1-6 Dell OptiPlex GXa Mini Tower Systems Reference and Installation Guide
If you are unable to reinstall your software from a tape
backup of the hard-disk drive, you can reinstall the Win-
dows 95 operating system 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. However, if you reinstall the Windows 95 operat-
ing system in this manner, the bus-mastering functionality
of the Windows 95 EIDE driver, which was operative in
your original configuration, will be disabled. (Your sys-
tem will operate without the bus-mastering functionality
with only a small degradation in performance. For infor-
mation 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.
NOTE: If you are a system administrator of corporate
networks and you must download the Windows 95 oper-
ating system from a server to client systems, make sure
that you have the Windows 95 backup media for the Opti-
Plex GXa system on your server before downloading.
I
ntel PIIX4 INF Update Installer for Windows 95 NOTE: The following procedure applies only to versions
of the Microsoft Windows 95 operating system installed
by Dell.
If you must reinstall Windows 95 on your computer sys-
tem, you also need to run the Intel PIIX4 INF Update
Installer for Windows 95 immediately after installing the
operating system. Doing so enables Windows 95 to
detect and configure PCI devices controlled by the inte-
grated 82371AB component.
Before you can perform the update, you must make a dis-
kette copy of the update software from the disk image on
the hard-disk drive. To make the diskette copy, use the
Program Diskette Maker, which is located in the Dell
Accessories folder on your system. Refer to the online
System User’s Guide for information about using the Pro-
gram Diskette Maker.
The following procedure describes how to install the
update:
1. Insert the Windows 95 Intel Support Driver Ver.
A00 diskette into drive A.
2. Click the Start button and click Run.
3. Type a:\setup.exe and press Enter.
4. Click Next on the Welcome Screen.
The license agreement opens in the Notepad applica-
tion program.
5. View the text file and close the Notepad applica-
tion program when you are ready to proceed.
6. Click Yes to continue.
The next dialog box lists the information (.inf) files
on your system that will be revised by the update
software.
7. Click Next to continue.
8. Click OK to start the update.
9. When the update is complete, remove the diskette
from the diskette drive and click OK to restart
your system.
During start-up, the operating system detects new
hardware and the Update Device Driver Wizard
screen appears.
10. Click Next to continue.
The system finds the hardware device driver on the
hard-disk drive and installs it.
11. Click Finish to continue.
The system continues its start-up routine. When
Windows 95 finishes loading, a dialog box appears
and informs you that the system configuration set-
tings have changed and asks if you want to restart
your system.
12. Click OK to restart the system.
