Dell OptiPlex GX1 and GX1p midsize Managed PC systems are high-speed, expandable personal
computers designed around the Intel® Pentium® II and Pentium III microprocessors. Each computer 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 section 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 II or Pentium III microprocessor.

The Intel Pentium II and Pentium III microprocessors include MMX™ technology designed to handle
complex multimedia and communications software. This microprocessor incorporates new instructions
and data types as well as a technique called single instruction, multiple data (SIMD) that allows the
microprocessor to process multiple data elements in parallel, thereby improving overall system
performance.

A keyboard command (<\>) that lets you switch between the microprocessor's rated speed
and a slower compatibility speed.

NOTE: This keyboard command is not available under the Microsoft® Windows NT® and IBM®
OS/2® operating systems.
