Selecting a startup device

If your computer does not start up (boot) from a device such as the CD-ROM, diskette, or hard disk as expected, use one of the following procedures to select a startup device.

Selecting a temporary startup device

Use this procedure to startup from any boot device.

Note: Not all CDs, hard disks, and diskettes are startable (bootable).

1.Turn off your computer.

2.Turn on your computer and look for the following prompt on the logo screen:

(To interrupt normal startup, press Enter)

Press Enter when you see the prompt.

3.When the Startup Interrupt Menu displays, press F12.

4.Select the desired startup device from the Startup Device menu and press Enter to begin.

Note: Selecting a startup device from the Startup Device menu does not permanently change the startup sequence.

Changing the startup device sequence

To view or permanently change the configured startup device sequence, do the following:

1.Start the IBM Setup Utility program (see “Starting the IBM Setup Utility program” on page 27).

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 IBM 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. The default setting for HyperThreading is Enabled. However, if you select Set Defaults 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.
