Advanced settings
On some computer models, the Advanced settings menu includes a setting to
enable or disable HyperThreading. This feature works only with
HyperThreading-aware operating systems, such as Windows 7 and Windows Vista.
The default setting for HyperThreading is enabled. However, if you are not using a
HyperThreading-aware operating system and you select Set Defaults for
HyperThreading, your computer performance might be degraded. Therefore, you
should always set HyperThreading to Disabled unless you are sure your operating
system supports HyperThreading.
Exiting from the Setup Utility program
After you finish viewing or changing settings, press Esc to return to the Setup
Utility program menu (you might have to press Esc several times). If you want to
save the new settings, select Save Settings or Save and exit the Setup Utility.
Otherwise, your changes will not be saved.
