Hi gang!
At work I have a DL320 G2 machine I use as my desktop (I know,
weird!...).
Back when I ran RHEL WS 2.1 on it, it always ran a SMP kernel because it
has a HypterThread capable processor.
When I installed (fresh from scratch) Centos 4.4 on it a while back,
though,
Centos installed only the UP kernel.
I've looked in the BIOS for settings to enable/disable HT support and
I don't see anything.
I've force-installed the SMP kernel and when I boot it it doesn't seem
to think there's anything thre but a normal UP CPU.
Should it not show two CPUs in top, and in suitable places in /proc like
the earlier OS did? (at least when running a SMP kernel)
Ideas welcome.
Thanks!
The DL-320 G2's I've got (6 at last count) running CentOS/RHEL 3 and 4
all show up in /proc/cpuinfo as single-core with no hyperthreading.
Here's the example output from one of them:

odd. I have a dual xeon of about that generation that shows up
as.. note this is family 15, model 2, stepping 7, while yours is
stepping 15/2/9, which would be later. now, mine are running 2.4
(centos3 and centos2.1)
