1. Start the IBM Setup Utility program (see "Starting the IBM Setup Utility program" on page 99). 2. Select Startup. 3. Select Startup Sequence. See the information displayed on the right side of the screen. 4. Select the sequence of devices for the Primary Startup Sequence, the Automatic Startup Sequence, and the Error Startup Sequence. 5. Select Exit from the IBM Setup Utility menu and then Save Settings. 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. The default setting for HyperThreading is Enabled. However, if you select Set Defaults (HyperThreading is Enabled) and are using an operating system other than Windows XP, your computer performance might be degraded. Therefore, you should always set HyperThreading to disabled unless you are sure your operating system supports hyperthreading. 102 User Guide
