Hi Patrick,
Yes, they are both on the same subnet. Since last night ( and 8 hours sleep
later) I re-examined my set up + with advice from Patrick Morris + yourself I
downloaded a tftpboot image, it was at this point I then realised after
checking my setup again that I had mis typed the hex equivalent of the IP
address, I had missed out the leading 0 but had an extra 0 in the middle
....fool that I am....
It boots like a dream now.

This confused the hell out of me at the beginning, running rarp on a 2.4
kernel gave "this kernel does not support rarp" messages. A bit of googling
later I found a nice post that stated "rarp is a userland process in 2.4" so
I installed the rarpd package from the Debian site added the ethers info &
when the SS20 was attempting to load the image I got the messages shown in
the logs.

This still comes up, but everything seems to be downloading properly.....

Thank you very much for your help it is much appreciated. I suppose I should
document this properly, it may be useful in the future?? My next task is to
build a filesystem to use the SS20's as an Xterm.....
