linux gurus, SMP?

[exciv2000]

The machine I have linux running on has a dual proc mobo in it. I originally installed RH linux 7.2 with only one proc in, and just today installed the 2nd proc. I can't tell if it's working or not, but I'm pretty sure that it's not. I can see when the system boots up that it lists Deschutes x 2 for the processor, so the bios is seeing both of them, but the kernel I don't think is. I just compiled a new kernel, 2.4.9-21 and enabled SMP in it (symmetric multi-processing), set that up within lilo to use it, but when I reboot, everything looks the same. The KDE System Guard (in KDE 3.0) shows only 1 cpu load (apparently for cpu0). When I go to Preferences -> information -> Processor, it only shows cpu0 as well. Anybody know how to get the second proc showing and working in linux? FWIW, Anaconda didn't pick it up either during bootup.

nevermind, my friend is trying to figure it out over ssh.

cat /proc/cpuinfo

If you compile in SMP then it *should* be working. I've never actually ran an SMP machine though so that's about all I can say...

I'm running mandrake on a dual p2 450, but it already had the second processor when I installed the OS so it appears to be working properly. Good luck ,and keep us posted.

it just works, if you have SMP gen'ed into the kernel.

I dunno, but it works now... my friend SSH'd into my box and fixed something. I returned from work today and everything works great, much faster too. Dual PII 333s. I am pretty sure I compiled SMP into the kernel, but there was something else in there I missed apparently.
KDE 3.0 is nice btw :)
