Chapter 1 Introduction Dell® OptiPlex® Gs and Gs+ low-profile systems are high-speed, expandable personal computers designed around Intel® Pentium® microprocessors. Each system uses a high-performance Peripheral Component Interconnect (PCI) design that allows you to configure the computer system to your initial requirements and then add Dell-supported upgrades as necessary. These systems also support the Industry-Standard Architecture (ISA) bus for older expansion devices. This chapter describes the major hardware and software features of your system, provides information about accessing the online documentation, and tells you where to find help if you need it. System Features Your system offers the following features: • An Intel Pentium microprocessor. The following microprocessor options are available: - An Intel Pentium microprocessor with an internal speed of 133 megahertz (MHz) and an external speed of 66 MHz - An Intel Pentium microprocessor with an internal speed of 166 MHz and an external speed of 66 MHz - An Intel Pentium microprocessor with an internal speed of 200 MHz and an external speed of 66 MHz The Pentium microprocessor has an 8-kilobyte (KB) internal data cache and an 8-KB internal instruction cache, an internal math coprocessor, and other advanced internal logic. The key combination lets you switch between the microprocessor's rated speed and a slower compatibility speed. NOTE: The key combination is not available under the Microsoft® Windows NT ® and IBM® OS/2® operating systems. • An integrated cache with 256 KB of static random- access memory (SRAM). Cache memory enhances the speed of many microprocessor operations by storing the most recently accessed contents of system memory. • System memory that can be increased up to 128 megabytes (MB) by installing pairs of 4-, 8-, 16-, or 32-MB extended-data out (EDO) single inline memory modules (SIMMs) in the four SIMM sockets on the system board. EDO SIMMs offer improved performance by using a shorter page-mode cycle time while accessing data within a single page of memory. See "Adding Memory" in Chapter 6 for details. • Self-Monitoring Analysis Reporting Technology (SMART) support, which warns you at system start-up if your hard-disk drive has become unreliable. To take advantage of this technology, you must have a SMART-compliant hard-disk drive in your computer. All the hard-disk drives shipped with the Dell OptiPlex Gs and Gs+ systems are SMARTcompliant. • Full compliance with PCI specification 2.0. • Full Plug and Play version 1.0a capability, which greatly simplifies the installation of expansion cards. Plug and Play support included in the system's basic input/output system (BIOS) allows you to install Plug and Play expansion cards without setting jumpers or switches or performing other configuration Introduction 1-1
