I did a “set-defaults” here… So this is the first head scratcher.  (Could this be a sign that the NVRAM is nearing battery failure ?)

If that’s the case - I would also need some Solaris image/disk on hand to run this tool as from what I can tell there is no such cg14config(-like) tool in NetBSD.

The ss20 is/was a nice sparc box - good to see it still running!

Could I ask what NetBSD version you were using? There have been
improvements to the sx/cg14 drivers since netbsd-9 (and possibly some
since netbsd-10), so if you're trying netbsd-9 you  might find better
luck from the netbsd-10 link at http://nyftp.netbsd.org/

You may also find someone who knows more about NetBSD's handling of
this on port-sparc at netbsd.org :)

Thanks


David
