Hi Magnus

Up to now i failed getting the bootp (.. and NFS mount) stuff running.

Here some details from the linux configuration:

/etc/bootptab

              :gw=10.1.20.2:\

              :bf=null:\
              :sa=10.1.20.2:\
              :td=/tftpboot

In directory /tftpboot i put all the stuff from mbxroot.min.gz from http://www.ppc.kernel.org/embedded.html.

Any ideas why it doesn't start???

TIA, Ruedi
