Chapter 2 Using the Software Support Utilities Your Dell system comes with software support utilities on diskette or on your computer's hard-disk drive. These software support utilities include system utilities, system services, and bus-mastering enhanced integrated drive electronics (EIDE) drivers, all of which are documented in this chapter. For information on the additional software support utilities you received with your system, refer to the following: • Video drivers - See the documentation from the video card manufacturer. (Video drivers support the video graphics requirements of a variety of monitors and application programs running under the Microsoft Windows NT 4.0 or Microsoft Windows 95 operating system.) NOTE: Some video cards provide video drivers only for the Windows NT operating system. • Audio drivers - See Chapter 6, "Using the Inte- grated Audio Controller," of this guide. • Network interface drivers - See Chapter 5, "Using the Network Interface Controller," of this guide. System utilities and services can be used to safeguard your system and to explicitly control certain hardware features. Refer to "System Utilities and Services" found later in this chapter for information about these utilities. Bus-mastering EIDE drivers are provided for the Windows 95 and Windows NT 4.0 operating systems. These drivers can off-load certain functions from the system microprocessor, providing a performance improvement during multithreaded operations (instances where several application programs are running simultaneously). Refer to "Bus-Mastering EIDE Drivers" found later in this chapter for information about these utilities. Dell-Installed Software Support Utilities If no software support diskettes were shipped to you, the system utilities, services, and bus-mastering EIDE drivers are already installed on your hard-disk drive in two different forms: as working utilities, operative immediately, and as diskette images. In case you later need to reinstall the files for any reason, you need to copy the diskette images to a backup diskette (see the next section, "Backing Up the Software Support Utilities"). From the backup diskette, you can install the desired file(s) to a directory on your hard-disk drive. Further instructions for installing the utilities, services, and drivers are provided later in this chapter. Backing Up the Software Support Utilities Dell recommends that you create original diskette copies, or program diskette sets, of your Dell-installed software. You will need these diskettes if you ever want to reconfigure or reinstall your Dell-installed software. To create program diskettes, use the Dell DiskMaker program to create program diskette sets (available through the Dell Accessories program folder). Software Support Utilities on Diskette If you received Dell software support diskettes, the Dell system utilities, services, and bus-mastering EIDE drivers are provided on these diskettes.
