Chapter 1 Setting Up Your System This chapter briefly describes how to set up your computer. It includes the following information: Getting started Connecting the computer Running the SETUP program Post-SETUP procedures. 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.
Good air circulation. Leave several inches of space around the computer so air can move freely. 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.
Connecting the Computer Use the illustration below to locate the ports on the back of your system as you connect the keyboard, monitor, printer, and other devices. Connecting a Keyboard To connect a keyboard, hold the cable connector so the arrow on the connector faces up. Insert it into the port marked K/B. Connecting a Mouse Your system came with a serial mouse that connects to either of the computer’s built-in serial ports.
When you install the drivers for your mouse, make sure you identify the port to which you connected it. See the README file on the diskette that came with your mouse for more information. Connecting a Monitor The way you connect your monitor to the computer depends on the type of monitor you have. If you have a VGA monitor (or a multifrequency monitor with an analog connector), you can connect it to the computer’s built-in VGA port as described below.
6. Plug the other end of the power cord into an appropriate grounded electrical outlet or into the power outlet on the back of the system. 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 parallel and two serial ports. To connect a printer or other peripheral device, follow the appropriate instructions below.
Using the serial ports If you have a printer, a modem, or a mouse with a serial interface, you can connect it to one of the serial (Rs232C) ports on the back of the computer. Make sure you have a cable compatible with a DB-9P connector. To connect a serial device, insert the connector into one of the ports marked COM1 and COM2. If you are connecting only one serial device, use the COM1 port. Connecting the Power Cord Follow these steps to connect the power cord: 1.
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 parts of your system. 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 when the computer’s power is on. Never turn off or reset your computer while a disk drive light is on.
Follow these steps to turn on your system: 1. Turn your computer around so the front panel faces you. Place your monitor, printer, and other devices in a convenient arrangement. 2. If there is a protective card in the diskette drive, remove it now. 3. Turn on the monitor, printer, and any other devices connected to the computer. 4. 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 a count of the system memory.
Running the SETUP Program You need to run the SETUP program the first time you use your computer. If your system was configured for you, you may still need to set the date and time. If your system came unconfigured, you need to define how it is set up. You may need to run the program again later if you change your configuration. SETUP is stored in the computer’s ROM BIOS (read-only memory, basic input/output system), so you can run it any time.
Starting the SETUP Program You can run SETUP whenever you see the operating system command prompt, such as: C:\> or A:\> To start SETUP, hold down Ctrl and Alt, then press S. Also, whenever you start your computer, if the system detects an error in your system configuration, you will see the following message: Press the Fl key to continue, F2 to run the setup utility If you see this message, press F2 to run the SETUP program to correct your configuration.
Whenever you are in the SETUP program, the bottom of the screen lists the keys you can press to perform specific functions. Displaying System Information The SETUP program provides a system information screen that lists the following: Processor type Coprocessor type (if you’ve installed a 486DX microprocessor upgrade) Reserved memory BIOS version number Addresses for video mode, serial ports, and printer ports Option ROMs (if any ROM exists on your installed option cards).
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 on your system. 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. Note If you add a diskette drive and want to reassign the top drive as drive A, you must change jumpers J35, J36, J37, and J38, as described in Chapter 3. Then run SETUP to reassign drive types.
Hard disk drive types The table below lists standard hard disk drives. Check this table and your drive documentation to find the correct type number. If none of the types listed matches your drive, see page 1-15.
Hard disk drive types (continued) 1-14 Setting Up Your System
Defining your own drive type If the parameters for your hard disk (listed in its documentation) do not match any of the types listed in the table above, you can define your own type. Follow these steps: 1. Move your cursor to Hard Disk 1 or 2 and press + or until you see drive type 48 or 49. 2. Press to move the cursor to the Cyl field. 3. Type the appropriate cylinder value for your hard disk. The documentation that came with your hard disk drive will provide the appropriate information. 4.
Checking System Memory Your computer comes with 4MB of RAM on a SIMM. DOS and application programs that run under DOS use the first 640KB of memory. You can use the memory above 1MB as extended memory. When you boot your system, the system BIOS detects the type of RAM and updates the total memory size automatically. You see the memory configuration displayed in the Base Memory and Extended Memory fields on this SETUP screen.
Video display type options Setting Keyboard Options Two options in the SETUP program allow you to control keyboard settings: the Keyboard option and the NumLock on at boot option. For this system, the Keyboard option in the SETUP program has no effect. The NumLock on at boot option determines the initial state of the num lock function when you turn on or reset your system. When num lock is off, the keypad controls cursor movement. If num lock is on, the keypad types numbers.
Setting the Processor Speed The CPU Speed option sets the processor speed to fast or slow. At fast speed, your processor operates at its fastest speed (25,33, 50, or 66 MHz, depending on the speed of your microprocessor). At the slow speed setting, the processor operates at 8 MHz to provide compatibility with older application programs. Setting the Password The SETUP program lets you enter or delete an optional password to control access to your system.
Enabling an External Cache If you have installed external cache in your system, set the External Cache option to Enabled.You must also set your shadow video and BIOS options to Cacheable or WP-Shadow. Setting Shadow ROM Options Your computer can access RAM faster than ROM. Two options, Shadow BIOS ROM and Shadow Video ROM, allow your system to copy the contents of its system and/or video ROM into RAM (WP-Shadow) or external cache, if you have some installed (Cacheable).
Using Other Shadow Options Eight additional shadow options are available, allowing you to shadow 16KB at the memory address listed on the screen. You may want to enable one or more of these shadow options if you are using option cards that contain ROM. Using these options, you can shadow the memory on the card to your system’s RAM or external cache (if one is installed). Check the documentation that came with your option card to determine which addresses your option card can access.
Post-SETUP Procedures After you run SETUP for the first time, you may need to install the operating system on your computer. See your operating system manual for instructions. Once you have installed your operating system, install any software you plan to use. See your application program manuals for instructions. You may also want to install the optional extended video drivers for some of your application programs. See Chapter 5 for more information.
Chapter 2 Using Your Computer This chapter briefly describes the following operations: Inserting and removing diskettes Stopping a command or program Resetting the computer Using the password Changing the processor speed. 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.
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 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. Never remove a diskette or reset or turn off the computer while a diskette drive light is on. You could lose data, Also, remove all diskettes before you turn off the computer.
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. Do not reset the computer to exit a program.
Using a Password If you set a 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 operating system diskette in drive A. 2. Turn on or reset the computer. You see this prompt: PASSWORD PLEASE: 3. Type your password. You see an asterisk for each character you type. Then press Enter. 4.
Changing the Processor Speed Your computer’s processor can operate at two speeds: fast speed (the speed of your microprocessor) or slow speed (8 MHz). The slow speed is available to provide compatibility with older application programs. When your computer is operating at fast speed, the TURBO 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.
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. You can, however, change the processor speed through the SETUP program. The speed setting remains in effect until you do the following: Reset your computer Turn off your computer Change the speed with another keyboard command Change the speed setting in the SETUP program.
Chapter 3 Installing and Removing Options You can enhance the performance of your computer by adding optional equipment such as system, video, or cache memory modules, option cards, or a microprocessor upgrade.

Slide the mounting bracket toward the diskette drive bays, as shown above, until the slots clear the tabs. 3. 4-8 Lift the mounting bracket out of the computer and set it aside.
4. Align the hard disk drive so that the cables lead toward the diskette drive bays and the four holes at the base of the drive are above the four pegs, as shown below. 5. Gently lower the drive over the pegs. When the hard disk drive is resting on the pegs, it will not move from side to side. 6. Lower the mounting bracket over the hard disk drive, making sure that the slots in the mounting bracket fit over the tabs on the base of the computer.
7. Slide the bracket toward the side of the computer, as shown below, until the tabs hold the bracket in place. 8. Secure the mounting bracket with a screw on each side, as shown above. Installing the Hard Disk On the Mounting Bracket You can install a hard disk drive on top of the mounting bracket rather than under it. Refer to the illustration of the mounting bracket on page 4-8 and the one below while following these steps: 1.
2. Lift the mounting bracket out of the computer. 3. Turn the hard disk drive over and locate the four mounting holes on the drive. 4. Position the bracket on the hard disk drive, aligning the holes in the bracket with the holes on the drive. 5. Secure the bracket to the drive with four screws.
6. Turn the drive and the mounting bracket over, then slide the slots in the mounting bracket under the tabs at the base of the computer until the tabs hold the bracket in place. Note If the drive does not fit within the internal bay, you can move the mounting frame toward the power supply and align only one set of the slots on the mounting bracket with the tabs on the computer. 7. 4-12 Secure the mounting bracket with the retaining screws.
Removing a Hard Disk Drive From the Internal Drive Bay To remove a hard disk drive, reverse the installation steps outlined above. Then disconnect the hard disk drive ribbon cable and the power supply cable from the back of the drive. When you disconnect the cables, grasp the connectors and pull them straight out so you do not bend the pins; do not pull on the cables. Use the screws to again secure the hard disk drive mounting bracket to the base of the computer.
Follow these steps to install a drive in the upper horizontal drive bay: 1. Remove the faceplate from the bay. Place your hand behind the plate through the hole in the drive bay, and push the faceplate forward, as shown below. Keep the faceplate in a safe place in case you remove a drive later. 2. 4-14 Remove any brackets or mounting frames from the drive. See page 4-3 for instructions.
3. 4. Slide the drive into the bay until it is flush with the front of the computer. Align the slots at the side of the drive bay with the mounting holes in the drive. Then secure both sides of the drive to the drive bay using the retaining screws.
Connecting the Drive and Power Cables To connect the drive to the computer, you need to connect both the drive ribbon cable and a power supply cable. Follow the steps below. 1. If you are installing a diskette drive, locate the diskette drive ribbon cable. (The connector in the middle of the cable is already connected to the system board.) 2. If you are installing a second diskette drive or a tape drive with a card-edge connector, one end of the cable is connected to the bottom diskette drive.
If you are installing a hard disk drive in the upper horizontal bay, make sure you use the proper hard disk drive ribbon cable and connect the ribbon cable to the hard disk drive connector. Also, if this is the second hard disk drive in your system, make sure you set the jumpers on both hard disk drives to indicate which is the master and which is the slave drive. See the documentation that came with your hard disk drive for instructions. 3.
If you installed a diskette drive in the upper bay, it is drive B; the lower drive is A. However, if you want to reassign the upper diskette drive as drive A, you can change jumpers J35 through J38. See Chapter 3 for instructions. Removing a Drive from the Upper Drive Bay To remove a drive from the upper drive bay, follow these steps: 1. Remove both the ribbon cable connector and the power cable connector from the drive. 2. Remove the screws securing the drive. 3.
2. Identify pin 1 on the drive and align the connector so that the red wire is at pin 1, as shown below. red wire 3. Locate the multi-colored power supply cable with the small connector. This cable is attached to the system board rather than the power supply. 4. Position the power supply cable connector so that the holes fit over all the pins. The red wire on the cable will align with pin 1 identified at the power connector on the circuit board of the drive.
Post-installation Procedures After you install or remove your drive(s) and replace the cover on your computer, you need to run the SETUP program to define the correct configuration for your newly-installed drive. See Chapter 1 for instructions.

Chapter 6 Troubleshooting If you have any problems as you set up and use your computer, refer to this chapter. You can correct most problems by adjusting a cable connection, repeating a software procedure, or resetting the computer. The troubleshooting suggestions in this chapter are organized in general categories, such as “The computer will not start.” Within each category, a more specific problem is described with possible solutions.
Use these guidelines to locate information about your system: 6-2 Serial number: Look on the back panel of the computer to see the serial number. Video BIOS version: Restart your system. You’ll see the video BIOS version number displayed on the screen when your system performs power-on diagnostics. System BIOS version: Start SETUP and display the System Information screen to see the system BIOS version number.
The Computer Will Not Start The power light is on, but the computer does not start. Replace your main operating system diskette and turn on the computer again. Caution If you turn off the computer, always wait at least 20 seconds before turning it back on. This prevents damage to the computer’s electrical circuitry. The computer does not start and the power light is not lit. Make sure the power cord is securely connected to both the AC inlet on the back panel and an electrical outlet.
You installed of removed system components, and now your computer does not start. Check to make sure you have reconnected all the internal and external cables correctly. You may have installed option cards that exceed the system’s power requirements. Check the power requirements in Appendix A. If you replace the microprocessor, make sure the processor chip and the oscillators are both installed correctly. Also make sure pin 1 on the chip or the oscillator is connected with pin 1 on the system board.
Keyboard Problems The screen displays a keyboard error message when you turn on of reset the computer. Make sure the keyboard is securely connected to the correct port. Nothing happens when you type on the keyboard. See “The Computer Does Not Respond,” above. The cursor keys on the numeric keypad do not work properly. If the Num Lock light in the upper right corner of the keyboard is lit, press NumLock to turn off the function.
If you installed a display adapter card, make sure your monitor and display adapter match. Also check to see if the card’s switches or jumpers are set properly. If your display adapter card is not VGA, make sure you have your service representative disable the system’s built-in VGA adapter for you.
Diskette Problems You see a diskette error message. Reinsert the diskette, making sure you insert it all the way. If the drive has a latch, turn it down to secure the diskette. Also, check to see that you have inserted the right type of diskette in the drive. For example, make sure you are not inserting a high-density diskette in a double-density drive. Reinserting the diskette does not solve the problem. Insert the diskette in another diskette drive of the same type.
Diskette Drive Problems A newly-installed diskette drive is not working properly. Make sure you have installed the drive correctly and check all the cable connections. You see a diskette drive error when you start your computer. Run the SETUP program and configure your system for the correct type of diskette drive. The diskette drive is making loud or unusual noises. Contact your service representative or Epson Direct. Hard Disk Drive Problems A newly-installed hard disk drive is not working properly.
You are unable to store data on the hard disk drive. Make sure you have partitioned and formatted the drive correctly for your operating system. Use the procedures provided in your operating system manual. 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.
Software Problems The application program does not start. Check that you are following the correct procedure for starting the program and that it is installed correctly. If you do not have a hard disk, make sure the correct diskette is in the diskette drive. If you need help, contact your software manufacturer. The application program is having trouble reading a key disk. You may be running an application that requires a slower processor speed.
The printer prints garbled information. Check the printer manual for the printer’s correct DIP switch or control panel settings. Also, make sure you have the proper drivers installed for your printer and make sure you’ve selected the correct printer within your software application. Option Card Problems A newly installed option card is not working correctly. Make sure the option card is installed correctly and is well-seated in its slot.
An external device connected to the option curd is not working correctly. Make sure you are using the proper cable to connect the device to the card. Memory Module Problems The memory count displayed by the power-on diagnostics program is incorrect. You may have installed the SIMMs incorrectly. They may be the wrong type or speed, or they may not be inserted all the way. See Chapter 3 for information on installing SIMMs.
Controller Problems You see a controller error for the hard disk drive controller or the I/O port controllers when you start your system. The indicated controller on your system board may be faulty. If you have an option card with a controller that will work with your device, you can install it and change the jumper settings on the system board to disable the built-in controller. You can then continue to use your system until it is convenient for you to have it serviced.
