vi Lenovo BIOS Windows Management Instrumentation Interface Deployment Guide

Chapter 1. Overview

IT administrators are always looking for easier ways to manage client computer

BIOS settings, which include passwords, hardware settings, and the boot order.

The Lenovo BIOS WMI interface provides asimplified way to change these

settings. Lenovo has developed aBIOS 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 astandard feature in most Windows®operating systems. It

provides apowerful 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.
