Introduction Your Epson ® Equity TM I+ personal computer is a versatile, expandable, and economical system. Its flexibility lets you create your own system; first you choose from three models of the Equity I+ main unit, then you select the accessories you want to use with it to assemble the configuration that does the most for you. The Equity I+ main unit is available in three configurations: l One floppy disk drive l Two floppy disk drives l One floppy disk drive and one internal hard disk drive. You also choose which monitor you want to use. Optional cards and external devices further ex..
The Equity I+ comes with the MS”-DOS operating system and the GW”-BASIC programming language. If you have used MS-DOS before on another computer, you will find that it works the same on the Equity I+. Be sure to refer to your Equity MS-DOS manual, however, for descriptions of the special utility programs added by Epson. You may have purchased other software as well; you can use most soft- ware products designed for the IBM PC on your Equity I+. Refer to your software program documentation for information on using the software. Additionally, the Equity I+ supports multiple users and mult..
Chapter 1 Setting Up Your System Setting up your Epson Equity I+ personal computer is easy. Just follow the nine easy steps in this chapter. You should also refer to the “Quick Guide To Setting up Your Equity I+ ” reference card. 1 Unpacking As you remove the components from their cartons, be sure to inspect each piece. If anything is missing, looks damaged, or seems wrong, consult your Epson dealer. Be sure to keep your packing materials. They provide the best protection possible for your computer if you need to move or ship it later. When you unpack your Equity I+, you should find the..
Removing the disk drive protector sheet A cardboard sheet occupies the disk slot in the floppy disk drive. This sheet is inserted at the factory to protect the recording read/write heads. Be sure to remove it before you connect any cables. Press the button on the left side of the drive. When you release it the edge of the protector sheet pops out. Carefully pull out this sheet. Save the protector sheet and reinsert it whenever you move the com- puter, even if you are just moving it to another part of the room. If you are not going to use your computer for a week or more, when you go on vaca..
l No electromagnetic interference. Locate your system away from any electrical device that generates an electromagnetic field. Surprisingly, even your telephone can cause problems, especially if you keep diskettes right next to it. When you find the ideal location for your Equity I+, you can start to set up your system. 3 Arranging the Components First decide how you want to arrange your system components. The most common setup, shown in Figure 1-1, is to lay the main unit flat and set the video monitor on top of it with the keyboard directly in front (leaving enough space to insert diskett..
Before you connect the cables, take a look at the rear and front panels of the main unit. The rear panel Look at the rear panel to identify the Equity I+ input/output ports. Figure 1-2 shows where you connect the peripheral devices. WARNING: Do not connect the power cord until you have con- nected all peripheral devices. Always check to see that the power switch is off before you connect or disconnect any peripherals.

5 Connecting the Video Monitor To connect the video monitor, place it on top of or near the Equity I+ main unit. It is easiest to connect the monitor cable if the backs of the monitor and the main unit are facing you. Note: Your dealer probably installed a video card in your main unit to control your monitor. If not, you need to install it before you can connect your monitor. See Chapter 3 for installation instructions. The way you connect your monitor depends on the type you have. Refer to your monitor manual or follow these guidelines: 1. If necessary, connect the video monitor cable to y..

Connecting the cable to the main unit 3. Gently push the cable into the retaining clip, and close the cover. You can use the keyboard at different angles such as laying it flat on a desk or placing it on your lap. You can also tilt the keyboard by adjusting the legs on the bottom. Adjust the keyboard legs by turning the keyboard over, reaching under the lip and pulling each of the legs upward until t..
Figure 1-8. Adjusting the keyboard legs To lower the legs, gently squeeze the sides until they move out of the slot and push down on the leg until it clicks into place. To disconnect the keyboard, open the cover on the main unit and press down on the retaining clip to release the cable. Lift the tab on the connector, and pull it straight out from the main unit. 7 Connecting the Printer Your Equity I+ has both serial and parallel built-in interfaces. You can easily connect a printer or plotter that has either a serial or parallel interface. Just follow the instructions below. Parallel interf..
To connect your printer to a parallel interface: 1. Place the printer in a convenient location next to your system, as shown in Figure 1-9 for example. 2. 3. 4. Figure 1-9. Locating the printer Before connecting any cables, make sure the power switches on both the main unit and the monitor are switched off, If you are not sure which cable you need, consult your dealer. One end of the printer cable has a 25-pin male D-connector. (Refer to your printer manual to determine which end this is.) Connect this end to the socket marked PARALLEL on the back panel of the main unit. If the plug has ret..

Serial interface If you have a printer (or other peripheral, such as a modem) with a serial interface, connect it to the port marked SERIAL (RS-232C) at the back of the main unit. If the cable is a non-standard type, with a male D-connector at both ends, you need an adapter to connect it to the computer. To connect your serial device, follow the same steps above for connecting a parallel device. The RS-232C serial port needs to be configured properly in order for it to ..
8 Setting the DIP Switches The DIP switches on the Equity I+ are set to provide your system with information about itself. Each time you turn on your system, it checks the DIP switch settings to determine the keyboard type, coprocessor status, memory size, monitor type, number of floppy disk drives, and the typo of interfaces being used. The DIP switches are located underneath the cover on the front of your main unit, below the disk drives, as shown in Figure 1-11. Figure 1-11. Location of DIP switches Your Epson dealer should have set these switches for you. However, read this section to b..

Switch 1 (keyboard)-tells your computer what kind of keyboard is attached to your system. The factory setting is off for the standard (enhanced) key board which comes with your Equity I+. Switch 2 (coprocessor)-tells your computer whether or not an optional math coprocessor is installed. The factory setting is on to tell the system that this option has not been installed. Switches 3 and 4 (memory size)-indicate how much built-in memory is avail- able. These switches should never be changed unless you install a memory card and you want to use part of the optional memory instead of the built-..
DIP switch set 2 (parallel and serial port operations) The parallel and serial port functions controlled by DIP switch set 2 are listed in Table 1-3 and described below. Table 1-3. DIP switch set 2 Switches 1, 2, 3, and 4 tell the computer how to access the built-in parallel and serial ports. You do not need to change the factory settings unless you install an option card with an additional parallel or serial port. If you do install such an option card, read the following information carefully. Switches 2 and 2 (parallel port)-tell the computer how to access the built-in parallel port. The ..
Switches 3 and 4 (serial port)-tell the computer how to access the built-in serial port. The built-in serial port functions as either the primary or secondary serial port. However, if you install any option card with its own serial port you must set these two DIP switches so there is no conflict between the built- in serial port and the added card. Table 1-3 shows how to set the DIP switches. If you install an option card with a serial port preset as primary by the manufacturer, you must designate it as the primary port and designate the built-in port as the secondary port. If you install a..
9 Turning On the Computer After you set up your system, you’re ready to turn on the power and start using your Equity I+. But before you do turn it on, read the following safety rules. Safety rules 1. Never turn the computer on or off with a disk drive protector sheet in the disk drive. 2. 3. 4. 5. 6. 7. Do not attempt to dismantle any part of the computer. Only remove the top cover to install and remove option cards. If there is a hardware problem you cannot solve after reading Chapter 4 on troubleshooting, or if you want to install an optional 8087 math coprocessor, consult your Epson d..
You can turn on your computer with or without a system diskette in the top disk drive. For now, leave the drive empty. When you are ready to turn on the computer, press the power switch at the upper-right corner once. The power indicator on the front panel lights up and the cooling fan inside the main unit starts. After a few seconds, the computer begins to perform an internal test. If you cannot see the screen display clearly, use the controls on your monitor to adjust the brightness and contrast until characters on the screen are clear and bright. If the display is not stable, check your ..
If your system has a hard disk, you need to prepare it before you can run an operating system on it. Refer to “Using a hard disk drive” in Chapter 2 (and to your Diagnostics and MS-DOS manuals) for instructions on how to prepare a hard disk for use. If your hard disk has been properly prepared and set up to automatically boot MS-DOS, the message above does not appear. Instead, the operating system loads when you turn on the computer. The date and time prompts display and then the system prompt: c> This indicates that the hard disk has been assigned as drive C. 1-20..
Chapter 2 Using Your Equity I+ Once you have set up your Equity I+, you’re ready to take advantage of its versatility. This chapter describes the special keys on the keyboard, how to change your computer’s operating speed, and how to reset and turn off your computer. It also explains how to use and care for your disks and disk drives. Special Keys Certain keys serve special functions and are used in various ways by application programs. Some of the more important keys are shown in Figure 2-1. Table 2-1 describes each of these keys as well as others with special functions. Figure 2-1. Eq..
Table 2-1. Special key functions Key Purpose Tabk- -I Moves the cursor to the right in normal mode (and to the left in shift mode in some application programs). Caps Lock Changes the letter keys from lower- to uppercase; changes back to lowercase when pressed again. Shift Produces uppercase characters or symbols when used with the main character keys. Produces lowercase characters when Caps Lock is on. Ctrl Works with other keys to perform special (control) functions, such as editing operations in MS-DOS and GW-BASIC. Alt Works with other keys to enter alternate character codes not otherwis..
To change the speed, move the switch on the front panel as shown in Figure 2-2. To run the computer at 4.77MHz, move the switch to the left. To run it at 10 MHz, move the switch to the right. You can do this at any time without rebooting the system. Figure 2-2. Speed switch The power light on the front panel is red when the computer is running at 4.77MHz and green when it is running at 10MHz. Resetting the Computer You may occasionally need to reset the computer, either to load a differ- ent operating system, or because a program has failed and the computer does not respond to your keyboard..
There are three ways to reset; you should use them in this order: 1. If you are using MS-DOS, press Ctrl and Alt together with the Del key on the numeric keypad at the right of the keyboard. The screen goes blank for a moment, and any system disk in drive A reloads. If the problem is not corrected after trying this, try the second method. 2. Press the RESET button under the hinged flap beneath the disk drives. This method works even when the keyboard is not responding. If this fails to have any effect, try the third method. 3. Remove any diskettes from the disk drives. Turn off the monitor ..
How disks work The floppy disks (diskettes) you insert in your system’s floppy disk drives are round pieces of flexible plastic coated with magnetic material and enclosed in protective jackets. Like a record, a diskette has circular tracks on both sides. The computer stores the data you enter as magnetic patterns on these circular tracks. A small read/write head in the disk drive interprets the magnetic pat- terns. When a diskette is in a drive, the read/write head is right over the large oval hole in the diskette jacket. This hole allows the read/write head to access the diskette when yo..
l l l l l l l l l l Keep disks away from magnetic fields. (Remember that disks store their information magnetically.) There are many sources of magnetism in and around your home or office, such as electrical appliances and tele- phones, and particularly loudspeakers. Keep disks in a moderate environment. They work best at normal room- temperature and humidity conditions. Never leave them sitting in the sun, or in extreme cold or heat. The temperature inside a car in the middle of summer or winter can cause severe damage. Never touch the diskette’s magnetic surface. The oils on your finger..
l Never attempt to open the hard disk unit. The disk itself is enclosed in an air-tight container to protect it from dust. l If you plan to move the hard disk unit, the read/write head must be moved away from the disk recording area. The MS-DOS program to protect the read/write head is HDSIT. Refer to your Diagnostics or MS-DOS manual for details. Inserting and removing diskettes To insert a diskette into a disk drive, hold it with the label face up and the write-protect notch to the left (so that the read/write slot is away from you). Then slide it into the disk drive as shown in Figure 2-..
Note: You need to format your blank diskettes before you can use them with your operating system. Refer to your MS-DOS or other operat- ing system manual for instructions on how to format your blank diskettes. There are two ways to avoid losing the valuable information stored on your disks; write-protect your diskettes and make backup copies. Both of these methods are described below. Write-protecting diskettes You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can copy data from it, but you cannot store new data on the diskette ..
Write-protected Write-protect - switch Figure 2-5. Write-protect switch To unwrite-protect a 31/2” diskette, move the switch up toward the center of the diskette so the hole is covered. Making backup copies It is a good idea to make copies of all your important data and program diskettes. With program diskettes, or the system master diskette supplied with your Equity I + , you should use backup copies, and keep the originals in a safe place-away from your working disks. Copy your data disks regularly (preferably daily), and keep them apart from the originals. Your MS-DOS manual describes ..
An operating system expects the computer to have at least two physical disk drives. MS-DOS recognizes drives A and B for two floppy disk drives, or A and C for a floppy and a hard disk drive. Some operations, such as copy- ing files from one disk to another, require two drives. With MS-DOS, if you have only one physical disk drive, the operating system lets you treat it logi- cally as two drives. For example, if you give a command to copy from drive A to drive B, MS-DOS copies from the first diskette you place in the drive (A) to the computer’s memory. Then it prompts you to insert the di..
Before you use the Epson internal hard disk, you must do the following things to prepare it: l Use the Format Hard Disk program on your diagnostics diskette to format the hard disk. l Partition the hard disk to run the MS-DOS operating system using the MS-DOS program FDISK. l Format the MS-DOS partition with the MS-DOS program SELECT. l Copy the MS-DOS utility programs to the hard disk using SELECT For instructions on running the diagnostics program, see your Diagnos- tics manual. For instructions on how to use the MS-DOS programs, refer to your MS-DOS manual. If you plan to use an operatin..
Chapter 3 Installing Option Cards Option cards are accessories you can add to your Equity I+ to provide extra system capabilities. For example, you may want to install a memory expansion card or an auto-dial modem. You can install up to five option cards in the Equity I+ at one time, but one position is always occupied by the video card that operates your moni- tor. Option cards are available from Epson as well as other vendors. In addi- tion, multifunction boards (available from other vendors) allow you to add other features without using additional slots. Consult your Epson dealer for mor..
2. The back panel is secured with three screws as shown in Figure 3-1. Remove the screws and put them to one side. Slip the back panel off the main unit. 3. Screws Figure 3-1. Back panel screws The top cover is secured by two screws on each side of the computer as shown in Figure 3-2. The two screws on the left side of the unit are covered by small plastic inserts. Gently remove the inserts with a small screwdriver, then remove the screws on both sides of the computer. Put the screws and inserts safely to one side. Figure 3-2. Side screws under plastic inserts 3-2..
4. Tilt the cover up slightly from the back and pull it toward you and away from the main unit, as shown in Figure 3-3. Set the cover aside for now. Figure 3-3. Removing cover Inserting the Option Card The video card must be placed in the qh slot. Figure 3-1 shows the cor- rect placement of a video card. Most other option cards can be placed into any of the four remaining option slots, but some cards may need to be in- stalled in a specific slot. Check the option card manual to find out if the option card has to be in a specific slot. Even though option cards are designed to fit only one wa..
Note: Pay specific attention to the warnings in your option card instructions. Some devices have delicate CMOS chips you should not touch. When you handle the card, be careful not to touch any of the contacts on the circuit board, especially along the gold edge connections. If you need to put it down before installing it, place it with the component side facing down on top of the original packing. Keep the card’s original packing materials in case you remove the card later. 3. Grip the card firmly by the top corners. The contact pins should be pointing down and the components should face ..
6. Secure the retaining bracket to the frame of the computer with the small screw and washer. Also replace the ground screw if there is one. The free end of long option cards is held in position by a piece of foam inside the top of the main unit lid and by the card bracket on the inside of the front panel. Removing an access slot cover Some option cards, such as your video monitor card, have an outlet for connecting an external device. If you install an option card that has an exter- nal connector for other equipment, (your video monitor, for example), you need to remove the metal access sl..
Replacing the Cover With the option card properly installed or removed, the last step is to replace the cover of the main unit: 1. With the back of the main unit facing you, position the cover over the computer with the side feet to the left of the main unit and the front edge pointing slightly downward. 2. Lower the cover onto the bottom half of the case, as shown in Figure 3-6, making sure that the bottom edges fit inside the case. At the same time, slide the front edge beneath the top edge of the front panel. Finally, lower the back of the cover so that it is in position. Figure 3-6. Rep..
Post-installation Setup After you install an option card (and replace the main unit’s cover and reconnect the power cord and peripherals), you may need to change your DIP switches to update the configuration information. For example, if you add a floppy disk drive, you need to change switches 1-7 and 1-8 so the computer knows it has the additional drive. You may also need to add some commands in the configuration files on your system disk as well. See your MS-DOS manual for instructions. When you finish installing an option card and reconfiguring the system, you should test the option if ..
Chapter 4 Troubleshooting You should not encounter any serious difficulties with the Equity I+, but if anything out of the ordinary does happen, this section should help. Such a situation usually requires nothing more than repeating a software procedure, correcting an operating system error, or resetting the computer. Most of the minor difficulties you might encounter can be resolved by one of the suggestions below. If none of these solves the problem, consult an Epson dealer about servicing the computer. WARNING: If the computer has to be turned off for any reason, always wait at least fiv..
2. Use the controls on the monitor to adjust the brightness and contrast. 3. Check DIP switches 1-5 and 1-6 on the front of the main unit to make sure they are set correctly for your monitor. 4. Remove any diskettes, then turn off the monitor and main unit. Check to see that the monitor power cable is securely connected to the electri- cal outlet, and that the monitor cable is properly connected to both the monitor and the main unit. Turn both power switches on again. 5. With the computer turned off, check the electrical outlet for power. Plug a portable lamp into the outlet you are using f..
3. Is the diskette write-protected? A write-protect tab or switch may be in place to protect the data on the disk. Think twice before removing the tab or moving the switch. It might be a new diskette, but it might also be a diskette with information you do not want to change or lose. Check the diskette directory to determine what files it contains. The operating system manual gives the proper directory command. Although you should normally write-protect program diskettes, there are some pro- grams which use the program diskette for temporary files, and these do not work if the diskette has ..
l Some programs, for compatibility reasons, may require the computer to run at 4.77MHz. Try changing the CPU speed with the switch on the front panel. See “Selecting Execution Speed” in Chapter 2. Printer Problems Most of the problems encountered while using a printer can be solved by checking the manual that came with the printer. If the printer is not working correctly and has just been installed, first make sure the printer has power and is correctly connected to the computer. The printer manual provides instructions on cable connections. If you have a serial printer, or if you have ..
Appendix A Changing Jumper Settings This appendix describes how to set the jumpers inside the Equity I+ if you install optional devices that require different jumper settings than those set by the factory in the main unit. It is best if your dealer installs the option and makes all necessary adjustments when you buy it. If you decide to do it yourself, be very careful when you follow the procedures in this appendix. There are many system components which can be damaged accidentally. Jumpers are small electrical connectors that alter some of the computer’s functions. A jumper’s setting i..
For detailed instructions on how to connect the drives to the optional floppy disk controller card, consult the documentation supplied with the card itself. The drive cables for drives A and B are normally connected to connector CN5 on the system board (shown in Figure A-2). If a different cable was supplied to connect the drives to the optional controller card, make a careful note of how the original drive cable was connected, and remove it from the computer. Keep it in a safe place, in case you need to remove the optional controller for any reason. FRONT J2 / 6M and 6N / 7M and 7N Figure ..
Jumper J2, Parity RAM Parity RAM enables the computer to make sure that the data stored in its memory is valid. The Equity I+ can support parity RAM to give you added protection against loss of data. Installation of parity RAM is a simple process, but you should ask your dealer to do it for you, as well as test the RAM carefully. If you decide to install the parity RAM yourself, follow the instructions below carefully. You need to install four RAM chips. After you remove the cover of the computer (see “Removing the Cover” in Chapter 3) locate sockets 6M, 6N, 7M, and 7N. See Figure A-2. ..

Introduction This manual describes how to initialize your Epson ® Equity™ I+ after it is assembled, and how to test the condition of your computer and peripherals. To set up and test your system, you use a set of programs called diagnostics. The five main diagnostics programs are: Setup Use this program when you first set up the computer, and any time you change the system’s permanent date or time or the serial port configuration. Format hard disk Format diskette Use this program to check or format the entire hard disk after installation. Use this program to format a diskette for use b..
Chapter 1 describes how to start the diagnostics programs, select options from the menus, and exit the programs. Chapters 2 through 6 describe each of the five programs individually, and Chapter 7 describes the three system- dependent utilities (HELP ROMBIOS, and SYSTAT). Appendix A lists the error codes and messages that may appear during diagnostics checks, and Appendix B explains the power-on diagnostics messages. Intro-2..
Chapter 1 Running the Diagnostics This chapter describes how to start and use the diagnostics programs. Starting the Diagnostics To start the diagnostics programs, follow these steps: 1. Turn off the computer and wait for a few seconds. 2. Place the diagnostics diskette in drive A, and secure the disk drive. 3. Turn on the computer. The computer tests itself, and then automatically starts the diagnostics. The Power-on Self Test Whenever you turn on or reset the computer, the system performs some built-in diagnostics called the power-on self test. This test checks the RAM (random access memo..
The OPERATION MENU After the power-on self test completes successfully, the diagnostics start and you see the OPERATION MENU: OPERATION MENU 1 - S e t u p - Format hard disk ; - Format diskette 4 - System diagnostics 5 - Prepare hard disk for moving j2 - Exit to DOS fur more utilities Enter selection number: You select one of the diagnostics programs by pressing a number from 1 to 5 and pressing Enter. This manual describes each menu item in the order listed on the OPERATION MENU. Option 3, Format diskette, is included on the OPERATION MENU for convenience only. This option lets you format ..
l If you have run a diagnostics program, you see this selection on the OPERATION MENU: 0 - Exit and reset In this cast, when you press 0 and Enter, the system is reset. Before selecting this option, remove the diagnostics diskette from drive A and insert your system diskette so the system can hoot normally. If you want to hoot from your hard disk, make sure no diskette is inserted in drive A. Diagnostics and MS-DOS Commands Each choice on the OPERATION MENU corresponds to an MS-DOS command: OPERATION MENU Choice MS-DOS Command Setup SETUP Format hard disk HDFMTALL Format diskette FORMAT Sys..
You can also execute the commands directly from the diagnostics diskette, without loading diagnostics. For example, if you are logged onto drive C, and you want to prepare your hard disk for moving, follow these steps: 1. Insert the diagnostics diskette into drive A. 2. At the C) prompt, type: A:HDSIT 3. Press Enter. To use the System diagnostics program, DIAGSYS, you must always boot the system with the diagnostics diskette in drive A. If you attempt to start this program in any other way, the tests may produce strange results. 1-4..
Chapter 2 Setting Up the System This chapter describes how to change the information stored in the computer’s CMOS RAM. You can select Setup from the OPERATION MENU, or you can execute the MS-DOS SETUP command. You must run the Setup program when you turn on your computer for the first time. You also need to use Setup if you want to: l Permanently change the real-time clock’s date or time l Change the default settings for the serial (RS-232C) port(s). The information you define with Setup is stored in the CMOS RAM, which is backed up by a battery. Whenever you turn on the computer, it s..
When you start Setup, the main menu is displayed: Select options from this menu using t and 1 to move the cursor block. When the selection you want is highlighted, press Enter. Each option on the main menu (except Exit) displays another menu of choices. After making your selections on the submenu, you can exit in one of the following ways: l To exit the submenu without making any changes, press f until the cursor block returns to the main menu, or simply press ESC. This cancels any changes you just made to the configuration. l To set your changes, press 1 to highlight ** SAVE SETTINGS ** an..
When you finish using the Setup program, select the Exit option from the main menu. The program displays a list of the current settings you just made. Check the list before placing the settings in CMOS RAM. Below the list you see this menu: m Change settings m Exit without saving ** EXIT AND SAVE ** If any setting is incorrect, press Enter. The main menu is displayed again, and you can correct the setting. If you did not make any changes, or if you want to cancel the changes you made, you can return to the OPERATION MENU or the MS-DOS prompt without re-booting the computer. Press 1 to highl..
To set the real-time clock, follow these steps: 1. On the main menu, press 1 to move the cursor block to Real-time clock and press Enter. You see the time and date displayed like this: 19:lt5:55 -Time- 12-31-1986 Date 2. To set the time, move the cursor to Time and press Enter. You see: hh:mm:ss Enter the time in the exact form shown in the box, using two digits for each part; the program automatically inserts the colons (:). When the time is correct, press Enter. If you enter an invalid time, the computer beeps, and the time does not change. 3. To set the date, move the cursor to Date and ..
Changing Serial Port (RS-232C) Settings Use the Primary serial port and Secondary serial port options to change the default parameters for the serial ports installed in your computer. The primary serial port is the one that you refer to in MS-DOS as COM1: - normally the built-in serial port. You might use this port for a serial printer, or an external modem. The secondary serial port is the one you address as COM2: - normally a serial port on an option card. This might be the name used for an internal direct modem. For example, if you have a serial printer attached to the built-in serial po..
Move the cursor to the desired communication speed and press Enter. To set the type of parity check, move the cursor to Parity and press Enter. The screen displays: I I None Odd Even Move the cursor to the correct type of parity check and press Enter. To change the data length, move the cursor to Data length and press Enter. The number changes to either 7 or 8, whichever was not displayed before. Press Enter again if you want to reselect the previous number. To change the number of stop bits, move the cursor to Stop bits and press Enter. The number changes to either 1 or 2, whichever was no..
Chapter 3 Formatting a Hard Disk This chapter describes how you check or format a hard disk drive after installation. After the hard disk is formatted, it can be partitioned and for- matted for a particular operating system. Formatting destroys all data on the hard disk, in all partitions, so use this program with extreme care. Format hard disk is option 2 on the OPERATION MENU. You can select this option from the OPERATION MENU, or you can execute the MS-DOS HDFMTALL command. After you install a hard disk drive, format it using this program, Format hard disk, and choose option 1, Condition..
The first two options format a hard disk. Normally you use option 1, Conditional format (Normal). This option automatically locates any bad tracks that are Pug& by the manufacturer and marks them so that they are never used. Option 2, Unconditional format, requires you to enter the list of bad tracks. The other two options test a hard disk for problems. Use option 3, Destructive surface analysis, to test the entire disk and update the bad track table. Because this option writes data to the disk as well as reads it, all data on any track that produces an error is destroyed. To check for ..
Conditional Format (Normal) Use this option to format the hard disk. All flagged tracks are marked so that they are never used. To start the Conditional format, press 1 and then Enter. The program starts to scan the disk to find all tracks flagged as bad, starting from the innermost cylinder of the disk. During the scan, you see the number of the cylinder being checked. For example, if you have a 20MB hard disk, the first messages you see are: Format Hard Disk Scanning for flagged bad tracks... Current cylinder is 614 When the scan is complete, the program displays information about the con..
If you cancel formatting at either stage, you see these messages: Format cancelled. Press ENTER to return to the menu. If you continue with formatting, you see: Now formatting . . . When formatting is complete, any bad tracks are flagged, and you see a series of messages like these: Format finished. Flagging bad tracks... Cylinder is xxxx, head is yy Format completed. Press ENTER to return to the menu. Flagged tracks are identified by xxxx and yy. At this point, press Enter to return to the HARD DISK FORMAT MENU. If there are any tracks with other errors, scanning stops and you see the mess..
Unconditional Format Use this option to format your hard disk when you want to enter the list of bad tracks before formatting begins. The main difference between uncon- ditional and conditional formatting is the way in which bad tracks are identi- fied. With the unconditional format, you must enter the list of bad tracks before formatting begins. To start the Unconditional format routine, press 2 and then Enter. You are first given the option to change the interleave factor for format- ting from the default value of three. Only do this if the documentation with your hard disk recommends a d..
To add a bad track, follow these steps: Press A. You see this prompt: Enter cylinder number (1 - xxxx): Type the number of the cylinder containing the missing bad track, and press Enter. You see this prompt: Enter head number ($3 - yy): Type the head number for the bad track, and press Enter. The maxi- mum valid cylinder and head numbers ( XXXX and yy) vary according to the type of the hard disk. To cancel this operation, press Enter without entering a value. You see this message: Table unchanged. If you enter an invalid cylinder or head number, a reminder of the range of values is displaye..
This test operates by a complex process of writing, reading, and verifying information on every track of the hard disk, except for tracks that are already flagged as bad tracks. To start the test, press 3 and then Enter. You see these messages: Analyze Hard Disk Read/Save/Write/Read/Restore/Read check for all tracks... Current cylinder is xxxx As each track 1. ,.h~~.k~~i, tl IC c i IIK cr number (XX& counts down to zero. .%.I. i When the analysis is complete, the program displays a complete report on the status of the disk, including a table of unflagged tracks that produced write, read..
To flag the error tracks as bad, press Y and Enter. You then see a list of the tracks as they are flagged. You see these messages: Flagging bad tracks... Cylinder is 237, head is 2 Press ENTER to return to the menu. Press Enter to return to the HARD DISK FORMAT MENU. Non-destructive Surface Analysis The Non-destructive surface analysis is slightly simpler than the Destructive surface analysis described in the previous section. This option does not destroy any data, and can safely be used to check the condition of your hard disk drives. However, this test will not flag any bad tracks that ar..
Chapter 4 Formatting a Diskette This chapter briefly describes how to format a diskette with diagnostics. Normally, you format a diskette using the MS-DOS FORMAT command. However, if you are running diagnostics and decide to test your floppy drives (which requires a formatted diskette), you can select option 3, Format disk- ette, from the OPERATION MENU. This option lets you format a 360KB double-density or a 720KB high-density diskette without exiting diagnostics. The Format diskette program destroys any data on the diskette. When formatting your diskettes, the program also initializes the..
Chapter 5 Performing System Diagnostics This chapter describes how to check the operation of the main unit and peripheral devices of your Equity I+. You check these devices using System diagnostics, option 4 on the OPERATION MENU. Always run diagnostics after adding or removing optional devices, or if you are unsure whether a device is performing correctly. You should also run these tests after moving your computer from one place to another, and after you replace the internal battery Note: To run System diagnostics, boot your system with the diagnostics diskette in drive A. Then select opti..
Using the System Diagnostics Program When you start the System diagnostics, the computer checks: l The setting of the DIP switches on the front panel l The positions of the internal jumpers l The peripheral devices that are connected to the system. After these items are checked, you see a list of the devices available for testing. This list includes only the devices that are installed in the system, and looks something like this: 9 - Parallel port (pr9 2 - Serial port ~(RS-22 - Dot-matrix pri 17 - Hard disk drfires4 Is the DEVICE LfST corr If the list correctly describes your system, press ..
Modifying the DEVICE LIST If an installed device is missing from the DEVICE LIST, it is important that you add it to the list and test it carefully. In response to this prompt: Is the DEVICE LIST correct (Y/N)? press N followed by Enter. You see a new menu: Modify DEVICE LIST 1 - Add devices 2 - fiel+te devices 0 - Exit Enter selection number: To add a device to the list, press 1 and then Enter. The program displays a list of other devices that are not currently included in the DEVICE LIST. Y ou see a menu similar to this: Additional DEVICE LIST 5 - Color graphics display adapter and CRT 7 ..
Type the number of the item you wish to add and press Enter. That item disappears from the Additional DEVICE LIST on the screen. You can add as many devices as necessary. When you finish adding devices, press 0 and Enter to return to the Modify DEVICE LIST menu. Note: Even if you have both monochrome and color monitor video cards installed, you can only test the monitor that is currently selected by DIP switches 1-5 and 1-6 on the front panel. To remove a device from the list, press 2 and Enter. The screen displays the current DEVICE LIST and the prompt: Enter the number of the item to dele..
You can specify that the test be performed one time only or any number of times in the range from 1 to 9999. Running a test multiple times is for reliability testing of essential functions only; in most cases, running a test only once is sufficient. To perform the test once only, press 1 then Enter. The program displays a submenu of more detailed tests for the device you are checking. To perform the test multiple times, press 2 and Enter. You see this prompt: Terminate checking if an error detected (Y/N)? Press Y and Enter to terminate checking if the device produces an error, or press N an..
The program continues after an error in one of the following ways: l It returns to the DEVICE LIST, or l If you are running multiple tests and are not terminating on an error, the program repeats the test that caused the error. The remainder of this chapter describes the tests you can run on the system’s internal devices and on the optional devices installed in your com- puter. The program displays the title of each check on the screen. For a complete list of the error codes and messages that are displayed by these tests, refer to Appendix A. System Board Check Use this option to check th..
For this check, the program writes specific data into memory and then reads it back. The data is written and read in blocks of 64KB. A parity check is also made on each block. A count of memory is displayed after each block that is tested without an error. The final message is usually: 640 KB OK If an error is reported, write down the error code and message, or print them out, and contact your Epson dealer. Attempting to correct memory errors yourself may violate your warranty agreement. Keyboard Check Use this option to check the operation of the keyboard. The program first checks the keyb..

Sequential seek check This test checks the ability of the read/write heads to locate any part of the diskette. This action by a read/write head is called a seek. During this test, each head seeks sequentially from the innermost track to the outermost track. The innermost track is track 39 for 360KB diskettes and track 79 for 720KB diskettes. Select option 1 from the menu to start this test. The program displays th..
Use only a formatted blank diskette for this test. Any data present may be erased. If using drive A, remove your Diagnostics Disk. Enter Y to start this check. Enter N to return to the menu. Make sure the blank diskette you prepared is in drive A, then press Y and Enter. The program displays the current track number as each cylinder is tested. For example, with a 720KB floppy disk, the first message you see is: Current track is 79 Speedcheck This test checks the revolution speed of the specified disk drive. Select option 4 from the menu to start this test. You see a message similar to this:..
When you choose this option, all checks for the floppy disk drive(s) and controller are performed automatically in sequential order. Although you do not start each test, you must still supply the appropriate responses to progress from one test to the nest. Math Coprocessor Check (8087) Use this option to check the operation of the 8087 math coprocessor if you have one installed in your computer. To check the math coprocessor, select option 7 from the DEVICE LIST Before running any tests, the computer checks DIP switch 1 - 2 on the front panel to ensure that a coprocessor is installed. If th..
Parallel Port (on Video Adapter) Check Use the Parallel port (on video adapter) check to test the functions of the primary port. This tests either the built-in port, if it is set up to act as the primary port, or the parallel port on a monochrome adapter (such as the IBM monochrome display and printer adapter) if you have one installed in your computer. To perform the test, you must insert the special loop-back connector into the parallel port so that the computer can check individual pins of the port. This test is identical to the Parallel port check. For more details, refer to the descrip..
Each baud rate is tested in turn, and the display informs you of the progress of the test. If the port does not become ready correctly, a timeout error occurs. If any data received does not match the data sent, a verify error occurs, and the computer reports the transmitted and received data at the time of the error. The final test is an echo back check during which the port sends data to itself at 9600 baud, using various data formats. At the start of the test, you see these messages: RS23X echo back check - with various data formats Current data format: 5 data bits, 1 stop bits, parity - ..
Check that your printer is connected to the computer, and that it is turned on, loaded with paper, and on-line. Press Y and then Enter to continue, or press N and Enter to return to the menu. When you continue the test, the computer checks that the printer is responding correctly. This test detects whether the printer is off-line or whether an interface error exists. If no errors occur, the computer sends a repeating sequence of ASCII h c aracters and bit-image data to the printer until you press any key. The pattern looks like this: Text data (ZOH-7FH,AOH-FFH) '"X$~&'()~+,-./0123456789..

In this case, back up all your files, and have the drive serviced immediately. (The drive may be corrupting your data.) Read, verify check This test reads and verifies data from all tracks of the disk, checking each cylinder and using both heads. Select option 4 from the menu to start this test. The program displays the number of each cylinder it finds. For example, with a 20MB hard disk, the first message you see is: Current cylinder is 614 The c..
Chapter 6 Moving the Hard Disk This chapter describes the procedure you use when you plan to move your computer. Even if you are moving the computer only a short distance, use option 5, Prepare hard disk for moving, to prevent damage to the hard disk. For each hard disk installed in the system, this program ensures that the read/write heads are moved away from the disk surfaces and locked securely in position. If the heads are not secured and the computer is subjected to shock or vibration, the heads may bump the disk surfaces and the drive may be damaged. At the very least you may lose a c..
Chapter 7 System-dependent Utilities This chapter describes the utilities that are included on your diagnostics diskette. These utilities are used exclusively by your Equity I+ system: HELP ROMBIOS SYSTAT Each utility is an MS-DOS command.

Appendix B Power-on Diagnostics The built-in memory (ROM) of your computer contains a series of diag- nostics programs. These programs are run automatically by the system every time you turn on the power. The diagnostics programs check the internal devices such as ROM, RAM, keyboard controller, timer, video controller, and floppy disk driver. When you turn on the power, the tests described in this appendix are performed. If an error is found, a specific error number and error message are displayed. If the error is serious, the computer cancels further checking and halts system initializatio..
