This is a dmesg from an Intel D830 box: CPU: Genuine Intel(R) CPU 3.20GHz (3217.43-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf47 Stepping = 7 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,P SE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x649d<SSE3,RSVD2,MON,DS_CPL,EST,CNTX-ID,CX16,<b14>> AMD Features=0x20100000<NX,LM> AMD Features2=0x1<LAHF> Cores per package: 2 I think you do have a single processor with hyperthreading (logical CPUs) and not a dual-core model. To get hyperthreading up and running, you need to add: machdep.hyperthreading_allowed=1 to /etc/sysctl.conf or change it manually. Please google for the security implications of doing this first though. -- Juha http://www.geekzone.co.nz/juha
