Hi
I just installed debian (sarge) on a Dual P-II system. The kernel that was
installed was: kernel-image-2.6.5-1-386
Then I installed kernel-image-2.6.8-1-686-smp using apt-get and added it using
grub....
After re-booting... the top program shows only one CPU.
But the output of dmesg and /proc/cpuinfo appears to have recognized the 2nd
CPU. Any ideas if
(a) the 2nd CPU is being used OR
(b) it's not being used
If it's not being used, any tips on what I should do to get Linux to use the
second CPU? I've read the SMP HOWTO but did not find anything much. It said
something about "MPS version 1.4 and 1.1" .. I tried to change that in the
system bios.. but no joy...
Any ideas what I can do to get this to work?
Regards
Rishi
