  • Page 39: Using Diskettes

    Using Diskettes Diskette drives allow you to store data on diskettes and retrieve and use stored data. All Equity Ie systems have at least one 720KB diskette drive; you may also have a hard disk drive or a second diskette drive in your system.

  • Page 40: Caring For Diskettes

    You need to format new diskettes before you can use them with an operating system. Formatting erases all the data on a diskette and prepares it to receive new data, so be sure to format only new blank diskettes or diskettes that contain data you want to erase.

  • Page 41: Inserting And Removing Diskettes

    Inserting and removing diskettes To insert a diskette into a diskette drive, hold it with the label facing up and the arrow on the left side pointing into the computer: Slide the diskette into the drive until it clicks into place.

    Making backup copies Copy all diskettes that contain programs, as you did the master system diskettes that come with the Equity Ie, and use only the copies. Store your original system diskettes in a safe place away from your working diskettes. Copy your data diskettes (or hard disk files) regularly, as often as you update them.

  • Page 43: Using A Single Diskette Drive

    Using a single diskette drive An operating system expects the computer to have at least two physical diskette drives, and it displays prompts and messages accordingly. If your system has only one diskette drive, MS-DOS treats your single drive like two logical drives.

  • Page 44: Caring For The Hard Disk

    Copy your data files regularly (as often as you update them) to keep your backup diskettes up-to-date. Use the Epson MENU utility or the MS-DOS BACKUP command to back up your hard disk files. Use the MENU utility or the MS-DOS DISKCOPY command to make copies of your system and program diskettes.

  • Page 45: Resetting The Computer

    Resetting the Computer You can reset the computer to reload the operating system or to restart a program. You may need to reset the computer if an error occurs and the computer does not respond to anything you type.

  • Page 48: Using Msdos With Your Equity Ie

    Chapter 4 Using MSDOS with Your Equity Ie Your Equity Ie comes with MS-DOS, version 3.3. MS-DOS manages your computer system by doing such things as keeping the computer’s memory organized, controlling the monitor display, accepting keyboard input, and directing external communications. To communicate with the operating system, you use MS-DOS commands.

  • Page 49: Changing The Default Drive

    Changing the Default Drive When you see the A > prompt, you know that MS-DOS is operating from drive A. If you want to run a program or find a file on a different drive, however, you must specify that drive. You can do this either by logging on to that drive or by including the drive identifier (the drive letter followed by a colon) when you type the filename.

  • Page 50: Entering Ms-Dos Commands

    Each MS-DOS command is either internal or external. Internal commands are commands that are built into MS-DOS and can be used at any time once MS-DOS is loaded into memory External commands are stored on your system diskettes as program files. To run an external command, MS-DOS must be able to locate the file from your system diskette or from a directory on the hard disk.

  • Page 51: Using Directories

    create using an application program is stored in a special format. If you use a different application program to read that file, you may encounter problems. Each file must have a unique filename so you can retrieve it when you need to.
  • Page 52 Copying from one directory to another Deleting a directory You may also want to read about XTREE, an Epson utility that lets you perform all these functions plus others. XTREE is very easy to use and is described later in this chapter.

  • Page 53: Listing The Contents Of A Directory

    Listing the contents of a directory To list the files in the current directory, type DIR and press lists the names of the files in the current directory on the current drive. If you are logged on to drive C but want to see a directory of the files on the diskette in drive A, type DIR A: and press There are two special notations that identify the current directory and the next directory.

  • Page 54: Creating Directories

    Note MS-DOS contains some commands that make using pathnames easier. The APPEND command lets you set a search path for data files and executable files. The PATH command lets you specify a search path for commands and program files so you don’t have to type a full path name every time you want to call up an application program or an MS-DOS command.

  • Page 55: Changing Directories

    Changing directories To change directories, type CHDIR (or CD) followed by a backslash and the name of the directory. For example, to change to the LEDGER directory, type the following and press CD \LEDGER The backslash identifies the LEDGER directory as a subdirectory of the root directory.

  • Page 56: Deleting A Directory

    Note You can also copy files using XTREE, MENU, or XCOPY. See the sections later in this chapter on using the XTREE and MENU utilities, and see your MS-DOS manual for more information on the XTREE and XCOPY commands. Deleting a directory If you no longer need a directory, you can remove it with the RMDIR (remove directory) command.

  • Page 57: Formatting Diskettes With A Hard Disk And One Diskette Drive

    Note Resides the method described below, you can also format diskettes using the Epson MENU utility. This program is easy to use because it lets you select operations from a menu. For more information, see the section on the MENU utility later in this chapter.

  • Page 59: Copying Data

    Copying Data It’s very important to keep backup diskettes containing copies of the files you create. You can copy data and program files several ways: You can use the DISKCOPY command to make an exact duplicate of a diskette. You can use the COPY command to copy individual files. You can use the BACKUP command to back up the files on a hard disk or diskette in a compressed format.
  • Page 60 At the A > prompt, type the following and press DISKCOPY A: B: MS-DOS prompts you to insert your diskettes: Insert SOURCE Insert TARGET diskette in drive B: Press any key when ready . . . Insert the diskette you want to copy from (the source) into drive A and the diskette you want to copy to (the target) into drive B.

  • Page 61: Using The Copy Command

    Insert the diskette you want to copy from (the source) in the diskette drive and press any key. DISKCOPY starts to copy the contents of the diskette to the computer’s memory. When the memory is full, the screen displays this message: Insert TARGET diskette in drive A: Press any key when ready .
  • Page 62 A few simple rules apply when copying files: You must tell MS-DOS where to find the source file and where to store the target file. You cannot create a new file with the same name and in the same directory as an existing file. If an existing file on the target diskette or directory has the same name as the file you are copying from, the copy automatically replaces the existing file.

  • Page 63: Using The Backup Command

    For example, to copy all the files on the diskette in drive A to the diskette in drive B, type the following and press C O P Y A : * . * B : To copy all files with names that begin with the four letters MEMO and end with any single character, type the following and press COPY A:MEMO?

    Note Even if you run the test for only a short time, your printer may store many characters in its memory. To stop printing, turn the printer off-line. Hard Disk Drives and Controller Check Use this option to test the performance of the hard disk drive installed in your computer.
  • Page 108 Write, read check This check tests the ability of the hard disk drive to read and write data. The test writes to and reads from each sector of the innermost cylinder of the disk, using each head. Note This test destroys all data on the innermost cylinder of the hard disk drive. This cylinder is reserved for diagnostics, however, and is never used for storage by MS-DOS.

  • Page 109: Run All Above Tests

    The cylinder number counts down to 0. At the end of the test, you see a table showing the results of the test. For example, for a 20MB hard disk with three bad tracks, you see: BAD TRACKS READ ERROR TRACKS GOOD TRACKS Press to return to the menu after viewing the table.

    Parallel Port (on Video Adapter) Check Use this option to test the functions of a parallel port on a video adapter card. To perform the test you must insert a special loop-back connector into the port so that the computer can check the port’s individual pins. This test is identical to the check for the primary parallel port.

    Appendix F Formatting a User-installed Hard Disk This appendix describes how you check and format a hard disk that you are installing in your computer. You can also use this program on a hard disk if you are having serious problems. This program performs a hardware-level format of the hard disk.

  • Page 115: Formatting And Checking Options

    If you are installing a hard disk drive and want to format it using this program, choose option 1, Conditional format (Normal). After formatting, you need to partition and format the hard disk for your operating system(s). Refer to your MS-DOS manual for details on partitioning and formatting your hard disk for MS-DOS.

  • Page 116: Conditional Format (Normal

    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.
  • Page 117 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...
  • Page 118 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.

  • Page 119: Unconditional Format

    If you want to format the disk after receiving this error message, do the following: If the drive is not formatted, run the Unconditional format (option 2) and enter any tracks you know are bad in the Bad Track Table. (See “Unconditional Format”...
  • Page 120 The next screen allows you to enter the list of bad tracks. The empty bad track table looks like this: Bad Track Table Cylinder Head Cylinder Head TABLE EMPTY: A = Add track, F = Finish editing Enter command letter: To add a bad track, follow these steps: Press You see this prompt:...

  • Page 121: Destructive Surface Analysis

    If you make a mistake, move the cursor block to the incorrect track, and press C to alter the track data. Or you can press the table. Change the track data just like you add a track. When you have finished editing, check the entries in the table once more. When you are sure the table is correct, press F.
  • Page 122 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 errors. For a 20MB hard disk with one flagged bad track, you see this display: Analysis finished.

  • Page 123: Non-Destructive Surface Analysis

    Non-destructive Surface Analysis The Nondestructive 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 are detected. To start the test, press 4 and then Analyze Hard Disk Read/Verify check for all tracks...
