Devin, Thanks for answering my mail. I'm including my CUSTOM config file below. However, last night I was checking my bios and experimenting with changing some settings - then I changed them back. But when I did, the second processor was recognized and started working. It's now listed in dmesg output and it's warm to the touch. In my bios, I changed these settings (then changed them back): Use Multiprocessor Specification: (changed from 1.4 to 1.1 then back to 1.4) PCI IRQ's to IO-APIC mapping (changed from enabled to disabled then back) Processor retest (changed from no to yes then back to no) When I changed just the first (Use Multiprocessor Specification) - nothing changed that I could see. When I had all three switched, then the boot failed (hung). When I switched them back, then the second cpu was there, and the error message was gone. Any thoughts about that? msgs below. Thanks, Paul from dmesg: CPU: Pentium III/Pentium III Xeon/Celeron (696.41-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x683 Stepping = 3 Features=0x387fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA, CMOV,PAT,PSE36,PN,MMX,FXSR,SSE> real memory = 536805376 (524224K bytes) avail memory = 517750784 (505616K bytes) Programming 24 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 FreeBSD/SMP: Multiprocessor motherboard cpu0 (BSP): apic id: 1, version: 0x00040011, at 0xfee00000 cpu1 (AP): apic id: 0, version: 0x00040011, at 0xfee00000 io0 (APIC): apic id: 2, version: 0x00170011, at 0xfec00000 Preloaded elf kernel "kernel" at 0xc04aa000. from CUSTOM config file: # # CUSTOM -- Custom kernel configuration file for FreeBSD/i386 # # For more information on this file, please read the handbook section on # Kernel Configuration Files: # # http://www.FreeBSD.org/handbook/kernelconfig-config.html # # The handbook is also available locally in /usr/share/doc/handbook # if you've installed the doc distribution, otherwise always see the # FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the # latest information. # # An exhaustive list of options and more detailed explanations of the # device lines is also present in the ./LINT configuration file.

I have two Pentium III's and have the kernel compiled for smp. But dmesg indicates that only one of the processors is running (see below). I looked and both processors seem to be seated and connected identically, but only one is warm. > > > > Any ideas? > > > > Thanks, > > Paul > > > > bash-2.05# dmesg > > > > Copyright (c) 1992-2001 The FreeBSD Project. > > > > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > > > > The Regents of the University of California.
