Processor #0 15:11 APIC version 16 ACPI: LAPIC (acpi_id[0x01] lapic_id[0x01] enabled) Processor #1 15:11 APIC version 16 ACPI: LAPIC_NMI (acpi_id[0x00] dfl dfl lint[0x1]) then further down I see: Checking aperture... CPU 0: aperture @ d4f8000000 size 32 MB Aperture from northbridge cpu 0 too small (32 MB) No AGP bridge found SMP: Allowing 2 CPUs, 0 hotplug CPUs Built 1 zonelists Kernel command line: ro root=/dev/hda2 Initializing CPU#0 which clearly shows that it sees 2 processors (an AMD Athlon 64 X2) and enabled SMP for it. > Trotter > > __________________________________________________ > Do You Yahoo!? > Tired of spam?
