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
