I'm not so sure. All cat /proc/cpuinfo will do is tell you how many CPUs you HAVE not necessarily how many are being used. If you put a uni-processor kernel on a dual processor machine what does cat /proc/cpuinfo show?
I've been there at one stage while upgrading my system's hardware. It will show only one CPU.
Mine showed two cpus by pressing 1, but i don't remember selecting uni or multi processor kernel during install. Is this something that Suse 9.2 detect and install?
If you have two CPUs or an HT CPU SuSE will automatically install the SMP kernel.
Correct. But if you install SuSE on a single, non-HyperThreading processor and then upgrade your system with a HT CPU, you will be in the situation where only one processor core will be active and /proc/cpuinfo will show only a single CPU. To fully exploit your new hardware, you have to use YaST to install the SMP kernel (and then most likely use YOU to upgrade it to the latest available kernel). That's what happened to me.
