Hello dear developers!
Here is my system configuration.

I have Pentium D CPU, which many Windows utilities like cpuz, wcpuid, everest identify as D 930 (Dual Core, 3GHz). From Intel site I find out that it has no HT feature, nor Windows XP identify it as HT.
Why do I have "ht" flag in cpuinfo? -----------------------------------

So, how must I choose kernel settings like:
number of CPU's? HT support?
