Safety Instructions
U
se the following safety guidelines to he lp protect
your computer system from potential damage and to
ensure your own personal safety.
W
hen Using Your Computer
System
As you use your computer system, observe the fo llow ing
safety guidelines:
•
To help avoid damaging your computer, be sure the
voltage selection switch on the power supply is set to
match the alternating current (AC) power available
at your location:
— 115 volts (V)/60 hertz (Hz) in most of North and
South America and some Far Eastern countries
such as Japan, South Korea, and Taiwan
— 230 V/50 Hz in most of Europe, the Middle
East, and the Far East
Also be sure your monitor and attached peripherals
are electrically rated to operate with the AC power
available in your location.
•
To help avoid possible damage to the system board,
wait 5 seconds after turning off the system before
removing a component from the system bo ard or d isconnecting a peripheral device from the computer.
•
To help prevent electric shock, plug the computer
and peripheral power cables into properly grounded
power sources. These cables are equipped with
3-prong plugs to help ensure proper grounding. Do
not use adapter plugs or remove the groundin g prong
from a cable. If you must use an extension cable, use
a 3-wire cable with properly grounded plugs.
•
To help protect your computer system from sudden,
transient increases and decreases in electrical power,
use a surge suppressor, line conditioner, or uninterruptible power su ppl y.
•
Be sure nothing r ests on your compu t er system’s
cables and that the cables are not located where they
can be stepped on or tripped over.
•
Do not spill food or liquids on your computer. If the
computer gets we t, consult your Diagnostics and
Troubleshooting Guide.
•
Do not push any objects into the openings of your
computer. Doing so can cause fire or electric shock
by shorting out interior components.
•
Keep your computer away from radiators and heat
sources. Also, do not block cooling vents. Avoid
placing loose papers underneath yo ur computer; do
not place your computer in a closed-in wall unit or
on a bed, sofa , or rug.
E
rgonomic Computing Habits
WARNING: Improper or prolonged keyboard use
may result in injury.
For comfort and efficiency, observe the following ergonomic guidelines when setting u p and using your
computer system:
•
Position your system so that the monitor and keyboard are directly in front of you as you work.
Special shelves are available (from Dell and other
sources) to help you correctly po sition your
keyboard.
v
•
Set the monitor at a comfortable viewing distance
(usually 510 to 610 millimeters [20 to 24 inches]
from your eyes).
•
Make sure the monitor screen is at eye level or
slightly lower when you are sitting in front of the
monitor.
•
Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting around you (such as
overhead lights, desk lamps, and the curtains or
blinds on nearby windows) to minimize reflections
and glare on the monitor screen.
•
Use a chair that provides good lower back support.
•
Keep your forearms horizontal with your wrists in a
neutral, comfortable position while using the keyboard or mouse.
monitor screen at or below eye level
wrists relaxed and flat
•
Always leave space to rest your hands while using
the keyboard or mouse.
•
Let your upper arms hang naturally at your sides.
•
Sit erect, with your feet resting on the floor and your
thighs level.
•
When sitting, make sure the weight of your legs is on
your feet and not on the front of your chair seat.
Adjust your chair’s height or use a footrest, if necessary, to maintain proper posture.
•
Vary y our wor k activ iti es. Try to or gan ize y our work
so that you do not have to type for extended periods
of time. When you stop typing, try to do things that
use both hands.

W
hen Working Inside Your
Computer
Before you remove the computer cover, perform the following steps in the sequence indicated.
Handle components and cards with care. Don’t touch
•
the components or contacts on a card. Hold a card by
its edges or by its metal mounting bracket. Hold a
component such as a microprocessor chip by its
edges, not by its pins.
CAUTIONS: Do not attempt to service the computer system yourself, except as explained in this
guide and elsewhere in Dell documentation. Always
follow installation and service instructions closely.
To help avoid possible damage to the system board,
wait 5 seconds after turning off the system before
removing a component from the system board or
disconnecting a peripheral device from the
computer.
1. Turn off your computer and any peripherals.
2. Disconnect your computer and peripherals from
their power sources. Also, disconnect any telephone or telecommunication lines from the
computer.
Doing so reduces the potential for personal injury or
shock.
3. Touch an unpainted metal surface on the chassis,
such as the metal around the card-slot openings at
the back of the computer, before touching anything inside your computer.
While you work, periodically touch an unpainted
metal surface on the computer chassis to dissipate
any static electricity that might harm internal
components.
In addition, take note of these safety guidelines when
appropriate:
When you disconnect a cable, pull on its connector
•
or on its strain-relief loop, not on the cable itself.
Some cables have a connector with locking tabs; if
you are disconnecting this type of cable, press in on
the locking tabs before disconnecting the cable. As
you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before
you connect a cable, make sure both connectors are
correctly oriented and aligned.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside
your computer . To prevent static damage, di schar ge static
electricity from your body before you touch any of your
computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal
surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any
static charge your body may have accumulated.
In addition to the preceding precautions, you can also
take the following steps to prevent damage from electrostatic discharge (ESD):
When unpacking a static-sensitive component from
•
its shipping carton, do not remove the component
from the antistatic packing material until you are
ready to install the component in your computer. Just
before unwrapping the antistatic packaging, be sure
to discharge static electricity from your body.
When transporting a sensitive component, first place
•
it in an antistatic container or packaging.
Handle all sensitive components in a static-safe area.
•
If possible, use antistatic floor pads and workbench
pads.
The following caution may appear throughout this document to remind you of these precautions:
CAUTION: See “Protecting Against Electrostatic
Discharge” in the safety instructions at the front of
this guide.

Introduction
T
he Dell Dimension™ XPS H233 computer system is a
high-speed personal computer designed around an Intel
microprocessor with MMX
combines high-performance Peripheral C omponent Inte rconnect (PCI) design with Industry-Standard Architecture
(ISA) design, allowing a wide range of initial configurations and upgrade possibilit ie s.
This chapter describes the major hardware and software
features of your computer, provides information about
accessing the online documentation, and tells you how to
obtain help if you need it.
S
ystem Features
Your Dell® computer offers the following features:
•
An Intel microprocessor that runs at an internal
speed of 233 megahertz (MHz) and an external
speed of 66 MHz.
The Intel microprocessor in your computer 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.
•
A secondary cache of 512 kilobytes (KB) of static
random-access memory (SRAM) is included within
the single-edge contact (SEC) cartridge, which also
contains the microprocessor. Math coprocessor functionality is internal to the microprocessor.
™
technology. This system
®
•
A high-spee d, high-resol ution PCI video c ard that
takes advantage of the computer’s local bus.
(Documentation from the video card manufacturer is
included with your system.)
•
Memory that can be increased up to 128 megabytes
(MB) by installing two or four 16- or 32-MB
extended-data out (EDO) single in-line memory
modules (SIMMs) in the four SIMM sockets on the
system board. EDO memory devices offer improved
performance over fast-page-mode devices because
they extend the time that data is held after a read
cycle ends. This extension allows the next read cycle
to begin while the data is still being latched from the
previous read cycle.
The system provides error correction code (ECC)
capability whenever parity SIMMs are used. The
system’s ECC capability corrects all single-bit memory errors and detects all multibit memory errors. If
you mix parity and nonparity SIMMs, the system
does not provide ECC capability.
•
Full Plug and Play capability , which can greatly simplify the installation of expansion cards. Plug and
Play support included in the system basic input/
output system (BIOS) allows you to ins tall Plug and
Play expansion cards without setting jumpers or
switches or performing other configuration tasks.
Also, because the system BIOS is stored in flash
memory, it can be updated to support future
enhancements to the Plug and Play standard.
The system board includes the followin g built-in
features:
•
Three 32-bit PCI expansion slo ts, through which you
can connect high-speed PCI peripherals to the PCI
bus—greatly increasing their input/output (I/O)
speeds over the speeds attainable using the ISA bus.
Introduction 1-1
•
Two 16-bit ISA expansion slots.
•
One shared PCI/ISA expansion slot containing both
a PCI and an ISA expansion-card connector, only
one of which can be used at any given time.
•
An integrated diskette drive interface.
•
Enhanced integrated drive electronics (EIDE) support. Both EIDE channels are located on the PCI bus
to provide faster throughput. The primary EIDE
channel supports up to two extremely high-capacity
EIDE hard-disk drives, while the secondary EIDE
channel supports up to two EIDE CD-ROM drives
and/or EIDE tape drives.
•
One high-performance serial port and one bidirectional parallel port for connecting external devices.
The Parallel Port Type category in the system setup
program can be used to set the parallel port for AT,
Personal System/2 (PS/2), Extended Capabilities
Port (ECP), or Enhanced Parallel Port (EPP) mode.
NOTE: Options that use ECP mode may come with
special drivers that must be installed to use this
mode.
•
Two Universal Serial Bus (USB) ports, which can
simplify connecting peripheral devices such as Keyboards, mice, printers, and computer speakers, if
available. The USB connectors on your computer’s
back panel provide a single connection point for
multiple USB-compliant devices. USB-compliant
devices can also be connected and disconnected
while the system is running.
•
A PS/2-style keyboard port and a PS/2-compatible
mouse port.
The following software is included with your Dell computer system:
