Win XP & Hyper-Threading

[Mike]

I recently built a new computer and chose Win XP PRO + SP1
as the OS.

Using a 3.0 GHz P4 w/ 800 FSB (Hyper-Threading capable) on
an Abit IC7-G MB (Again HT capable).

I have enable HT in the bios (bios has been flashed to
most recent version), and I see that HT is enabled during
system post.

However, XP does not recognize that I am running a Hyper
threaded system. The symptoms of this are the following:

1) Performance meter under the Task Manager shows only 1
processor.

2) Device Manager has only a single entry under Computer
(More on this later)

3) SiSoftware Sandra utility notes that HT is disabled,
likely due to OS settings.

Ok, one of my first atempts at a fix was to manually
update the device driver under the Computer category in
Device Manager. Initially it read a a Uniprocessor
machine, I updated it to use the Multiprocessor driver.
While the new driver seems to work fine, I still have no
indication of HT being active.

On other forums, people state that their device manager
has a 'Processor' category. I can't find that in my home
system or work system (I've tried all the view combos I
can think of too!)

Any help would be greatly appreciated!

Problem solved.

The starship-python article was a great resource. Sure
enough I had the wrong HAL installed. Abit's Award Bios
does not allow me to dis-able the ACPI... so I'm really
not sure what happened.

I figured I would try to just copy the kernal files from
the .cab and drop them in the system directory. Now I
really thought there was no way Windows would allow me to
overwrite kernal files... but it did!

The system even remained stable during that session, of
course I could never get XP to start after bootup again :)
But hey that was totally expected, I figured a full re-
format would be needed.

After re-installing everything was detected fine, I almost
curious enough to revert my bios back to its original
state... almost but not quite.

Thanks for the assist!
