Preface
The purpose of this guide is to explain how to modify BIOS
settings, boot order using Windows Management Instrumentation
(WMI) through the Lenovo client-management interface. This
guide is intended for skilled IT administrators who are familiar
with configuring BIOS settings on computers in their
organizations.
This guide is provided in a ZIP file package that contains this
deployment guide as well as Visual Basic sample scripts to use
when configuring BIOS settings.
This deployment guide is developed for IT professionals to assist
with the unique challenges that they encounter. If you have
suggestions or comments, communicate with your Lenovo®
authorized representative. To learn more about the technologies that
can help you lower the total cost of ownership and to check for
periodic updates to this guide, visit the following Web site:

Chapter 1. Overview
IT administrators are always looking for easier ways to manage
client computer BIOS settings, which include hardware settings,
and the boot order. The Lenovo BIOS WMI interface provides a
simplified way to change these settings. Lenovo has developed a
BIOS interface that can be manipulated through Windows
Management Instrumentation (WMI). The Lenovo BIOS WMI
interface enables IT administrators to make queries on current
BIOS settings, restore settings to their factory defaults, change
single settings, reset or change passwords, and modify the boot
order either at client computers or remotely.

Using Windows Management Instrumentation
WMI is provided as a standard feature in most Windows® operating
systems. It provides a powerful set of functions, such as
query-based information retrieval and event notification, which
enables users to manage both local and remote computers. The
Lenovo BIOS WMI interface extends the capabilities of WMI to
allow management of BIOS settings.
The following illustration shows how WMI can be used to access
Lenovo BIOS settings.

WMI uses Windows Script host (WSH) to interpret scripts. You can
write your scripts in either Windows Visual Basic Scripting Edition
(VBScript) or JavaScript.

Key benefits
The Lenovo BIOS WMI interface provides the following benefits:

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 16 and “List all BIOS settings on a
remote computer” on page 18 for sample scripts).
See Table 3 on page 4 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 16 and “List all BIOS settings on a remote
computer” on page 18 for sample scripts).
2. Identify the value to which the setting will be changed.
Note: See Table 4 on page 4 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 16 and “Set a single BIOS setting on a remote
computer” on page 17 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
@Copyright Lenovo 2010

9

Lenovo_BiosSetting class (see “List all BIOS settings on the local
computer” on page 16 and “List all BIOS settings on the remote
computer” on page 18for 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 16
and “Set a single BIOS setting on a remote computer” on page 17
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/DVD drive is the first boot device and hard
disk drive is the second boot device and so on.
Example: Change primary boot sequence,
Primary Boot Sequence,CD/DVD Drive:Hard Drive:Network
Card:USB Key:USB Floppy:USB Hard Disk

Restoring default settings
To restore default BIOS settings, use the Lenovo_LoadDefaultSettings class,
and then use the Lenovo_SaveBiosSettings class to save the BIOS changes
(see sample scripts).

Changing an existing hardware password
To update a password, specify a password type and format the
password. The format for password parameters is ″pap,abc,def,ascii,us″
with descriptions in Table 5 (see “Set a Administrator password on the
local computer when a Administrator password exists” on page 20 and
“Set a Administrator password on a remote computer when a
Administrator password exists” on page 21 for sample scripts).

Limitations
The following WMI limitations exist for BIOS setup:
·Administrator password, POP,HDP and the item”Hardware Password
Manager” cannot be changed simutaneously during one power cycle. If
you want to change these settings, you must reboot the system after
changing one of them.
·A password cannot be set using this method when one does not already
exist. Passwords can only be updated or cleared.
·When user try to batch update BIOS settings, make sure that the related
item of each item is in correct state, because once one item’s related item is
Disabled or with special setting, this item will be hidden and can not be
updated through WMI. Please reference Table 4 for detail relationship
between items.

Chapter 4. Security
WMI-based administration scripts operating over a remote connection send
data over the network in clear text by default. You can enhance security by
modifying WMI-based administration scripts to establish an encrypted
remote connection as follows:
1.
Set an impersonation level of ″impersonate″
2.
Set an authentication level of ″pktPrivacy″
See Appendix A, “Sample Visual Basic scripts for configuring BIOS
settings,” on page 15 for sample scripts used to implement WMI-based
administration scripts that include these parameters for encryption.

@Copyright Lenovo 2010

Appendix A. Sample Visual Basic scripts for
configuring BIOS settings
The Visual Basic command line scripts in the ZIP file are examples
that you may find helpful when configuring BIOS settings.
The scripts in the ZIP file can be used as-is on Windows XP ,
Windows Vista or Windows 7 to modify BIOS settings on your
Lenovo computer. The scripts can be executed on a command
prompt using the cscript.exe utility. On Windows Vista, you must
run the scripts from an administrator command prompt.
Note: The scripts in this appendix are for reference only. To copy
and paste scripts, use the scripts in the ZIP file. Pay attention to that
symbol “;” is treated as the end of paramter in script, so make sure
each method input paramter in script will end with “;”

Restore default settings
Use the example scripts in the ZIP file as templates to restore default
settings on the local computer.
Syntax: cscript.exe LoadDefaults.vbs
Example: cscript.exe LoadDefaults.vbs
