Cris,

Had a similar problem myself.  What I did was copied some binaries from a
68010 to my Sun3 (68020).  Once I tried to re-boot that error message kept
coming up.  What 'csh' is trying to do is `exec' a binary that you
possibly moved, that is not compatible with your system.  In my case, it
was 'awk', which placed that same message into the file /etc/motd. 

Look in /etc/motd. I bet you $$$ that this message is in this file.
8^> ->  Cannot exec binary file.

At boot time, the files /etc/rc & /etc/rc.local, looks at a couple files
and tries to build a string using both 'sed' and 'awk', if these binaries
are incorrect, as they were in my case, they spout out spurious
information into the pipeline to /etc/motd.

This might be a solution, look at the replaced binaries, see if there were
any name collisions, probably is one of the binaries in /bin like 'sed' or
'awk' that is used at boot time that caused this.

Hope this helps,
Dave

Yes, I have, to see exactly where it is from, look at the file /etc/rc or
/etc/rc.local, and look for shell script calls to /bin/*, this is most likely
where your problem is located.
