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 prima-
rily 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 E1 Mini Tower Managed PC
system for any reason, you
must be sure to reinstall the correct version. Dell recom-
mends performing 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 configured 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
configuration, 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
