Re: Is the kernel for sun4m SMP capable ?

Sure is - just not the one that ships with the default install. You’ll either need to drop in a pre-built GENERIC.MP kernel, or compile the kernel with the multiprocessor support enabled:

I will say - on the SS20 it makes quite a performance difference.
Thank you. It is silly to run a multi-cpu machine in non-SMP mode.
I can only think of some kernel dev test reasons to do so. This now
confirms why the install process ( and after effects ) were fishy

This installer now uses the new `sysinst' installer tool by default. To
use the old install or upgrade shell scripts instead, enter the options
(OI) for Old Install or (OU) for Old Upgrade.
The script-based installers may be removed in a future release.

I have two SS20 units here and more parts than reasonable. I may leave
this 60MHz unit running Solaris 8 or perhaps strip out the CPU's and
replace them with the 200MHz parts. Trying to compile a new kernel is
a good idea but I would rather use a faster CPU for that task. Sadly
the 125MHz hyperSPARC Module is the best one may do ( safely ) with an
OpenBOOT PROM ver 2.19.
I will see what I can get running.
