(Device drivers are normally included with your operating system software or with the device itself.) See the documentation that accompanied the device for specific installation and configuration instructions. • Always attach external devices while your system and the device are turned off. Next, turn on any external devices before turning on the system (unless the documentation for the device specifies otherwise). For information about individual connectors, see "Jumpers and Connectors" on page 139. For information about enabling, disabling, and configuring I/O ports and connectors, see "Using the System Setup Program" on page 37. About Your System 17
