OptiPlex

Gn and Gn+ low-profile systems are
high-speed, expandable personal computers designed
around Intel
®
Pentium
®
microprocessors. Each system
uses a high-performance Peripheral Component Inter-
connect (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.
S
ystem Features
Your system offers the following features:
•
An Intel Pentium microprocessor with MMX
™
technology that runs at an internal speed of 166, 200,
or 233 megahertz (MHz) and an external speed of
66 MHz.
The Pentium microprocessor with MMX technology
has a 16-kilobyte (KB) internal data cache and a
16-KB internal instruction cache, an internal math
coprocessor, and other advanced internal logic.
•
The <Ctrl><Alt><\> key combination lets you
switch between the microprocessor’s rated speed and
a slower compatibility speed.
NOTE: The <Ctrl><Alt><\> key combination is not
available under the Microsoft
®
Windows NT
®
and
IBM
®
OS/2
®
operating systems.
•
A cache with 512 KB of pipelined-burst 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 supports both parity and non-
parity extended-data out (EDO) dual in-line memory
modules (DIMMs). System memory can be increased
up to 256 megabyte (MB) by installing any combina-
tion of 16-, 32-, 64-, or 128-MB DIMMs in the two
DIMM sockets on the system board. The use of non-
parity EDO DIMMs is recommended. 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 com-
puter. All hard-disk drives shipped with OptiPlex Gn
or Gn+ systems are SMART-compliant.
•
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’s basic
input/output system (BIOS) allows you to install
Plug and Play expansion cards without setting
jumpers 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.
NOTE: The system’s BIOS resides in flash memory
and can be updated by diskette 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
turned on from a server management console.
Wakeup On LAN capability also allows remote com-
puter setup, software downloading and installation,
file updates, and asset tracking after hours and on
