Where to Get Help If you purchased your computer outside the United States, please contact your dealer or the marketing location nearest you for customer support and service. International marketing locations are listed at the back of this manual.
Chapter 1 Setting Up Your System To set up your computer, follow the steps in this chapter. If you purchased additional options, see Chapters 4 and 5 for instructions on how to install them before you set up your system.
1 Choosing a Location When selecting a place to set up your system, choose a safe, convenient location that provides the following: q 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. q Good air circulation. Leave several inches of space around the computer so air can move freely. q Moderate environmental conditions.
Follow these steps to connect your VGA monitor to the computer’s built-in VGA port: 1. Place the monitor and computer so the backs are facing you. 2. 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 a power source). On most monitors, the monitor cable is permanently attached to the monitor, as shown in the following illustration. If your monitor does not have an attached cable, connect the cable to it now.
4. If the connector has retaining screws, tighten them. 5. Plug the monitor power cord into the monitor’s power inlet. monitor power inlet 6. Plug the other end of the power cord into an appropriate grounded electrical outlet or, if the cord has the correct type of plug, into the power outlet on the back of the computer. Caution Before you plug the monitor’s power cord into the back of your monitor, make sure the monitor’s power requirements do not exceed 1 Amp.
3 Connecting a Printer or Other Device Your computer has one parallel and two serial ports. To connect a printer or other peripheral device, follow the instructions below. Using the Parallel Port Follow these steps to connect a parallel printer to your computer: 1. Place the printer next to the computer so that the backs are facing you. 2. Align the connector end of the printer cable with the PARALLEL port, as shown below, and plug it in. If the connector has retaining screws, tighten them.
3. 4. 2-6 Connect the other end of the cable to the printer as shown below. 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 an appropriate grounded (earthed) electrical outlet.
Using the Serial Ports If you have a printer, a modem, or other peripheral device with a serial interface, you can connect it to one of the serial (RS-232C) ports on the back of the computer. These ports use a DB-9P connector, so be sure you have a compatible cable. To connect a serial device, insert the connector into one of the ports, marked SERIAL 1 and SERIAL 2. If you are connecting only one serial device, use the SERIAL 1 port, as shown below.
4 Connecting the Keyboard To connect the keyboard, hold the cable connector so the arrow on the connector faces up. Insert it into the port marked K/B, as shown below. Caution Although the connectors and ports for the keyboard and mouse are physically identical, they cannot be used interchangeably. Be sure to plug the keyboard connector into the keyboard (K/B) port or you could damage your system.
You can change the angle of the keyboard by adjusting the legs on the bottom. Turn it over and flip each leg upward until it locks into place. It is important to select the best angle so you will prevent wrist fatigue. (You may even want to purchase a wrist pad-sold at computer stores-for further comfort.) To lower the keyboard, press each leg back into its slot.
To connect the mouse to the built-in mouse port, plug the connector into the port marked MOUSE, as shown below. 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. If your system has not already been configured, you may need to install a mouse driver. See your mouse manual for instructions.
6 Connecting the Power Cord Follow these steps to connect the power cord: 1. Plug the power cord into the AC power INLET on the back panel, as shown below. WARNING To avoid an electric shock, be sure to plug the cord into the computer before plugging it into the wall outlet. 2. Plug the other end of the power cord into an appropriate grounded (earthed) electrical outlet.
7 Turning On the Computer After you set up your system, you’re ready to turn on the power. Check the following safety precautions to avoid accidentally damaging your computer or injuring yourself: q Do not connect or disconnect any peripheral device cables (including the mouse or keyboard) or power cables unless the computer power is off. q Never turn off or reset your computer while a disk drive light is on. This can destroy data stored on the disk.
4. To turn on the computer, press the power button on the right side of the front panel. The power indicator on the left side of the front panel lights up. After a few seconds, the screen displays a count of the system memory, and then the computer performs a power-on diagnostics routine to make sure everything is working correctly. 5. 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 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 this message. If MS-DOS@ is already installed, you may see the command prompt (C : \) or the menu screen of a program such as Microsoft Windows. Now you need to run SETUP to make sure your computer is configured properly. First turn off the computer, as described below, then see Chapter 2 for instructions.
Chapter 2 Running the SETUP Program The first time you use your computer, you need to run the SETUP program to define how your system is set up. You may need to run it again later if you change your configuration. SETUP is stored in the computer’s read-only memory (ROM), so you can run it any time you turn on or reset your system.
The configuration you define through SETUP is stored in a special 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. Whenever you reboot the computer, it checks the settings, and if it discovers a difference between the information in the CMOS RAM and its actual hardware configuration, it prompts you to run SETUP.
Starting the SETUP Program To start SETUP, make sure there is no diskette in the diskette drive; then turn on your computer. (If your computer is already on, turn it off, wait 20 seconds, and then turn it on again.) After the self test, you see the following prompt at the bottom of the screen: Press if you want to run SETUP As soon as you see this message, press .
Entering SETUP Options You can verify or change all SETUP functions except the password option from menu option 2, Run SETUP. To select this option, press to highlight it, then press . YOU see the SETUP screen. This screen displays the size of both the base and extended memory and whether a math coprocessor is installed. You also see a calendar for the current month at the bottom right of the screen. Additionally, this screen contains system parameters you can change.
Setting the Date and Time The real-time clock in your computer continuously tracks the date and time-even when the computer is turned off. Once you set the date and time using SETUP, you should not need to change them, unless you need to adjust the time for daylight savings or other seasonal adjustments. (The computer automatically changes the date for leap years.) Use the cursor arrow keys to position the cursor over the portion of the date or time you want to change. Press or to modify the date or time.
Setting the Hard Disk Drive(s) The SETUP program lets you select the type of hard disk drive(s) installed in your computer. If you have two hard disk drives, the first one is C and the second one is D. Be sure to choose the correct setting for both drives. Follow these guidelines: q If your system does not have a hard disk, select None for drives C and D. If you have only one hard disk drive, select None for drive D. q If you installed a SCSI drive, select None for drive D.
Hard Disk Drive Types The following table lists the types of standard hard disk drives you can use. Check this table and the documentation supplied with your hard disk to find the correct type number for your drive. If none of the types listed matches your drive, see “Defining Your Own Drive Type” on page 2-9.

Setting the Processor Speed The System speed option lets you set the default speed for your system. When you select Fast, your system operates at your processor’s highest speed, such as 25,33, or 50 MHz. The Slow option simulates an 8 MHz processor to provide compatibility with older application programs. At fast speed, your system can access memory faster, so your programs work faster. Select Fast unless you are using an application program that requires the slower speed. Check your program manual.
Setting the Diskette Seek Parameter If you enable the Diskette seek test option, the system checks for a diskette drive during its power-on diagnostics. If no diskette drive is connected, you see a diskette drive error. Disable this option if you want your system to boot when no diskette drive is connected. Using the SETUP Screen Submenus The SETUP screen contains three submenus that allow you to change these settings: q Shadow ROM options q Keyboard options q Peripheral options.
Four additional shadow options allow you to shadow 32KB at the memory addresses listed on the screen. You may want to enable one or more of these shadow options if, for example, you are using option cards that contain ROM. You can shadow the memory on the card to your system’s RAM using these options. Check the memory map on page A-6 and the documentation that came with your option card to determine which addresses your option card can access.
Setting the Peripherals Options The Peripherals setup option lets you change the settings for the built-in interface ports and disk drive controllers. You may need to change these settings if you install an interface on an option card. The following table lists the possible settings.
Setting the Password Options SETUP lets you enter a new password or disable an existing password to control who can access your system. A second password option allows you to set a hot key to disable your keyboard and mouse until you enter your system password. Entering a Password Follow these steps to enter a password: 1. Select option 3, Set Password options, from the main menu. 2. Press until you see New Install displayed for the Password state option.
Changing or Deleting a Password If you want to change your password, follow the same steps as to enter a new password. When the cursor is at the Enter password option, type the new password you want to use. To delete a password, select Not Installed for the Password state option. Whenever you delete your password using SETUP, make sure you save the new settings as you exit the SETUP program.
Using the System Board Help Function SETUP provides a system board help function that contains a diagram of your system board in addition to the following information: q DIP switch settings q Jumper settings q Identification of connectors q Correct SIMM configurations q External cache configurations q Hard disk drive types q System key combinations. To use this help function, select option 4, Display system board help, from the main menu. Use the arrow keys to scroll through the options.
Saving Your Settings and Exiting SETUP When you leave SETUP, you can either save the settings you have changed or exit the program without saving any changes. To save your settings, follow these steps: 1. Press to return to the main SETUP menu. 2. Select option 6, SAVE settings and exit, and press [Enter. You see this message: Write to CMOS RAM and exit (Y/N)? 3. Press and The system reboots. 4. If you have just run SETUP for the first time, see “Post-SETUP Procedures,” below.
Post-SETUP Procedures If you have just run SETUP for the first time and your system has not been configured, you now need to install the operating system on your computer. See your operating system manual for instructions. After you have installed your operating system, you can install any software you plan to use. See your application program manuals for instructions.
Chapter 3 Using Your Computer This chapter briefly describes the following operations: q Working comfortably q Using disks and disk drives q Using special keys on the keyboard q Stopping a command or program q Resetting the computer q Using a password q Using the hot key feature q Changing the processor speed. Working Comfortably This section provides tips for creating a comfortable work environment.
Sitting at Your Computer When you use the computer, try to keep your elbows, hips, and knees bent at approximately 90 degree angles and keep your wrists as close to horizontal as possible. (Your hands, forearms, and thighs should be horizontal and your upper arms and lower legs should be vertical.) Your feet should rest firmly on the floor or a footrest. An adjustable chair allows you to customize your workstation for your body so you can maintain the right posture.
Work in a relaxed, natural, upright position and let the chair support you. Your elbows should be near your body and level with or slightly lower than the keyboard so your hands rest lightly on the keys. To help you keep your wrists straight, the slope of the keyboard should be no more than 25 degrees. Try not to hit the keys too hard; using too much force creates tension in your hands.
Positioning and Viewing the Monitor Place the monitor directly in front of you and sit about an arm’s length away from it. To minimize glare and reduce eye fatigue, position the monitor so that sunlight, desk lamps, and overhead lights do not shine directly on the screen. When you are sitting in front of the monitor, the top of the screen should be slightly below eye level so you look down, rather than up, at the screen.
Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use your stored data. This section tells you how to: Choose the right diskettes for your drive Write-protect diskettes Insert and remove diskettes Use a single diskette drive system Format diskettes Make backup copies Care for diskettes Use a hard disk drive. Types of Diskette Drives Your system supports the following types of diskette drives: q 1.44MB, 3.5-inch q 1.2MB, 5.
Note MB stands for megabyte, which equals 1024KB (or 1,048,576 bytes). KB stands for kilobyte, which equals 1024 bytes. Each byte represents a single character, such as A, $, or 3. If your computer has more than one type of diskette drive, or if you use different types of diskettes, you need to be aware of certain incompatibilities between the drives and diskettes. See the following tables. 3.5-inch drive/diskette compatibility Drive type Diskette types it can read from and write to 720KB 720KB 1.
Write-protecting Diskettes You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can read it and copy data from it, but you cannot store new data on it or delete any files it contains. On a 3.5-inch diskette, the write-protect device is a small switch on the back of the diskette in the lower right corner, shown below. To write-protect a 3.
To write-protect a 5.25-inch diskette, cover the small, rectangular notch (shown below) with an adhesive write-protect tab. Write-protect tabs usually are included in a new package of blank 5.25-inch diskettes. To remove the write protection, peel off the write-protect tab. Some program diskettes have no switch or notch so they are accidentally erased or altered.
Insertting and Removing Diskettes 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. 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.
Using a Single Diskette Drive System Most operating systems expect the computer to have at least two diskette drives and display prompts and messages accordingly. MS-DOS, for example, recognizes the first diskette drive (the top drive) as drive A and a second diskette drive as drive B. If you have only one diskette drive, MS-DOS can treat it as both A and B when you need to perform operations that normally would use two diskette drives.
Formatting Diskettes Before you can store data on a new diskette, you must format it. Formatting prepares the diskette so that the operating system can write data on it. You need to do this only once, before you use the diskette for the first time. You can also reformat previously used diskettes to store new data. This process erases all the data on the diskette, so be sure you do not want to save any of the files on a used diskette before you format it.
Caring for Diskettes Follow these simple precautions to safeguard your data and lengthen the life of your diskettes: q Avoid leaving diskettes near magnetic fields that can erase the data, such as those generated by electric appliances or cordless telephones. Never place a diskette on top of your monitor or near the hard disk drive.
Most operating systems let you keep related files together in directories and subdirectories so they are easy to find and use. See your operating system manual for instructions on managing your files and directories. Note A hard disk must be partitioned and formatted before you can use it. Be sure you have performed the procedures described in your operating system manual to prepare your hard disk for use.
Special Keys on the Keyboard Certain keys on your keyboard serve special functions when your computer is running your operating system or application programs, as described in the table below.
Special key functions (continued) The and key work as toggles; press the key once to turn on a function and again to turn it off. When the function is enabled, the corresponding light in the upper right corner of the keyboard is on. Stopping a Command or Program You may sometimes need to stop a command or program while it is running.
Resetting the Computer Occasionally, you may want to clear the computer’s current settings or its 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.
Using a Password If you set a system access password when you ran the SETUP program, you must enter it every time you turn on or reset the computer. Follow these steps to use your password: 1. If you do not have a hard disk, insert your system diskette in drive A. 2. Turn on or reset the computer. You see the following prompt: Enter Password: 3. Type your password and press After you type the password correctly and press the computer loads the operating system and displays the command prompt.
2. When you want to disable the keyboard and mouse, enter your hot key combination. The keyboard and mouse lock up and do not respond to typed entries or mouse movement. 3. To resume activity, type your password and press . Changing or Deleting a Password To change or delete your password, you must run the SETUP program and follow the instructions for entering a password in Chapter 2. If you do not know your password, see “Password Problems” in Chapter 6.
If you want your computer to always start at slow speed, you can change the default setting through SETUP. See Chapter 2 for instructions. 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.
Chapter 4 Installing and Removing Options You can enhance the performance of your computer by adding optional equipment such as memory modules, option cards, an Intel OverDrive processor or math coprocessor, or video memory. This chapter describes how to install (and remove) these options, as well as how to change the jumper and DIP switch settings inside the computer. You may need to change these settings if you install options or if you want to change the way your system operates.
How to Use This Chapter This chapter explains how to do the following: q Remove and replace the computer’s cover q Change jumper settings and DIP switch settings on the main system board q Install and remove memory modules (SIMMs) q Install and remove an option card q Remove and replace the option card connector board q Install a new processor chip q Increase the video memory q Use the VGA feature connector q Replace the system battery.
Locating the lnternal Components As you follow the instructions in this chapter, refer to the following illustration to locate the different components inside your computer.
Removing the Cover You need to remove the computer’s cover to install any of the options described in this chapter or to install or remove a disk drive (as described in Chapter 5). Follow these steps: 4-4 1. Turn off the computer and then any peripheral devices (including the monitor and printer). 2. Disconnect the computer’s power cable from the electrical outlet and from the back panel. Also disconnect any cables that are connected to the computer, including the keyboard and mouse cables. 3.
5. From the front of the computer, grasp the sides of the cover and pull it straight toward you until it stops, just before it reaches the front of the computer. Then lift it off at an angle as shown below. 6. Set the cover aside. 7. Ground yourself to the computer by touching the metal surface of the back panel. WARNING Be sure to ground yourself by touching the back panel of the computer every time you remove the cover.
Changing the Jumper and DIP Switch Settings The main system board in your computer has a number of jumpers and DIP (Dual Inline Package) switches. These devices control the operation of your system and provide configuration information to your CMOS ROM. The jumpers control the following functions: q Enable or disable the built-in VGA display adapter q Specify the type of CPU installed q Specify the amount of external cache.
Display adapter and CPU jumper settings Jumper Setting Function J3 A* B Enable the built-in VGA adapter Disable the built-in VGA adapter so you can use a display adapter on an option card as your primary adapter J4 A* * B Select DX or DX2 CPU Select SX CPU * Factory setting ** Factory set according to system CPU External cache jumper settings * Factory setting; change jumpers only if external cache chips are installed by servicer DIP switch settings Switch 1 ** Setting Function O N O F F 3
Setting the Jumpers If you need to change any jumper settings, follow these steps: 1. Refer to the illustration on page 4-3 to locate the jumpers, 2. If there are any option cards installed, and you want to change the setting for jumper J3, you may need to remove the cards. See page 4-19. 3. A jumper’s setting is determined by where the jumper is placed on the pins. For three pin jumpers, the jumper connects pin 1 and the middle pin (position A) or pin 3 and the middle pin (position B), as shown below.
Setting the DIP Switches If you need to change any of the DIP switch settings, follow these steps: 1. Locate the DIP switch block near the center of the system board, shown on page 4-3. The switches are numbered 1 through 5, and the ON position is marked on the block. 2. Use a pointed instrument, such as the tip of a pen, to turn a DIP switch on or off. The new setting takes effect the next time you turn on the computer. 3. Depending on which DIP switch you change, you may also need to run SETUP.
Memory Modules (SIMMs) Your computer comes with 4MB of memory installed on the system board. By installing memory modules-also called SIMMs-you can increase the amount of memory in your computer up to 36MB. There are two SIMM sockets on the main system board, and each can contain one memory module. You can install SIMMs with a capacity of lMB, 4MB, or 16MB.,The following table shows the possible SIMM configurations; do not install memory in any other configuration.
Before you install SIMMs, check the following guidelines to ensure that they will work properly: q Use only 36-bit, 72-pin, fast-page mode SIMMs that operate at an access speed of 70ns (nanoseconds) or faster. Be sure all the SIMMs operate at the same speed. q Your computer can use any SIMM that complies with industry standards; however, it is best to use Epson SIMM option kits to ensure reliability and compatibility. lnserting SlMMs Follow these steps to install SIMMs: 1.
4. Push the SIMM into the socket until it is seated firmly in the slot. Then tilt it upright, as shown below, guiding the hole at each end of the SIMM over the retaining post at each end of the SIMM socket.

A display adapter card that can generate up to 25 lines of text with 80 characters on each line, two-color graphics at 640 x 200 resolution, or four-color graphics at 320 x 200 resolution. Chip A piece of silicon containing miniature transistors and resistors wrapped in insulating material. Chips process electrical signals sent to them and then transmit the processed signals to the computer system. Also called an integrated circuit. See also CPU.
Conventional memory The memory in the computer below 1MB that is available to MS-DOS and application programs-usually 640KB. Also called base memory or main memory. Coprocessor See Math coprocessor. Copy-protected program A program containing a software “lock” that prevents it from being copied. See also Key disk. CPU Central Processing Unit. The primary device that interprets instructions, performs tasks, keeps track of stored data, and controls input and output operations. See also Microprocessor.
Device A piece of equipment that is part of a computer system, such as a disk drive, a monitor, or a printer. Device driver A file containing instructions that allow your computer to recognize and communicate with a device. The device may be a printer, monitor, or other type of device. Diagnostics See Power-on diagnostics, DIP switch Dual Inline Package switch. A small rocker- or sliding-type switch that controls a particular function. Directory A group of files stored in a particular area on a disk.
Double-density A type of diskette format that allows you to store twice as much data as the standard-density format. A 3.5-inch, double-density diskette can store 720KB of data. A 5.25-inch, double-density diskette can store 360KB of data. EGA Enhanced Graphics Adapter. A display adapter card that allows you to display high-resolution graphics on an EGA monitor.
High-density A type of diskette format that allows you to store more data than on single- or double-density diskettes. A 5.25-inch, high-density diskette can store 1.2MB of data. A 3.5-inch, high-density diskette can store 1.44MB of data. IDE Integrated Drive Electronics. A type of hard disk drive interface in which the controller is on the drive instead of on a controller card. Your computer includes an interface on the main system board for up to two IDE hard disk drives.
LIM EMS 4.0 Version 4.0 of the Lotus/Intel/Microsoft Expanded Memory Specification-your computer’s capability to support programs that use expanded memory. See also Expanded memory. Main system board The circuit board inside your computer containing the circuitry and components your computer needs to operate. Math coprocessor A device that enables the computer to process mathematical calculations faster by using floating point numbers instead of whole numbers.
Memory module A small circuit board, commonly called a SIMM (single inline memory module), that contains surface-mounted memory chips. You can add memory modules to the main system board to expand your computer’s memory. MGA Multi-mode Graphics Adapter. A display adapter card that can display monochrome text and color graphics. Microprocessor A small CPU on one semiconductor chip. See also CPU. Modem MOdulator/DEModulator.
Numeric keypad The number and cursor control keys grouped together on the right side of the keyboard. The operation of the dual-use keys on the numeric keypad is controlled by the key. Operating speed The speed at which the computer’s processor can execute commands, usually expressed in megahertz (MHz). See also Megahertz. Operating system A collection of programs that manage a computer’s operations, such as interpreting input, managing files, and reading and writing data to disk.
Parallel An interface that transmits data simultaneously over separate wires in a cable. See also Interface and Serial. Parameter A qualifier added to a command that tells your operating system what data to process, where it should locate or store a file, or how it should operate. See also Switch. Pathname The directory name(s) you specify to locate a file. For example, the pathname for the file SALES, stored in the subdirectory BUSINESS, is \BUSLNESS\SALES.
Prompt A message displayed to request information or tell you what action to perform next. See also Command prompt. RAM Random Access Memory. The area of the computer’s memory used to run programs and store data while you work. All data in RAM is erased when you turn off or reset the computer. Read To gather data from one source (such as a disk) and transfer it to a device (such as a screen or a printer).
ROM Read Only Memory. Memory that can only be read and cannot be modified. ROM retains its contents even when you turn off the computer by using power from a backup battery. Root directory The main directory in a hierarchical disk directory structure. All other directories are subdirectories of the root directory. RS-232C A standard type of serial communication. You can connect an RS-232C device to either of the computer’s RS-232C serial ports.
System diskette A diskette that contains the operating system and can be used to boot the computer. Tape drive The physical device that allows you to insert large-capacity magnetic tape cartridges for compact data storage and backup. UNIX An operating system that supports multitasking and is especially suited to multi-user environments. UNIX is compatible with a range of computers, from personal computers to mainframes. See also Operating system. VGA Video Graphics Array.
