Page 74: Deleting A Power-On Password
WARNING Be sure to remember the new power-on password you enter or write it down and keep it in a safe place. If you cannot remember the password you enter now, you will not be able to access your computer the next time you turn it on.
Page 75: Selecting The Operating Speed
Selecting the Operating Speed The Equity 386SX can operate at two speeds: high and low. High speed is 16 MHz and low speed simulates 8 MHz. On high, the computer can access memory faster than on low. You will probably use high speed for almost everything you do. However, certain application programs have specific timing requirements for diskette access and can run only at the slower speed.
Page 76: Special Keys On The Equity 386Sx Keyboard

Page 78: Stopping A Command Or Program
Stopping a Command or Program You may sometimes need to stop a command or program while it is running. Many application programs provide a command you can use to cancel or even undo an operation. If you have entered an MS-DOS command that you want to stop, try one of the following commands: Hold down the Q Hold down the...
Page 79: Using Disks And Disk Drives
WARNING Do not reset the computer to exit a program unless you have to. Some application programs classify and store new data when you exit the program. If you reset the computer without properly exiting the program, you may lose data. To reset the computer, MS-DOS must be either on the hard disk or on a diskette in drive A;...
Page 80: 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 Cl Insert and remove diskettes 0 Write-protect diskettes Make backup copies of your diskettes Use a single diskette drive Ll Use two diskette drives Use a hard disk drive.
Page 81 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 82: 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 83 360KB drive-With this drive, use 5 l/4-inch, double-sided, double-density, 48 TPI (tracks per inch), 360KB diskettes. (You can also use single-sided, 160KB or 180KB diskettes.) These diskettes contain 40 tracks per side, 8 or 9 sectors per track, and hold up to 360KB of information, which is approximately 150 pages of text.
Page 84: Caring For Diskettes And Diskette Drives
5 ‘Ivinch drive/diskette compatibility Drive type Diskette types it can read from and write to 360KB 160KB, 180KB, 320KB, 360KB 1.2MB 160KB, 180KB, 320KB, 360KB, 1.2MB WARNING If you write to a 360KB (or 160KB, 180KB, or 320KB) diskette in a 1.2MB drive, you may nut be able to read it or write to it in a 360KB drive later.
Page 85 Keep diskettes away from dust and dirt. Small particles of dust or dirt can scratch the magnetic surface, destroy data, and ruin the read/write heads in a diskette drive. Never wipe, brush, or try to clean diskettes in any way. Keep diskettes in a moderate environment.
Page 86: Inserting And Removing Diskettes
For a 5 l/4-inch diskette, it is best to write on a label before you attach it to a diskette. If you need to write on a label that is already on a 5 ‘/q-inch diskette, use only a soft-tip pen-not a ballpoint pen or a pencil.
Page 87 If you have a 5 ‘/+inch diskette drive, hold the diskette with the label facing up and the read/write slot leading into the drive. 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.
Page 88: 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 89 Note Some program diskettes, such as your MS-DOS diskettes and your Reference diskette, have no switch so they are permanently write-protected. This protects them from being accidentally erased or altered. It is a good idea to write- protect the backup copies you make of your MS-DOS and Reference diskettes.
Page 90: Making Backup Copies
Making Backup Copies It is important to make copies of all your data and system d i s k e t t e s . M a k e b a c k u p ( o r w o r k i n g ) c o p i e s contain programs, such as the original MS-DOS and Reference diskettes that come with the Equity 386SX, and use only the copies.
Page 91: 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 92: 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 93 Note 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 Shell User’s commands. See your instructions. If your Equity 386SX has a hard disk drive, follow these precautions to protect it from damage and to avoid losing data: Never turn off the computer when the hard disk drive light is on.
Page 94 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 95: 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.

Note Before you turn off the computer, be sure to exit any application program you are using. The screen should display the Shell Start Programs Menu or the MS-DOS command prompt. Then remove your diskettes (if any), turn off the computer, and turn off any peripherals.
Page 100: 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 101: 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 and press B : PROGRAM the file named PROGRAM from drive B but stays logged onto...
Page 102 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 103: 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 104: 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 105: Creating And Managing Files
You can use the Setup program on your Reference also diskette to set the correct time and date, See “Setting the 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.
Page 106 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 107: 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 108 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.

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 112: 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 113 Directories are essential for organizing files on a hard disk, and you might even want to create directories on a 1.44MB 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 114 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 115: 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 116: 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 117: 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 118 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 119: 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 \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 \LEDGER\SALES...

This switch displays a wide-format directory listing, like this: Volume drive 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 122 The screen displays a tree diagram of the subdirectories of the current directory, for example: L E D G E R 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:...
Page 123: 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 124: Using The Format Command
Note You can also format diskettes using the Epson MENU program. These programs are easy to use because they let you select options using commands, See your MS-DOS Shell User’s Guide and “Using the Epson MENU Program,” later in Using the FORMAT Command 1.
Page 125 If necessary, remove the Startup diskette from drive A. Insert the diskette you want to format in drive A and press to start formatting. Enter When the diskette is formatted, you see this message: Format complete Volume label (11 characters, ENTER for none)? At the Volume label...
Page 126: Backing Up Data
Formatting a diskette to 720KE3 If you want to format a diskette to a capacity of 720KB in your 1.44MB diskette drive, you need to use a switch with the FORMAT command. The /F:size switch tells the FORMAT command to format the diskette as the size specified in the command even if the capacity of the diskette drive is different.
Page 127: Using The Diskcopy Command
See your MS-DOS Reference Manual for information on XCOPY. Note The MS-DOS Shell and the Epson MENU program provide easy ways to perform the functions listed above. See your MS-DOS Shell User’s Guide and “Using the Epson MENU Program,” later in this chapter.

Page 143: 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 386SX.
Page 144: Adding Memory Modules
Adding Memory Modules The standard Equity 386SX system comes with 1MB of on- board memory. You can add SIMMs (single inline memory modules) to increase the amount of memory in the computer. With added SIMMs, the total amount of memory in your computer must be one of the following: 2MB, 4MB, 6MB, 8MB, 10MB, 12MB, or 14MB.
Page 145 Two sockets in each bank accept only 256KB SIMMs. These sockets are labelled 7A, 8A, 12A, and 13A. The rest of the sockets accept only 1MB SIMMs. You must fill all of the 256KB SIMM sockets before using any of the 1MB sockets. SIMMs must be distributed evenly between the two banks.

Although you do not start each test, you must still supply the appropriate responses to progress from one test to the next.
Page 216: Sequential Seek Check
You can select the individual tests from the following menu. DISKETTE DRIVE(S) AND CONTROLLER CHECK MENU 1 - Sequential seek check 2 - Random seek check 3 - Write, read check 4 - Disk change check 5 - Run all above checks 0 - Exit Before it performs any checks, the program determines the number of diskette drives installed in your computer.
Page 217: Random Seek Check
Select option 1 from the menu to start this test. The program displays the number of each track it finds. For example, with a 1.44MB diskette, the first message you see is: Current track is The track number counts down from 79 to 0 (39 to 0 for a 360KB diskette).
Page 218: 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 before starting the check.
Page 219: Run All Above Checks
When you run the test for 1.44MB, 1.2MB, or 720KB 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 220: Parallel Port (Printer Interface) Check
Parallel Port (Printer Interface) Check Use this option to test the operation of the primary parallel printer port. To perform the test, you must insert a special loop- back connector into the parallel port so that the computer can check individual pins of the port. Contact your dealer if you need a loop-back connector.
Page 221: Parallel Port (On Video Adapter) 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 222 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. The second test is an echo back check during which the port sends data to itself in a fixed data format, at all the possible baud rates.
Page 223: 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 224 If your printer prints different characters than you see in the illustration, you may need to be careful with certain software. The bit-image data is sent to the printer using a command (ESC K) compatible with Epson and IBM printers. Note Even if the test runs only store many characters in its buffer.
Page 225: Hard Disk Drive(S) And Controller Check
Hard Disk Drive(s) and Controller Check Use this option to test the performance of the hard disk drive(s) installed in your computer. If any errors occur, have your dealer or service center check and service the drive.

Page 233: Appendix D Physically Formatting A Hard Disk
Physically formatting a hard disk erases any data it contains. If you have any data on the disk or you are unsure if formatting is necessary, contact your Epson dealer for assistance. Physically Formatting a Hard Disk...
Page 234: 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 235: 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 236: 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 the disk.
Page 237: 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 238 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 239: 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 to leave the table as it is. Then skip the following section and go on to “Formatting the Disk,” below. To modify the defective track entries, select Modifying the Defective Track Table If you select...
