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.)

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.

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.
