I have a Dell GX280 with windows XP service pack 1 and enabled hyperthreading
in the bios. If I look in device manager under processors I see two
processors. When I look in task manager under performance I only see one
instance for the processor. Would like to know if this is normal and is the
OS taking using hyperthreading to its fullest?

Hi,

In Task Manager - Performance tab, go to View - and enabled the option
to show multiple graphs for multiple CPUs.

For more information take a look at the following article.

Your suggestion to show multiple graphs for multiple CPUs is not an option
that I have.
