| it has the ht flag, so yes, it does :-) You have to compile your kernel with smp support to get it working though |

Damn. I have run it without HT for one year already. What a waste! |

| No, all cpus from Intel since pentium3 have the ht flag. It doesn't mean you actually have a sibling thread unit. |

Seems easy to answer
| Code: | | model name : Intel(R) Pentium(R) 4 CPU 2.40GHz |
Intel start HT with 3.06 Pentium 4 (533 fsb) & newer core with 2.8ghz cpu (for 800 fsb)
So, no, intel didn't make a 2.4 with HT yet
| Code: | model name : Intel(R) Pentium(R) 4 CPU 2.80GHz
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr
|
should be the xptr... |

Yeah, I've also that ht-flag & my machine is P4 1.4Ghz (so definitely not ht-cpu) ,so why it's there

I have an Intel P4 2.4 with HT - 2.4C 800Mhz FSB so I am pretty sure they did make them |
