Thanks for the suggestions, but it will probably be a couple of days
before I try that again.  Unfortunately, I will have to start again
since I removed the BE that wouldn't boot up.  I had tested that it
would boot up in single user mode, but I had only tried removing a
couple of things from /etc/rc.conf.  I will try your suggestions before
I try the next time.

Thanks for your help.
