I followed the instructions here: http://nixcraft.com/file-servers/14803-how-centos-5-pxe-linux-installation-s..., along with a few other sources that were less successful, and I finally got a pxe boot going. I'm using CentOS 5.3 x86_64 media as the source.
The server boots, but keeps hanging.
Does anyone know what could be wrong? I just need to get to a shell and get into fdisk.
Try using trk. Works over here for me but I use it for fixing Windows desktops...
