System configuration is the process of specifying the devices
and programs that make up a computer system. When you add
or remove optional equipment, or add a second diskette drive,
you must reconfigure the computer to recognize these changes.
Windows 95 and Windows NT automatically recognize all Plug
and Play devices installed. However, if the device is not a Plug
and Play device or is not installed properly, follow these
instructions:
1. Go to the Control Panel.
2. Select the Add New Hardware icon.
3. Follow the instructions on the screen.
The Compaq Deskpro 4000 and 6000 Series of Personal
Computers include features that make it easier to upgrade or
service your computer.
The Quick Release Cover Latches located on the sides of the
computer allow easy removal of the computer cover without the
use of tools or thumbscrews. Slide the cover latches toward the
front of the computer to unlock the cover. Slide the cover
latches toward the back of the computer to secure the cover. The
latches are labeled with locked and unlocked padlock icons to
identify the position of the latches.
