It includes the following information: 0 Unpacking your computer 0 Setting the voltage selector switch 0 Connecting system components 0 Turning the computer on and off 0 Running the SETUP program 0 Post-SETUP procedures. Unpacking Your Computer When you unpack your system, make sure you have the items shown below.
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.
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.
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. / c \power inlet 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.
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.
Then turn on the computer by pressing the power button located on the right side of the front panel, as shown below. speed light ,,a p o w e r l i g h t “-rd - - disk dticesslight I I hard diskor reset diskette drive button bays I 1 -&.I.~ -qFY+ IIIIIIIIIIIIIIIIIIIIIIII T q diskette drive The power indicator lights up. After a few seconds, the computer performs its power-on diagnostics. This is a series of everything is working correctly.
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.
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 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 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.
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.
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.
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.
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 to enter SETUP that you see during power-on diagnostics.
The System Security and Anti-Virus Options 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. Entering or changing a password 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.
4. Press the spacebar. The Supervisor Password is now set to Enabled. IS option To set a User password, select the Set User Password option and follow the steps above. Deleting passwords To delete your passwords, follow these steps: 1. Set the Password on boot option to Disabled. 2. Delete the User password by pressing Enter for both the password field and the confirmation field. Don’t type any characters in these fields. 3. Then delete the Supervisor password the same way.
If you select Supervisor for this option, you can access the diskette drives only if you enter the Supervisor password when you start your system. Someone who starts the system with a she tries to access the diskette drive. If you select User for the Diskette Access option, you can access the diskette Note To use passwords for diskette drive access, you must enable the Password on boot option.
Using the Green PC Features The Green PC options allow you to define how the energy-saving features of this Energy Star compliant system will work for you. The options on the Green PC Features screen allow you to disable the energy-saving feature or set time-out periods to put the system and hard disk drive in a low-energy standby mode. The Inactivity Timer 1 option sets the time-out period for video signals to your monitor.
The System Summary Option When you select the System Summary option from the Main Menu, the SETUP program displays a summary of the configuration settings for your system. This is the same screen you see during system startup. You can choose not to have the system display this screen so system startup is faster. See page 1-14 for information on disabling this option Exiting SETUP When you leave SETUP, you can save your settings, or exit SETUP without saving your settings.
Post-SETUP Procedures After you run SETUP for the first time, you may need to install the operating system if your computer is not preconfigured. 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.
Chapter 2 Using Your Computer This chapter briefly describes the following operations: 0 Working comfortably 0 Stopping a command or program 0 Resetting the computer 0 Using energy wisely 0 Using the Green PC features 0 Changing the processor speed Working Comfortably This section provides some tips for creating a comfortable work environment. 0 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.
If you use a copy stand, keep it at the same eye level as your screen. This reduces eye and neck strain. Also, rest your eyes occasionally by closing them or focusing on a fixed spot in the distance. 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.
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. 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 Energy Wisely By purchasing this low-power, Energy Star compliant computer, you join a growing number of users concerned about conserving energy. Here are a few additional tips you can use to be even more energy-wise: 0 If your printer and monitor aren’t Energy Star compliant, turn them off when you’re not using them. 0 Use your software’s print preview option (if available) before you print something. You’ll be able to catch formatting errors before you commit them to paper.
Note Some hard disk drives do not support a low-power standby mode. Also, the delay caused by the hard disk drive returning to active mode may cause errors in some applications. If you have problems, you may want to disable the standby mode for the hard disk drive. Changing the Processor Speed Your computer’s processor can operate at two speeds: fast or slow (8 MHz).
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.

Adding Video Memory Your computer comes with 512KB or 1MB of video memory. If you have 512KB, you can increase your video memory to 1MB by installing four video DRAM DIP (Dual Inline Package) chips. The chips must be 20-pin, 256KB chips that operate at a 70ns access speed. For the memory to work properly, you must install one chip in each empty video RAM socket on the system board.
Locate the video memory sockets on the main system board, shown on page 3-5. If there is an option card in your way, remove it. See page 3-17 for instructions. Caution To avoid generating static electricity and damaging the memory chips, ground yourself by touching the metal surface on the inside of the computer’s back panel. Then remain as stationary as possible while you install them. Remove the memory chips from their package and inspect each one.
Gently press the chip halfway into the socket (to make sure it is correctly aligned). If the chip does not go in smoothly, remove it and try again. When the chip is properly positioned, push down firmly on both ends to make sure it is well-seated. Repeat steps 4 through 6 for each of the remaining chips. Replace any option cards you removed. See page 3-14 for instructions. Installing External Cache You can install 64KB, 128KB, or 256KB of external cache on your system.
For the cache memory to work properly, you must install chips in the following configuration (each bank contains four cache memory sockets): Cache memory configurations Bank 0 U23 - U26 Bank 1 U30 - U33 Tag SRAM U34 Total cache 8K x 8 8K x 8 8K x 8 64KB 32K x 8 - 8K x 8 128KB 32K x 8 32K x 8 32K x 8 256KB Note that your cache memory sockets may not look exactly like the ones illustrated here.
3. Remove the cache chips from their package and inspect them. The pins should point inward at slightly less than a 90° angle. If any of the pins are bent or crooked, straighten them gently with your fingers or with small tweezers to align them with the other pins. Be careful when you do this; the pins are fragile and can break off easily. 4. Position one of the cache chips over the first below, aligning the pins on the chip with the socket.
9. Replace any option cards you removed. See page 3-14. 10. Run SETUP to enable the External Cache option and check that the System shadow and Video shadow options are enabled. You select these options from the Memory Cache and Memory Shadow options on the Advanced System Setup menu. (See Chapter 1.) Upgrading the Microprocessor You can upgrade your computer by replacing the microprocessor with a faster one.

Removing a Hard Disk Drive From the Mounting Bracket Follow these steps if you need to remove the hard disk drive from the bracket: Disconnect the cables from any drives installed in the mounting bracket. Grasp the connectors and pull them straight out so you do not bend the pins; do not pull on the cables. Remove the screws securing the bracket to the drive bay and brace. Slide the bracket away from the front of the computer and lift it out. P 4-14 4.
Installing a Drive in an External Drive Bay Your system comes with two externally accessible drive bays. You can use these bays to install any of the following: diskette drive, hard disk drive, CD-ROM drive, tape drive, or optical drive. If you are installing a diskette drive or a tape drive with a standard 5.25-inch diskette drive connector, you can connect it using the diskette drive cable that came with your system.
Attaching Mounting Fames to the Drive If you are installing a 3½-inch wide drive, you need to attach mounting frames to the drive. If you are installing a drive that already has mounting frames on it, see if it also has a plastic guiderail and metal grounding plate attached to it. If so, follow step 1 on page 4-5 to remove the guiderail and grounding plate. Then go to “Installing the Drive” on page 4-17. Follow these steps to attach mounting frames to a drive: 1.
Installing the Drive Follow these steps to install a drive in the upper or lower external drive bay: 1. Remove the faceplate from the drive bay by pushing it out from the inside of the computer. Keep the faceplate in a safe place in case you remove a drive later (or you are installing a hard disk drive).
2. 3. 4-18 Slide the drive through the slot 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 or mounting frames. Then secure both sides of the drive to the bay using the retaining screws.
Connecting the Drive and Power Cables If you are installing a diskette or tape drive, follow all the steps below. If you are installing a hard disk drive, follow the instructions on pages 4-9 through 4-12. Then go to step 5 below. Note If you have one hard disk drive installed in the bracket below the diskette drive and will install and a second hard disk drive in the external bay, you need to purchase a new hard disk drive cable that can reach both drives.
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 connector (such as the one shown below). Make sure the holes lit over all the pins and then push in the connector.
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. After you have completed installation of the drive in the external bay, you must replace the drive mounting bracket and reconnect the cables. See page 4-8 for instructions. Removing a Drive from an External Bay To remove a drive from an external bay, follow these steps: 1. Remove the drive mounting bracket.
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 drive mounting bracket and reconnect the cables. See page 4-8 for instructions.
Chapter 5 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 : Serial number: Look on the back panel 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 during power-on diagnostics. System configuration: Start SETUP and select the System Summary option to see your system‘s configuration. MS-DOS version: VER and press Enter to see the MS-DOS version number.
The Computer Will Not Start The power light is on, but the computer does not start. Make sure the boot options in SETUP are set to access drive A. Then 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.
You may have installed a SIMM incorrectly. If the system doesn’t detect memory, it won’t start. Check that your SIMM(s) are securely installed in their sockets. If you replaced the microprocessor, make sure the new processor chip is installed correctly. Also make sure the jumpers are set correctly and pin 1 on the chip is connected with pin 1 on the system board. See Chapter 3. The Computer Does Not Respond The computer locks up.
Keyboard Problems The screen displaysa keyboard error message when you turn on or reset the computer. Make sure the keyboard is securely connected to the keyboard port and not the mouse port. Although these ports look alike, they cannot be used interchangeably. 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.
Monitor Problems There is no display on the screen. Check that the monitor’s power switch is on and that its power light is on. 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.
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. Also, check to see that you have inserted the right type of diskette in the drive.
Something is wrong with the data in the files If you are using MS-DOS, run 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 is auto-sensing the correct drive type. If auto-sensing is enabled 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 JB and JE 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. Back up 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. Password Problems You have forgotten your password.
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.
Printer Problems The printer or scanner does not work at all. Check that the printer or scanner has power and is properly connected to the computer. Also make sure your printer has paper in it. If you are using more than one serial port and one is for your printer, check the primary and secondary port settings (COM1 and COM2) in your application program.
Your system may need to operate at the slower processor speed to access the device. Try reducing the processor speed (see Chapter 2). Make sure you install option cards that meet the system’s power requirements. See Appendix A. Make sure the option card is not touching any other card. Also make sure the card isn’t touching the CPU or any fan or heat sink you have attached to the CPU. If a fan or heat sink is attached to the CPU, don’t install an option card in the lowest 16-bit option slot.
Controller Problems You see a controller error for the drive controllers 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.
