Working with Video Memory This section provides information and instructions for installing and removing video memory from the video memory connector on the system board of some models. For some models, you can add video memory to your computer to increase the video performance, resolution, and graphics capabilities. These models have a connector for installing a memory module that provides up to a maximum of 4 MB of video memory. Models without the connector already have 4 MB of video memory. Installing a Video Memory Module Before you begin: Read "Safety Information" on page vii and "Handling Static-Sensitive Devices" on page 52. Read the instructions that come with the new video memory. Turn off the computer and all other connected devices. Disconnect all cables attached to the computer and remove the computer cover (see "Removing the Cover" on page 54). Read "Accessing the System Board" on page 60 to learn the location of parts on the system board. To install a video memory module: 1.
