Selecting Or Changing The Startup Device Sequence; Advanced Settings; Exiting From The Setup Utility Program - Lenovo THINKCENTRE 6393 Hardware Maintenance Manual

Selecting or changing the startup device sequence

To view or permanently change the configured startup device sequence, do the following:
1. Start the Setup Utility program (see "Starting the Setup Utility program" on page 39).
2. Select Startup.
3. Select Startup Sequence. See the information displayed on the right side of the screen.
4. Select the devices for the Primary Startup Sequence, the Automatic Startup Sequence, and the Error
Startup Sequence.
5. Select Exit from the Setup Utility menu and then Save Settings or Save and exit the Setup Utility.
If you have changed these settings and want to return to the default settings, select Load Default Settings
on the Exit menu.

Advanced settings

On some computer models the Advanced settings menu includes a setting to Enable/Disable
HyperThreading. This feature works only with HyperThreading-aware operating systems, such as Microsoft
Windows XP and Windows Vista™. The default setting for HyperThreading is Enabled. However, if you
select Set Defaults and are using an operating system other than Windows XP or Windows Vista, the
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

When 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 & Exit Setup
before you exit. Otherwise, your changes will not be saved.
