2 Introduction

Energy Savings

In standard configurations, this computer complies with the United States Environmental Protection Agency’s Energy Star Program, which promotes the manufacture of energy-efficient printers, computers, and monitors. Your computer’s

“Green PC” feature places the hard disk drive in a low-power standby mode when the mouse and keyboard have been inactive for a specified period of time. It also stops sending video signals to your monitor.

Note

If you have an Energy Star compliant monitor, it also goes

into a low-power standby mode because it isn’t receiving video signals from your computer. (Screens on non-compliant monitors go blank, but do not enter a

low-power standby mode.)

VGA Drivers

Your computer comes with VGA drivers and utilities for use with the integrated video interface. With these drivers, you can take advantage of the extended VGA features such as higher resolutions and 132-column text mode when you run popular applications. If your system was configured for you, these drivers and utilities may be installed on your hard disk. If you need to install them yourself, see the instructions in Chapter 1. To obtain drivers for additional applications, call the EPSON ConnectionSM or access the Epson America Forum on CompuServe®.

Introduction 3

Optional Equipment

You can easily upgrade your computer by installing additional memory and a wide variety of options, as described in Chapters 3 and 4.

Memory By adding 1MB, 2MB, 4MB, 8MB, 16MB, or

32MB SIMMs (single inline memory modules) to the main system board, you can expand the computer’s memory up to

64MB.

Video

Memory

CPU

Cache

Drives

You can increase the video memory in your system to 1MB, which allows you to use higher resolutions with more colors.

Your system supports a variety of

microprocessors, including 5 Volt, 3.3 Volt,

3.45 Volt, and 3.6 Volt processors; see Chapter 3 for more information.

You can increase the external cache

memory size to 64KB, 128KB, or 256KB by

installing cache SRAM chips on the main system board, allowing you to access data

faster and improve overall system

performance.

Your system supports up to four mass storage devices, including hard disk drives, diskette drives, a tape drive, a CD-ROM drive, or an optical drive.

Setting Up Your System

1-1

If you purchased any optional equipment that goes inside the computer-such as option cards, memory modules, or drives-you should install these devices before you connect

your computer. See Chapters 3 and 4 for instructions.

Setting the Voltage Selector Switch

Your system is powered by a 200 Watt power supply. The power supply voltage is controlled by a voltage selector switch on the computer’s back panel. You can set this switch to

110 VAC or 220 VAC.

EPSON ships the computer with the voltage selector switch set to 110 VAC. This setting is appropriate for line source voltages between 100 and 120 VAC, and is generally the appropriate setting to select if you plan to use your computer in North America, South America, or Japan.

If you plan to operate the computer in the United Kingdom, Europe, or some South American countries, you will probably need to reset the voltage selector switch to 220 VAC. Doing so allows your computer to handle line source voltages between 200 and 240 VAC, which are standard in Europe.

1-2 Setting Up your System

Caution

Before you turn on the power to your system, make sure the voltage selector is set to the appropriate setting for the electrical power source in your location or you will seriously damage your system.

To change the voltage selector switch setting, slide the switch to the right to select 220 VAC or to the left to select 110 VAC.

Caution

Although the connectors and ports for the mouse and keyboard are physically identical, they cannot be used interchangeably. Be sure to plug the mouse connector into the MOUSE port, or you may damage your system.

Your computer also includes two removable panels above the mouse and keyboard ports providing access to a game port on the main system board and to one on an option card, if you installed one. You can enable the main system board game port via a jumper; see Chapter 3.

1-4 Setting Up your System

Connecting the Power Cord

Follow these steps to connect the power cord:

Plug the power cord into the power inlet on the back panel of the computer.

WARNING

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

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

After you connect the components of your system, you are ready to turn on the power.

Turning Your System On and Off

Before you turn on your system, be sure to read the Important Safety Instructions at the beginning of this manual.

Caution

If there is a protective card in a diskette drive, remove it now or you may damage your drive.

First turn on the monitor, printer, and any other external devices connected to the computer.

Now follow the instructions below to configure your system

1-6

Running the SETUP Program

Be sure to run SETUP the first time you use your computer, so you can verify or update the configuration information. You

also may need to run SETUP 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

Green PC options, such as the time intervals before the system and the hard disk drive go into low-power standby

mode.

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.

Setting Up your System 1-7

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 <F1> 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 table below lists the keys you can use to perform SETUP operations.

Whenever you are in SETUP, the bottom of the screen lists the keys you can press to perform specific functions.

The System Setup Option

From the System Setup screen, you can set the options described below.

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.)

Setting the video display type

The Video Systemoption allows you to define the type of display adapter you are using. If you connected your monitor to the computer’s built-in VGA port, select EGA/VGA.

Setting Up your System

1-9

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. Also make sure you disabled the on board VGA controller by setting jumpers J14 and J15 to the Off position. (See Chapter 3 for instructions.)

Checking system 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 3 to locate the SIMM sockets.)

Setting the diskette drive type(s)

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

drive installed in your computer. 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.

The Fixed Disk Setup Option

The options on the Fixed Disk Setup screen define the types of

hard disk drives you installed in your system. From this screen,

select Fixed Disk 0 Control or 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.

1-10 Setting Up your System

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 Disk option is highlighted 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. 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.

The Advanced System Setup Option

When you select this option from the Main Menu, you see the Advanced System Setup screen, which contains the options

described below.

Your system can automatically configure the Advanced System Setup options for you. To avoid configuration

problems, you should let the system configure these options.

However, if you connected a scanner or a parallel port network adapter to your parallel port, be sure to select Advanced Chipset Control so you can change the operation of the parallel port to PS2 mode (for bidirectional operation). See page 1-13 for more information.

Setting Up your System 1-11

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.

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.

1-12

Setting Up your System

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.

However, if you connected a scanner or a parallel port network

adapter to your parallel port, you should set Auto Configuration to Disabled so you can change the

Printer Port Control option to PS2 mode (for bidirectional operation). The default setting for the parallel port is AT mode (for unidirectional operation).

Setting the Boot Options

When you select Boot Options from the Main Menu, you see the Boot Options screen, which contains the options described below.

Selecting the drive boot sequence

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 :

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:

computer tries to load the operating system from drive C only.

Setting Up your System

then A:, the

only, the

1-13

Setting the floppy seek option

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.

Disabling the SETUP prompt

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.

Disabling power-on diagnostic error messages

The Pause on POST errors option allows you to disable the error message and the message Press <F1> 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.

Disabling the system summary screen

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 1-19.)

1-14

Setting Up your System

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, which contains the options described below.

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.

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.

Setting Up your System 1-15

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.

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 5.

Using the virus protection features

Several options on the Security and Anti-Virus screen allow you to define system protection features.

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 to your system. You can restrict diskette access only if passwords are enabled and you have enabled the Password on boot option.

the Diskette Access option, you can access the diskette

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.

You can also protect your system by selecting Write

protect for the Fixed disk boot sector option. When this option is enabled, the system displays an error message when a program tries to write to the boot sector of your hard disk drive. To use a legitimate program (such as the

MS-DOS@ FORMAT command) you must disable the write protect option.

Two additional options on this screen allow you to define time

intervals for the system to display a prompt asking whether you have performed your scheduled virus check or your

scheduled backup for your hard disk drive. You can disable these prompts or have them display Daily, Weekly, or Monthly. If you respond that you have not performed these functions, however, the system still starts normally.

Using the Green PC Features

The Green PC options allow you to define how the energy-saving features of this Energy Star compliant system will work for you. The options on the Green PC Features screen allow you to disable the energy-saving feature or set time-out periods to put the system and hard disk drive in a low-energy standby mode.

The Inactivity Timer 1 option sets the time-out period for video signals to your monitor. When the mouse or

keyboard has been inactive for the time period you select here, your computer stops sending video signals to your monitor. If your monitor is also Energy Star compliant, it goes into a

low-power standby mode because it isn’t receiving video

signals from your computer. Screens on monitors that aren’t

Energy Star compliant will go blank when your system is in

standby mode.

If you select a time period for the Lockout Timer as well as

the Inactivity Timer 1 option, the system won’t accept your keyboard input for the specified period of time after your

system has returned to an active mode. This allows time for your monitor to return to full power also.

The Fixed Disk Timeout option determines the time-out

period for your hard disk drive. The hard disk drive goes into a

low-power standby mode when the mouse and keyboard have

been inactive for the period of time you’ve indicated.

Note

Some hard disk drives do not support a low-power standby mode. Also, the delay caused by the hard disk drive returning to active mode may cause errors in some

applications. If you have problems, you may want to disable the Fixed Disk Timeout option.

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 1-14 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 Main Menu, you can do the following:

Using Your Computer

This chapter briefly describes the following operations:

Working comfortably

Stopping a command or program

Resetting the computer

Using energy wisely

Using the Green PC features

Changing the processor speed

Working Comfortably

This section provides some tips for creating 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. A chair with padded armrests lets you rest

your arms as you work.

Using your Computer

2-1

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.

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.

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.

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.

Stopping a Command or Program

You may sometimes need to stop a command or program while it is running. If you have entered an MS-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.

2-2 Using Your Computer

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 normally. If you reset the computer without properly exiting a program, you may lose data.

Also do not remove a diskette or reset or turn off the

computer while a diskette drive light is on. You could lose

data. Be sure to remove all diskettes before you turn off the

computer.

To reset the computer, press Ctrl Alt Del. The screen displays nothing for a moment and then the computer reloads your operating system.

You can also press the RESET button located in the upper right corner on the front of your computer.

If resetting the computer does not correct the problem, you probably 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, insert the system diskette in drive A. Then turn on the computer.

Using your Computer 2-3

Using Energy Wisely

By purchasing this low-power, Energy Star compliant computer, you join a growing number of users concerned about conserving energy. Here are a few additional tips you can use to be even more energy-wise:

If your printer and monitor aren’t Energy Star compliant, turn them off when you’re not using them.

Use your software’s print preview option (if available) before you print something. You’ll be able to catch formatting errors before you commit them to paper.

If you have an electronic mail system available to you, send E-mail rather than memos. Not only is this faster, but you’ll

save paper and storage space too.

Use recycled paper whenever you can

Using Your Green PC Features

Your computer places the system, the hard disk drive, or both into a low-power standby mode when the keyboard or mouse has been inactive for the time periods you select in SETUP. See

Chapter 1 for information on setting these values.

When your system is in standby mode, the Num Lock light on your keyboard flashes and your screen is blank. Press any key or move the mouse to resume activity.

If the hard disk drive is in standby mode, it doesn’t return to

active mode until you access it. You’ll hear it start again. It will take a second or two to reach its operating speed and read or write to the disk. The hard disk drive access light turns on when the system begins accessing the disk.

2-4 Using Your Computer

Note

Some hard disk drives do not support a low-power standby mode. Also, the delay caused by the hard disk drive returning to active mode may cause errors in some applications. If you have problems, you may want to disable the standby mode for the hard disk drive.

Changing the Processor Speed

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

slow (8 MHz). The slow speed is available to provide compatibility with older application programs, such as those that require you to leave a key disk-the diskette that contains the copy protection-in the diskette drive.

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

on the front panel is on. When the computer is operating at

slow speed, the light is off.

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 application software manual to determine if this is the case.

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 --. (Press the --key on the

numeric keypad.)

To select fast speed, press Ctrl Alt +.

The speed setting remains in effect until you reset your

computer or turn it off.

Using your Computer 2-5

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.

Installing and Removing Options 3-23

Note that your microprocessor socket may not look exactly like

the one illustrated here. If you’re not sure how to install your new processor, contact the EPSON Connection and ask for assistance.

Replacing the Processor Chip

Follow these steps to replace the processor chip :

Use the illustration on page 3-5 to locate the microprocessor

on the system board. The microprocessor chip may be inserted in a ZIF (Zero Insertion Force) socket.

Caution

Make sure you ground yourself by touching the metal surface on the inside of the computer’s back panel 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 it only by the edges of its case.

If there are any option cards in your way, remove them. See

page 3-17 for instructions.

Open the ZIF socket by lifting up the ZIF handle. The handle rests under a plastic tab. Press the handle down and away from the tab; then rotate the handle upward. This releases the chip from the socket. The illustration on the next page

shows this handle in the released position.

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

Note

The 486SX/25 microprocessor may be soldered onto an adapter board that is seated in the socket. Remove the adapter board as described above.

3-24 Installing and Removing Options

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.

Position the processor chip over the socket, aligning the notched edge of the chip (marked with a dot) with pin 1 on the socket, as shown below.

dot

pin 1

Caution

If you install the processor chip in the wrong orientation, you may damage the chip and void your warranty.

Make sure the pins in the processor chip are directly over the holes in the socket. Then gently push the microprocessor

straight into the socket, pressing evenly on all sides.

If you are installing a 486 chip rather than a Pentium

OverDrive processor, you’ll see an extra row of holes

around the outside of the socket. The 486 chip does not

occupy the outside row of holes.

Installing and Removing Options 3-25

Secure the processor chip by pressing the ZIF handle back to

the closed position.

Check the settings ofjumpers J11 and J13 to be sure they are

correct for the type of microprocessor you installed. You may also need to change the setting of jumper J17 to match the microprocessor type and operating speed.

If you installed a microprocessor with a different voltage

(check the table on page 3-23) you need to change the

settings ofjumpers J31 and J33. See pages 3-6 and 3-7 for

information on all these jumper settings.

10. If you are upgrading to a DX/ 40, DX/ 50, DX2, DX4, SX2, or Pentium OverDrive processor, you must install a heat sink and/or a fan, depending on the brand of processor you installed. See the table on page 3-23 for more information. Follow the instructions included with the heat sink if you

need to install one. If the heat sink comes with a fan, install

it using the instructions that came with the heat sink and

fan kit.

11. If you removed any option cards, replace them now; see

page 3-15 to replace a full-length card or page 3-16 to replace a half-length card.

12. Run SETUP as described in Chapter 1 to update your computer’s configuration with the new microprocessor

Make sure the jumpers on the hard disk drive are set correctly.

See the documentation that came with the drive for more

information.

You ate unable to store data on the hard disk drive.

If the hard disk drive has been in low-power standby mode,

make sure the drive has had time to achieve its full operating

speed before you try to write data to it.

If your drive was not configured, make sure you have

partitioned and formatted it correctly for your operating

system. See your operating system manual for instructions.

Also, make sure your hard disk drive has been physically formatted by the manufacturer. (All EPSON-supplied drives

are physically formatted at the factory.) If it has not been

physically formatted, use the format utility that came with the

drive to format it before you partition it or install the operating system. (Note that a physical format is different from software-based formatting commands, such as the MS-DOS FORMAT command.)

Troubleshooting
