Introduction

Your Epson® ExpressStation™ computer is powerful, versatile, and ideally suited for use as a network node and a highperformance personal workstation. It incorporates the latest EISA (Extended Industry Standard Architecture) technology into a highly-integrated, low profile desktop design. Its built-in features include a LAN (Local Area Network) controller, SCSI

(Small Computer System Interface) subsystem, and a highresolution VGA display adapter. The ExpressStation can use the most advanced devices and software available while maintaining full compatibility with ISA technology.

System Features

Your computer includes many useful features to improve the speed, security, and expandability of your system. Some of these features are listed in the sections below.

Built-in Interfaces and Subsystems

Memory and Caching Features

External ROM BIOS information can be shadowed into the

faster RAM area to speed up performance

Video BIOS memory can be copied to two different

memory addresses to provide compatibility with certain older application programs

System base memory can be set to 512KB to enable use of addresses between 512KB and 640KB by option cards that need that address space

Caching of all system memory can be enabled or disabled or specific memory blocks can be excluded from caching.

Software

Your system comes with four diskettes (Reference, VGA Utilities 1 and 2, and SCSI/LAN Utilities) containing the following software:

EISA System Configuration program System diagnostics program MS-DOS@ LAN drivers for the built-in LAN adapter

MS-DOS SCSI drivers for the built-m SCSI subsystem

MS-DOS VGA software drivers and utilities to provide high resolutions and various mode selections when using

the built-in VGA adapter

Hard disk drive low-level formatting utility.

In addition, your system BIOS includes a SETUP program for configuring your system without any option cards.

6 Introduction

Chapter 1

Using Your Computer

This chapter describes the following operations:

Locking the computer’s cover

It Using the password features and locking the keyboard U

Changing the processor speed

Controlling the speaker.

Locking the Computer’s Cover

You can lock the cover onto the computer to prevent unauthorized users from accessing its internal components. To do this, you need a padlock that fits through the holes in the lock block on the computer’s back panel. When the padlock is in place, the screw securing the cover on the computer cannot be removed.

You can also secure the computer to your work surface by

inserting a cable lock through the lock block holes and then through a secure anchor on your desk or table.

Using Your Computer

1-1

To lock the cover, insert a padlock or cable lock through the holes on both sides of the lock block.

To unlock the cover, remove the padlock or cable lock to expose the cover retaining screw.

Using the Password Features

You can set three types of passwords to provide security for your computer:

Power-on password

Network password

Keyboard password.

The power-on password prevents unauthorized users from using your system by requiring you to enter the correct password every time you turn on or reset the computer.

1-2

Using Your Computer

The network password modifies the way your power-on password works by allowing your computer to load your operating system and network software before requiring you to enter the correct password. This enables your system to connect to the network, while preventing unauthorized users from typing anything at the keyboard.

The keyboard password allows you to temporarily lock the keyboard without having to reset the computer. This secures your system when you will be away from it for a while. If you set a power-on password, it automatically becomes your keyboard password as well. However, you can set a different keyboard password or set a keyboard password without setting a power-on password.

Follow the instructions in the sections below to set, enter, change, or delete the different types of passwords.

Setting Passwords

There are two ways to set a power-on password:

Using the BIOS SETUP program

Using the EISA System Utilities.

To set a power-on password in SETUP, follow the instructions in the Select the Password option on the second page of SETUP options and follow the instructions on the screen to set a password.

You must run the EISA System Utilities to set a network and keyboard password, but you can also use it to set a power-on password.

To deactivate a network password, follow the steps above, but select De-activate Network Password instead. If you want to set a different keyboard password, see the next section.

Setting a keyboard password

Once you set a power-on password, it automatically becomes your keyboard password as well. If you want to use a different password for the keyboard, you can set one with the Set Keyboard Password option. This password takes effect only temporarily, however; when you turn off your computer, the power-on password again becomes your keyboard password.

You can also set a keyboard password without setting a power-on password, but when you turn off your computer or press the reset button, it erases the keyboard password.

Changing the Processor Speed

Your computer’s processor can operate at two speeds: high and low. High speed is the maximum speed of your microprocessor and low speed simulates an 8 MHz processor speed to provide compatibility with certain older application programs. (See your program manual to see if you need to set your processor speed to low.)

You set the default processor (or CPU) speed when you ran either the BIOS SETUP program or the System Configuration utility (described in your temporarily change the processor speed using keyboard commands or the EISA System Utilities program.

You must use the m or a key located on the numeric keypad. When you set the speed to low, you hear a low tone from the computer’s speaker; when you set it to high, you hear a high tone. The speed setting remains in effect until you press the reset button or turn off the computer, or until you change the setting.

Note

You can use these commands while you are running a program. However, if that program uses the command for another function, you cannot use it to change the processor speed. If this is the case, exit to your operating system command prompt and try the command or use the EISA System Utilities to change the speed, as described below.
