Introduction Your new EPSON® computer is a fast, high-performance system offering flexibility and expandability in a compact design.
Your system has a local bus interface for the video. This bus can transfer data at the full speed of your processor rather than at the standard 8.33 MHz ISA bus speed, so your system can transmit video data far more quickly. This local bus, together with the standard on-board video memory, provides fast video response in a range of resolutions and colors. (See Appendix A for a list of supported resolutions.
SVGA Utilities Your computer comes with special SVGA drivers and utilities for use with the integrated local bus SVGA interface. Use these utilities to take advantage of extended VGA features such as high resolutions and 132-column text mode when you run popular application programs. Instructions for installing and using these drivers are in a README file called VGADRV.TXT on the Utilities 1 diskette.
Video Memory Your system comes with either 512KB 1MB video memory on the system board. If your system contains 512KB of video memory, you can add additional memory chips to your system board to increase the video memory to 1MB and support higher video resolutions, multimedia graphics adapter cards, or applications that require higher memory. Cache Memory Your system may have external cache memory already installed for you.
Option Cards With four available 16-bit ISA slots, your computer can support a variety of option cards such as fax modem, network, and multimedia cards. Your system may come with these options installed for you. How to Use This Manual You don’t have to read everything in this book to use your computer; see the following chapter summaries to find the sections you need.

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 Do not connect or disconnect any peripheral device cables (including the mouse or keyboard) or power cables unless the computer power is off. 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. power (SPEED) indicator hard drive access indicator diskette drive power button 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 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 : \). If your system is configured to automatically load a program (such as Windows or a word processing program), you see the first menu or screen display of that program. Now you need to run SETUP to make sure your computer is configured properly.
Chapter 2 Running the SETUT Program The first time you use your computer, you may need to run the SETUP program. If your system was configured for you, you may want to check the settings or adjust the date and time. If you change your configuration, you may need to run it again.
The SETUP program and the factory default options for your computer are stored in the computer’s ROM BIOS (read-only memory, basic input/ output system). The configuration information you enter is stored in an 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.
When you press Del, you see a SETUP menu containing these options: 1. 2. 3. 4. 5. 6. 7. Start operating system Run SETUP Set Password options Display system board help Load default SETUP values SAVE settings and exit Exit without saving settings Type the number of the menu option you want to select, or use ‘/‘or & to move the cursor over the option you want to select and press Enter. As you highlight each menu selection, you’ll see a description of the option at the bottom of the screen.
Selecting Options A solid cursor bar highlights the selected parameter. Press t, ‘/‘, +, & to move the cursor to the parameter you want to change. Then press Page Up or Page Down to display the available options. As you move the cursor to each parameter, you see a description of the available options for that parameter at the bottom of the screen. The following sections describe how to choose the correct SETUP parameters for your system.
Setting the Diskette Drive[s) Your system probably came with a 3.5-inch diskette drive or a 5.25/3.5-inch combination drive installed. You may also have another drive of a different size or capacity. Check the settings for both drives and correct them if necessary. (If you have only one diskette drive or if you install a drive that isn’t attached to the diskette drive connector on the system board, select Not Installed for drive B.
Defining Your Own Drive Type If the parameters for your hard disk drive (listed in its documentation) do not match any of the types listed in the hard disk drive table in Appendix A, you can define your own type. Follow these steps: 1. Move the cursor to the hard drive you are defining. 2. Press Page Up until you see type 47. 3. Type the values in each field that are appropriate for your hard disk drive; press + to move the cursor to the next field.
Video display type options If you have two display adapters of different types, select the setting for the one you want to be your primary display adapter. If you install one type of display adapter card and then change the adapter (from VGA to CGA or vice-versa), you also may need to change the setting of DIP switch 5. If you have two types of cards, set the jumper and DIP switch to match the adapter controlling your primary display.
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. You can also change the speed temporarily by entering a keyboard command. See “Changing the Processor Speed” in Chapter 3 for more information. Setting the Booting Sequence The booting sequence determines the order in which the computer checks the drives when it looks for the operating system.
Using Virus Protection The SETUP program also provides a virus protection feature that prevents viruses writing to the boot sector on your hard disk drive. To use this feature, enable the Virus protection option. Then when any program tries to write to the boot sector of your hard disk drive, you see a warning message.
Setting the Shadow Options Your computer can access RAM (random access memory) faster than ROM (read only memory). The shadow feature on your system automatically copies the contents of both the system BIOS and the video BIOS into RAM so your system can perform certain operations faster. 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.
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 Pass word Options SETUP lets you enter a new password or disable an existing password to control who can access your system. An additional 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 Page Down 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 change or 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 : DIP switch settings Jumper settings Identification of connectors Possible SIMM configurations External cache configurations Hard disk drive types System key combinations. To use this help board help, from scroll through the selected option in function, select option 4, Display system the main menu. Use the arrow keys to 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 E SC to return to the main SETUP menu 2. Select option 6, SAVE settings and press Enter. You see this message: exit, and Write to CMOS RAM and exit (Y/N)? 3. Press Y and Enter. The system reboots 4. If you have just run SETUP for the first time, see “Post-SETU P 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: 0 Working comfortably 0 Using energy wisely 0 Using disks and disk drives 0 Stopping a command or program 0 Resetting the computer 0 Using the password and hot key features 0 Changing the processor speed. Working Comfortably Follow these guidelines to create a comfortable work environment. Use good posture.
0 Keep your copy stand 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. 0 Type gently. 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. 0 Use good lighting that isn’t too bright. Keep bright lights out of your field of vision when you look at the screen.
Using Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use your stored data. Using Diskettes As you use your diskette drives, keep these points in mind: 0 Drives can usually read from and write to diskettes that have the same capacity or a lower one, but not to diskettes that have a higher capacity. 0 If you want to form at a lower capacity diskette in a drive with a higher capacity, make sure you include the correct parameter in your format command.
Inserting and Removing Diskettes To insert a diskette into the label facing up and shown in the following drive until it clicks into a 3.5-inch drive, hold the diskette with the shutter leading into the drive, as illustration. Slide the diskette into the place. release button 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 the diskette is completely in the drive, turn down the latch to secure the diskette.
Using Hard Disk Drives Using a hard disk is similar to using diskettes. The hard disk drive, however, can contain many times more information than a diskette. Your system can also perform read and write operations to the hard disk more quickly than to a diskette. As you use your hard disk drive, keep these points in mind: Hard disks can contain hundreds of files of information. Use the file management techniques described in your operating system manual.
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 current settings or its memory without turning it off. You can do this by resetting the computer.
Using a Pass word If you set a system access password in SETUP, 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: Type your password and press Enter. 3. After you type the password correctly and press Enter, 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 Enter. Changing or Deleting a Password To change or delete your password, you must run the SETUP program and follow the instructions in Chapter 2 for entering a password. If you do not know your password, see “Password Problems” in Chapter 6.
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. If you use a copy-protected program, you can change the speed to slow to access the diskette and return it to fast speed when you are finished.
Chapter- 4 Installing and Removing Options You can enhance the performance of your computer by adding optional equipment such as memory modules, option cards, processor upgrades, or video memory. This chapter first describes how to remove the cover on your computer to install options and how to replace the cover when you are finished.
Use the illustrations in this chapter as guidelines for installing options. The sockets on your system may look different than the ones illustrated here. Make sure you align your options as described in the text. Once you have installed your options, see “Post-installation Procedures” on page 4-30. Note Your system also supports 32KB, 64KB, 128KB, or 256KB of extended cache memory. (Upgrade kits for 128KB and 256KB of external cache are available from EPSON.
Locating the Internal 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).

Facing the front of the computer, position the cover so the lip on its bottom edge slides under the guiderails along both sides of the computer case.
Changing the Jumper and DIP Switch Settings The main system board in your computer has a number of jumpers and DIP (Dual In line Package) switches. These devices control the operation of your system and provide configuration information to your CMOS ROM. Jumpers and DIP switches are preset at the factory to match your system’s configuration, but you may need to change them when you install certain options or want to change some functions.
Setting the Jumpers If you need to change any jumper settings, follow these steps: 4-8 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 4-18.
3. A jumper’s setting is determined by where the jumper is placed on the pins. For three-pin jumpers, the jumper connects the first pin and the middle pin (position A) or the last pin and the middle pin (position B), as shown below. (Look for A and B printed on the system board to help you identify each position.) In the off position, a three-pin jumper sits on only one of the end pins.
Setting the DIP Switches If you need to change any of the DIP switch settings, follow these steps: 4-10 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.
Memory Modules [SlMMs) Your computer comes with 4MB of memory soldered 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 1MB, 4MB, or 16MB. The following table shows the possible SIMM configurations. You can install SIMMs in either SIMM socket.
Inserting SlMMs Follow these steps to install SIMMs: 4-12 1. Refer to the illustration on page 4-3 to locate the SIMM sockets near the front of the computer. 2. Remove any option cards that may be blocking your access to the SIMM sockets. See page 4-18 for instructions. 3. Position the SIMM over the socket at an angle, as shown below. The components on the SIMM should face the outside of the computer. (A plastic tab on the socket prevents you from putting the SIMM in backward.
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. If it does not go in smoothly, do not force it; pull it all the way out and try again. 5. Repeat steps 3 and 4 for the second SIMM, if necessary. 6. Replace any option cards you removed. See page 4-15 for instructions. 7.
Removing SlMMs If you need to remove SIMMs from your computer (to install different ones, for example), follow the steps below. 4-14 1. Remove any option cards that may be blocking your access to the SIMM sockets. See page 4-18 for instructions. 2. Use your fingers or a small screwdriver to carefully release the metal tabs that secure the SIMM at each end. As you release the tabs, the SIMM falls to the side. Remove it from the socket. 3.
Installing an Option Card This section explains how to install an option card in your computer. Your computer has four option slots to accommodate up to four S-bit or 16-bit option cards. Follow these guidelines when installing option cards: 0 Usually it does not matter which slot an option card occupies as long as the card fits in the slot. For example, you can place some S-bit cards in a 16-bit slot.
Follow these steps to install an option card: 1. If you are installing a card in the option slot for the first time, you need to remove the metal cover for that slot on the inside back panel. Remove the retaining screw securing the option slot cover to the computer. (Keep the screw to secure the option card to the computer.) option slot cover 4-16 2. Slide out the slot cover and set it aside. (Store the slot cover in a safe place in case you remove the option card later.) 3.
4. Hold the card along the top corners and guide it into the connector, as shown below. Once the connectors reach the slot, push the card in firmly (but carefully) to insert it fully. You should feel the card fit into place. If it does not go in smoothly, do not force it; pull the card all the way out and try again. 5. Secure the end of the card to the computer with the retaining screw.
Removing an Option Card You may computer change a remove a need to remove an option card installed in your to access components on the main system board-to jumper setting, for example. You may also want to card if you no longer need it. Follow these steps: 1. Remove the retaining screw securing the option card to the computer. Then pull the card straight out of the slot. 2.

See page 4-15 for instructions.
3. Remove the memory chip from its package. 4. Position the chip over the socket, as shown below. Make sure the notch in the chip aligns with the arrow that identifies pin 1 on the socket. (A notch in the outline for the socket drawn on the system board also identifies pin 1.) 5. Gently press the chip into the socket. If it does not go in smoothly, remove it and try again. 6. Replace any option cards you removed. See page 4-15 for instructions. 7.
Using the S VGA Feature Connector Your computer includes an alternate SVGA interface (feature connector) on the main system board. If you install a high-resolution graphics or a full-motion, multimedia adapter card in one of the computer’s option slots, this connector allows you to access the standard SVGA signals provided by your system circuitry.
2. Attach one end of the feature cable to the alternate SVGA interface on the main system board near the back panel, as shown below. Align the cable so the red wire along one edge is closest to pin 1 on the connector. (Look for a 1 printed on the system board to identify pin 1 of the connector.) 3. Connect the other end of the cable to the appropriate interface on the adapter card. (Check your graphics card manual for instructions.
Installing a New Processor Chip You can enhance your system’s performance by installing a faster, more powerful processor. Alternatively, for an SX system, you can install a 487SX microprocessor with a built-in math coprocessor. The following table lists the processors you can use in your system : Microprocessor upgrades SX2, DX/ 33, DX/ 50, DX2/50, DX2/66, DX4, and Pentium OverDrive processor upgrades require a heat sink. DX4 processors also require an adapter board with the appropriate voltage regulator.
Replacing the Processor Chip Follow these steps to replace the current processor with a new one: 1. Use the illustration on page 4-3 to locate the processor socket on the system board. The-processor is inserted in a ZIF (Zero Insertion Force) socket. Caution Make sure you ground yourself by touching the metal surface on the inside of the computer’s back panel before you touch the processor chip. Then remain as stationary as possible while you install it. Do not touch the pins on the processor chip.
Note The 486SX processor may be soldered onto an adapter board that is seated in the ZIF socket. Lifting the ZIF handle releases the adapter board from the socket. Gently pull the processor chip straight up and set it aside. Remove the replacement chip from its package and inspect the pins. If they are bent, do not install the processor chip. Contact your vendor for a new processor. Position the processor chip over the socket, as shown below.
7. Secure the processor by pulling the ZIF handle back to the closed position. 8. Check the tables on page 4-7 to see if you need to change any jumper or DIP switch settings for the processor you are installing. 9. Run SETUP as described in Chapter 2 to update your computer’s configuration with the new processor. Replacing the Battery Your computer comes with a 3.6 volt lithium battery that provides power for the real-time clock and the CMOS RAM.

Connecting the Cables To connect the hard disk drive to the computer, you need to connect two cables: the hard disk drive ribbon cable and a power supply cable. Follow the steps below: 1. If you are installing your computer’s first hard disk drive, you need to connect the hard disk drive ribbon cable to the system board now. Follow the instructions on page 5-29 and then return here. 2.
4. Make sure the holes in the cable connector fit over all the pins in the hard disk drive connector; then push in the connector. Caution If you do not correctly align the holes with the pins, you could severely damage your hard disk drive when you push in the cable connector.
5. Locate one of the power supply cables that lead from the power supply (behind the horizontal drive bays). The power supply cables may be secured in a plastic band on the side of the power supply. If so, unfasten the band to access the cables; you can use any free cable. (If your drive requires a small power supply cable connector, use the small connector labeled PD.) 6.
Removing a Hard Disk From the Vertical Bay Follow these steps to remove a hard disk drive from the vertical drive bay: 1. 5-12 Disconnect the hard disk drive ribbon cable and power supply cable from the back of the drive, as shown below. Grasp the cable connectors and pull them straight out from the connectors on the hard disk drive so you do not bend the pins; do not pull on the cables.
2. Remove the retaining screw securing the hard disk drive and mounting plate to the horizontal drive bays. Then slide the hard disk drive and mounting plate in the direction of the arrow, shown in the following illustration, and lift them out of the computer. 3. Remove the four screws securing the mounting plate to the hard disk drive. You can store the mounting plate and its screw or replace it in the computer and secure it with the screw. 4.
If you removed one hard disk drive and are leaving another one in the computer, you need to set the jumpers on the remaining drive to indicate that you now have only one hard disk drive. For the correct settings, see the documentation that came with the drive. Installing a Drive in a Horizontal Bay This section describes how to install a drive in a horizontal bay.
Depending on the type of drive you are installing, you may need to attach mounting frames to it before you install it in a horizontal bay. Follow these guidelines: 0 If you are installing a drive with a 5.25-inch form factor, skip to “Installing the Drive” on page 5-17. 0 If you install a drive that has a 3.5-inch form factor, it must have mounting frames to fit properly in the horizontal bay. Follow the steps in the next section.

Disconnect the drive ribbon cable and power supply cable from the back of the drive.
3. If you are leaving the drive bay empty, replace the metal drive bay cover and two retaining screws, as shown below. 4. If you are replacing the drive you removed with another drive, remove the guiderails and screws from the drive and use them to install the other drive as described in “Installing a Drive in a Horizontal Bay” on page 5-14. 5. Wrap the drive in its original packing materials and store it in a safe place. 6.
If you removed one hard disk drive and are leaving another one in the computer, you need to set the jumpers on the remaining drive to indicate that you now have only one hard disk drive. See the documentation that came with the drive for the correct jumper settings. 7. 5-28 If you removed a diskette drive from the lower bay and you are leaving the bay empty or installing a hard disk drive in it, you need to replace the front panel faceplate on the computer’s cover.
Connecting the Hard Disk Drive Ribbon Cable to the System Board Follow these steps to connect the hard disk drive ribbon cable to the system board: 1. Locate the hard disk drive connector on the system board. It is next to the diskette drive connector, between the option card connector board and the power supply. Note You may find it easier to plug in the cable connector if you first remove the option card connector board and diskette drive ribbon cable.
3. Select the connector on the end of the longest part of the cable (the main system board connector). Notice the small tab in the middle of the cable connector, as shown in the illustration above. Align the connector so that the tab aligns with the notch, as shown below. (The option card connector board and diskette drive ribbon cable are removed from the illustration for clarity.) notch 4.
5. If you removed the option card connector board and diskette drive ribbon cable, replace them now. To connect the diskette drive ribbon cable, align the tab on the cable connector with the notch in the system board connector. Make sure the holes in the cable connector fit over all the pins in the system board connector and push in the cable connector. If you removed the option card connector board to connect the cable, replace it as described on page 4-20.
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 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: Use SETUP to see your system’s configuration. MS-DOS version: At the MS-DOS prompt, type VER and press Enter to see the MS-DOS version number.
The Computer Will Not Start 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 power cord is securely connected but the computer still does not start. Check the electrical outlet for power. Turn off your computer and unplug the power cord. Plug a lamp into the outlet and turn it on. You installed or removed system components, and now your computer does not start.
The power light is on, but the computer does not load the operating system. 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. If the system starts from the disk in drive A, you may have a problem with the hard disk drive. 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.
Your computer suddenly stops operating. Turn the computer off and leave it off for at least 30 seconds. This resets the power supply logic. Make sure the room temperature around the computer is less than 90°F (32°C) and nothing is blocking the power supply fan. Also make sure there is ample room around your system for air circulation. You may have overloaded the power supply. See your option card manual(s) for the power requirements for your option card(s).
Monitor- Problems The power switch is on but the power light is not 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. There is no display on the screen. Check that the monitor’s power switch is on and that its power light is on.
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. If reinserting the diskette does not solve the problem, insert the diskette in another diskette drive of the same type. If you can read the diskette in a different drive, your drive may be faulty. The diskette is the right type, but you still see an error.
The diskette drive is making loud or unusual noises. Contact the EPSON Connection or your Authorized EPSON Servicer. Hard Disk Drive Problems A newly installed hard disk drive is not working properly or ifs performance is not what you expect. Make sure you have installed the drive correctly and check all cable connections. Also, check the jumper settings on your drive. You see a hard disk drive error when you start your system.
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 before you partition it or install the operating system. Note that a physical format is different from software-based formatting commands, such as the MS-DOS FORMAT command.
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. See Chapter 3 for instructions.
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. You see a port error message for the port your printer is using. You may need to identify primary and secondary ports in SETUP.
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 processor or heat sink you have attached to the processor. An external device connected to the option card is not working correctly. Make sure you are using the proper cable to securely connect the device to the card.
Mouse Problems Your mouse isn't working properly or you see an auxiliary device error message. Make sure the mouse cable is securely connected to the MOUSE port and not the keyboard (K/B) port. Also make sure you installed the mouse driver correctly (if necessary). See the documentation that came with your mouse for instructions. (Windows automatically installs a mouse driver when you install the program .
Battery Problems You see a CMOS battery error when you start your system. Your system has a 3.6 volt, replaceable lithium battery that should last from three to five years. If you see either of the following errors, replace the battery. (See Chapter 4.) CMOS battery state low CMOS system option.
