hyperthreading on d845hv

According to powerleap Intel manufactured some rare P4 2.8GHz 400MHz FSB 478pin 512K Northwood CPU with hyperthreading (RK80532PC072512).
I recently purchased one and it runs well on my machine  with  intel d845hv mobo (faster than my old p4 1.6). But I cannot seem to find a way in the bios to enable hyperthreading. (Nor do I see the virtual CPU displayed in my task manager or device manager). Does anyone know what I can do? The latest bios supposedly has Machine Check work around for HyperThreading...whatever that means.

That'a a pretty expensive processor ($240?) - you could have taken your old P4 1.6 and boosted the FSB from 100 to 150 and gotten a P4 2.4 if your motherboard let you change it (I know, because I did this with mine).  If you change the cpu, even to a hyperthreaded one, you need to update the processor driver.  You should be using the ACPI Multiprocessor version in order to see two cpu graphs.

It is now unclear to me whether this proc supports HT or not (seems to depend where i get the spec)

Does your motherboard allow you to manually change the FSB from 100?  I had Asus motherboards which had this feature, but Intel motherboards tend to be not overclocker friendly.  The Northwood-A cpus were extremely easy to overclock; I had a P4 1.8 that went up to 2.7 with no problem.  None of the Northwood-A cpus with 400FSB were hyperthreading, as far as I know.

Don't think the d845hv supports hyperthreading :(
Which BIOS version do you have?  
If Hyperthreading is available on an Intel board it appears as an option in the BIOS Main Menu ("Hyper-threading Technology - Enable/Disable")
