What is exactly your CPU référence ? i noticed that my Celeron 2ghz wich
is not HT capable has also the ht flag in /proc/cpuinfo
HT capable Pentium 4 are :
3.06 Ghz P4B ( FSP533 )
all the P4C ( FSB800 ) ( 2.4C 2.6C 2.8C 3C ( 3.2C ) )
So, since your motherboard is only FSB533 capable, to enable
hyperthreading you must have a P4 3.06 Ghz, and none other.
