hi!

i just bought an Intel Pentium D-930 (3ghz dual-core)
and wonder why i just only have CPU0 and CPU1, when i compile with SMP...

sysctl says:
machdep.cpu_idle_hlt: 0

is it right or i should see CPU 2 and 3 starting during the boot?

thanks for your help!

ps: i even compiled this option in kernel, can't see any change

options MPTABLE_FORCE_HTT # Enable HTT CPUs with the MP Table

Sounds right to me - the 930 is a dual core and will show up as two cpu's
cpu0 and cpu1.

The early dual core's don't support hyperthreading - the Pentium-D extreme
edition does (Pentium D-955 at 3.46Ghz is one) and will show up as 4 cpu's.
Currently at 3x the price.
