thanks for the diff i made the (first) change; setting to 1, and dmesg gives: --snip-- real memory = 536346624 (523776K bytes) avail memory = 517992448 (505852K bytes) Programming 24 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 Programming 24 pins in IOAPIC #1 Programming 24 pins in IOAPIC #2 FreeBSD/SMP: Multiprocessor motherboard cpu0 (BSP): apic id: 0, version: 0x00050014, at 0xfee00000 cpu1 (AP): apic id: 6, version: 0x00000000, at 0xfee00000 io0 (APIC): apic id: 2, version: 0x00178020, at 0xfec00000 io1 (APIC): apic id: 3, version: 0x00178020, at 0xfec80000 io2 (APIC): apic id: 4, version: 0x00178020, at 0xfec80400 Preloaded elf kernel "kernel" at 0xc03b2000. --snip-- so theres no error, but my inclination is that its still not enabling the 2nd cpu. again, i'm not sure how to verify for SURE whether it is or not.. i've just been running top and looking for 2 cpu's running is there something in dmesg i should be looking for in particular? i'm going to try now by setting physical_cpu to 2..11 as you indicated and see what happens thanks nathan > Well, in teh above message, 6 is the APIC ID, not 1.
