Hi
If you intend to run multiple processors, you are limited to intel
processors. most likley you are limited to 4 pentium 200s. since it is
socket 5 you can not use pentium MMX chips without a converter, and
(someone please correct me if I am wrong) these converters may kill the
SMP capability. with the exception of the AMD K7, intel chips are the
only x86 chips that can do SMP. I believe that the K5/K6 used an openPIC
that would theoreticaly allow SMP, but no board uses this. as far as the
computer itself, I'm not sure if it can reliably do SMP in Linux. I think
that the intel chipsets support for socket5/7 is 2 processors, so it must
use a non-intel chipset.
It will probably be difficult to get this working because you would need
to find two to four MATCHED pentium chips. the non-mmx chips are getting
hard to find now, and matched chips are even harder to find.
(matched=same or similar CPU stepping, look in /proc/cpuinfo)
