CAUTION: Safety Instructions

Use the following safety guidelines to help ensure your own personal safety and to help protect
your computer and working environment from potential damage.

General

• Do not attempt to service the computer yourself unless you are a trained service
technician. Always follow installation instructions closely.

• To help prevent electric shock, plug the computer and device power cables into properly
grounded electrical outlets. These cables are equipped with 3-prong plugs to help ensure
proper grounding. Do not use adapter plugs or remove the grounding prong from a cable.
If you must use an extension cable, use a 3-wire cable with properly grounded plugs.

• To help avoid the potential hazard of electric shock, do not use your computer during an
electrical storm.

• To help avoid the potential hazard of electric shock, do not connect or disconnect any
cables or perform maintenance or reconfiguration of this product during an electrical
storm.

• If your computer includes a modem, the cable used with the modem should be
manufactured with a minimum wire size of 26 American wire gauge (AWG) and an FCC­compliant RJ-11 modular plug.

• Before you clean your computer, disconnect the computer from the electrical outlet.
Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol
cleaners, which may contain flammable substances.

• To help avoid possible damage to the system board, wait 5 seconds after turning off the
computer before disconnecting a device from the computer.

9

CAUTION: Safety Instructions (continued)

• To avoid shorting out your computer when disconnecting a network cable, first unplug
the cable from the network adapter on the back of your computer, and then from the
network jack. When reconnecting a network cable to your computer, first plug the cable
into the network jack, and then into the network adapter.

• To help protect your computer from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply
(UPS).

• Ensure that nothing rests on your computer’s cables and that the cables are not located

www.dell.com | support.dell.com

where they can be stepped on or tripped over.

• 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 your computer; do not place your computer
in a closed-in wall unit or on a bed, sofa, or rug.

• Do not spill food or liquids on your computer. If the computer gets wet, consult

"Repairing a Wet Computer."

• Do not use your computer during an electrical storm unless the AC adapter cable has
been disconnected from the electrical outlet.

• When you use the AC adapter to run the computer or to charge the battery, place the AC
adapter in a ventilated area, such as a desk top or on the floor.

• The AC adapter may become hot during normal operation of your computer. Use care
when handling the adapter during or immediately after operation.

10

When Using Your Computer

As you use your computer, observe the following safe-handling guidelines.

CAUTION: Do not operate your computer with any cover(s) (including computer

covers, bezels, filler brackets, front-panel inserts, and so on) removed.

• Your computer is equipped with one of the following:

– A fixed-voltage power supply — Computers with a fixed-voltage power supply do not

have a voltage selection switch on the back panel and operate at only one voltage (see
the regulatory label on the outside of the computer for its operating voltage).

– An auto-sensing voltage circuit — Computers with an auto-sensing voltage circuit do

not have a voltage selection switch on the back panel and automatically detect the
correct operating voltage.

– A manual voltage selection switch — Computers with a voltage selection switch on

the back panel must be manually set to operate at the correct operating voltage.

NOTICE: To help avoid damaging a computer with a manual voltage selection switch, set the

switch for the voltage that most closely matches the AC power available in your location. For Japan,
the voltage selection switch must be set to the 115-V position even though the AC power available in
Japan is 100 V. Also, ensure that your monitor and attached devices are electrically rated to
operate with the AC power available in your location.

• Before working inside the computer, unplug the computer to help prevent electric shock
or system board damage. Certain system board components continue to receive power
any time the computer is connected to AC power.

When Using Your Computer (continued)

When Working Inside Your Computer

Before you open the computer cover, perform the following steps in the sequence indicated.

CAUTION: Do not attempt to service the computer yourself, except as explained in

your online Dell™ documentation or in instructions otherwise provided to you by
Dell. Always follow installation and service instructions closely.

NOTICE: To help avoid possible damage to the system board, wait 5 seconds after turning off the

computer before removing a component from the system board or disconnecting a device from the
computer.

1

www.dell.com | support.dell.com

Perform an orderly computer shutdown using the operating system menu.

2 Turn off your computer and any devices connected to the computer.

3 Ground yourself by touching 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.

4 Disconnect your computer and devices, including the monitor, from their electrical

outlets. Also, disconnect any telephone or telecommunication lines from the computer.

Doing so reduces the potential for personal injury or shock.

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, ensure that both connectors are correctly oriented and
aligned.

12

When Using Your Computer (continued)

• Handle components and cards with care. Do not 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.

CAUTION: There is a danger of a new battery exploding if it is incorrectly installed.

Replace the battery only with the same or equivalent type recommended by the
manufacturer. Do not dispose of the battery along with household waste. Contact
your local waste disposal agency for the address of the nearest battery deposit site.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your computer. To prevent static
damage, discharge 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.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

• Do not remove components from their antistatic packing material until you are ready to
install the component in your computer. Just before unwrapping the antistatic packaging,
discharge static electricity from your body.

• When transporting an electrostatic sensitive component, first place it in an antistatic
container or packaging.

Connecting Devices

When you connect external devices to your computer's back panel, follow
these guidelines:

• Check the documentation that accompanied the device for specific

installation and configuration instructions.

For example, you must connect most devices to a particular
input/output (I/O) connector to operate properly. Also, external
devices like a mouse or printer usually require you to load device
drivers into computer memory before they will work.

• Always attach external devices while your computer is turned off. Then

turn on the computer before turning on any external devices, unless
the documentation for the device specifies otherwise. (If the computer
does not seem to recognize the device, try turning on the device before
turning on the computer.)

About Your Computer 29

NOTICE: When you disconnect external devices from the back of the

computer, wait 10 to 20 seconds after turning off the computer before you
disconnect any devices to avoid possible damage to the system board.

Parallel Connector

This is used to connect printers. Default designation is LPT1.

NOTE: The integrated

parallel connector is
automatically disabled if
the computer detects an
installed expansion card

www.dell.com | support.dell.com

containing a parallel
connector configured to
the same address as
specified in “Additional

System Setup Options.”

NOTE: USB mice only

wakes the computer from
the S1 (standby) and S3
(suspend to RAM) states
with a click.

Mouse Connector

Turn off the computer and any attached devices before connecting a mouse
to the computer. If your computer uses Microsoft Windows
Windows NT 4.0, Dell installed the necessary mouse drivers on your hard
drive.

2000 or

USB Connectors

These are used to attach USB-compliant devices such as keyboards, mice,
printers, and computer speakers to your computer.

Integrated Network Adapter Connector

The network adapter, which includes a Remote Wake Up feature, has the
following lights:

• A yellow network activity light flashes when the computer is

transmitting or receiving network data. (A high volume of network
traffic may make this light appear to be in a steady “on” state.)

• A dual-colored link integrity light, which is green when a good

connection exists between a 10-megabit per second (Mbps) network
and the computer, or is orange when a good connection exists between
a 100-Mbps network and the computer. When the light is off, the
computer is not detecting a physical connection to the network.

30 About Your Computer

Network Cable Requirements

The network adapter connector attaches an unshielded twisted pair (UTP)
Ethernet cable to your computer. Press one end of the UTP cable to an RJ45
jack wall plate or to an RJ45 port on a UTP concentrator or hub, depending
on your network configuration, and press the other end of the UTP cable
into the network adapter connector until the cable snaps securely into place.

Dell recommends the use of Category 5 wiring and connectors for our
customers’ networks.

Line-In Jack

This jack is used to attach record/playback devices such as cassette players,
CD players, and VCRs. Connect the line-out cable from any of these
devices to the line-in jack.

Line-Out Jack

This jack is used to attach computer speakers. This jack is amplified, so
speakers with integrated amplifiers are not required. Connect the audio
cable from the speakers to this jack.

Microphone Jack

This jack is used to attach a standard personal computer microphone.
Connect the audio cable from the microphone to the microphone jack.

Video Connector

This connector is used to attach a video graphics array (VGA)-compatible
monitor to your computer.

Serial Connectors

Default port designations: COM1 for port 1 and COM2 for port 2. You can
reassign the serial connector’s designation if you add an expansion card
containing a serial connector using this designation.

If you set the computer’s serial connectors to Auto in system setup and add
an expansion card containing a serial connector configured to a specific
designation, the computer automatically maps (assigns) the integrated
ports to the appropriate COM setting as necessary.

Before you add a card with a serial connector, check the documentation that
accompanied your software to make sure that the software can be mapped
to the new COM port designation.

Keyboard Connector

Attach the keyboard cable to the 6-pin connector on the back panel.

LegacySelect Technology Control

LegacySelect technology control permits the deployment of legacy full,
legacy reduced, or legacy free solutions based on a common platform with
common hard drive images and common help desk procedures. Control is
provided to the administrator through the system setup program, Dell
OpenManage™ IT Assistant, or Dell custom factory integration.

LegacySelect allows the administrator to electronically activate or
deactivate specific connectors and media devices including: serial and USB
connectors, parallel connector, floppy drive, PCI slots, and PS/2 mouse.
When the connectors and media devices are deactivated, resources that
they might have used are available. Any changes that are made will take
place after you reboot the computer.

Manageability

Dell OpenManage™ IT Assistant

Dell OpenManage IT Assistant is the premier Dell™ systems management
application for configuring, managing, and monitoring computers and other
devices on a corporate network. IT Assistant employs the latest remote
management technology to provide asset management, configuration
management, event (alert) management, and security management for
systems equipped with industry-standard management software. Software
of this type is called system management instrumentation.

40 Advanced Features

IT Assistant supports instrumentation that conforms to the following
industry standards:

• Simple Network Management Protocol (SNMP)

• Desktop Management Interface (DMI)

• Common Information Model (CIM)

The instrumentation available for your computer is Dell OpenManage
Client instrumentation, which is based on DMI and CIM. For more
information on IT Assistant, see the Dell OpenManage IT Assistant User’s
Guide available on the Dell website.

Dell OpenManage Client Instrumentation

Dell OpenManage Client Instrumentation is software that enables remote
management application programs such as IT Assistant to do the following:

• Access information about your computer, such as how many processors

it has and what operating system it is running

• Monitor the status of your computer, such as listening for thermal

alerts from temperature probes or hard drive failure alerts from storage
devices

• Change the state of your computer, such as updating its BIOS or

shutting it down remotely

Dell OpenManage Client Instrumentation can be installed on computers
like yours, which, when set up on a network with IT Assistant, are called
managed systems. For more information about Dell OpenManage Client
Instrumentation, see the Dell OpenManage Client Instrumentation User’s
Guide available on the Dell website.

Security

The computer provides the following methods of physically securing the
chassis:

• Chassis Intrusion Detection

• Padlock Ring and Security Cable Slot

Chassis Intrusion Detection

The chassis intrusion monitor can detect when the chassis is opened. The
Chassis Intrusion option in system setup displays the status of the monitor.

1 Enter system setup.

2 Press the down-arrow keys to move to the System Security option.

3 Press <Enter> to access the System Security option's pop-up menu.

4 Press the down-arrow keys to move to the Chassis Intrusion option.

5 Press the spacebar to select an option setting.

Advanced Features 41

Option settings:

• Enabled — When the computer cover is opened with this setting, a

DMI event is generated, the setting changes to Detected, and the
following message appears during the boot routine at the next
computer start-up:

Alert! Cover was previously removed.

To reset the Detected setting, enter system setup during the
computer's power-on self-test (POST). In the Chassis Intrusion
option, press the left- or right-arrow key to select Reset, and then
choose Enabled, Enabled-Silent, or Disabled.

www.dell.com | support.dell.com

• Enabled-Silent (default) — When the computer cover is opened with

this setting, a DMI event is generated and the setting changes to
Detected, but the alert message does not appear during the boot
sequence at the next computer start-up.

• Disabled — No intrusion monitoring occurs and no messages appear.

NOTE: When the setup password is enabled, you must know the setup

password before you can reset the Chassis Intrusion option.

Padlock Ring and Security Cable Slot

Use one of the following methods to secure your computer:

• Use a padlock alone or a padlock and looped security cable with the
padlock ring.

A padlock alone prevents the computer from being opened.

A security cable looped around a stationary object and used in
conjunction with the padlock can help prevent the unauthorized
movement of the computer.

• Attach a commercially available antitheft device to the security cable
slot on the back of the computer to prevent the unauthorized

movement of the computer.

Antitheft devices usually include a segment of metal-stranded cable
with an attached locking device and key. Dell recommends that you
use a Kensington lock. For instructions on installing this kind of
antitheft device, see the documentation that accompanied the device.

42 Advanced Features

Password Protection

The computer provides two types of password protection:

• System Password

• Setup Password

System Password

System passwords allow only those who know the password to have full use
of the computer. Your Dell computer does not have the system password
feature enabled when you receive it.

NOTICE: Although passwords provide security for the data on your computer,

they are not foolproof. If your data requires more security, it is your
responsibility to obtain and use additional forms of protection, such as data
encryption programs.

NOTICE: If you leave your computer running and unattended without having

a system password assigned, or if you leave your computer unlocked so that
someone can disable the password by changing a jumper setting, anyone can
access the data stored on your hard drive.

System Password settings in system setup:

• Enabled — a system password is assigned

• Disabled — system password feature is disabled by a jumper setting on

the system board

NOTE: Before you

purchase an antitheft
device, make sure it
works with the security
cable slot on your
computer.

• Not Enabled — no system password is assigned and the password

jumper on the system board is in the enabled position (its default
setting)

Assigning a System Password

1 Verify that Password Status is set to Unlocked.

2 Highlight System Password and then press the left- or right-arrow key.

The option heading changes to Enter Pass word, followed by an empty
32-character field in square brackets.

3 Type your new system password.

You can use up to 32 characters.

NOTE: You cannot

change or enter a new
system password if either
of these options is
displayed.

NOTE: You can only

assign a system password
when System Password is
set to Not Enabled.

Advanced Features 43

As you press each character key (or the spacebar for a blank space), a
placeholder appears in the field. The password assignment operation
recognizes keys by their location on the keyboard, without
distinguishing between lowercase and uppercase characters. For
example, if you have an M in your password, the computer recognizes
either M or m as correct.

Certain key combinations are not valid. If you enter one of these
combinations, the speaker emits a beep.

To erase a character when entering your password, press <Backspace>
or the left-arrow key.

NOTE: To escape from

www.dell.com | support.dell.com

the field without assigning
a system password, press
<Tab> or the
<Shift><Tab>
combination to move to
another field, or press
<Esc> at any time prior
to completing step 5.

Press <Enter>.

4

If the new system password is less than 32 characters, the whole field
fills with placeholders. Then the option heading changes to Ver if y
Pass word, followed by another empty 32-character field in square
brackets.

5 To confirm your password, type it a second time and press <Enter>.

The password setting changes to Enabled. Your system password is
now set; you can exit system setup and begin using your computer.
Password protection takes effect when you reboot the computer by
turning the computer off and then on again.

Using Your System Password

When you turn on your computer, or when you reboot the computer by
pressing the <Ctrl><Alt><Del> combination, the following prompt
appears on the screen when Password Status is set to Unlocked:

Type in the password and

- press <ENTER> to leave password security enabled.

- press <CTRL><ENTER> to disable password security.
Enter password:

If Password Status is set to Locked, the following prompt appears:

Type the password and press <Enter>.

NOTE: If you have

assigned a setup
password, the computer
accepts your setup
password as an alternate
system password.

44 Advanced Features

If you enter a wrong or incomplete system password, the following message
appears on the screen:

** Incorrect password. **
Enter password:

If you again enter an incorrect or incomplete system password, the same
message appears on the screen. The third and subsequent times you enter
an incorrect or incomplete system password, the computer displays the
following message:

** Incorrect password. **
Number of unsuccessful password attempts: 3
System halted! Must power down.

Even after your computer is turned off and on, the previous message is
displayed each time an incorrect or incomplete system password is entered.

Deleting or Changing an Existing System Password

To delete or change an existing system password, perform the following
steps:

1 Enter system setup program, and verify that Password Status is set to

Unlocked.

2 Reboot your computer to force it to prompt you for a system password.

3 When prompted, type the system password.

4 Press <Ctrl><Enter> to disable the existing system password,

instead of pressing <Enter> to continue with the normal operation of
your computer.

5 Confirm that Not Enabled is displayed for the System Password

option.

If Not Enabled appears in the System Password option, the system
password has been deleted. If you want to assign a new password,
continue to step 6. If Not Enabled is not displayed for the System
Password option, press <Alt><B> to reboot the computer, and then
repeat steps 3 through 5.

6 To assign anew password, follow the procedure in “Assigning a System

Password.”

NOTE: You can use

Password Status in
conjunction with System
Password and Setup
Password to further
protect your computer
from unauthorized
changes.

Setup Password

Setup passwords allow only those who know the password to have full use of
system setup. Your Dell computer does not have the setup password feature
enabled when you receive it.

Setup Password options in system setup:

Advanced Features 45

www.dell.com | support.dell.com

NOTE: The setup

password can be the same
as the system password.

• Enabled — does not allow assignment of setup passwords; users must

enter a setup password to make changes to system setup

• Not Enabled — allows assignment of setup passwords; password

feature is enabled but no password is assigned

Assigning a Setup Password

54 Advanced Features

– Mouse Port enables or disables the computer's integrated Personal

System/2 (PS/2)-compatible mouse port. Disabling the mouse
allows an expansion card to use interrupt request (IRQ)12.This
setting is used to control the use of this legacy device.

– Serial Port 1 and Serial Port 2 configure the computer's integrated

serial connectors. You can set these options to Auto (the default)
to automatically configure a connector, to a particular designation
(COM1 or COM3 for Serial Port 1; COM2 or COM4 for Serial
Port 2), or to Off to control the use of this legacy device or to
disable the connector.

If you set a serial connector to Auto and add an expansion card
containing a connector configured to the same designation, the
computer automatically remaps the integrated port to the next
available connector designation that shares the same IRQ setting
as follows:

COM1 (input/output [I/O] address 3F8h), which shares IRQ4
with COM3, is remapped to COM3 (I/O address 3E8h).

COM2 (I/O address 2F8h), which shares IRQ3 with COM4, is
remapped to COM4 (I/O address 2E8h).

NOTE: When two COM connectors share an IRQ setting, you can use

either connector as necessary, but you may not be able to use them both at
the same time. If you are running the Microsoft

®

operating system, you cannot use both serial connectors at the

OS/2
same time. If the second connector (COM3 or COM4) is also in use, the
integrated connector is turned off.

®

DMA Channel: This option determines the direct memory access
(DMA) channel used by the parallel connector and appears only
when Mode is set to ECP. The available options are DMA 1,
DMA 3, and Off.

– IDE Drive Interface: enables or disables the computer's

integrated device electronics (IDE) hard drive interface. With
Auto (the default) selected, the computer turns off the IDE
interface when necessary to accommodate a controller card
installed in an expansion slot. As part of the boot routine, the
computer first checks for a primary hard drive controller card
installed in an expansion slot. If no card is found, the computer
enables the IDE interface to use IRQ14 and IRQ15. If a primary
controller is detected on the expansion bus, the IDE interface is
disabled. Selecting Off disables the IDE interface.

– Diskette Interface: controls the operation of the computer's

integrated floppy drive controller. With Auto (the default)
selected, the computer turns off the integrated floppy drive
controller when necessary to accommodate a controller card
installed in an expansion slot.

With Read Only selected, nothing can be written to any floppy
drive using the computer's integrated floppy drive controller. (The
computer can still read from the drives.) When Read Only is
selected, Auto is also in effect, meaning that the computer turns
off the integrated floppy drive controller as necessary.

Selecting Off turns off the integrated floppy drive controller; this
setting is used to control the use of this legacy device or for
troubleshooting purposes.

– USB Emulation: determines whether the computer's basic

input/output system (BIOS) controls Universal Serial Bus (USB)
keyboards and mice. When On is selected (the default), the BIOS
controls USB keyboards and mice until a USB driver is loaded by
the operating system. When Off is selected, the BIOS does not
control USB keyboards and mice, although they function during
the boot routine. Set USB Emulation to Off if you are using a
PS/2-compatible keyboard and mouse.

56 Advanced Features

NOTE: For Windows NT®, Off is the default setting.

– Primary Video Controller: determines which video controller to

use when the computer boots. When Auto is selected, the
computer searches first for a PCI expansion card and then for an
AGP expansion card. If the computer has only an AGP expansion
card installed, the computer uses the AGP card; if the computer
has only a PCI expansion card installed, the computer uses the
PCI card; and if the computer has both AGP and PCI expansion
cards installed, the computer will use both cards. When AGP (the
default) is selected, the computer uses the AGP expansion card.

– Video DAC Snoop: lets you correct video problems that may

occur when you use certain video expansion cards. The default is
Off. If you are using a video expansion card and problems such as
incorrect colors or blank windows occur, set Video DAC Snoop to
On.

• Keyboard NumLock determines whether your computer boots with

the Num Lock mode activated on 101- or 102-key keyboards (it does
not apply to 84-key keyboards). When Num Lock mode is activated,
the rightmost bank of keys on your keyboard provides the
mathematical and numeric functions shown at the top of each key.
When Num Lock mode is turned off, these keys provide cursor-control
functions shown by the label on the bottom of each key.

• Memory Information indicates the amount of installed memory

detected in your computer, the computer memory speed, the amount
of video memory, and the size of the display cache. After you add
memory, check this option to confirm that the new memory is installed
correctly and is recognized by the computer.

• PCI IRQ Assignment specifies which IRQ lines are assigned to the

Peripheral Component Interconnect (PCI) devices installed in the
computer. Press <Enter> to configure these devices. Then select the
device whose IRQ line you want to change, and press the plus (+) or
minus (–) key to scroll through the available IRQ lines. Normally you
do not need to change the IRQ lines assigned to PCI devices unless a
particular device, device driver, or operating system requires a specific
IRQ line already in use by a PCI device.

NOTE: For Windows NT,

if Primary Video
Controller is set to Auto
and the computer has
both AGP and PCI
expansion cards installed,
the computer will use the
PCI expansion card.

• Primary Drive n and Secondary Drive n

Primary Drive n identifies drives attached to the primary IDE
interface connector (labeled “IDE1”) on the system board; Secondary
Drive n identifies drives connected to the secondary IDE interface

Advanced Features 57

connector (labeled “IDE2”). Use the secondary IDE interface
connector for IDE CD, DVD, and tape drives.

NOTE: For all devices obtained from Dell that use the integrated IDE

controller, set the appropriate Drive option to Auto.

NOTE: You must have an IDE device connected to the primary IDE

interface if you have an IDE device connected to the secondary IDE
interface.

The following settings identify the type of IDE devices installed in the
computer:

– Auto (use this setting for all IDE devices from Dell)

–Off

To choose a setting for each option, press <Enter> to access the field's
pop-up settings menu. Then type characters from the keyboard or press the
left- or right-arrow key to cycle through the settings.

NOTE: Operating

systems that bypass the
computer BIOS may not
obtain optimum hard
drive performance.

If You Have a Problem

If the computer generates a drive error message the first time you boot your
computer after you install an IDE drive, your drive may not work with the
automatic drive-type detect feature. Press <Alt><d> in any hard drive
field to set the hard drive autoconfiguration feature.

During POST the computer scans the IDE channels for supported devices
and generates a summary message. For example, if it finds that a hard drive
is connected to the Primary channel and a CD drive is connected to the
Secondary channel, it generates the following message:

Performing automatic IDE configuration...
Primary Master: IDE Disk Drive
Secondary Master: CD-ROM Reader

If it detects a device during the scan, it sets the device to Auto in system
setup. If no device is listed, it sets the device setting to Off in system setup.

If your computer does not reset after you perform these steps, enter system
setup and reset the computer to its original Dell settings.

1 Restart your computer.

Software Installation and
Configuration

When you obtain software, check it for viruses with virus-scanning software
before installing it on your computer's hard drive. Viruses can quickly use all
available computer memory, damage or destroy data stored on the hard
drive, and permanently affect the performance of the programs they infect.
Several commercial virus-scanning programs are available for purchase, and
most bulletin board services (BBSs) on the Internet archive freely
distributed virus-scanning programs that you can download with a modem.

60 Advanced Features

Before you install a program, read its documentation to learn how the
program works, what hardware it requires, and what its defaults are. A
program usually includes installation instructions in its accompanying
documentation and a software installation routine on its program floppy
disks or CD(s).

The software installation routine assists you in transferring the appropriate
program files to your computer's hard drive. Installation instructions may
provide details about how to configure your operating system to successfully
run the program. Always read the installation instructions before running a
program's installation routine. You may be instructed to modify some
operating system start-up files, such as config.sys and autoexec.bat, or the
installation routine may modify start-up files automatically.

When you run the installation routine, be prepared to respond to prompts
for information about how your computer's operating system is configured,
what type of computer you have, and what devices are connected to your
computer.

TAPI

The telephony applications programming interface (TAPI) system-board
connector uses a 4-pin cable to interface your internal TAPI-compliant
expansion card with the audio system in your computer. To locate the TAPI
system-board connector, see “System Board Components.” Your computer
supports TAPI-compliant cards using the standard TAPI connector (labeled
TELE). For example, you can connect your modem to the TAPI connector
and then use your audio speakers and microphone as a speakerphone. The
microphone carries your voice into the computer and then through the
TAPI system board connector to your modem card. The caller’s voice enters
through the modem card to the TAPI system board connector and then out
to the speakers. You can also use this configuration to record and play sound
files over the phone.

NOTE: See the

documentation that came
with the TAPI-compliant
expansion card for more
information on using
TAPI devices and to
verify the card works with
your computer.

Memory

You can increase memory up to 1 gigabyte (GB) by using synchronous
dynamic random-access memory (SDRAM) dual in-line memory modules
(DIMMs). The system board illustration shows the location of the DIMM
sockets on the system board. (DIMMs may either be error checking and
correction [ECC] or non-error checking and correction [non-ECC].
However, all DIMMs must be the same type of memory—either ECC or
non-ECC.)

When you add memory, you may install DIMMs in either socket. For
optimum operation, Dell recommends that you install a DIMM in socket A
first (closest to the processor) before installing a DIMM in socket B.
