Introduction 1

Using the built-in interfaces, you can connect most of your peripheral devices directly to the computer, so you do not have to install option cards. You can use the option slots to enhance your system with extra functions such as a modem card, a network controller card, or additional interface ports.

The shadow RAM feature speeds up processing by moving the system and video BIOS into the RAM area of memory.

With the standard 512KB of video RAM, the VGA controller supports standard resolutions up to 640 x 480 in 16 colors and extended resolutions up to 640 x 480 in 256 colors or 1024 x 768 in 16 colors (interlaced or non-interlaced). When you upgrade to 1MB of video RAM, the system supports extended resolutions up to 1024 x 768 in 256 colors.

Your system may have been configured for you. If so, everything you need to get started is already in place. Your hardware configuration options have been set to ensure optimal system performance. The hard disk drive already contains the MS-DOS®operating system and Microsoft@ Windows.TMIn addition, the drivers needed to take advantage of your system’s enhanced video resolutions have been installed for you. Just connect your keyboard, mouse, and monitor and you’re ready to go.

VGA Drivers

Your computer comes with VGA drivers for use with the integrated VGA interface. With these drivers, you can take advantage of the extended VGA features such as high resolutions and 132-column text mode when you run popular application programs. If your system was configured for you, these drivers are already installed. If you need to install them yourself, a README file on your Utility diskette describes how to install the VGA drivers for common application programs.

2 Introduction

OptionaI Equipment

You can easily upgrade your computer by installing additional memory and a wide variety of options, as described below. (Installation instructions are provided in Chapters 4 and 5.)

System Memory

By adding 4MB, SMB, 16MB, and 32MB SIMMs (single inline memory modules) to the main system board, you can expand the computer’s memory up to 64MB.

Cache Memory

You can increase your cache memory to 64KB, 128KB, or 256KB by installing SRAM chips on the main system board. Additional cache allows your system to access frequently used

data faster, improving overall system performance.

Video Memory

You can install video memory chips to increase the video memory to lMB, allowing you to use higher resolutions with

more colors.

Microprocessor

You can upgrade your system with these microprocessors:

486SXJ 33 486DW 33 486DX2150

486DX2166.

Introduction 3

Chapter 1

Setting Up Your System

This chapter briefly describes how to set up your computer. It includes the following information:

Getting started

Connecting peripheral devices

Turning the computer on and off.

Getting Started

Follow the instructions below for choosing a location for your

new system and unpacking it.

Choosing a Location

When you are ready to set up your system, choose a safe,

convenient location that provides the following:

A flat, hard surface. Surfaces like beds and carpets attract

static electricity, which can erase data on your disks, damage the computer’s circuitry, and prevent proper ventilation.

Moderate environmental conditions. Select a cool, dry area

and protect your computer from extremes in temperature, humidity, dust, and smoke. Avoid direct sunlight or other

sources of heat.

Good air circulation. Leave several inches of space around the computer so air can move freely.

Setting Up Your System

l-l

No electromagnetic interference. Do not place your system too close to any electrical device, such as a telephone or television, which generates an electromagnetic field.

Appropriate power source. Connect all your equipment with the appropriate power cords for the power source in your area.

Unpacking Your Computer

When you unpack your system components, make sure you have these items:

computer

diskette

keyboard

manual

Your system may also include an EPSON PS/2 compatible mouse and may come with the operating system and software already installed on a hard disk drive.

If you purchased any optional equipment that wasn’t installed at the factory—such as option cards, memory modules, a hard disk, or a diskette drive-you install these options before you connect your computer. See Chapters 4 and 5 for instructions.

Place your monitor on top of or near the computer. Turn the monitor and computer around so the backs are facing you.

There should be two cables provided with your monitor: the monitor cable (to connect it to the computer) and the power cable (to connect it to the power source). On most monitors,

the monitor cable is permanently attached to the monitor. If your monitor does not have an attached cable, connect the cable to it now.

1-4

Examine the connector on the monitor cable and line it up with the Sport on the computer. Then insert the connector into the port.

Caution

To avoid damaging the connector, be careful not to bend the pins when you insert it.

Setting Up Your System

If the connector has retaining screws, tighten them.

Plug the monitor’s power cord into the power inlet on the back of the monitor.

Plug the other end of the power cord into a grounded electrical outlet or into the power outlet on the back of the computer.

Caution

Before you plug the monitor’s power cord into the back of your computer, make sure the monitor’s power requirements do not exceed 1 Amp.

Connecting a Printer or Other Device

Your computer has one bidirectional parallel and two serial ports. To connect a printer or other peripheral device, follow the appropriate instructions below.

Using the parallel port

Follow these steps to connect a parallel printer:

Place the printer next to the computer so that the backs are facing you.

Align the connector end of the printer cable with the

PARALLELport and plug it in. If the connector has retaining screws, tighten them.

Connect the other end of the cable to the printer. To secure

the cable, squeeze the clips at each side of the printer port

and push them into place.

Plug the printer’s power cord into a grounded electrical outlet.

WARNING

To avoid an electric shock, be sure to plug the cord into the computer before plugging it into the wall outlet.

1-6

Plug the other end of the power cord into a grounded electrical outlet.

Setting Up Your System

Turning On the Computer

After you set up your system, you are ready to turn on the power. Use the illustration below to identify the features of your system’s front panel. (Your computer’s front panel may look a bit different from the one illustrated in this manual.)

Before you turn on your computer, check the following safety rules to avoid accidentally damaging your computer or injuring yourself

Do not connect or disconnect any peripheral device cables

(including the keyboard or a mouse) or power cables unless

the computer’s power is off.

Never turn off or reset your computer while a disk drive light is on. This can destroy data stored on the disk.

Never turn on the computer with a protective card in the

diskette drive.

Setting Up Your System

1-7

Always wait at least 20 seconds after you turn off the power before you turn it on again to prevent possible damage to the computer’s electrical circuitry.

Do not leave a beverage near your system. Spilled liquid can damage the circuitry of your equipment.

Follow these steps to turn on your system :

Turn your computer around so the front panel faces you. Place your monitor, printer, and other devices in a convenient arrangement.

If there is a protective card in the diskette drive, remove it.

Turn on the monitor, printer, and any other devices connected

to the computer.

Turn on the computer by pressing the power button on the right side of the front panel.

The power indicator lights up, then the screen displays the BIOS version number and copyright information. The computer performs its power-on diagnostics, which are a series of checks that make sure everything is working correctly. During diagnostics, you see a screen message telling you to press F2 to run the SETUP program. (Chapter 2 describes starting and using SETUP.)

1-8

When the computer completes its testing, it displays a screen describing the system’s configuration. If necessary, press the Pause key on the keyboard to view the configuration screen. Then press any key to continue the startup process.

If necessary, use the controls on your monitor to adjust the brightness and contrast until you can easily see the characters on the screen. If your monitor has horizontal and vertical hold controls, you may need to use them to

stabilize the display.

Setting Up Your System

If your system is configured to automatically load a program (such as Microsoft Windows or a word processing program), you see the first menu or screen display of that program. If not, you may see the operating system prompt, such as C: \> or A: \>.

If there is no operating system installed on your computer, you see an error message. Ignore the message for now; once you install the operating system, you will not see it.

Now you need to run the SETUP program to make sure your computer is configured properly. First turn off the computer, as described below, then see Chapter 2 for instructions. When you finish running SETUP, be sure to see “Post-SETUP Procedures” on page 2-13 for guidelines on what you need to do next.

Turning Off the Computer

Whenever you turn off your system, follow these steps:

Save your data and exit any application program you are

using.

Check the hard disk drive light and the diskette drive light(s) to make sure they are not on. Do not turn off the computer if a drive light is on, because you can damage the drive or lose data.

Remove any diskette(s) from the diskette drive(s).

Press the power button to turn off the computer.

Turn off the monitor, printer, and any other peripheral devices.

Setting Up Your System

1-9

Chapter 2

Running the SETUP Program

You may need to run the SETUP program the first time you use your computer. If your system came unconfigured, you need to define how it is set up. If your system was configured for you, you may want to check the settings or adjust the date and time. You also may need to run the program again later if you change your configuration.

SETUP lets you verify or change the following:

System settings such as date, time, diskette drive type(s): and video display type

Automatic or manual selection of hard disk drive(s)

Automatic or manual selection of advanced hardware features for optimizing system performance

System booting options

Password security and anti-virus features.

SETUP also allows you to see summary information about your system.

The SETUP program and the factory default settings are stored in the computer’s ROM BIOS (read-only memory, basic input/ output system). The configuration information you enter is stored in an area of memory called CMOS RAM. This memory is backed up by a battery, so it is not erased when you turn off or reset the computer.

Running the SETUP Program

2-1

Starting the SETUP Program

When you start your computer, it performs some power-on diagnostics. During these diagnostics, you may see the following message:

Press <F2> to enter SETUP

(In SETUP, you can disable this message, if desired.)

Press F2 to run SETUP. This message is only on the screen for a few seconds. If you missed it, restart the computer and try again.

If the system detects an error in your configuration, you hear two beeps and see an error message followed by this message:

Press <Fl> to resume, <F2> to Setup

Press F2 to run SETUP.

SETUP displays the Main Menu. From this menu, you can

select the various options to identify your system’s configuration and then save your new values to CMOS. If you change your mind, you can cancel any changes you have made

and restore the default values stored in ROM or load the values previously stored in CMOS.

The System Setup Option

When you select this option, you see the System Setup screen. From this screen, you can set the system time and date, define your video display type, check system memory, and define the diskette drives.

Setting the Time and Date

The real-time clock in your computer continuously tracks the date and time-even when the computer is turned off. Once you set the System Time and System Date options, you

should not need to change them, unless you adjust the time for

daylight savings or a different time zone. (The computer

automatically changes the date for leap years.)

Running the SETUP Program

Setting the Video Display Type

The Video System option allows you to define the type of display you are using. If you have a VGA monitor that you connected to the computer’s built-in VGA port, select EGA/VGA.

If you connected a monitor that doesn’t support VGA to a video adapter card installed in your system, select either the

CGA 80 X 25 or the Monochrome option. If you installed a video adapter card, make sure you disabled the onboard VGA controller by setting jumper 518 to the Off position. (See

Chapter 4 for instructions.)

Checking System Memory

Your computer comes with 4MB of RAM on a SIMM. MS-DOS

and application programs that run under MS-DOS use the first

640KB of memory. The memory above 1MB is extended memory.

When you boot your system, the system BIOS detects the total memory size automatically. You see the memory configuration

displayed in the System Memory and Extended Memory fields on this SETUP screen.

You cannot change these values; if they are not what you

expect them to be, check that the SIMM(s) are securely seated

in their sockets. (See Chapter 4 to locate the SIMM sockets.)

Setting the Diskette Drive(s)

On your system, diskette drive A is the 3.5-inch high-density

drive installed in the lower drive bay. You may also have

another drive of a different size or capacity; this is drive B.

Check the settings for both drives and correct them if necessary.

2-4

Running the SETUP Program

The Fixed Disk Setup Option

The Fixed Disk Setup options define the types of hard disk drives you installed in your system. When you select this option, you see the Fixed Disk Setup screen. From this screen, select Fixed Disk 0 Controlor Fixed Disk 1

Control.

Your computer comes with a hard disk auto-sensing feature. Press Enter when the Autotype Fixed Disk option is highlighted. The system detects the type of hard disk drive and fills in the remaining fields on the screen.

If you are using an older drive or a preformatted drive, it may not support the auto-sensing feature. If you press Enter when the Autotype Fixed Diskoption ishighlighted and the drive parameters do not match your drive, check Appendix A to see if your drive’s parameters are included in the hard disk drive table. If not, you need to define your own drive type or reformat the disk. See the next section for instructions on how to define your own drive type.

Defining Your Own Drive Type

If the parameters for your hard disk do not match the parameters detected by the auto-sensing feature, or if you want to use your drive with parameters other than the defaults, you can define your own type. (See Appendix A for a list of predefined hard disk drive types and their parameters.)

To define your own drive type, follow these steps:

Move the cursor to Type and select User.

Type the values in each field that are appropriate for your hard disk drive.

When you exit SETUP, make sure you save your changes.

Running the SETUP Program

The Advanced System Setup Option

When you select this option from the Main Menu, you see the Advanced System Setup screen. From this screen, you can select options that allow you to configure the computer’s cache memory and shadow memory, and define the advanced chipset options.

Note

Your system can automatically configure the Advanced System Setup options for you. To avoid configuration problems, you should let the system configure these options.

Configuring Cache Memory

The system can configure your Memory Cache options or you can manually set them. If you installed external cache, enabling cache memory improves system performance, especially in large data retrieval and processing environments.

If you choose to configure the cache memory yourself (rather than let the system configure it for you), you can define the write and burst wait states and two non-cacheable areas of memory. However, it’s a good idea to let the system automatically configure these features.

Configuring Memory Shadow

The system can configure the Memory Shadow options or you can manually set them. You can enable or disable shadowing of your system and video memory and control the specific blocks of ROM used for this purpose.

2-6

Running the SETUP Program

Your computer can access RAM faster than ROM. The options on this screen allow your system to copy the contents of its system and/ or video ROM into RAM. When you use shadowing, your system can perform certain operations faster, providing a significant increase in performance.

Note

For the best system performance, always set the System shadow and the Video shadow options to Enabled.

If you enable shadowing for specific blocks, the ROM located in these blocks is copied to the shadow area.

Configuring Chipset Registers

The system can set your Advanced Chipset Control options or you can manually change the values in the chipset registers. Setting these values correctly increases your system performance; however, setting them incorrectly may cause your system to malfunction or shut down. Be sure to set the Auto Configuration option to Enabled to let the system automatically configure these options to avoid problems.

Running the SETUP Program

2-7

Setting the Boot Options

When you select Boot Options from the Main Menu, you see the Boot Options screen. These options allow you to define the boot sequence and determine the information you see on the screen when you start up your system.

The Disk drive boot sequence option determines the order in which the computer checks the drives when it looks for the operating system.

If you select A: then C:, each time you turn on the

computer, it first tries to load the operating system from drive

A. If drive A doesn’t contain an operating system, the computer loads it from drive C. If you select C : then A:, the computer tries to load the operating system from drive C first. If drive C doesn’t contain an operating system, the computer tries to load it from drive A. If you select C : only, the computer tries to load the operating system from drive C only.

If you set the Disk drive boot sequence option to C: only, you can disable the Floppy seek option so the system does not try to access the diskette drive at startup. Disabling the Floppy seek option decreases the time needed

to boot the system.

The Display SETUP prompt during POST option allows you to disable the message Press <F2> to enter SETUP that you see during power-on diagnostics. You may want to disable this prompt to prevent unauthorized users from seeing the SETUP prompt. Even when the message is disabled, however, you can still start SETUP by pressing F2 within the allowed amount of time.

2-8

Running the SETUP Program

The Pause on POST errors option allows you to disable the error message and the message Press <Al> to resume, <F2> to Setup that you see when the system identifies a configuration error. If you disable this option, the system ignores configuration errors it finds during power-on diagnostics and starts as it normally would. It’s a good idea to keep this option enabled.

By disabling the System summary screen at boot option, you can disable the system summary screen that you see when you start the system. If you disable this option, your system starts up faster. You can see the same screen by selecting the System Summary option from the Main Menu. (See page 2-12.)

The System Security and Anti-Virus Options

When you select the Security and Anti -Virus option from the Main Menu, you see the System Security and Anti-Virus screen. The password options on this screen let you define both a Supervisor and a User password. You can specify whether a password is required when you start the system.

The Diskette Access option allows you to restrict diskette access at either the User or Supervisor password level to protect your system from receiving a virus from a diskette.

Entering or changing a Password

You can define both User and Supervisor password levels for this system. If the system will be used by more than one person, you may want to set a Supervisor password for yourself and a User password for others you don’t want to have complete access to the system. For instance, you may want to restrict access to the diskette drives or the computer’s virus protection features.

Running the SETUP Program

2-9

If you enable the Password on boot option, you must enter the Supervisor or User password each time you turn on the system. If you do not enable this option but you have defined passwords, you must enter the password each time you start the SETUP program. If both a Supervisor and User password are enabled, SETUP displays options for setting the User password only for users who logged on with a user password.

To specify a User password, you must first specify a Supervisor password, follow these steps to enter or change a Supervisor password:

Select the Set Supervisor Password option and press

Enter.

You see a Set Supervisor Password window. Type the password you want to use, then press Enter. You can define

a password of up to eight characters.

Type the same password a second time and press Enter. You

see a message that your changes have been saved.

Press the spacebar. The Supervisor Password IS option is now set to Enabled.

To set a User password, select the Set User Password option and follow the steps above.

Deleting Passwords

To delete your passwords, follow these steps:

Set the Password on boot option to Disabled.

Delete the User password by pressing Enter for both the password field and the confirmation field. Don’t type any characters in these fields.

2-10

Running the SETUP Program

Then delete the Supervisor password the same way.

Note

You must delete the User password before SETUP will

allow you to access the Supervisor password.

If you have forgotten your password(s), see “Password Problems” in Chapter 6.

Using the Diskette Access Option

The Diskette Access option allows you to restrict access to your diskette drives based on the password levels you have defined. This prevents unauthorized users from accessing the drives and possibly introducing a virus into your system. You can restrict access only if passwords are enabled and you have enabled the Password on boot option.

If you select Supervisor for this option you can access the diskette drives only if you enter the Supervisor password during system startup. Someone who starts the system with a User password, however, will see an error message when he or

she tries to access the diskette drive. If you select User for the Diskette Access option, you can access the diskette drives

whether you enter the Supervisor or User password during

startup.

Note

To use passwords for diskette drive access, you must enable the Password on boot option. If you select a password level for Diskette Access, but leave the Password on boot option disabled, you see an error message whenever you try to access your diskette drive.

Running the SETUP Program

2-11

The System Summary Option

When you select the System Summary option from the Main Menu, the SETUP program displays a summary of the configuration settings for your system.

This is the same screen you see during system startup. You can choose not to have the system display this screen so system startup is faster. See page 2-8 for information on disabling this option.

Exiting SETUP

When you leave SETUP, you can save your settings, or exit SETUP without saving your settings. You can also return all values to the factory defaults.

To leave SETUP, press ESC from any SETUP screen. From the Main Menu, you can do the following:

Using Your Computer

This chapter briefly describes the following operations:

Working comfortably

Inserting and removing diskettes

Stopping a command or program

Resetting the computer

Using the password

Changing the processor speed.

Working Comfortably

Use the guidelines to create a comfortable work environment:

Use good posture. Keep your elbows, hips, and knees bent at approximately 90 degree angles and keep your wrists as close to horizontal as possible.

Vary your posture often and take frequent breaks. Stand up, stretch, and move around.

Use a good chair. Make sure your chair supports your lower back. Padded armrests let you rest your arms as you work.

If you use a copy stand, keep it at the same eye level as your screen. This reduces eye and neck strain. Also, rest your eyes occasionally by closing them or focusing on a fixed spot in the distance.

Using Your Computer

3-1

Place your monitor directly in front of you and sit about an arm’s length away from it. The top of the screen should be slightly below your eye level so you look down at the screen. Position the monitor so that no light is reflected

from the screen.

Use good lighting that isn’t too bright. Try to keep bright light sources out of your field of vision when you are looking at the screen.

Be gentle with your keyboard. Too much force creates tension in your hands. Also, make sure your work surface has enough room for you to move the mouse or other pointing device freely.

Inserting and Removing Disks

To insert a diskette into a 3.5-inch drive, hold the diskette with

the label facing up and the metal shutter leading into the drive,

as shown in the following illustration. Slide the diskette into

the drive until it clicks into place.

Using Your Computer

To insert a diskette into a 5.25-inch drive, hold the diskette with the label facing up and the read/ write slot leading into the drive. When the diskette is completely in the drive, turn down the latch to secure the diskette in the drive.

When you want to remove the diskette, make sure the drive light is off; then press the release button or turn the latch. Remove the diskette and store it properly.

Caution

Never remove a diskette, reset the computer, or turn it off

while a diskette drive light is on. You could lose data. Also, remove all diskettes before you turn off the computer.

Sopping a Command or Program

You may sometimes need to stop a command or program while it is running. If you have entered a DOS or application program command that you want to stop, try one of the following:

Press Pause

Press Ctrl C

Press Ctrl Break.

If these methods do not work, you may need to reset the computer as described below. Do not turn off the computer to exit a program or stop a command unless you have to, because the computer erases any data you did not save.

Using Your Computer

3-3

Resetting the Computer

Occasionally, you may want to clear the computer’s memory without turning it off. You can do this by resetting the computer.

For example, if an error occurs and the computer does not respond to your keyboard entries, you can reset it to reload your operating system and try again. However, resetting erases any data in memory that you have not saved; so reset only if necessary.

Caution

Do not reset the computer to exit a program. Some programs classify and store new data when you exit them. If you reset the computer without properly exiting a program, you may lose data.

When you reset the computer, the operating system must be either on the hard disk or on a diskette in drive A; so if you do not have a hard disk, insert the operating system diskette in drive A. If you are using DOS, you can hold down Ctrl and Alt and press Del.

If you set the Disk drive boot sequence option in SETUP to C: only (see Chapter 2), the operating system must be on the hard disk when you reset the computer. If you selected A: then C: or C: then A:, the operating system must be either on the hard disk or on a diskette in drive A. If you do not have a hard disk, insert a bootable diskette (one that contains the necessary portions of the operating system) in drive A. If you are using MS-DOS, press Ctrl Alt and Del to reset the system.

You can also press the RESETbutton located on the front panel of your computer. The screen displays nothing for a moment and then the computer reloads the operating system.

3-4

Using Your Computer

If resetting the computer does not solve the problem, you need to turn it off and on again. Remove any diskette(s) from the diskette drive(s), turn off the computer, and wait 20 seconds. If you do not have a hard disk drive, insert a bootable diskette in drive A. Then turn on the computer.

Using a Password

In SETUP, you can define both a Supervisor level password and a User level password. You can also specify whether a password is required when you boot the system. This password can also control access to the diskette drives.

If `you enabled the Password on boot option in SETUP, you must enter the Supervisor or User password every time you turn on or reset the computer. If you entered a password but disabled the Password on boot option, you must enter the password when you start SETUP.

If you set the Diskette Access option to Supervisor, you can access a diskette drive only if you entered a Supervisor password when you started the system. If you entered a User password but the Diskette Access option is set to Supervisor, you see an error message when you cannot access the diskette drive.

When you enter your password, you’ll see the prompt, Enter password:. As you type your password, you see a rectangle for each character you type. When you press Enter, the computer loads the operating system (or starts SETUP).

If you don’t enter the correct password the first time you type it, you can try two more times. If you haven’t entered the correct password on the third try, the computer locks up to prevent unauthorized access. You see the message:

System Disabled!

Using Your Computer

3-5

You must turn off the computer and start over. You can reset the computer using the RESETbutton but you cannot reset the computer by pressing Ctrl Alt and Del.

Note

If you want to change or delete your password, you must run the SETUP program as described in Chapter 2.

If you do not remember your password, see “Password Problems” in Chapter 6.

Changing the Processor Speed

Your computer’s processor can operate at two speeds: fast (the

speed of your microprocessor) or slow (8 MHz). The slow speed is available to provide compatibility with older application programs.

When your computer is operating at fast speed, the speed light

(labeled

operating at slow speed, the light is off.

TURBO)

on the front panel is on. When the computer is

You should use fast speed for almost everything you do because your programs will work faster. However, certain

application programs have specific timing requirements and can run only at the slower speed. See your software manual to determine if this is the case.

Some copy-protected programs require the computer to run at

slow speed while accessing the program on a diskette. These programs also usually require you to leave a key disk-the diskette that contains the copy protection-in the diskette drive. If you use a copy-protected program, you can change the

speed to slow to access the diskette and return it to fast speed when you are finished.

3-6

Using Your Computer

You can change the processor speed temporarily by entering one of the following commands from the numeric keypad on your keyboard :

To select slow speed, press Ctrl Alt and then press the -key on the numeric keypad. This turns off the speed light.

To select fast speed, press Ctrl Alt and press + on the numeric keypad. The speed light comes on.

Note

You can use the commands listed above while you are running a program. However, if the program uses one of these commands for another function, you cannot use it to change the processor speed.

The speed setting remains in effect until you one of do the following:

Reset your computer

Turn off your computer

Change the speed with another keyboard command

Change the jumper setting of J25 (as described in Chapter 4).

lnstalling an Option Card

This section explains how to install option cards in your computer. Your computer has three 16-bit, full-length slots and two S-bit, half-length slots to accommodate a total of five option cards.

As you install option cards, keep these guidelines in mind:

Usually it does not matter which slot an option card occupies as long as the card fits in the slot. For example,

you can place some S-bit cards in a 16-bit slot. When you

select the slot you want to use, make sure that no components are touching or obstructing other cards or cables.

If you have a DX or DX2 processor installed, you may not be able to install a 16-bit card in the bottom slot because a heat sink or heat sink/ fan assembly may be mounted on the processor.

When you unpack the option card, be careful not to touch

any of the components on the circuit board or the gold-edged connectors. If you need to set it down before you install it, place it gently on top of its original packing materials with the component side facing up. Keep the packing materials in case you remove the card later.

4-14

Before you install the card, adjust any switches or jumpers on it, if necessary. (See your option card documentation for instructions.) Also, see if you need to change any jumper

settings on the system board. For example, if you install a

SCSI hard disk drive, you may need to change jumper 523 to disable the IDE hard disk drive controller. See page 4-6 for more information on jumpers.

Installing and Removing Options

Caution

Make sure the power requirements for the option cards you install do not exceed the power supply limitations. See your option card manual(s) for the power requirements. Then check Appendix A for the option slot power limits.

Refer to the illustrations below and follow these steps to install

an option card:

If you are using a 16-bit option slot, go on to step 2. If you are using an S-bit slot near the power supply, you need to

move the power supply before you can remove the metal

slot cover.

Installing the Video Chips

Follow these steps to install additional video DIP chips:

Locate the memory chip sockets on the main system board, shown on page 4-5.

Bank 0 contains two chips soldered onto the main system board, so you cannot add video memory in this bank. Bank

1 contains the two filled sockets closest to the soldered chips. Bank 2 is the two middle sockets and Bank 3 consists of the remaining two sockets.

If there is an option card in your way, remove it. See page 4-18 for instructions.

Removing Options 4-21

Caution

To avoid generating static electricity and damaging the memory chips, ground yourself by touching the metal surface on the inside of the computer’s back panel. Then remain as stationary as possible while you install them.

Remove the memory chips from their package and inspect each one. The pins should point inward at slightly less than

a 90o angle.

If any of the pins are bent, straighten them gently with your fingers or with small tweezers to align them with the other pins. Be careful when you do this; the pins are fragile and can break off easily.

Position one of the video chips over the first empty socket as

shown below, aligning the pins on the chip with the holes

in the socket. Make sure the notch in the end of the chip is

aligned with a similar notch in the socket.

4-22

Installing and Removing Options

Gently press the chip halfway into the socket (to make sure it is correctly aligned). If the chip goes in at an angle, remove it with a chip puller or a small flat-head screwdriver and try again.

When the chip is properly positioned, push down firmly on both ends of the chip to make sure it is well-seated.

Repeat steps 4 through 6 for each of the remaining chips.

Replace any option cards you removed. See page 4-14 for instructions.

When you start your computer, it displays the video memory briefly before it begins its memory test.

lnstalling ExternaI Cache

You can install 64Kl3,128KB, or 256KB of external cache on

your system.

To install 64KB of external cache, use eight SRAM, 28-pin,

8K x 8,20ns DIP chips, and one 8K x 8,20ns tag chip

To install 128KB of external cache, use four SRAM, 28-pin,

32K x 8,20ns DIP chips, and one 32K x 8,20ns tag chip

To install 256KB of external cache, use eight SRAM, 28-pin,

32K x 8,20ns DIP chips, and one 32K x 8,20ns tag chip.

For the cache memory to work properly, you must install chips in the following configuration (each bank contains four cache memory sockets).

Make sure you ground yourself before you touch the processor chip. Then remain as stationary as possible while you install it. Do not touch the pins on the

processor chip. Handle the microprocessor only by the

edges of its case.

Installing and Removing Options 4-27

If you use a chip puller, position the puller between the

processor chip and the socket.

You can also use a small, flat-edged screwdriver instead of a chip puller. Carefully wedge the tip of the screwdriver

between the processor chip and the socket. Gently turn the

screwdriver until the chip begins to separate from the

socket. Move the screwdriver to another side of the processor chip and again turn it until the chip separates from the socket. Keep doing this until you can lift the processor chip straight up from the socket.

Caution

The 486SW 25 microprocessor may be soldered onto an adapter board that is seated in the microprocessor socket. Make sure you position your chip puller or screwdriver just above the socket to avoid damaging the adapter board.

Gently pull the processor chip straight up and set it aside.

Remove the replacement chip from its package and inspect

the pins. If they are bent, do not install the processor chip.

Contact your vendor for a new microprocessor.
