tar.gz tarfile] with the files inside
Select Language/country/keyboard as usual, and if your network already is running a dhcp-server I guess you can use that (I have not tested that). When the installer asks which mirror to use, then select "enter manually", and use bzz.no as server name and /debian-edu as subfolder (or whatever it's called). Then continue the installation, by selecting profile, reformatting disks and set password as usual.
To warn you: the mirror is not on the fastest line, so please use a proxy if you want to do more than one installation. Also, there is no auto-update on the mirror, so you wont get the newest and latest udebs and debs. But it's a start. I've only tested a main-server profile (no combination at all), and manual network settings (10.0.2.2 as address, 255.255.254.0 as netmask, 10.0.2.1 as gateway and dns-server, tjener as hostname, intern as domain-name)
