Good morning everyone. I has a couple of quick questions regarding taking advantage of dual processors on a server that I have for our company. Now, i've never setup a FreeBSD box on a system that has 2 CPU's so this is my first shot at it. Following the handbook, I recompiled my kernel with support for SMP. After a quick reboot, I took a look at dmesg and here is what I see: CPU: Intel Pentium III (996.85-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x68a Stepping = 10 Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE> real memory = 2147401728 (2097072K bytes) avail memory = 2086166528 (2037272K bytes) APIC_IO: MP table broken: 8259->APIC entry missing! Programming 16 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 Programming 16 pins in IOAPIC #1 FreeBSD/SMP: Multiprocessor motherboard: 2 CPUs cpu0 (BSP): apic id: 3, version: 0x00040011, at 0xfee00000 cpu1 (AP): apic id: 0, version: 0x00040011, at 0xfee00000 io0 (APIC): apic id: 14, version: 0x000f0011, at 0xfec00000 io1 (APIC): apic id: 13, version: 0x000f0011, at 0xfec01000 Preloaded elf kernel "kernel" at 0xc0551000. Pentium Pro MTRR support enabled It looks like it is working for 2 CPU's, but what is that entry where the line starts with APIC_IO...? Also, how can I do some testing to ensure both CPU's are being utilized. I appreciate the help. Jason
