Actually, the CPU is in a raised floor computer room one floor beneath
the student lab.  I understand that the graphics console can be placed
up to 150 feet from the CPU, which is within distance of the lab.  So,
the reset button issue is not a problem.  I like your idea of controlling
whether the CPU can be booted in single-user mode with a MODE switch
setting (SGI should really consider implementing this). 

However, what I am really trying to do is to get the "System Maintenance
Menu" to display on /dev/ttyd1 *and* have the graphics monitor work too.

Several people have suggested asking for the password on a single-user
boot.  This is unacceptable since the "System Maintenance Menu" is still
displayed on the graphics monitor and not /dev/ttyd1.

Other people have misunderstood my question, thinking that I only wanted
to get rid of the console window upon login.

Is it really true that you cannot have /dev/ttyd1 be the real console
and be able to use the graphics console at the same time?
