does anyone know how to turn off hyperthreading in the system bios?

I'll bet the manufacturer of your computer knows. And since there are many
BIOSes out there, if you want specific information, the manufacturer is your
best source.

Why on earth would you want to meddle with that...it makes things work
faster and smoother!

Well considering its benefits sytem-wise, and the fact that I haven't come
across anything that is incompatible with it so far, I would suggest
ditching anything that isn't rather than possibly screwing up the
motherboard. Then getting on that particular software manufacturer's case
to make it compatible.
Just my thoughts!

It should also be noted that if you do turn off hyperthreading, that the
installation of Windows you currently have will no longer function--you will
need to reinstall windows since the Hardware Abstraction Layer is different
between a one processor (hyperthreading off) and two processor (as far as
Windows is concerned, this is what you have with hyperthreading on)

If you go into your BIOS setup routine, it should be evident, by a simple
menu choice, which you can disable, or enable, with no ill consequences. I
have done this often with an HP x4000 workstation, that has dual Intel XEON
processors, both with Hyperthreading. When it's enabled, my system appears
to have four CPUs!
I also have a Sony, single Intel Pentium 4, 3.2GHz, with
Hyperthreading...that is also disabled/enabled, in the same manner.

This is not always true. There is some overhead, in supporting
Hyperthreading. There are also some applications that are not compatible
with it.

There is no way that disabling Hyperthreading is going to screw-up the
motherboard.

This is not correct. You can disable, and re-enable, Hyperthreading all you
want, and Windows will boot just fine!
If you want to check the processor properties, to make sure they're correct,
or change them, so that they are, do the following:
Right click on My Computer
Left click on Manage
Left click on Device Manager
Left click on the + Computer
Right click on the processor
Left click on Update Driver
Left click on Properties
Left click on the Driver tab
Click on Update Driver
Using the above, you can toggle your Windows OS, to use either a single, or
multi-processor, configuration.

Thank you for the correction. It would appear I have been misinformed. I ran
into an issue not too long ago where hyperthreading was switched off and we
were unable to get the machine to function properly until a windows
repair--and then there was still an issue with ACPI, that we needed to
completely reinstall Windows to alleviate. My colleague was adamant about it
being due to HT being turned off.
I did as you suggested and had no issues, so it would appear that whatever
my problem was it was not hyperthreading being disabled (perhaps it was my
colleague). It certainly helps to verify things, doesn't it?
Thank you again.

unfortunately, digidesigns protools audio software is not really meant for
pc's so hyperthreading is a major issue. the product is necessary and quite
pricy so, i have to resort to this. can you tell me exactly how to get into
the bios setup? thanks for all the help.

Depending on your system, when you first power up, during the post, prior to
loading Windows, you should see reference about hitting F1, or F2, possibly
F10, or Esc, to enter Setup. If you don't see it, it should still work,
just that someone chose to hide that option from the user. After you
successfully get into Setup, you will be presented with a text screen
showing various options for your hardware. Typically, you navigate using
the Tab, and Cursor keys, PgUp / PgDn, then depending on the BIOS, you
either use the cursor keys, or + / -, or Enter, to toggle, or change the
settings. Be careful, as there are options in the BIOS, that could render
your system unbootable. So only change what you're familiar with, or
understand. If you get into trouble, there are usually default options that
should get you back up, and running, but not necessarily at optimal
settings.
Use something like Google, to search the web for BIOS options, directions,
etc. You should find helpful information there also.
