Debian with Dual Xeon processor.
 

Hello,
I installed Debian 3.0 on IBM server xSeries 345 with dual Xeon processor. In cpuinfo file has 4 processor is ok but when I run top, I saw only one cpu in process. What I have do special for enable other cpu? How can I do?

It sounds like you are running a kernel that does not support multiple processors. Have you installed the most recent kernel?

How can I do? Where I can get it?
Thanks.

Well....there are a number of different ways to do this. The command line method would be with apt-get, but I have a feeling that is not going to work for you.

In your case, I am going to assume that you are using a GUI such as gnome or KDE, in which case the best thing I can think of would be a program called Synaptic. If this is not the case, then aptitude is probably right up your alley. There is documentation out there on how to use each of these programs.

Just to be sure, when running top, press the "i" key, usually if smp is disabled, then cpuinfo wll only show one processor iirc

Actually, I think you are referring to the "I" command, not the lowercase version. The lowercase version toggles idle tasks, whereas the uppercase version toggles between IRIX mode and Solaris SMP mode. By default in debian, IRIX mode is enabled.

Thank you Wells, my linux no have GUI. Could you tell me how can I do on CLI mode,please.
I will try to do.

Thanks

For CLI mode, aptitude or dselect are your friends. I recommend aptitude over dselect, as it is more user friendly.
