Network install of SuSE 9

I recently purchased SuSE 9.0 Pro and was wondering where I can obtain the boot.iso file for SuSE 9 so that I can do network installs over the LAN from my NFS server? I thought in SuSE 8.2, this file was located in the /boot directory on CD1. I don't see any .iso files on any of the five CDs in 9.0. Thanks, Chris
