Installing external options

External speakers, a printer, or a scanner can be connected to your computer. 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 8
and “Locating connectors on
the rear of your computer” on page 9
to identify the required connector, and 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.
