Overview
The Dell™ OptiPlex™ E1 Managed PC is a high-speed, expandable personal computer designed around the Intel
®
Celeron™
microprocessor. The 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 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 Celeron microprocessor that runs at an internal speed of 300 mega- hertz (MHz) and an external bus speed of 66
MHz.
The Intel Celeron microprocessor includes 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.
The Celeron microprocessor has a 16-kilobyte (KB) internal data cache and a 16-KB internal instruction cache, an internal
math coprocessor, and other advanced internal logic.
A keyboard command (<Ctrl><Alt><\>) 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.
System memory that can be increased up to 256 megabytes (MB) by installing 16-, 32-, 64-, or 128-MB nonparity
synchronous dynamic random-access memory (SDRAM) dual in-line memory modules (DIMMs) in the two DIMM sockets on
the system board. See "
Adding Memory " for details.
Self-Monitoring and Analysis Reporting Technology II (SMART II) 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 II-compliant hard-disk
drive in your computer. All hard-disk drives shipped with the OptiPlex E1 system are SMART II-compliant.
A basic input/output system (BIOS), which resides in flash memory and can be upgraded by diskette, or remotely over a
network, if required.
Full compliance with PCI specification 2.1.
Full Plug and Play version 1.0a capability, which greatly simplifies the installation of expansion cards. Plug and Play support
included in the system BIOS allows you to install Plug and Play expansion cards without setting jumpers or switches or
performing other configuration tasks. The ISA Configuration Utility (ICU) allows you to configure existing non-Plug and Play
ISA expansion cards for conflict-free operation. Also, because the system BIOS is stored in flash memory, it can be updated
to support future enhancements to the Plug and Play standard.
Wakeup On LAN capability, which, when enabled in the System Setup program, allows the system to be powered up from a
