The EPA’s ENERGY STAR
®
Computers program is a joint effort between the EPA and
computer manufacturers to reduce air pollution by promoting energy-efficient com-
puter products. The EPA estimates that use of ENERGY STAR
®
computer products
can save computer users up to two billion dollars annually in electricity costs. In turn,
this reduction in electricity usage can reduce emissions of carbon dioxide, the gas pri-
marily responsible for the greenhouse effect, and sulfur dioxide and nitrogen oxides,
which are the two primary causes of acid rain.
Computer users can also help to reduce electricity usage and its side effects by turn-
ing off their computer systems when they are not in use for extended periods of
time—particularly at night and on weekends.

Your system was configured by Dell to optimize the features of the Windows 95 oper-
ating system. To ensure that all of these features are maintained on your system, you
must use the version of Windows 95 that Dell installed on your hard-disk drive.
Should you need to reinstall Windows 95
on an OptiPlex GX1 or GX1p system
for any
reason, you
must
be sure to reinstall the correct version. Dell recommends perform-
ing a periodic tape backup of the system’s entire hard-disk drive so that, if necessary,
the operating system, drivers, and other software can be reinstalled as originally con-
figured with a minimum of downtime.
If you are unable to reinstall your software from a tape backup of the hard-disk drive,
you can reinstall Windows 95 from the system’s Windows 95 CD that you received
from Dell.
However, if you reinstall Windows 95 in this manner, the bus-mastering
functionality of the Windows 95 EIDE driver, which was operative in your original con-
figuration, will be disabled
. (Your system will operate without the bus-mastering
functionality with only a small degradation in performance. For information on the
advantages of using bus-mastering drivers, see “Bus-Mastering EIDE Drivers” in the
“Using Drivers and Utilities” section of your online
System User’s Guide
.) You may
also need to reinstall your system’s video, audio, and NIC drivers from the diskettes
created from the Dell-installed software on your system.
