I am wondering how I can get my system to work with my chip's dual-core? I am currently running an AMD Athlon 64 X2 4200+ Manchester 2000MHz FSB Socket 939 Dual Core.
I just downloaded Debian64 yesterday and installed it. I am currently running the apt-get kernel version '2.6.8-11-amd64-k8-smp.'
I would like to take advantage of the full power of my chip. I thought that using regular SMP would do the trick, but 'top' and 'cat /proc/cpuinfo' both only report one CPU, though uname -a does report I am using the x86_64 archtype (which I would hope).
So, can anyone help me get my dual-core running fully?
The SMP kernel is what you want. After you system boots open up a consol cat /proc/cpuinfo.
You should get something like this:
Code:

That will detail the individual processors or cores. I used that machine as an example because it shows you that dual cores look the same as physically different processors. In the example above the CPU0&1 are dual cores of one processor, CPU2&3 are the next processor, and so on.
As you can see, I only have one CPU it looks like. I was just talking with a colleague and he thought it may be a BIOS issue. This is a new computer and I may have to enable the second core on the system. The mother board I have is an:
ASUS A8V-E DELUXE K8T890 RET Socket 939 VIA K8T890 ATX AMD Motherboard Model #:A8V-E Deluxe
I have not really touched the BIOS at all, so it could be something that is not enabled by default.
Ya, that very well could be it. I have heard (but can't confirm cause I don't own one) that some motherboards need a bios update before they will work with the 2nd core.
I do know the newest version of that mainboards bios is 1008, is suppose to support dual core chips, and was released on 07/01/2005. That is near enough that many boards from retail outlets might not have that bios on them.

I seem to remember checking the BIOS version 2 weeks ago and found that it was the latest one. I hope I can enable that.
