This thread ended up outside of this forum so I thought it would be prudent of 
me to post the rest of the conversation so that no one thinks it was just left 
without a response.

@steve
Hi again Geoff -

I just checked my files, and I successfully booted 
debian-sarge-256MB-05-01-2006.tar that I found on the TS website.

I changed the last line of the /etc/fstab file in the above distribution to 
read something like the following:

192.168.0.1:/srv/ts7200 / nfs exec,dev,suid 1 1

where the ip address is that of the laptop serving the kernel.

@me
Thanks, I'll have to give it a try later when I get home from work. I had 
actually changed the fstab entry to what you have below, the only exception 
being that I'm on a different subnet. I also hadn't tried specifying the fixed 
IP in the boot script. Thanks a lot for you help, I'll post back my results 
later on.

@me
It looks like the tarball that I was trying to use was looking for a 2.6 
kernel, I gave the one you suggested below a try but there was still a problem 
with something. I opted to give up and dust off an old compact flash card which 
I'm now using, I'll have to shelf this until I get motivated enough to try and 
bootload a 2.6 kernel. Thanks again for your help.
