onnecting External Devices
You can connect various external devices, such as a
mouse and printer, to the I/O ports and connectors on the
computer's back panel. The system BIOS detects the
presence of external devices when you boot or reboot
your system. When connecting external devices to your
computer, 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 connector 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 computer recognize an external
device and direct its operation.
•
Always attach external devices while your computer
is turned off. Then turn on the computer before

turning on any external devices, unless the documen-
tation for the device specifies otherwise. (If the
computer does not seem to recognize the device, try
turning on the device before turning on the computer
to see if this resolves the problem.)
For information about enabling, disabling, or configuring
I/O ports and connectors, see Chapter 4, "Using the Sys-
tem Setup Program," or Chapter 5, "Using the System
Configuration Utility." For detailed descriptions and
illustrations of each port and connector on the I/O panel,
see Appendix B, "I/O Ports and Connectors."

reventing Unauthorized Access
Inside the Computer
To prevent unauthorized access to the inside of the com-
puter, you can lock the left and right computer covers and
hard-disk drives using a key provided with the system
and the keylocks (see Figure 1-2).

hysically Securing the
Computer
The security cable slot lets you attach a commercially
available antitheft device to the computer. Antitheft
devices for personal computers usually include a segment
of metal-stranded cable with an attached locking device
and associated key. To prevent unauthorized removal of
your computer, loop the cable around an immovable
