NetBSD/sparc Now With SMP
jschauma writes "Largely due to the efforts of Paul Kranenburg, NetBSD
-current now supports
SMP on sparc. It has been tested on a
SPARCstation 20/712, sun4/690 and other systems. See Matthew Green's
message to the port-sparc mailing list." (i386 got this back in October.)
My rickety old SS10 is a SS10BSX, so it would be a true waste to run anything but Solaris. In addition to two processors it has dual CG14 video hardware on the motherboard and there isn't a 'free' X server out there that supports single, let alone dual CG14 on a SS10.
