HyperThreading...

To completely disable HT in Windows XP you have to disable it in the BIOS
and then reinstall Windows XP.

If I disable HT in the BIOS will I have to reinstall Windows XP ?
Or will windows recgonize that I have disabled the bios and load the correct
HAL/Drivers?

I am not 100% sure (cover my ass), but I think you can disable it in the
bios and the multi-proc hal will still work ok. it may not be optimum,
but it should work. I seem to recall users turning it on/off as needed
for various purposes and not being required to reinstall. [what you can't
do is install w/ it off, and then turn it on; I think... ;-) ]

the hal is chosen only at XPsetup time, it is not dynamically chosen at
boot time.

I was able to disable it w/o reinstalling the OS. As far as I know the
multi-processor hal works fine when going from dual to single.

I've just got to ask. Why would a person want to disable Hyperthreading?
