nergy Star Compliance
Certain configurations of Dell computer systems comply
with the requirements set forth by the Environmental
Protection Agency (EPA) for energy-efficient computers.
If the front panel of your computer bears the Energy Star
Emblem (see Figure 1-4), your original configuration
complied with these requirements and all Energy Star
power management features of the computer are enabled.
To disable or change the operation of these features, you
must change the setting for the Power Management cate-
gory in the System Setup program. For instructions, see
Chapter 2, “Using the System Setup Program,” or the
online System User’s Guide.
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 1-4. 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 Notes to Windows 95
Users
The following subsections apply only to systems running
a Dell-installed Microsoft Windows 95 operating system.
Reinstalling Windows 95
Dell configured your system to optimize the Microsoft
Windows 95 operating system features. 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. In particular, versions of Windows 95
before 4.00.950 B do not contain bus-mastering EIDE
support.
Should you need to reinstall Windows 95 for any reason,
you must be sure to reinstall the correct version. Dell rec-
ommends 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 rein-
stalled 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 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
Windows 95 bus-mastering EIDE driver is installed but
disabled. To enable this driver, see “Bus-Mastering EIDE
Drivers for Windows 95” in the online System User’s
Guide.
You may also need to reinstall other drivers after rein-
stalling Windows 95. See “Using Utilities and Drivers”
in your online System User’s Guide for more information.
NOTE: If you are a network 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 Gn or Gn+
system on your server before downloading.
