Hi Jim,
Let me try that and update, I thought about this, but was not quite sure, if I can do like this.
:) I’m trying to get it to work in one of the methods, either NFS or CF mode, but unfortunately both are not working. CF it gives some different kernel panic while trying to mount, and NFS, it fails at login.
Let me try this.
Thanks
Balaji R

ok then, create a regular user account and see if you can login with that.
(create an entry in /etc/passwd and create a home directory etc)
If you can then you can use "su" become root.
