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 G1 system for any reason, you must be sure to reinstall the correct version. Dell recommends performing a peri- odic 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 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 con- figuration, 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 “Using Drivers and Utilities” section of your online System User’s Guide.) You may also need to reinstall your system’s video 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 down- load Windows 95 from a server to client systems, make sure that you have the Windows 95 backup media for the OptiPlex G1 system on your server before downloading.

NOTE: The following procedure applies only to versions of Windows 95 installed by Dell.

If you must reinstall Windows 95 on your computer system, you also need to run the Intel PIIX4e INF Update Installer for Windows 95 immediately after installing the oper- ating system. Doing so enables Windows 95 to detect and configure PCI devices controlled by the integrated 82371EB component.

Before you can perform the update, you must make a diskette 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. Refer to the online System User’s Guide for information about using the Program Diskette Maker.
