(16-bit) expansion slots; the passive option includes two PCI expansion slots, two ISA expansion slots, and one shared PCI/ISA expansion
slot.
lA 64-bit accelerated graphics port (AGP) video subsystem, which includes the ATI 3D Rage Pro super video graphics array (SVGA) video
controller. On the Dell OptiPlex GX1, this video subsystem contains 4 MB (upgradable to 8 MB) of synchronous graphics random-access
memory(SGRAM)videomemory;theDellOptiPlexGX1pcomeswith8MBofSGRAMvideomemory.Maximumresolutionsare1600×

resolutions, 16.7 million colors are available for true-color graphics using a 32-bits per pixel (bpp) format. True-color provides higher
performance, but uses more graphics memory. Table 1 lists the video memory requirements for the Microsoft Windows®95, Windows 98,
and Windows NT 4.0 operating systems.
Table 1. Video Memory Requirements
2X AGP provides a dedicated bus from the video subsystem to the system chip set. AGP-based video subsystems have two significant
performance advantages over PCI-based video subsystems:
- The AGP bus reduces bandwidth requirements of the PCI bus, improving overall system performance.
- The AGP bus allows a 3D video subsystem to execute directly from main memory.
lA diskette/tape drive interface, which supports a 3.5-inch diskette drive and, optionally, a second diskette drive or tape drive.
lEnhanced integrated drive electronics (EIDE) support. The primary and secondary interface are both located on the PCI bus to provide
faster data throughput. Each interface supports high-capacity EIDE drives, as well as devices such as ATA 33 hard-disk drives, EIDE CD-
ROM drives, and EIDE tape drives.
lTwo high-performance serial ports and one bidirectional parallel port for connecting external devices. The parallel port is fully Enhanced
Capabilities Port (ECP)-compliant.
lA Personal System/2 (PS/2)-style keyboard port and a PS/2-compatible mouse port.
lAn optional integrated, 10/100-megabit-per-second (Mbps) 3Com®PCI 3C905B-TX Ethernet network interface controller (NIC). The NIC is
configured using software on the Dell ResourceCD.
lA 16-bit, integrated Plug and Play Crystal CS4236B audio controller that provides all the sound functions of the Sound Blaster Pro expansion
card. For information, see your online System User's Guide.
Software Features
The following software is included with your Dell computer system:
lSystem utilities that safeguard your system and enhance the operation of its features. More information is available on the Dell
ResourceCD.
lVideo drivers for displaying many popular application programs in high-resolution modes. More information is available on the Dell
ResourceCD.
lAudio drivers for enabling the sound functions on the expansion sound card. More information is available on the Dell ResourceCD.
lBus-mastering EIDE drivers to improve performance by off-loading certain functions from the microprocessor during multithreaded operation
(when several applications are running simultaneously). More information is available on the Dell ResourceCD.
lThe System Setup program for quickly viewing and changing the system configuration information for your system. For more information on
this program, see "Using the System Setup Program."
lEnhanced security features (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) available through the System Setup program. In addition, 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 your online System User's Guide and "Using the System Setup Program."
lAdvanced power management options that can reduce the energy consumption of your system. For more information, see "Using the
System Setup Program."
lThe ICU, which tells you how to configure ISA expansion 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 information, see "Using the
ISA Configuration Utility"
lDell Diagnostics for evaluating the computer's components and devices. For information on using the diagnostics, see the chapter titled
"Running the Dell Diagnostics" in the Diagnostics and Troubleshooting Guide.
lNetwork device drivers for several network operating systems. More information is available on the Dell ResourceCD.
lDesktop Management Interface (DMI) support, which enables the management of your computer system's software and hardware. DMI
defines the software, interfaces, and data files that enable your system to determine and report information about system components.
