I've recently received a Mips Magnum 4000SC-50, and would like to get NetBSD
installed on it.  To my knowledge, it has the NT/ARC firmware loaded.  I don't
presently have a spare keyboard/monitor, and was wondering if it's possible
to get ARC to come up over the serial 1 port.  Does anyone know how this
could be accomplished?  There's a jumper marked "J4" right next to the serial
controller chip.  Might this be involved?  It isn't jumpered at present...

Any help would be very much appreciated.

Cheers,
-Mark
