Syslinux - Dec 2002 - Root-NFS not mounting using PXELinux - error 101

I seem to be having trouble getting the NFS root filesystem to mount after
the kernel boots. As per thread from 2002 16 January
(http://www.zytor.com/pipermail/syslinux/2002-January/000028.html), I
double checked my DHCP config files, but to no avail. It cannot seem to
attach to the mountd port on the bootserver. Here is some output from the
kernel:

Here is the dhcpd.conf file.

Frankly, I am out of ideas as to which thing to change in order to make it
work.  I tried using mknbi-linux on the kernel and all that does is cause
a weird rainbow ascii filled screen when the kernel tries to boot. Should
I be doing anything special to the kernel in enable this feature, besides
the kernel configuration changes?  I did an 'rdev linux /dev/nfs' on the
kernel.

Thanks

You need to give the kernel some way to know what it's IP address is.
You need either ip=dhcp on the append line or the "ipappend 1" option.
