I have an intel p4 3Gz chip
last week I showed 2 cpus
today I redid arch it shows 1
is there an SMP kernel I am suppsoed to be using?
I dont want to limit arch to being as slow as 1 cpu if it cna enabel 2 vitual cpus

It shows 2 cpus because there is hyper threading on the cpu , which acts like another cpu

Can you post uname -a and also cat /proc/cpuinfo

This is the exact same physical box. It showed a 0 and a 1 cpu. I don't have anything saved to show that Is there something I am not enabling so that arch will see the hyperthreading?

yess, I guess I hit default in the bios, it turned off hyperthreading!!!! lol now its fine
