NetBSD should run on this. (The installer does not work correct, but
once the system is installed it is very stable.)=20

I don't know enough about POWER and its relation to PowerPC. This can be
everything from fast and simple to complex and very time consuming. Ask
on email@example.com. There are the gurus who have the knowledge
to give you a better answer.

I am sure it will. There are many RS6k machines out there and many
people who like NetBSD.

I think it has the same limits as every SMP implementation (with a big
kernel lock). So, depending on the task you have to do, the practical
limit is from 4 to 8. It may run on more CPUs, but this would be
inefficient. This is no limit in NetBSD, it is a systematic limit in SMP
systems. You need a different architecture for more CPUs. Somthing like
a cluster (RS/6000 SP, VAX/Alpha with OpenVMS or Tru64-Unix,
Linux-MOSIX, ...) or NUMA (Sequent Dynix, SGI IRIX, ...).=20
