yes, a SingleCore CPU which supports HT has one physical core and one logical
core.
On Windows i saw a taskmanager screenshot where you can see four cores, the
user told it was a dualcore with hyper-threading, so i guess each HT capable
cpu shows all cores (physical and logical) but i wouldn't bet on that. Never
got a DualCore Xeon before so perhaps Xeon only shows physical cores.
but there is no setting to turn off/on (or something else) to get more than two
cores showed? Thanks!
