You need a SMP motherboard. But you DON'T need two or more cpu's. I removed a cpu from a dual system. I replaced the cpu with one of = those dummy tingys, restarted the server and it was up and running. :) The kernel says: APIC_IO: Testing 8254 interrupt delivery APIC_IO: Broken MP table detected: 8254 is not connected to IOAPIC #0 = intpin 2 APIC_IO: routing 8254 via 8259 and IOAPIC #0 intpin 0 =D8ystein -----Original Message----- From: Ruben de Groot [mailto:fbsd-q@bzerk.org] Sent: Wednesday, August 21, 2002 13:08 To: Ceri Davies Cc: Dan Nelson; FreeBSD Questions Subject: Re: Freebsd and multi-cpu systems On Wed, Aug 21, 2002 at 11:45:40AM +0100, Ceri Davies typed: > On Tue, Aug 20, 2002 at 05:27:25PM -0500, Dan Nelson wrote: > >=20 > > Just add > >=20 > > options SMP # Symmetric MultiProcessor Kernel > > options APIC_IO # Symmetric (APIC) I/O > >=20 > > to your kernel and rebuild.
