I have Ubuntu 9.10 install on an AMD quad core asus mb, but it is clear from running the system monitor that is has only "seen" one CPU.

On another system I have an Intel dual core, and that shows both cores as expected.

Any ideas?

How will that help me? It seems to be only a Windows executible, and just show the type of mb and CPU. My problem is that Ubuntu 9.10 treats it as a single core (apparently).

Ubuntu doesn't have to see 4 cores for the cpu to work. Only the motherboard has to have support for your cpu. Ubuntu is an imperfect software; if you want more toys and support, go with windows ultimate. It works great, especially with a directx 10 or 11 video card.

Actually, it was the BIOS - I went through it and enabled "ACPI" and (?) "EACPI" and now I see 4 cores as I'd hoped.
