The failure is in that X begins but never brings up the installation screens.
Here is my grub.conf that I use to keep my various testbed boots:

The NFS paths are correct, but only the "Fedora 10 NFS" works properly. Have I got something obviously wrong? The /boot/f11 directory contains all the files from isolinux and boot.iso and install.img from the images/ directory.
