NOTES: As an Energy Star Partner, Dell Computer Cor-
poration has determined that this product meets the
Energy Star guidelines for energy efficiency.
Any Dell computer bearing the Energy Star Emblem is
certified to comply with EPA Energy Star requirements
as
configured when shipped by Dell . Any changes you
make to this configuration (such as installing additional
expansion cards or drives) may increase the system’s
power consumption beyond the limits set by the EPA’s
Energy Star Computers program.
Figure 1-3. Energy Star Emblem
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 primarily 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 turning off their computer systems
when they are not in use for extended periods of time—
particularly at night and on weekends.
I
mportant Note to Windows 95
Users
For the Microsoft Windows 95 operating system to work
correctly on your computer system, you
must use the ver-
sion of Windows 95 that Dell installed on your hard-disk
drive.
Should you need to reinstall Windows 95 on an OptiPlex
GX i system for any reason, you must be sure to re-
install the correct version. Dell recommends 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 config-
ured 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 Win-
dows 95 from the system’s Windows 95 backup media
(CD or diskettes) that you received from Dell or created
from the Dell-installed software on your system.
How-
ever, 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 Driv-
ers” in the 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.
NOTE: If you are a system administrator of corporate
networks and you must download Windows 95 from a
server to client systems, make sure that you have the Win-
dows 95 backup media for the OptiPlex GX
i system on
your server before downloading.
