Installing external options
You can connect external options to your computer, such as external speakers, a
printer, or a scanner. For some external options, you must install additional
software in addition to making the physical connection. When installing an
external option, see “Locating connectors on the front of your computer” on page 7
and “Locating connectors on the rear of your computer” on page 8 to identify the
required connector. Then, use the instructions that come with the option to help
you make the connection and install any software or device drivers that are
required for the option.
