Hi,

I currently have a Abit BP6 motherboard with 2 celeron 466's. I'm not sure
how to make FreeBSD make use of both these processors, can anyone give me a
point in the right direction as to where I should be looking?

I added SMP options in the kernel config, but I wasn't too sure what to use
so I left the defaults in:
# To make an SMP kernel, the next two are needed
options   SMP     # Symmetric MultiProcessor Kernel
options   APIC_IO     # Symmetric (APIC) I/O
# Optionally these may need tweaked, (defaults shown):
options   NCPU=2      # number of CPUs
options   NBUS=4      # number of busses
options   NAPIC=1     # number of IO APICs
options   NINTR=24    # number of INTs

Would that be okay? And how can I test that I am using both processors? I
tried running a CPU intensive program and the load average never went over
1, which I thought would reach 2 if 2 processors were in use.

Any help appreciated.

Thanks,
Andy.
