You can select the slower speed to run application programs that have specific timing requirements. WARNING Do not change the execution speed while you are running a program. Always complet[...]

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. This section explains how diskettes work and tells you how to do the following: l Choose diskettes l Care [...]

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. See Chapter 4 for instructions on how to format diskettes. Caring for diskettes To avoid [...]

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 com[...]

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 typ[...]

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 dir[...]

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. The filename consists of two parts: the name and the extension. You can choose a name up to eight characters long.[...]

The structure of a directory may look like this: Root directory (1) I I LEDGER WORDPROC 1 1 ACCdU NTS SALES BUSlklESS PERSpNAL STORIES ROGER The root directory does not have a name, but is always identified by a backslash ( ). You name subdirectories when you create them. A subdirectory name can be up to eight characters long, consisting of lette[...]

Listing the contents of a directory To list the files in the current directory, type DIR and press Enter. MS-DOS 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 Enter. There are two special notations[...]

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[...]

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 Enter: CD LEDGER The backslash identifies the LEDGER directory as a subdirectory of the root directory. Once you are in a directory, you can access any fi[...]

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. To remove a dire[...]

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.

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: l You can use the DISKCOPY command to make an exact duplicate of a diskette. l You can use the COPY command to copy individual files. l You can use the BACKUP command to back up the files on a hard[...]

3. 4. 5. At the A > prompt, type the following and press Enter: DISKCOPY A: B: MS-DOS prompts you to insert your diskettes: Insert SOURCE diskette in drive A: 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[...]

4. 5. 6. 7. 8. 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 . . . Remove the diskette from drive A [...]

A few simple rules apply when copying files: l You must tell MS-DOS where to find the source file and where to store the target file. l You cannot create a new file with the same name and in the same directory as an existing file. l If an existing file on the target diskette or directory has the same name as the file you are copying from, the copy [...]

For example, to copy all the files on the diskette in drive A to the diskette in drive B, type the following and press Enter: COPY 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 Enter: COPY A:MEMO? B: Another task you can perform with the COPY command is to[...]

Make sure you have enough formatted diskettes to back up the data on your hard disk drive. It can take about 25 720KB diskettes to copy a 20MB hard disk drive that is completely full (although it is rare that you would store this many files on a hard disk). Note BACKUP formats unformatted target diskettes if you use the /F switch when you enter the[...]

Serial Port (RS-232C Port) Check Use this option to test the functions of the primary serial communications (RS-232C) port. To perform the test,[...]

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 [...]

Dot-Matrix Printer Check Use this option to check: l The operation of your printer in IBM-compatibility mode l The compatibility of your printer with the extended character set used by the Equity Ie l The ability of your printer to produce dot graphics and print images of the graphics screen. When you select option 14 from the DEVICE LIST, you see [...]

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. If any errors occur, have your dealer check and service the drive. Wh[...]

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 f[...]

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 . . . . . . . . . . . . . . . . . . . 3” GOOD TRACKS . . . . . . . . . . . . . . . . . . .[...]

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. For more details, see[...]

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. Format hard disk is option 2 on the OPERATION MENU. Y[...]

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. If you are reformating a hard[...]

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 unflagged bad tracks without destroying data, use option 4, [...]

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 sc[...]

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 [...]

If you want to format the disk after receiving this error message, do the following: 1. 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” below.) 2. Run the Destructive surface analysis (option 3) to flag any remaining bad tracks. (See[...]

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 Cylinder Head Cylinder Head Cylinder Head TABLE EMPTY: A = Add track, F = Finish editing Enter command letter: To add a bad track, follow these steps: 1. Press A. You see this prompt: Enter cylinder numb[...]

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 D to remove the track from 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. The program displ[...]

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. Count of tracks flagged bad = Count of tracks with write, read errors = ; Count of good tra[...]

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 t[...]
