rhel5 nfs install

I have an NFS share with ISOs [1]. When installing a RHEL4 system the boot disk offers to use an NFS source. I am then able to bring up eth0, mount the NFS server and complete the install with one CD. RHEL5 is different and doesn't have a KickStart CD. However, you can achieve the same effect by booting from the first CD with "linux askmethod". The installer will will then prompt for the NFS server details.
