Using the Drivers and Utilities CD

In most cases, the CD starts running automatically. If it does not, start Windows Explorer, click your
CD drive directory to display the CD contents, and then double-click the autorcd.exe file. The first
time that you run the CD, it might prompt you to install setup files. Click OK, and follow the
instructions on the screen to continue.

utility (if available). A welcome screen appears.
4 Click Next.
The CD automatically scans your hardware to detect drivers and utilities used by your computer.
5 After the CD completes the hardware scan, you can also detect other drivers and utilities. Under
Search Criteria, select the appropriate categories from the System Model, Operating System, and
Topic drop-down menus.
A link or links appear(s) for the specific drivers and utilities used by your computer.
6 Click the link of a specific driver or utility to display information about the driver or utility that you
want to install.
7 Click the Install button (if present) to begin installing the driver or utility. At the welcome screen,
follow the screen prompts to complete the installation.
If no Install button is present, automatic installation is not an option. For installation instructions,
either see the appropriate instructions in the following subsections, or click Extract, follow the
extracting instructions, and then read the readme file.
If instructed to navigate to the driver files, click the CD directory on the driver information window to
display the files associated with that driver.
