Page 83: How Disks Store Data
Write-protect diskettes Make backup copies of your diskettes Use a single diskette drive Use two diskette drives Use a hard disk drive. How Disks Store Data The diskette you insert in your computer’s diskette drive is made of flexible plastic coated with magnetic material. It is enclosed in a square jacket that is either slightly flexible (5 ¼-inch diskettes), or hard (3 ½-inch diskettes).
Page 84 A disk is further divided by sectors. To understand what a sector is, picture the spokes on a bicycle wheel radiating from the center of the wheel to the tire. The space between one spoke and the next is like a sector on a diskette; the lines dividing the sectors cut across the tracks.
Page 85: Types Of Diskette Drives
Types of Diskette Drives The Equity 386/25 comes with one 1.2MB diskette drive. With this drive, use 5 ¼-inch, double-sided, high-density, 96 TPI, 1.2MB diskettes. These diskettes contain 80 tracks per side, 15 sectors per track, and hold up to 1.2MB of information, which is approximately 500 pages of text.
Page 86 Drive and diskette incompatibilities If your computer has more than one type of diskette drive, or if you use diskettes from other computers with other types of diskette drives, you need to be aware of certain incompatibilities between the diskette drives and the diskettes they use. Because of the size difference, you cannot use 3 ½-inch diskettes in a 5 ¼-inch drive or vice versa.
Page 87: Caring For Diskettes And Diskette Drives
Because of these incompatibilities, always indicate the diskette type and density when you label your diskettes. (Usually this information appears on the manufacturer’s label.) If you have any combination of the above drives (1.2MB, 360KB, l.44MB, or 720KB), you can copy files from one drive to another-using the COPY or XCOPY command-as long as the correct diskette type is in each drive.
Page 88 Never wipe, brush, or try to clean diskettes in any way. Keep diskettes in a moderate environment. They work best at normal room temperature and in normal humidity. Don’t leave diskettes sitting in the sun, or in extreme cold or heat. Keep diskettes away from magnetic fields.
Page 89: Inserting And Removing Diskettes
For a 5 ¼-inch diskette, it is best to write on a label before you attach it to the diskette. If you need to write on a label that is already on a 5 ¼-inch diskette, use only a soft-tip pen-not a ballpoint pen or a pencil.
Page 90 To remove the diskette, turn the latch up until it is horizontal and the edge of the diskette pops out. Carefully pull out the diskette, place it in its protective envelope, and store it in a proper location, such as a diskette container. If you have a 3 ½-inch diskette drive, insert the diskette with the label facing up and the metal shutter leading into the drive, as shown below.
Page 91: Write-Protecting Diskettes
Write-protecting Diskettes You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can read it and copy data from it, but you cannot store new data on the diskette or delete any files it contains. If you try to change data stored on a write-protected diskette, MS-DOS displays an error message.
Page 92: Making Backup Copies
On a 3 ½-inch diskette, the write-protect device is a small switch on the back of the diskette in the lower right corner, shown below. To write-protect a 3 ½-inch diskette, slide the switch toward the edge of the diskette until it clicks into position, exposing a hole in the corner.
Page 93: Using A Single Diskette Drive
To make backup copies of your diskettes, use the DISKCOPY command, the MS-DOS Shell, or the MENU program. See Chapter 4, your Shell User’s Guide, or your MS-DOS Reference Manual for instructions. It is best to store the programs and data files you use regularly on the hard disk.
Page 94: Using Two Diskette Drives
For example, if you enter a command to copy from A to B, MS-DOS copies from the first diskette you place in the drive (A) to the computer’s memory. Then MS-DOS prompts you to insert another diskette (for drive B) and copies from memory to the new diskette.
Page 95: Using A Hard Disk Drive
Using a Hard Disk Drive Working with a hard disk is similar to working with a diskette. However, the hard disk provides several advantages: A 40MB hard disk can store as much data as approximately 331.2MB diskettes, and a 100MB hard disk can store as much data as approximately 82 1.2MB diskettes.
Page 96 Never attempt to open the hard disk drive. The disk itself is enclosed in a sealed container to protect it from dust. Before you move your computer (even to another part of the room), you need to prepare the hard disk for moving. See “Preparing the hard disk for moving,”...
Page 97: Turning Off The Computer
Preparing the hard disk for moving If you need to move your computer to a new location-whether it is across the country or just across the room-you should run the HDSIT program to protect the hard disk during the move. The HDSIT program moves the disk drive’s read/write heads to a region on the disk surface that does not contain data, and locks them securely in position.

Formatting diskettes B a c k i n g u p d a t a Using the MS-DOS Shell program Using the Epson HELP and MENU programs Using an AUTOEXEC.BAT file Using the video shadow RAM function Using memory beyond 640KB.
Page 99: Starting Ms-Dos
Starting MS-DOS Before you can run an MS-DOS application program, MS-DOS must be loaded in the computer’s memory. If you have a hard disk and you installed MS-DOS according to the instructions in your MS-DOS Installation Guide, the computer loads MS-DOS automatically after you turn on the power (provided no diskette is in the diskette drive).
Page 100: Using Drive Designators
Using Drive Designators MS-DOS uses letters known as drive disk drives in your computer. If you have one diskette drive, it is known as drive A. If you have two diskette drives, the top drive is A and the bottom drive is B. If you have one hard disk drive, MS-DOS identifies its primary partition as drive C (even if you have only one diskette drive).
Page 101: The Current Drive
The Current Drive At any given time, MS-DOS considers one disk drive to be the current (or default) drive. The current drive is the drive on which MS-DOS executes your next command, unless you tell it to do otherwise. For example, if the current drive is C, and you enter the DIR (directory) command, MS-DOS lists the files stored on drive C.
Page 102: Types Of Ms-Dos Commands
Specifying the drive designator If you want to access a program or file on another drive without first changing the current drive, type the drive designator along with the filename. For example, if you are logged onto drive A and want to use a file named PROGRAM on drive B, type B : PROGRAM and press Enter.
Page 103 If you do not have a hard disk, external commands are stored on the set of working diskettes generated when you installed MS-DOS. To use an external MS-DOS command, you must insert the diskette containing that command into a diskette drive.
Page 104: Entering An Ms-Dos Command
Entering an MS-DOS Command To enter an MS-DOS command, you need to type the command in the correct format. The command format provides MS-DOS with the information needed to perform a task. The MS-DOS command format consists of the command name, parameters, and delimiters.
Page 105: Setting The Date And Time
See your MS-DOS Reference Manual for more information on the command format and for command descriptions that explain which parameters and delimiters are required and which parameters and switches are optional for each command. You can enter an MS-DOS command whenever you see the MS-DOS command prompt.
Page 106: Creating And Managing Files
Creating and Managing Files All your data and programs are stored in files on disk. A data file contains information, such as words, numbers, or pictures. A program file contains coded instructions that the computer can understand and execute. The kind of file you create depends on the MS-DOS command or application program you use to create it.
Page 107 The extension is optional and can be up to three characters long. You can use the extension to further identify a file or to describe what type of file it is, such as a text file or program file. When you use an extension, separate it from the filename with a period, like this: DATA.TXT Do not use uppercase and lowercase letters to distinguish...
Page 108: Copying Files
Copying Files You can use the COPY command to copy individual files or groups of files. COPY is an internal command; you can use it any time you see the MS-DOS command prompt. You can use the COPY command to copy files in several ways: You can copy individual files from one disk to another You can copy a group of files using You can copy one or more files and give them new names...
Page 109 To copy the file named REPORT to the same drive or directory and name the copy FACTS, type the following and press Enter: COPY REPORT FACTS Now you have two files on the current drive that have the same contents but different names. In this example, you can omit the drive designators because the original file and the copy are both on the current drive.
Page 110 To copy REPORT, FACTS, and MEMO from drive A to a file named DATA on drive B, type the following and press Enter: COPY A:REPORT + A:FACTS + A:MEMO B:DATA Remember these rules when using the COPY command: MS-DOS must be able to find the original file and know where to store the copy;...
Page 111: Renaming Files
Renaming Files You can use the RENAME command to change the name of a file or group of files on the same disk and directory. For example, to rename a file named PROSPECT (in the current directory) to CLIENT, type the following and press Enter: RENAME PROSPECT CLIENT You can shorten the RENAME command to REN.
Page 112: Deleting Files
Deleting Files You can delete files you no longer need with the DEL (delete) command. For example, to delete REPORT.AUG from drive C, type the following and press Enter: C:REPORT.AUG To delete the file WRENCHES from drive C, type the following and press Enter: C:WRENCHES To display a prompt asking you to confirm that you want to...
Page 113: Printing Text Files
Printing Text Files If you have a printer attached to your computer, you can print text files with the PRINT command. In general, you will probably use application programs to print files, but if you need to print a text file from the MS-DOS command prompt, follow the steps below.
Page 114 Directories are essential for organizing files on a hard disk, and you might even want to create directories on a 1.2MB diskette. However, you may not need to create directories if you use lower capacity diskettes-especially if the diskette contains only a few large files.
Page 115 This directory tree lets you separate business word processing files from personal word processing files, and sales spreadsheets from spreadsheet files used for financial projections. Your directory structure may be as simple as this example or much more complex. Organize your disk(s) to suit your needs. As your needs change, you can modify the structure by deleting old directories and creating new ones.
Page 116: The Current Directory
The Current Directory MS-DOS always recognizes one directory as the default) directory, just as it always recognizes one drive as the current drive. The current directory is the directory you are logged onto at the time and the one in which MS-DOS performs your commands, unless you tell it to do otherwise.
Page 117: Using Pathnames
Using Pathnames You use pathnames with MS-DOS commands to tell MS-DOS how to find its way to the directory you want to access. Backslashes separate the directories in a pathname. There are two types of pathnames: absolute and relative. An absolute pathname begins with a backslash and tells MS-DOS how to find its way to the desired directory from the root directory.
Page 118: Including Filenames With Pathnames
You can use either relative or absolute pathnames at any time, as long as you give MS-DOS enough information to find the directory or file at the end of the pathname. Including Filenames With Pathnames You can use a pathname when you want to access a file that is not in the current directory.
Page 119 drive C, the root directory was the current directory. Now you are logged onto drive A and you enter the following command to delete the file JEAN1204.DOC: DEL C:JEAN1204.DOC MS-DOS tries to find the file you want in the root directory of drive C.
Page 120: Creating Directories
Creating Directories You use the MKDIR command to create directories. For example, to create a LEDGER di rectory under the root directory of the current drive, type the following and press Enter: MKDIR \LEDGER You can abbreviate the name of this command to MD. For example, to create a SALES directory under the LEDGER directory, type the following and press Enter: MD \LEDGER\SALES...
Page 121 A directory listing includes the following information about each file in the directory: Name and extension Size of the file in bytes Date and time the file was created or last modified (whichever is later). The directory listing also shows any subdirectories in the directory;...
Page 122: Displaying A List Of Directories
This switch displays a wide-format directory listing, like this: Volume in drive C is MEMODRIVE Volume Serial Number is 354C-12E9 Directory of 5 File(s) This type of listing does not show the size of a file or the time and date it was last modified. To list the contents of a different drive or directory, include the appropriate drive designator and/or pathname in the command.
Page 123 The screen displays a tree diagram of the subdirectories of the current directory, for example: To see a list of all the files in the subdirectories, add the /F switch, like this: TREE /F The screen displays the directory information shown above and the names of all the files in each subdirectory: 4-26 Using MS-DOS with Your Equity 386/25...
Page 124: Removing Directories
To see the list of subdirectories of another directory, include the pathname: TREE Removing Directories You may sometimes want to remove directories you no longer need. However, before you can delete a directory, it must be empty. If it contains any files or subdirectories, MS-DOS displays an error message and does not delete the directory.
Page 125: Using The Format Command
You can reformat previously used diskettes. This process erases all data on the diskette, so be sure you do not want to save any of the data on a used diskette before you format it. If you plan to use a new diskette to make a backup copy of another diskette, you do not need to use the FORMAT command to format it first.
Page 126 3. If necessary, remove the Working 1 diskette from drive A. Insert the diskette you want to format in drive A and press Enter to start formatting. 4. When the diskette is formatted, you see this message: Format complete Volume label (11 characters, ENTER for none)? 5.
Page 127: Backing Up Data
Formatting a diskette to 360KB If you want to format a 360KB diskette in your 1.2MB diskette drive, you need to use a switch with the FORMAT command. The /4 switch tells the FORMAT command to format a 360KB diskette in your 1.2MB diskette drive. Enter the following command when you follow the instructions in this section to format a diskette: FORMAT A: /4...
Page 128: Using The Diskcopy Command
DISKCOPY, BACKUP, and RESTORE are described below. “Copying Files,” earlier in this chapter, describes the COPY command. See your MS-DOS Reference Manual for information on XCOPY. Note Using the DISKCOPY Command The DISKCOPY command lets you make an exact copy of a diskette.
Page 129 Using DISKCOPY with one diskette drive 1. Make sure the diskette you want to copy is write-protected. (See Chapter 3 for instructions.) 2. If you don’t have a hard disk, insert your Working 1 diskette into drive A. 3. If you have a hard disk, type C : and press Enter to log onto drive C.
Page 130 7. After DISKCOPY copies the data from memory to the target diskette, the screen prompts you to insert the source diskette again to copy the remaining data to the computer’s memory (if necessary). Insert the source diskette into drive A and press any key. 8.
Page 131: Using The Backup Command
4. If necessary, remove the Working 1 diskette from drive A. Insert the diskette you want to copy from (the source diskette) into drive A and the diskette you want to copy to (the target diskette) into drive B. Then press any key to begin copying.
Page 132: The Ms-Dos Shell Program
Shell program and see your MS-DOS Shell User’s Guide for information on how to use it. Using the Epson HELP Program The Epson HELP program lets you display information on the screen about MS-DOS commands and programs. You can use HELP in one of three ways:...
Page 133 If you want information about more than one command you can type HELP followed by the names of the commands, each separated by a space. To use the HELP program, follow these steps: If you don’t have a hard disk, make sure your Working 3 diskette is in drive A.
Page 134: Using The Epson Menu Program
6. Press to exit the HELP program. Using the Epson MENU Program The Epson MENU program lets you display a menu of commonly used MS-DOS commands and select the one you need. It provides an easier way to run MS-DOS commands because you can execute commands without having to remember their exact syntax.
Page 135 3. To select an option, use the arrow keys to highlight the option you want and press Enter. Most options contain submenus; keep highlighting your selection and pressing Enter until you select the desired operation. MENU works by calling external commands which it looks for on the current disk or path.

Page 137: Using An Autoexec.bat File
Using an AUTOEXEC.BAT File You may want to run some commands every time you turn on your computer. To run a command or a series of commands automatically upon startup, you can type the commands in a special file called AUTOEXEC.BAT. When you load MS-DOS, it always looks for this file.
Page 138: Creating An Autoexec.bat File
Creating an AUTOEXEC.BAT File Here is an example of an AUTOEXEC.BAT file: PATH C:\;C:\DOS;C:\WP PROMPT $P$G The first line tells MS-DOS to look for programs or batch files in the root directory, the DOS directory, and your word processing directory. This way you can run programs in those directories without having to specify pathnames in the commands.
Page 139 You can also use the MS-DOS COPY or EDLIN command to create an AUTOEXEC.BAT file. Follow these steps to create an AUTOEXEC.BAT file with the COPY command: 1. If you are creating an AUTOEXEC.BAT file on your hard disk, log onto the root directory of your hard disk. (Type CD C : \ and press Enter.) If you are creating an AUTOEXEC.BAT file on your Startup diskette, insert the Startup diskette into drive A...
Page 140: Using The Video Shadow Ram Function
ROM memory. The video shadow RAM function allows your computer to update its display faster after you enter a command. This feature operates with Epson- or Paradise”:compatible VGA cards and most other EGA and VGA cards. To enable the video shadow RAM function, you must do the following: Copy the file ERAMBIOS.SYS from the Reference diskette...
Page 141 The DEVICE=ERAMBIOS.SYS line must be above the DEVICE=ANSI.SYS line in your CONFIG.SYS file to enable the video shadow RAM function. Later, if you add other command lines to the file, make sure that the DEVICE=ERAMBIOS.SYS line still remains above the DEVICE=ANSI.SYS line.
Page 142 2. To view the contents of the CONFIG.SYS file, type List command) and press Enter. You see the current CONFIG.SYS file commands preceded by line numbers, such as the following: l:*BREAK=ON 2: BUFFERS=20 3: FILES=20 4: LASTDRIVE=E 5: SHELL=C:\DOS\COMMAND.COM/P/E:256 6: DEVICE=C:\DOS\ANSI.SYS 7: INSTALL=C:\DOS\FASTOPEN.EXE is the EDLIN command prompt.) 3.
Page 143 Type DEVICE=ERAMBIOS.SYS and press Enter. Then you see the prompt for the next line: 5. Hold down CTRL and press C to exit insert mode. You see the * prompt. 6. To make sure your command line is inserted, list the contents of the CONFIG.SYS file again.

Page 145 To use expanded memory, you must modify the file disk or diskette from which you load MS-DOS. If you have a (also called an ASCII text file), you can use that program to program, load the file CONFIG.SYS, and then add the DEVICE=EMM386.SYS You can add one or more of the optional switches explained in the next section to this command line.
Page 146: Using Emm386.Sys
Using EMM386.SYS EMM386.SYS is an expanded memory manager that lets you use extended memory to emulate expanded memory so that you can use application programs that support LIM 4.0 EMS. The full syntax for the command line that activates EMM386.SYS is: DEVICE=[d:][path] [X:mmmm-nnnn] [Mx] The items in brackets are optional;...
Page 147 This example tells the computer to use 1024KB (1MB) of extended memory as expanded memory: DEVICE=EMM386.SYS The X:mmmm-nnnn parameter specifies a range of memory to exclude from the EMM386.SYS command in hexadecimal notation. EMM386.SYS does not locate its page frame or other mappable pages in this memory range.
Page 148 The Mx parameter specifies a particular address for the EMM386.SYS page frame. You specify the address by substituting a code for x from this table: For example, if you want EMM386.SYS to locate its page frame at the address C800, include this command in your CONFIG.SYS file: DEVICE=EMM386.SYS Do not use the Mx parameter unless you need to force...
Page 149: Installing Options
If you want to install a math coprocessor in your computer, ask your authorized Epson dealer to do it for you. Memory modules allow you to increase the amount of memory in your computer. This chapter briefly describes the types and amounts of memory modules you can use in the Equity 386/25.
Page 150: Adding Memory Modules
Note It is best not to add memory to the, Equity 386/25 by installing an optional memory card. Any memory card you could install is 16-bit and would cause your computer to work slower. Using memory modules is more efficient since you do not need to use one of your option slots to add m e m o r y .
Page 151 You must use only one type of SIMM in a bank. For example, you cannot install two 256KB SIMMs and two 1MB SIMMs in Bank 0; you must install four 256KB or four 1MB SIMMs. Each bank has a “partner” bank. Bank 0 and Bank 1 are partner hanks, as are Bank 2 and Bank 3.
Page 152 Remember, your system already has 2MB of memory (consisting of eight 256KB SIMMs) installed in hanks 0 and 1; so consider this when you decide how much memory to add. Do not install SIMMs in any other type of configuration than one of the types shown in the table.
Page 153: Installing Option Cards
The video card that controls your monitor occupies another slot. This leaves seven slots in which you can install option cards. You can buy additional option cards from authorized Epson dealers as well as other vendors. This section explains how to: Remove the computer’s cover...
Page 154: Removing The Cover
Removing the Cover To install an option card, you need to remove the cover from your computer. Follow these steps: 1. Turn off the computer and then any peripherals (including the monitor and printer) that are attached to it. 2. Disconnect the computer’s power cable from the electrical outlet and from the back panel.
Page 155 7. Facing the front panel, grasp the two sides of the cover and carefully pull it straight toward you, away from the back of the computer (as shown in the following illustration). You might meet some resistance from the grounding tabs on the top of the power supply, so pull firmly.
Page 156 8. After the cover’s front panel clears the grounding tabs and the power switch, separate the cover’s sides from the inside of the computer by pulling them outward slightly, as shown below. Continue pulling the cover toward you until it has cleared the power supply.

Page 158 Slots through 9 are designed for 8-bit option cards, and slots 1 through 6 are designed for 16-bit cards. As you can see below, a 16-bit card has a second connector along the bottom. Usually, it does not matter which slot an option card occupies as long as the card fits in the slot.
Page 159 Follow these steps to install an option card: Decide which slot you want to use. Then remove the retaining screw from the top of the metal option slot cover; hold on to the screw as you remove it so it doesn’t fall into the computer.
Page 160 2. Unpack the option card and adjust any switches or jumpers on it if necessary. (Check the option card instructions to see if this is necessary.) When you handle the card, be careful not to touch any of the contacts on the circuit board, especially the gold-edged connector pins.
Page 161 4. Insert the card in the slot, guiding it straight down. Once the connector pins reach the connector slot, push the card downward firmly (but carefully) to fully insert it, as shown in the following illustration. You should feel the card fit into place.
Page 162: Removing An Option Card
5. Secure the end of the card to the back of the computer with the retaining screw. Removing an Option Card If you later need to remove an option card, simply reverse the steps you followed to install it. Remove the screw securing the card to the back of the computer and pull the card straight up and out of the slot.
Page 163: Replacing The Cover
Replacing option cards To replace any option cards you may have removed, reinstall the card in the appropriate slot and secure it to the back of the computer with the retaining screw. Replacing the Cover After you install (or remove) an option card or change an internal setting, follow these steps to replace the computer’s cover: 1.
Page 164: Post-Installation Setup
3. To secure the cover, replace the five screws on the back panel and the two screws on each side panel. 4. Return the computer to its original position and place the monitor on top, if that is where you use it. Then reconnect the computer to the monitor, printer, keyboard, and any other peripherals you have.
Page 165: System Memory
Additionally, you may also need to add some commands in your configuration files. See the MS-DOS Reference Manual and the manual that comes with the option card for instructions. You may want to test a newly-installed option. Some options come with their own diagnostics test programs, and you can test others with the diagnostics programs on your Reference diskette.
Page 166: Appendix A Changing Jumper And Dip Switch Settings
Appendix A Changing Jumper and DIP Switch Settings If you change your computer’s configuration or need to alter the way your computer operates, you may need to change a jumper or DIP switch setting inside the computer. A jumper is a small electrical connector that controls one of the computer’s functions.
Page 167: Changing Jumper Settings
Changing Jumper Settings A jumper’s setting is determined by where the jumper is placed. On the main system board, the jumper can be placed either between pin 1 and pin 2 (position 1-2) or between pin 2 and pin 3 (position 2-3), as shown below: Only pin 1 is labelled on the main system board.
Page 168 The following tables list the jumper settings and their functions. Main system board jumper settings * Factory setting ** If jumper JP5 is set to position 1-2, set DIP switch 8 to the OFF position. If JP5 is set to position 2-3, set DIP switch 8 to the ON position.

Page 190: Diskette Problems
Diskette Problems If you have trouble accessing data on a diskette, try the following steps: 1. You may have inserted the diskette upside-down or it may not be inserted all the way. Remove the diskette from the drive and reinsert it with the label facing up. (See Chapter 3 for detailed instructions on inserting and removing diskettes.) 2.
Page 191 In a drive that has a storage capacity of 720KB, use 3 ½-inch, double-sided, double-density, 135 TPI diskettes. You cannot use 1.44MB diskettes in this drive. See “Types of Diskette Drives” in Chapter 3 for more information. 4. If your diskette is the right type for your drive, check to see if the diskette is write-protected.
Page 192 Is the diskette formatted? A new diskette must be formatted before you can store data on it. See Chapter 4 for instructions on formatting diskettes. If the error message still occurs, you probably have a defective diskette. Use the MS-DOS COPY command to copy the files from the diskette onto another diskette.
Page 193: Diskette Drive Problems
3. If you are still having problems with your diskette drive, try running the Diskette Drives and Controller Check described in Appendix D. If the diagnostics program indicates an error, consult your Epson dealer. Hard Disk Problems If you are having problems with the hard disk in your computer, try the following steps: 1.
Page 194 2. If you have installed MS-DOS on the hard disk but it does not load MS-DOS when you turn on the computer, it may be missing one of the MS-DOS system files. Turn off your computer and insert your Startup diskette into drive A. Then turn on your computer again.
Page 195 Hard Disk Drive and Controller diagnostics check, described in Appendix D. If the diagnostics program indicates an error, contact your Epson dealer. Never open the sealed unit that encloses the hard disk. 6. If you have been using your hard disk for a long time and begin to see numerous read/write errors, the magnetic signals on the disk may be getting weak.
Page 196: Software Problems
7. If you have installed a hard disk drive made by another company in your computer, you need to install MS-DOS. See the MS-DOS Installation Guide for instructions. If the hard disk needs a low-level format, do that before you install MS-DOS.
Page 197 3. If you have tried changing the operating speed using the CPU SPEED switch or the Auto speed function and your copy-protected application program still does not work properly, check the following: Your application program may be having trouble operating while the shadow RAM function is enabled. Run the Setup program on your Reference diskette to disable shadow RAM.

Page 246: Appendix E Physically Formatting A Hard Disk
Appendix E Physically Formatting a Hard Disk This appendix describes how to Sometimes called a low-level format, this procedure should not be confused with the logical format performed by the MS-DOS FORMAT command. The physical formatting of a hard disk is a separate step that is usually done at the factory by the disk manufacturer.
Page 247: Choosing The Type Of Format
In addition to destroying all the data on the hard disk, formatting removes any partitions defined on the disk by SELECT or FDISK and the logical formatting performed by SELECT or FORMAT. After you physically format a new or used hard disk (using option 1 or 2 of the Hard Disk Format Menu), you need to install MS-DOS.
Page 248: Reformatting A Used Disk
The formatting options work as follows: Format first scans the disk (if it has no defective track table) for defective (bad) tracks and lets you decide which tracks to mark as bad. Then the program formats the disk and marks those bad tracks so they are never used to store data.
Page 249: Formatting A New Disk
Many hard disk drives come with a printed list of bad tracks but without the bad tracks flagged on the disk. Other hard disks (such as those supplied by Epson) come with the bad tracks already flagged. If you are formatting a new hard disk that has never been formatted, select the l-Format option to format the disk.
Page 250: Option 1, Format
Option 1, Format If you select l-Format from the Hard Disk Format Menu, you see the following (for a disk that does not have a defective track table): Format Hard Disk Scan hard disk to get defective track information (If the disk already h as a defective track table, you do not see the message because the disk does not need to be scanned for bad tracks.) Select Y to scan the disk or N to skip the scanning process.
Page 251 Next you see this prompt: Accept recommended skewed sectors per head in format : 0 ? (Y/N) For an Epson hard disk drive, accept the recommended value of 0. For another type of drive, use the value recommended in the documentation for the drive.
Page 252: Modifying The Defective Track Table
The program now allows you to edit the table of defective tracks: At the bottom of the table is this prompt: Modify defective track table ? (Y/N) Select N to leave the table as it is. Then skip the following section and go on to “Formatting the Disk,”...
Page 253 2. Type the number of the cylinder containing the bad track and press Enter. You see this prompt: Enter head number (0 - nn ): 3. Type the head number for the bad track and press Enter. To cancel the operation, press Enter without typing a value. When you complete a valid entry, it appears in the table and you can add the next bad track, if necessary.
Page 254: Formatting The Disk
Formatting the Disk When you are ready to start formatting the disk, you see the following warning: WARNING? ALL PARTITIONS OF HARD DISK, NOT JUST IN MS-DOS PARTITION! Do you want to start formatting ? (Y/N) If you are not sure you want to format the hard disk, select N. If you are sure, select Y;...
Page 255: Option 2, Destructive Surface Analysis
You see the head and cylinder numbers decrease as the program progresses. When formatting is complete, the program flags any bad tracks and you see a series of messages like these: Format finished. Flagging bad tracks... Cylinder is nnnn, head is Format completed.
Page 256 To start this test, select 2-Destructive surface analysis from the Hard Disk Format Menu. You see these messages: Analyze Hard Disk Read/Save/Write/Read/Restore/Read check for all tracks... Current cylinder is As the program checks each track, it counts the cylinder numbers (nnnn) down to zero. When the test is complete, the program displays a report on the status of the disk, including a table of unflagged tracks that produced write, read errors-such as the following:...
Page 257: Option 3, Non-Destructive Surface Analysis
To flag the error tracks as bad, select Y. You see a list of the tracks as they are flagged and 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. Option 3, Non-destructive Surface Analysis The Non-destructive surface analysis does not destroy any data, and you can use it to safely check the condition of your hard...
Page 258: Exiting The Hard Disk Format Menu
If the program finds errors, the screen displays a table of the tracks that gave errors, similar to the one the Destructive surface analysis displays. After the status reports, you see this message: Press ENTER to return to the menu. Check the information displayed.
