If not, any idea when? I believe hyperthreading is fine with the latest kernels: you want SMP. However, I am not sure you actually have it: it came in on the non-Xeon CPUs when they reached/passed 3 Ghz, and I don't know whether Intel introduced new slower CPUs with it. The fact you have the BIOS option is a good indicator that the mobo supports those CPUs, but whether you have one is another question. -- Please, reply only to the list.
