Important Note To Windows 95 Users - Dell Precision 400 User Manual

•
Enhanced security features available through the
System Setup program (a setup password, a system
password, a system password lock option, a write-
protect option for diskette drives, and automatic
display of the system's service tag number). In addi-
tion, a customer-definable asset tag number can be
assigned via a software support utility and viewed on
the System Setup screens. For more information, see
Chapter 2, "Using the Software Support Utilities,"
and Chapter 3, "Using the System Setup Program."
•
Advanced power management options that can
reduce the energy consumption of your system. For
more information, see Chapter 3, "Using the System
Setup Program."
•
The ICU, which allows you to configure ISA expan-
sion cards manually. After resources have been
assigned to these cards, the system BIOS can assign
resources to PCI and Plug and Play expansion cards
for a conflict-free configuration. For more informa-
tion, see Chapter 4, "Using the ISA Configuration
Utility."
•
Dell Diagnostics for evaluating the computer's com-
ponents and devices. For information on using the
diagnostics, see the chapter titled "Running the Dell
Diagnostics" in the Diagnostics and Troubleshooting
Guide.
•
Network device drivers for several network operat-
ing systems. These drivers are described in
Chapter 5, "Using the Network Interface
Controller."
•
Desktop Management Interface (DMI) support,
which enables the management of your computer
system. DMI defines the software, interfaces, and
data files that enable your system to determine and
report information about system components.
If your system has a Dell-installed Microsoft
Windows or Microsoft Windows NT operating
system, DMI is already installed on your system's
hard-disk drive. To learn more about DMI, double-
click the Dell DMI Help icon in the Dell DMI folder
from the Start menu.
•
The Dell Inspector utility, which uses DMI support
to display detailed information about the hardware
and software configuration for your system. The
Dell Inspector utility provides you with the informa-
tion you may need if you call Dell for technical
assistance. It also provides you with the information
you may need when you install hardware or software
in your system. The Dell Inspector utility is located
in the Dell Accessories program folder.
If you ordered Dell-installed software with your system,
such as the Microsoft Windows NT or Microsoft Win-
dows 95 operating system, Dell provides a menu that
allows you to make program diskette sets of your Dell-
installed software. A program diskette set is an uninstalled
version of a software package that you can use to reinstall
or reconfigure the software. You can use this same menu
to remove diskette image files (individual files that corre-
spond to each diskette in a program diskette set) to
reclaim space on the computer's hard-disk drive. For
more information on making program diskette sets, see
the online help provided in the Dell DiskMaker program,
which is available in the Dell Accessories program
folder.

mportant Note to Windows 95
Users
Your system was configured by Dell 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 the Windows 95
operating system 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
reinstalled as originally configured, with a minimum of
downtime.
