Using this snapshot, you can view and compare the changes in the computer configuration after you install an option. Also, if you have problems configuring the option after it is installed, ConfigSafe allows you to restore the configuration to the previous settings. If you have preinstalled software, ConfigSafe took a snapshot of the initial configuration of your computer when you started your computer for the first time. You might be able to use this snapshot to restore the configuration to the initial settings. ConfigSafe is a part of the preinstalled software in your computer. For more information, see About Your Software. If you have a desktop model, continue with "Installing options in the desktop model."
