Chapter 3. Typical usage

Through WMI, you can configure BIOS settings in the following ways:
• List BIOS settings
• Change BIOS settings
• Change the boot order (sometimes referred to as the startup sequence)
• Load default BIOS settings

Listing current BIOS settings

For a list of all available BIOS settings that can be changed through WMI on a specific computer, use the
Lenovo_BiosSetting class (see "List all BIOS settings on the local computer" on page 17 and "List all BIOS
settings on the remote computer" on page 20 for sample scripts).
See Table 4 "List of available BIOS settings" on page 5 for a list of available BIOS settings.

Changing BIOS settings

To change a BIOS setting, complete the following steps:
1. Identify the BIOS setting you want to change using the Lenovo_BiosSetting class (see "List all BIOS
settings on the local computer" on page 17 and "List all BIOS settings on the remote computer" on
page 20 for sample scripts).
2. Identify the value to which the setting will be changed.
Note: See Table 4 "List of available BIOS settings" on page 5 for a list of available values for a
particular setting.
3. Change the BIOS setting to the desired value using the Lenovo_SetBiosSetting class, then use the
Lenovo_SaveBiosSetting class to save the settings (see "Set a single BIOS setting on the local
computer" on page 18 and "Set a single BIOS setting on a remote computer" on page 20 for sample
scripts).
Note: BIOS settings and values are case sensitive.
After making changes to the BIOS settings, you must reboot the computer before the changes will take effect.

Changing the boot order

To change the boot order, complete the following steps:
1. Determine the current setting for "BootOrder" by using the Lenovo_BiosSetting class (see "List all BIOS
settings on the local computer" on page 17 and "List all BIOS settings on the remote computer" on
page 20 for sample scripts).
2. To set a new boot order, use the Lenovo_SetBiosSetting class, then use the Lenovo_SaveBiosSetting
class to save the settings (see "Set a single BIOS setting on the local computer" on page 18 and "Set a
single BIOS setting on a remote computer" on page 20 for sample scripts). Specify a new boot order
by listing the boot devices in order, separated by colons. Devices that are not specified are excluded
from the boot order. In the following example, the CD drive 0 is the first boot device and hard disk
drive 0 is the second startup device.
