If you have entered an MS-DOS command that you want to stop, try one of the following commands: Hold down the Hold down the...
Page 74: Using Disks And Disk Drives
To reset the computer, MS-DOS must be either on the hard disk or on a diskette in drive A; so if your computer does not have a hard disk, insert the Startup diskette in drive A. There are three ways to reset. Because each is more powerful than the last, try them in the order listed here: If you are using MS-DOS, hold down key.
Page 75: How Disks Store Data
This section explains how disks work and tells you how to do the following: Use different types of diskettes and diskette drives Care for your diskettes and diskette drives Insert and remove diskettes CI Write-protect diskettes Make backup copies of your diskettes Use a single diskette drive LI Use two diskette drives LI Use a hard disk drive.
Page 76 Because a hard disk consists of two or more platters stacked on top of one another, it has four or more sides with many more tracks per side than a diskette. (The number of tracks depends on the capacity of the hard disk. You do not need to know how many sides and tracks your hard disk has.) A disk is further divided by sectors.
Page 77: Types Of Diskette Drives
Your computer uses the read/write heads in a disk drive to store and retrieve data on a disk. To write to a disk, the computer spins it in the drive to position the area on the disk where the data is to be written under the read/write head. A diskette has an exposed area where the read/write head can access it.
Page 78 720KB drive-With this drive, use 3 ‘/z-inch, double-sided, double-density, 135 TPI, 720KB diskettes. These diskettes contain 80 tracks per side, 9 sectors per track, and hold up to 720KB of information, which is approximately 300 pages of text. 1.44MB drive-With this drive, use 3 i/z-inch, double-sided, high-density, 135 TPI, 1.44MB diskettes.

Page 80: Caring For Diskettes And Diskette Drives
Caring for Diskettes and Diskette Drives Follow these basic precautions to protect your diskettes and avoid losing data: Do not remove a diskette from the diskette drive or turn off the computer while the drive light is on. This light indicates that the computer is copying data to or from a diskette.
Page 81: Inserting And Removing Diskettes
Carefully label your diskettes and be sure to indicate the diskette type and density. Attach labels firmly but gently, and only along the top of a diskette (next to the manufacturer’s label). Do not stick several labels on top of one another;...
Page 82 Slide the diskette into the slot until it is in all the way. Then turn the latch down to lock it in a vertical position. This keeps the diskette in place and enables the read/write heads in the diskette drive to access the diskette. To remove the diskette, turn the latch up until it is horizontal and the edge of the diskette pops out.
Page 83: Write-Protecting Diskettes
WARNING Never remove a diskette or, turn off the computer while the diskette drive light is on. You could lose data. Also, be sure to remove ail diskettes before you turn off the computer. Write-protecting Diskettes You can write-protect a diskette to prevent its data from being altered.
Page 84 N o t e Some program diskettes, such as your MS-DOS diskettes your Reference diskette, have no notch or no switch so they are permanently write-protected. This protects being accidentally erased or altered. On a 3 ‘/z-inch diskette, the write-protect device is a small switch on the back of the diskette in the lower right corner, shown below.
Page 85: Making Backup Copies
Making Backup Copies It is important to make copies of all your data and system diskettes. Make backup (or working) copies of all diskettes that contain programs, such as the original MS-DOS and Reference diskettes that come with the Equity IIe, and use only the copies. Store the original diskettes in a safe place away from your working diskettes.
Page 86: Using A Single Diskette Drive
Using a Single Diskette Drive MS-DOS expects the computer to have at least two diskette drives, and it displays prompts and messages accordingly. If your system has a single diskette drive, MS-DOS treats your one drive like two logical drives. This helps you perform operations that normally require two diskette drives.
Page 87: Using Two Diskette Drives
Using Two Diskette Drives If you have two diskette drives, you can use the top drive (A) for loading the operating system and application programs and the second drive (B) for creating data. If you have a hard disk, you will probably need the diskette drives just to copy files to and from the hard disk and to copy diskettes.
Page 88 The MS-DOS Shell program is a menu-driven program which makes it easy for you to move, create, delete, and rename files and directories, as well as view files and execute MS-DOS commands, See your instructions. If your Equity IIe has a hard disk drive, follow these precautions to protect it from damage and to avoid losing data: LI Never turn off the computer when the hard disk drive light is on.
Page 89 Backing up the hard disk While the hard disk is very reliable, it is essential to back up your hard disk files to diskettes in case you lose some data accidentally. Make copies of all your system and application diskettes before copying the programs to the hard disk. After you create data files on the hard disk, be sure to copy them to diskettes whenever you revise them to keep your backup diskettes up-to-date.
Page 90: Turning Off The Computer
You see a message on the screen that tells you the disk drive’s read/write heads will remain locked until you reset the computer or turn the power off and on again. The computer locks the heads and disables the keyboard. You can now turn off the computer and prepare to move it to the new location.

Page 93: Using Drive Designators
Before you turn off the computer, make sure the screen displays the Shell Start Programs Menu or the MS-DOS command prompt. Then remove your diskettes, turn off the computer, and turn off any peripherals. Using Drive Designators MS-DOS uses letters known as drive designators to identify the disk drives in your computer.
Page 94: 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 95: 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 the file named PROGRAM from drive B but stays logged onto drive A.
Page 96 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 97: 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, delimiters.
Page 98: 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 99: Creating And Managing Files
You can also use the Setup program on your Reference diskette to set Real-time Clock” in Chapter 2 for instructions. 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.
Page 100 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 101: 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 wildcard characters You can copy one or more files and give them new names...
Page 102 To copy the file named REPORT to the same drive or directory and name the copy FACTS, type the following and press 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 103 To copy REPORT, FACTS, and MEMO from drive A to a file named DATA on drive B, type the following and press 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 104: 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 RENAME PROSPECT CLIENT You can shorten the RENAME command to REN.
Page 105: 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 DEL C:REPORT.AUG To delete the file WRENCHES from drive C, type the following and press DEL C:WRENCHES To display a prompt asking you to confirm that you want to...
Page 106: 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 107 While you may not need to create directories on a 360KB diskette-especially if it contains only a few large files- directories are essential for organizing files on a hard disk. Whenever you format a disk, MS-DOS automatically creates one main directory. This directory is called the Any directories you later create are logically subordinate to the root directory;...
Page 108 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 109: The Current Directory
The Current Directory MS-DOS always recognizes one directory as the current (or 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 110: 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 111: 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 112 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 113: Creating Directories
Creating Directories You use the MKDIR command to create directories. For example, to create a LEDGER directory under the root directory of the current drive, type the following and press MKDIR 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 MD \LEDGER\SALES...

This switch displays a wide-format directory listing, like this: Volume in drive C is APPLICANTS 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 116 The screen displays a tree diagram of the subdirectories of the current directory, for example: C:\LEDGER RECEIV PAYABL SALES 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: C:\LEDGER RECEIV...
Page 117: Removing Directories
To see the list of subdirectories of another directory, include the pathname: TREE C:\WORDPROC 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 132: 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 133: 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 134 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: If you are creating an AUTOEXEC.BAT file on your Startup diskette, insert the Startup diskette into drive A and log onto that drive.
Page 135: Using Memory Beyond 640Kb
Using Memory Beyond 640KB The Equity IIe comes with 1MB of random access memory. MS-DOS and your application programs that run under MS-DOS use the first 640KB of memory. You can use the memory between 640KB and 1MB as extended or expanded memory.
Page 136: Using Eemm286.Sys
Press F6 and then 5. Reset the computer. Using EEMM286.SYS EEMM286.SYS is an Epson expanded memory manager that makes the Equity IIe’s expanded memory available or lets you use extended memory to emulate expanded memory, so that you can use application programs that support LIM EMS.
Page 137 The full syntax for the command line that activates EEMM286.SYS is: D E V I C E = [ d : ] [ p a t h ] E E M M 2 8 6 . S Y S [ / K ] [ / P n ] [ / F ] [ / T ] [ / W ] The items in brackets are optional.
Page 138 The following paragraphs describe the options in the table. The d:path parameter specifies the pathname. You specify the pathname if the file EEMM286.SYS is not in the root directory of the hard disk or diskette from which you load MS-DOS. For example, if EEMM286.SYS is in a directory called \DOS on drive C, include the pathname, like this: D E V I C E = C : \ D O S \ E E M M 2 8 6 .
Page 139 The /Pn switch specifies input/output ports the Equity IIe uses. Use this switch only if you experience a conflict with an option card installed in your computer. On the Equity IIe, the input/ output ports EEMM286.SYS uses are 2n8, 12n8, 42n8, 52n8, 82n8, 92n8, C2n8, D2n8.

For example, with a 1.2MB diskette, the first message you see is: Current track is 79 The track number counts down (from 39 or 79) to 0. The seek is performed by each head, so you see the count twice.
Page 211: Disk Change Check
If you have only one diskette drive, you see a prompt to remove the the Reference diskette and insert a blank diskette before running the test. You see these messages: If using drive 1, remove your Reference Disk. Insert a formatted blank disk in the drive starting before Any data present may be erased.
Page 212: Math Coprocessor Check
When you run the test for 1.2MB, 720KB, or 1.44MB drive, you see this prompt: Remove the disk from drive 1. Remove the diskette. The program displays the following prompt: Re-insert the disk into drive 1. Reinsert the diskette. If no errors occur, the menu reappears. An error occurs if you do not remove or replace the diskette in time or if the drive is malfunctioning.
Page 213: Parallel Port (Printer Interface) Check
If the coprocessor is installed, the program runs a series of checks on the precision with which the coprocessor performs calculations and handles exceptions. Parallel Port (Printer Interface) Check Use this option to test the operation of the primary parallel printer port.
Page 214: Parallel Port (On Video Adapter) Check
This test is similar to the Parallel Port Check. For more details, see the description of the Parallel Port (Printer Interface) Check. Parallel Port (on Video Adapter) Check Use this option to test the operation of an additional parallel port on a video adapter. To perform the test, you must insert the special loop-back connector into the parallel port on the video adapter so that the computer can check individual pins of the port.
Page 215 Insert the loop-back connector. Then select check. First, the program checks the serial port control lines to see that they are able to change from high to low and vice versa. No messages are displayed during this part of the test unless an error occurs.
Page 216: Alternate Serial Port Check
Alternate Serial Port Check Use this option to test the functions of an additional serial communications (RS-232C) port. To perform the test you must insert a special loop-back connector into the alternate serial port so that the computer can check individual pins of the port. This test is identical to the check for the primary serial port.

Page 227: 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 228: Reformatting A Used Disk
The formatting options work as follows: first scans the disk (if it has no defective track Format 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 229: 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 option 1, Format, to format the disk.
Page 230: Option 1, Format
Option 1, Format If you select 1 -Format 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...
Page 231 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 232: Modifying The Defective Track Table
The program now allows you to edit the table of defective tracks: Cylinder Cylinder Head Defective Track Table: Modify defective track table ? (Y/N) At the bottom of the table is this prompt: Modify defective track table ? (Y/N) Select to leave the table as it is.
Page 233 Type the number of the cylinder containing the bad track and press Enter. Enter head number (0 - Type the head number for the bad track and press To cancel the operation, press When you complete a valid entry, it appears in the table and you can add the next bad track, if necessary.
