[FUGSPBR] HyperThreading

[Marcio Jota Coelho]

Compilei meu Kernel como o Renato Frederick indicou

#cpu            I386_CPU
#cpu            I486_CPU

E descomente

# To make an SMP kernel, the next two are needed
options         SMP                     # Symmetric MultiProcessor Kernel
options         APIC_IO                 # Symmetric (APIC) I/O


boot normal....
mas não deveria aparecer no top mais um cpu???
na duvida eu utilizei o
#sysctl machdep.hlt_logical_cpus=0

mas ele me da um erro:
sysctl: unknown oid 'machdep.hlt_logical_cpus'

procurei algumas coisas no google e encontri um site que fala que tenho que
liberar na BIOS da placa alguma coisa relacionada com cpu logico..
mas não encontri nada sobre isso na minha placa mae.
