Chapter 1 Setting Up Your System This chapter briefly describes how to setup your computer. It includes the following information: Unpacking your computer Setting the voltage selector switch Connecting system components Turning the computer on and off Running the SETUP program Post-SETUP procedures.
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.
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, as shown below. Connecting System Components Use the following illustration to locate the ports on the back of your system as you connect the keyboard, monitor, printer, and other devices.
Your system also includes two removable panels above the mouse and keyboard ports providing access to the game port on the main system board and to an optional port. Connecting a Keyboard and Mouse To connect a keyboard, hold the cable connector so the arrow on the connector faces up. Insert it into the port marked K/B. If you have a PS/2 compatible mouse, insert the connector into the port marked MOUSE.
You must install a mouse driver if your system has not been preconfigured. See your mouse manual for instructions. (If you ® are using Microsoft Windows,™ the installation program automatically loads a mouse driver for Windows applications.) Connecting a Monitor If you have a VGA or SVGA monitor (or a multifrequency monitor), follow these steps to connect it to the computer’s built-in VGA port: 1.
Connecting a Printer or Other Device Your computer has one bi-directional parallel and two serial ports. To connect a printer or other peripheral device, follow the appropriate instructions below. Using the parallel port Follow these steps to connect a parallel printer to your computer: 1. Plug the connector end of the printer cable into the computer’s PARALLEL port. If the connector has retaining screws, tighten them. 2. Connect the other end of the cable to the printer.
Connecting the Power Cord Follow these steps to connect the power cord: 1. 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. 2. 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.
4. To turn on the computer, press the power button located on the right side of the front panel, as shown below. The power indicator lights up. After a few seconds, the computer displays a count of its system memory, and then performs its power-on diagnostics. This is a series of checks the computer runs each time you turn it on to make sure everything is working correctly. 5.
If your system is configured to automatically start Microsoft Windows or a word processing program, or has a different operating system, you will see the first menu or screen of that program displayed at this point. If your system is not configured to start like this, you will see the MS-DOS operating prompt, such as C:\ > or A: \>, each time you turn on the computer. Now follow the instructions below to configure your system using the SETUP program.
SETUP lets you verify or change the following: Current date and time Type of diskette drive(s) and hard disk drive(s) System memory Video display type Keyboard options Processor speed Internal cache function Shadow options Processor chip features Green PC features. SETUP is stored in the computer’s ROM BIOS, so you can run it any time. The configuration information is stored in an area of memory called CMOS RAM.
If the system detects an error in its configuration when you turn it on, you will see the following message: Press the F1 key to continue, F2 to run the setup utility If you see this message, press F2 to run SETUP to correct your configuration. The table below lists the keys you can use to perform SETUP operations. SETUP funtion keys Whenever you are in SETUP, the bottom of the screen lists the keys you can press to perform specific functions.
Displaying System Information When you press F2 from either of the SETUP screens, you will see a list of the following: Processor type Coprocessor type (if one is installed) Reserved memory BIOS version number Addresses for video mode, serial ports, and printer ports. Press any key to return to the SETUP screen. 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.
Setting the Hard Disk Drive(s) Your system comes with a hard disk auto-sensing feature that automatically detects the type of hard disk drive(s) installed in your computer. (See Appendix A for a list of hard disk drive types and their parameters.) The SETUP program allows you to view or change the parameters for your hard disk drive. If you are using an older drive or a preformatted drive, it may not support the auto-sensing feature.
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, follow these steps to define your own type 1. Move the cursor to Hard Disk 1 or 2 and press + or – until you see User Def 1 or User Def 2. 2. Press + to move the cursor to the Cy1 field. 3. Type the appropriate cylinder value for your hard disk.
If you installed an optional video card, follow the guidelines below to select the correct adapter type. Video display type options * For these options, you must change jumpers J1 and J2 on the system board to the OFF position. See Chapter 3 for information on setting jumpers. Setting Keyboard Options Two options in SETUP allow you to control keyboard settings. The Keyboard option allows you to disable the built-in keyboard connector.
Setting the Processor Speed The CPU Speed option sets the processor speed to fast or slow. At fast speed, your processor operates at its highest speed. At the slow speed setting, the processor operates at 8 MHz to provide compatibility with older application programs. Leave it set to fast speed unless you know your application program requires the slow setting. Cyrix Cache Option The 486SLC2-50 microprocessor includes a 1KB internal cache. Leave this option set to Enabled.
You can also shadow 32KB or 64KB of memory that starts at the indicated addresses to RAM. If you enable these options, you cannot use the Relocate Memory feature between 640KB and 1024KB. Additional options Two additional chip set feature options allow you to slow down your system in case you need compatibility with slower option cards or diskette drives.
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.
Exiting SETUP When you leave SETUP, you can save your settings and reboot your system, or exit SETUP without saving your settings. You can also return all values to the factory defaults. To leave SETUP, press Esc from any SETUP screen.
You may also want to install the optional extended video drivers and utilities. (If your computer was configured for you, these drivers are already installed.) For more information on installing video drivers and utilities, see the README.TXT files included on your Drivers diskettes.
Chapter 2 Using Your Computer This chapter briefly describes the following operations: Working comfortably Inserting and removing diskettes Stopping a command or program Resetting the computer 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.
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.
Note The 3.5-inch drive installed in your computer is drive A. If you install another diskette drive, it is drive B. You can change the drive assignments through SETUP. 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. Slide the diskette into the drive and then turn down the latch to secure it. When you want to remove the diskette, make sure the drive light is off; then press the release button or turn the latch.
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. 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.
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. 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.
To select fast speed, hold down the Ctrl and Alt keys and press + on the numeric keypad. 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 SETUP. The speed setting remains in effect until you reset your computer or turn it off.
Chapter 3 Installing and Removing Options You can enhance the performance of your computer by adding optional equipment such as memory modules, option cards, video memory, or a math coprocessor. This chapter first describes how to remove your computer’s cover to install options and how to replace the cover when you are finished.
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 4). Follow these steps to remove the cover: 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 cable. 3.
6. Grasping the sides of the cover, lift it up at an angle and pull it off, as shown below: 7. Set the cover aside. 8. 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. If you are not properly grounded, you could generate an electric shock that could damage a component when you touch it.
Replacing the Cover When you are ready to replace the computer’s cover, follow these steps 1. Make sure all the internal components are installed properly. 2. Check all cable connections, especially those that might have been loosened during your work. 3. Make sure all cables are out of the way so they do not catch on the cover. 4. Insert the lip at the front of the cover between the front bezel and the chassis of the computer and guide it straight down. (See the illustration on page 3-3.) 5.
Locating the Internal Components As you follow the instructions in this chapter, refer to the following illustration to locate the major components inside your computer.
Changing the Jumper Settings The jumpers on the main system board control certain functions and are preset at the factory to default positions; however, you can use the information in the following tables to change their settings, if necessary.
Jumper settings (continued) * Factory setting ** MS-DOS automatically reassigns parallel and serial ports. Check your MS-DOS manual for more information. Built-in VGA jumper settings * Factory setting Note To use an external display adapter in an expansion slot, you must disable the built-in VGA adapter. The jumpers listed in the preceding tables are the only jumpers you may need to change. Other jumpers on the system board are for service purposes only.
3. A jumper’s setting is determined by where the jumper is placed on the pins. Use the following table to identify the pin settings for 2-pin, 3-pin, and 4-pin jumpers. To locate pin 1, look at the system board under the jumper; a triangle is traced on the board at pin 1. To move a jumper from one position to the other, use needle-nose pliers or tweezers to pull it off its pins and gently move it to the desired position.
Installing Memory Modules Your computer comes with 4MB of memory on memory modules-also called SIMMs (single inline memory modules). By installing additional SIMMs, you can increase the amount of memory in your computer up to 16MB. There are four SIMM sockets on the main system board, and each can contain one SIMM. You can use 1MB and 4MB SIMMs. The following table shows the possible SIMM configurations; do not install memory in any other configuration.
Inserting SIMMs Follow these steps to install SIMMs: 1. Refer to the illustration on page 3-5 to locate the SIMM sockets. 2. Remove any option cards that may be blocking your access to the SIMM sockets. (See page 3-16 for instructions.) 3. Turn the computer around so the back panel is facing you. 4. Position the first SIMM at an angle over the first empty socket in the bank you are filling, as shown below. The components on the SIMM should face the inside of the computer.
5. Push the SIMM into the socket until it is seated firmly in the slot. Then tilt it upright, as shown above, guiding the hole at each end of the SIMM over the retaining post at each end of the SIMM socket. If it does not go in smoothly, do not force it; pull it all the way out and try again. 6. Repeat steps 4 and 5 for each additional SIMM. 7. Replace any option cards you removed. (See page 3-13 for instructions.
2. Use your fingers or a small screwdriver to carefully pull away the tabs that secure the SIMM at each end, as shown below. As you pull away the tabs, the SIMM falls to the side. Remove it from the socket. 3. If necessary, follow the same procedure to remove other SIMMs. 4. Replace any option cards you removed, as described below.
Installing an Option Card This section explains how to install option cards in your computer. Your computer has five 16-bit, ISA slots; three full length and two half-length.

If you are installing a 3.5-inch diskette drive with a header connector, see page 4-13 for instructions on connecting the cable. 3. Locate one of the power supply cables that lead from the power supply. (They have multi-colored wires and a plastic connector on the end.) 4. Align the notched corners of the power supply cable connector with the notched corners of the drive’s power supply connector (such as the one shown below). Make sure the holes fit over all the pins and then push in the connector.
Caution If you do not align the cable connectors correctly, you could severely damage your drive when you push them in. 5. If you installed a hard disk drive in one of the external bays, replace the faceplate. Insert one side of the plate, then gently press on the other side until it snaps into place. If you installed a diskette drive in the bay, it is drive B; the drive installed in the mounting bracket is A. You can change the drive assignments through SETUP.
3. Remove the two screws securing the drive on each side. 4. Reach behind the drive and gently push it to the front of the bay; then pull it out of the slot. 5. Once you have removed the drive, replace the faceplate by inserting one side of the plate, then gently pressing on the other side until it snaps into place. 6. Replace the diskette drive and mounting bracket and reconnect the cables. See page 4-8 for instructions.
Chapter 5 Troubleshooting If you have any problems as you setup 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. Serial number: Look on the label on the bottom of the computer to find the serial number. System BIOS version Restart your system, You’ll see the system BIOS version number displayed on the screen when your system performs power-on diagnostics. System configuration Start SETUP and select the System Summary option to see your system’s configuration.
The Computer Will Not Start The power light is on, but the computer does not start. Place a bootable diskette in drive A 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.
The Computer Does Not Respond The computer locks up. Wait a few moments; if your computer does not respond after a reasonable length of time, press Ctrl Alt Del. If that doesn’t work, press the RESET button. You may have installed memory using SIMMs that work at the wrong speed. You can try using the SETUP program to insert a wait state (see Chapter 1) or you can install the correct SIMMs (see Chapter 3). Your system may have overheated because its physical environment is too warm.
Nothing happens when you type on the keyboard. The Lockout Timer may be set in SETUP. This option inactivates the keyboard for a specified period of time after the system returns to an active mode from a low-power standby mode. This delay gives Energy Star compliant monitors the time they need to return to an active mode. Wait a few seconds and try again. See “The Computer Does Not Respond,” above. The cursor keys on the numeric keypad do not work properly.
Monitor Problems There is no display on the screen. Check that the monitor’s power switch is on and that its power light is lit. Also, the computer may be in low-power standby mode. When you press a mouse button or a key on the keyboard, see if the monitor displays an image. The power light is on, but you still do not see anything on the screen. Press a mouse button or a key on the keyboard to see if the computer is in low-power standby mode. Also, check the brightness and contrast controls.
Turn off the monitor’s power, wait five seconds, and turn it back on. If the light still does not come on, check the electrical outlet for power. Turn off your monitor and unplug it from the outlet. Then plug a lamp into the wall outlet and turn it on. If the light turns on, your monitor may be faulty. 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.
Something is wrong with the data in the files. If you are using MS-DOS, use CHKDSK to repair the files. You may also be able to use special utilities or diagnostics to solve this problem. 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.
You see a hard disk drive error when you start your system. Run SETUP and check that your system’s auto-sensing feature is detecting the correct drive type. If auto-sensing is embled and SETUP displays information that does not match your drive, you may need to define your own drive type. See chapter 1. Make sure the jumpers on the system board are set correctly. Jumpers J14 and J16 enable or disable the IDE hard disk drive controller. See Chapter 3 for jumper information.
You have been using your hard disk drive successfully for some time but notice a reduction in performance. The data on the disk may have become fragmented. Backup all your data and use a disk compaction utility to reorganize the files on your disk. If you cannot access data on your hard disk or you are seeing read/write errors, the disk may have a physical problem. Contact your Authorized EPSON Servicer or the EPSON Connection. Software Problems The application program does not start.
Your application has locked the computer, making it unresponsive to keyboard commands. Reset the computer and try again. If resetting the computer does not help, turn it off, wait 20 seconds, then turn it on again. ® ® ® Some software, like OS/2, UNIX, or NetWare, needs a minimum of 8MB to 16MB of RAM to work correctly. Check your software documentation for the minimum memory requirements. If necessary, add memory modules using the instructions in Chapter 3.
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. Run the SETUP program to update your computer’s configuration after you install the card. Also, perform setup procedures for any software you are using with the option card. See the documentation that came with the option card to set any necessary DIP switches or jumpers on 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 drive controllers, the video controller, or the I/O port controllers when you start your system. The indicated controller on your system board may be faulty.
Internal Battery Problems The screen displays an error message prompting you to run SETUP when you start your system, or your system displays as incorrect time and date. If your system has not been used for an extended period of time, your internal NiCad backup battery may be discharged. First, run SETUP to enter the correct time and date. (You may also need to re-enter your computer’s configuration information.) See Chapter 1 for instructions.
