Re: [expert] enable SMP
IIRC, APIC is the part of the chipset that controls SMP. Can you run in
SMP mode if you use noapic?

Ok. Here's the patch. It's for kernel 2.3.45. You need to
install THAT kernel, and then patch it with the attached
patch (my apologies to the list for sending a binary...)
I'm not sure WHAT APIC is, but to use it at LILO, just type
" noapic", i.e. "linux noapic" and hit
enter.

Kernel Panic. Kernel compiled for PPro+ assumes local APIC without read-before write bug In Swapper task Not Syncing. It stops right there. Whats the patch? How do you do the noapic at lilo?

The solution (that *I* found) was to boot with a "noapic" option at LILO. It complains, but at least it boots. But I've got other problems which keep me from booting to SMP on my Dual-200 PPro board.

Im having a bit of a problem trying to compile 2.2.13 for smp. My machine is a dual 166 ppro w/160m ram on a intel mother board that has the AIC7870 controller on board. I also am running a Intel EE pro100 nic. The problem is as soon as it shows both cpu's during startup it crashes.
