I am running AT&T 386 UNIX on a no-name '386 clone.  It works just
fine but I am not able to shut it down to reboot itself other than
from right in front of it.  Since I operate it from remote I would
like to find a way to reboot from remote.

I'm aware of the restrictions imposed by the /etc/shutdown script
but that's not my question.  TFM says that run level 5 stops UNIX
and goes to the firmware monitor, run level 6 reboots to the state
defined by initdefault entry in /etc/inittab.  As best I can tell
neither does anything but stall the system in some odd state from
which a front panel reset and fsck is the only exit.  I don't think
this is a case of the 3B2 man pages being shipped with 386 UNIX
because the man page specifically mentions the 80386.

Has anyone been able to use run levels 5 or 6 with any interesting
results?  My 3B2 books show that it really will go into it's firmware
monitor, but of course the '386 doesn't have one.  I know that there
is a ROM BIOS vector that will cause a reboot and I have used it in
DOS applications when I knew the only safe exit was to reboot.  I
don't know where it is or how to use it from UNIX though.  Any ideas
on that one?  Thanks,
