Root-Over NFS Diskless booting

[Michael Taylor]

I have installed Grub and I am using it to do network booting. I have
bootp set up where it will get a IP, and it can pull down a kernel off
of my server using tftp and boot from it. But when i pass arguments to
the kernel to use NFS for a ROOT Filesystem i get this error. And i have
not found a way around it at all.

grub> bootp
grub> root (nd)
grub>kernel /vmlinuz-2.4.9 root=/dev/nfs nfsroot=192.168.0.1:/
grub>boot


I'm exporting the entire filesystem off of the server, just for
testing,  i'm tried creating mini filesystems to boot it with, but get
the same error with them too.

It will start booting the 2.4.9 kernel, but when it comes time to mount
the / filesystem i get this error.

RPC Call returned error 101
Root-NFS: Unable to get nfsd port number, using default
NFS Server returned error -101 while mounting /

I have root over nfs compiled in the kernel along with anyother includes
i would need.
There is a little more output than that, but it is not relevant. My NFS
server shows nothing in the logs anywhere of the attempt to mount a
share off of it. But i get this error when booting the diskless machine.

I'm not on the mailing list so if anyone responds please cc: the email
