You can connect various external devices, such as a mouse and printer, to the I/O
ports and connectors on the system's back panel. The system BIOS detects the pres-
ence of external devices when you boot or reboot your system. When connecting
external devices to your system, follow these guidelines:
Check the documentation that accompanied the device for specific installation
and configuration instructions.
For example, most devices must be connected to a particular I/O port or connec-
tor to operate properly. Also, external devices like a mouse or printer usually
require you to load software files called device drivers into memory before they will
work. These software drivers help the system recognize an external device and direct
its operation. Device drivers of this type are normally included with your operating sys-
tem software.
Always attach external devices while your system is turned off . Then turn on any
external devices before turning on the system unless the documentation for the device
specifies otherwise. (If the system does not seem to recognize the device, try turning
on the system before turning on the device.)
