Safety First—For You and Your Computer

The procedures in this section require that you open the cover and work inside your computer.

NOTICE: Do not attempt to service the co mputer yourself, except as

explained in this guide and elsewhere in Dell documentation. Always follow installation and service instructions closely.

NOTICE: Before disconnectin g a device from the computer or removing a

component from the system board, verify that the standby power light on the system board has turned off. For the location of this light, see the syste m

board.

Working inside your computer is saf e—if you observe the following precautions.

CAUTION: FOR YOUR PERSONAL SAFETY AND PROTECTION OF

THE EQUIPMENT.

Before you start to work on the computer , perform the following steps in the sequence indicated:

1 Turn off the computer and all devices. 2 Touch an unpainted metal surface on the computer chassis , such as the

metal around the card-slot openings at the back of your computer, before touching anything inside your computer.

3 Disconnect the computer and devices from their electrical outlets.

Doing so reduces the potential for personal injury or shock. Also disconnect any telephone or telecommunication lines from the computer.

In addition, take note of these safety gu idelines 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, pre ss 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.

• 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 b y its edges, not by its pins.

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

incorrectly installed. Replace the batter y only with the same or equivalent type recomme nded by the manufacture r. Discard used batteries according to the manufacturer's instructions.

Electrostatic Discharge

Static electricity can harm delicate components inside your computer. To

www.dell.com | support.dell.com

prevent static damage, discharge static electricity from your body before you touch any of your computer’s electroni c 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 f r om electrostatic discharge (ESD):

• When unpacking a static-sensitive component from its shipping

carton, do not remove the compon ent from the antistati c packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electric ity from your bo dy.

• 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.

Ergonomic Computing Habits

CAUTION: Improper or prolonged keyboard u se may resul t in

injury.

CAUTION: Viewing the monitor screen for extended periods of

time may result in eye strain.

For comfort and efficiency, observe the following ergonomic guidelines when setting up and using your computer:

• Position your computer 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 position your keyboard.

• Set the monitor at a comforta ble viewing distance (u sually 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.

• 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 your work activities. Try to organize your 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.

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 di sabled 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 will

only wake 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 yell ow 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. W h en the light is off, the computer is not detecting a physical connection to the network.

30 About Your Computer

Network Cable Requirements

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 P ort 1 and Serial P o rt 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 contr ol 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 rema ps 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

OS/2

operating system, you cannot use both serial co nnectors at the same time. If the second connector (COM3 or COM4) is also in use, the integrated connector is turned off.

Windows® 95 or IBM®

– Parallel Port configures the computer's integrated parallel

connector. Press <Enter> to configure the Parallel Port options explained in the following subsections.

Mode: You can set this option to PS/2, EPP, ECP, AT , or Off to control the use of this legacy device or to disable the connector. Set this option acco rding to the type of device connec ted to the parallel connector. To determine the correct mode to use, see the documentation that came with the device.

I/O Address: This option determines the I/O address used by the parallel connector and appears except when Mode is set to Off. You can set I/O Address to 378h (the default), 278h, or 3BCh.

NOTE: You cannot set the parallel connector to 3BCh if Mode is set to

EPP.

Advanced Features 55

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

www.dell.com | support.dell.com

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: det ermines which video controller to

use when the computer boots. When Auto is selected, the computer searches first for an AGP expansion card and then for a PCI 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 labe l 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 AGP 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 interfa ce

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)

www.dell.com | support.dell.com

–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 ti me you boot yo ur computer after you install an IDE drive, it may mean that your particular drive does not work with the automatic drive-type detect feature. If you suspect that your problem is related to drive type, press <Alt><d> in any of the hard drive fields to set the hard drive autoconfiguration feature. During POST the IDE channels will be scanned for supported devices and a message will appear detailing what was found. For example, if you had a hard drive connected to the Primary channel and a CD drive connected to the Secondary channel, this message would be displayed:

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

If a device is detected during the scan, it will be set to Auto in system setup. If a device position does not have a device, it will be set to Off in system setup.

Removing the Microprocessor

NOTICE: Be careful not to bend any of the pins when yo u remove the

microprocessor from its socket. Bending the pins can permanently damage the microprocessor.

Your microprocessor socket is a zero insertion force (ZIF) socket with a lever-type handle that secures the microprocessor in, or releases it from, the socket.

1 Pull the release lever straight up until the microprocessor is released,

and then remove the microprocessor from the socket.

2 Leave the release lever extended so that the socket is ready for the new

microprocessor.

NOTE: Do not discard

the blower; reuse the blower. Your microprocessor upgrade kit from Dell includes on ly a replacement heat sink and two replacement securing clips.

NOTICE: You must position the microprocessor correctly in the socket to

avoid permanent damage to the micropro cessor and the computer when you turn on the computer.

If the release lever on the socket is not fully extended, move it to that position now.

4 With the pin-1 corners of the microprocessor and socket aligned, align

the pins on the microprocessor with the holes in the socket.

NOTICE: When you place the microprocessor in the socket, be sure that all of

the pins go into the corresponding holes on all sides of the socket. Be careful not to bend the pins.

Installing Upgrades 93

5 Set the microprocesso r lightly in the socket and make sure all pins are

headed into the correct holes. Because your computer uses a ZIF socket, there is no need to use force (which could bend the pins if the microprocessor is misaligned). When the microprocessor is positioned correctly, press it with minimal pressure to seat it.

6 When the microprocessor is fully seated in the socket, pivot the release

lever back toward the socket until it snaps into place, securing the microprocessor.

IDE Drive Addressing

All IDE devices require that you configure the cable select setting, which assigns master and slave status to devices according to their position on the interface cable. You usually configure a drive for cable select by setting a jumper or switch, depending on the drive. Refer to t he drive documentation in your upgrade kit for information on configuring devices for the cable select setting. When you connect two IDE devices to a single IDE int erface cable and configure them for the cable select setting, the device attached to the last connector on the interface cable is the master or boot device (drive

0), and the device attached to the middle connector on the interface cable is the slave device (drive 1).
