Ok, sorry for the delay. I had to run out and pick someone up.
I got nowhere with the previous version of ltools. The new 1.8rc1 version installed without problems.
But...(you knew there was a but) Now the xbox is stuck with a manual ip address in the wrong subnet.
I was looking at this on the old version and found that every time I changed the IP configuration from manual to automatic, running Run Linix would set it back to manual with an IP of 192.168.0.3. Now that I've got the new dashboard installed, I'm still have 192.168.0.3 as an IP with no obvious way to change it. When I invoke the MS dashboard it comes up, but, when I go to network setup, it boots back to the Ltools dashboard without allowing me to change anything.
