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; so if you have [...]

Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use it when you like. The Apex 100 has two 360KB diskette drives and the Apex 10020 has one 360KB diskette drive and one 20MB hard disk. This section explains how disks work and tells you how to do the following: Choose diskettes Car[...]

stored. Double-density diskettes have either 40 or 80 tracks, and high-density diskettes have 80 tracks. The double-density, 360KB diskettes you use in your Apex have 40 tracks. A hard disk consists of two or more platters stacked on top of one another; so it has four or more sides with many more tracks per side than a diskette. A disk is further d[...]

Your computer uses the read/write heads in a disk drive to store and retrieve data on a disk. There is one head above the diskette and one below, so the drive can write to both sides of the diskette. To write to a disk, the computer spins it in the drive to a position where one of the read/write heads can access the diskette through the read/write [...]

If you have an optional 720KB drive, use 3 l/2-inch, double- sided, double-density, 135 TPI, 720KB diskettes with this drive. These diskettes contain 80 tracks per side, 9 sectors per track, and hold up to 720KB of information-approximately 300 pages of text. Note You cannot use 3 1/2-inch diskettes that have been formed for 1.44MB in a 720KB diske[...]

Keep diskettes away from magnetic fields. (Remember that diskettes store information magnetically.) There are many sources of magnetism in your home or office, such as electrical appliances, telephones, and loudspeakers. Do not place diskettes on top of your monitor or near an external disk drive. Never touch a diskette’s magnetic surface. The oi[...]

If you have the Apex 10020, follow these additional precautions to protect your hard disk drive and its data: Never turn off the computer when the hard disk drive light is on. This light indicates that the computer is copying data to or from the hard disk. If you interrupt this process, you can lose data. Never attempt to open the hard disk drive.[...]

If a diskette is in the drive but the latch is up (horizontal) and you enter a command for that drive, the computer cannot tell there is a diskette in the drive and displays an error message such as this: Drive A: not ready Make sure a diskette is inserted into the drive and the door is closed Press any key when ready . . . Close the latch and pres[...]

To remove a 3 1/2-inch diskette, press the release button to release it. When the edge pops out of the drive, pull out the diskette and store it properly. WARNING Never remove a diskette or num off the computer while the drive indicator light is on. You could lose data. Also, be sure to remove all diskettes before you turn off the computer. Write-p[...]

Note Some program diskettes, such as you r MS-DOS diskettes, have no notch so they are permanently write-protected. This protects them from being accidentally erased or altered. On a 3 1/2-inch diskette, the write-protect device is a small switch on the lower right comer on the back, shown below. To write-protect a 3 1/2-inch diskette, slide the sw[...]

Chapter 1 describes how to use DISKCOPY to copy your MS-DOS and Reference diskettes. To make backups of other diskettes, use the DISKCOPY command or the MENU program. See Chapter 3 for more instructions on using DISKCOPY and MENU. If you have the Apex 10020, it is best to put most of the programs and data files you use regularly on the hard disk. [...]

On the Apex 10020, you can load the operating system and application programs from the hard disk, create and store your data there, and use the diskette drive just for copying data to or from diskettes. Note If you have only one diskette drive and no hard disk, you need to use that drive to load the operating system as well as the application prog[...]

MS-DOS lets you keep related files together in directories and subdirectories so they are easier to find and use. See Chapter 3 for instructions on how to use directories. Epson also includes the XTREE utility with MS-DOS. XTREE provides simple menus that allow you to move, create, delete, and rename files and directories. This program is especiall[...]

Preparing the hard disk for moving If you need to move your Apex 10020 to a new location- whether it is across the country or just across the room-there is a program you should run to protect the hard disk before you turn off the computer. The HDSIT program moves the disk drive’s read/write heads to a region on the disk surface that does not con[...]

Chapter 3 Using MS-DOS With Your Computer Your computer comes with version 3.3 of MS-DOS. This operating system manages your computer by organizing the computer’s memory, controlling the monitor display, receiving keyboard input, and accessing data. To communicate with the operating system, you use MS-DOS commands. How much you need to know about[...]

Starting and Exiting MS-DOS Before you can run an MS-DOS application program, MS-DOS must be running in memory. Chapter 1 describes how to load MS-DOS on your computer. If you have the Apex 10020, the computer loads MS-DOS from the hard disk automatically when you turn on the computer. If you do not have a hard disk, you need to insert your workin[...]

Using Drive Designators MS-DOS uses letters to identify the disk drives in your system. If you have one diskette drive, it is known as drive A. If you have two diskette drives, the top one is called drive A and the bottom drive is B. If you have a hard disk drive, MS-DOS identifies it as drive C, even if you have only one diskette drive. The Defaul[...]

Changing the default drive To change the default drive, type the letter of the drive you want to change to, followed by a colon. Then press Enter. For example, to change the default from A to C, type the following and press Enter: C: MS-DOS acknowledges the change by displaying the command prompt C>. Changing to a new drive is also called loggin[...]

To run an external command, MS-DOS must be able to locate the file containing the command’s instructions. If it cannot find the file, MS-DOS gives you an error message. If you have the Apex 10020, all the external files are on your hard disk (drive C) in a directory named DOS; so MS-DOS can find any external command you need. If you have the Ap[...]

The MS-DOS command format consists of the command name, parameters, and delimiters. The command name tells MS-DOS the task you want the computer to perform. Parameters specify details such as what data you want co process and where to locate or store a file. Delimiters are characters such as spaces or commas that separate command names and paramete[...]

You can enter an MS-DOS command whenever you see the MS-DOS command prompt. Type the command name and any necessary parameters and delimiters and then press Enter to execute the command. MS-DOS does not execute your command until you press Enter. You can type command names and parameters in either uppercase or lowercase letters. If you make a mista[...]

Naming Files 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 (which is optional). You can choose a name up to eight characters long. Create a name that identifies the information the file contains. The name can contain any characters or numbers except for [...]

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[...]

To copy the file named REPORT to the same diskette and name the copy FACTS, type the following and press Enter: COPY REPORT FACTS Now you have two files on the default 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. Using[...]

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 copying files: You must tell MS-DOS where to find the original file and where to store the copy; that is, you need to specify the drive (and directory, if necessary) for [...]

You can shorten the RENAME command to REN. To change the name of a file from HAMMERS to WRENCHES, therefore, you can type the following and press Enter: REN HAMMERS WRENCHES You can use wildcards to rename groups of files. For example, to change just the extensions of all files on drive B with the extension .NEW to .OLD, type the following and pres[...]

You can use wildcards to delete groups of files. For example, to delete all files on the diskette in drive A (in the current directory), you could type the following and press Enter: DEL A:*.* Because deleting all files is a serious procedure, MS-DOS prompts you to confirm the command when you use the *.* wildcard combination with the DEL command. [...]

3. Type the name of the device, such as LPT1, and press Enter. MS-DOS prints the file on your printer. See your MS-DOS Reference Manual for more information on the PRINT command. Using Directories You can create many files on a diskette, and a hard disk can store thousands of files. To help you organize this much information, MS-DOS lets you subdiv[...]

As the number of files in your WORDPROC and SPDSHEET directories grows, you can create additional directories subordinate to those two-like this, for example: This structure would let you segregate your business word processing files from your personal word processing files, and your sales spreadsheets from spreadsheet files used for financial proj[...]

The following sections discuss the basics of creating and using directories. Note: The XTREE utility provides a simple way to see and organize your directories. See the description of XTREE later in this chapter. The Default Directory MS-DOS always recognizes one directory as the &fault or current directory, just as it always recognizes one dri[...]

To change from PERSONAL back to WORDPROC, you can use the special symbol . . (two periods) or you can use an absolute pathname. (The . . symbol always designates the parent directory, which is the level above the current directory.) In other words, you can type: CD . . or CD WORDPROC Using Pathnames A pathname tells MS-DOS how to find its way to t[...]

Relative pathnames can tell MS-DOS to move upward in the directory tree as well as downward. The symbol . . (two periods) in a pathname tells MS-DOS to move upward one level in the tree. Thus, if the default directory were WORDPROC (in the above example), the pathname . . DOS would tell MS-DOS to move up one level from WORDPROC (in this case to t[...]

For example, suppose you are logged onto the root directory of drive A, and you want to delete the file JEAN1204.DOC, which is stored in the directory WORDPROC PERSONAL of drive C. Enter the command as follows: DEL C : WORDPROCPERSONALJEAN1204.DOC Note that if you change from one drive to another and then try to access a file on the previous [...]

Note MS-DOS provides several commands that make using pathnames easy: APPEND lets you set a search path for date files and executable files so MS-DOS known where to find them even if you don' specify the drive and directory. PATH lets you specify a search path for commands and programs files; so you don't have to type a full pathname ever[...]

In this case, you do not need to specify the path to the LEDGER directory because it is the default directory. Listing the Contents of a Directory You can use the DIR command to list all the files in a particular directory. For example, to list the files in the current directory, type the following and press Enter: DIR MS-DOS lists the names of the[...]

This switch causes MS-DOS to pause after displaying each screenful of information. To see the next screenful, press any key. Another way to view a long directory listing is to use the /W switch: DIR /W This displays the directory listing in a wide format, as follows: Directory of C:WORDPROCPERSONAL . . . LETTER.713 RESUME BOOKRPRT 5 File(s) 16013[...]

The screen displays a report for every directory on the drive, for example: Path: C:LEDGER Sub-directories:RECEIV PAYABL SALES If you would also like to see a list of all the files in the directories, add the /F switch to the command: TREE /F The screen displays the directory information shown above plus the names of all files in each subdirectory[...]

To delete an empty directory from a disk, use the RMDIR command, or its shorthand equivalent, RD. For example, to remove the directory ACCOUNTS, which is a subdirectory in the LEDGER directory, type the following and press Enter: RD LEDGERACCOUNTS If you are currently in the LEDGER directory, you can enter the command as follows: RD ACCOUNTS Form[...]

Note Besides 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 options from a Menu. For more information, see the section on MENU later in this chapter or see your MS-DOS Reference Manual. Formatting Diskettes on the Apex 100 1. Make sure you are logged ont[...]

The formatted diskette is now ready to store data. See the MS-DOS Reference Manual for information about options you can use with the FORMAT command. Formatting Diskettes on the Apex 10020 1. If necessary, type C : to log onto drive C. 2. When you see the C> prompt, type the following and press Enter: FORMAT A: You see this prompt: Insert new d[...]

Formatting Diskettes With One Diskette Drive (No Hard Disk) If your computer has only one diskette drive and no hard disk, follow this procedure to format a diskette: 1. Insert the working copy of your MS-DOS Startup diskette in drive A. 2. When you see the A> prompt, type the following and press Enter: FORMAT A: You see this prompt: Insert new [...]

Backing Up Data It is 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 COPY or XCOPY command to copy individual files or groups of files. You can use the DISKCOPY command to make an exact duplicate of a diskette. You can use the BACKUP command to bac[...]

If the diskette you are copying to has not been formatted, DISKCOPY formats it automatically before copying the data. The procedure for copying diskettes depends on whether you have one or two diskette drives. Follow the instructions below for your model. Using DISKCOPY with the Apex 100 1. Make sure the diskette you want to copy is write-protected[...]

Using DISKCOPY with the Apex 10020 1. Make sure the diskette you want to copy is write-protected. (See Chapter 2 for instructions.) 2. If necessary, type C : to log onto drive C. 3.

Appendix E Physically Formatting a Hard Disk This appendix describes how to physically format a hard disk. Sometimes called a low-level or hard 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[...]

new disk or reformatting a used disk, after physically formatting it, you need to run FDISK and SELECT to prepare the hard disk for use. Follow the instructions in Appendix F. Formatting and Checking Options To perform a physical format or to determine if a hard disk needs to be physically reformatted, follow these steps: 1. Insert the Reference di[...]

Destructive surface analysis tests a formatted hard disk for bad tracks and updates the bad track table. Because this option writes and reads data on the disk, it destroys all data on any track that produces an error. You cannot run the Destructive surface analysis on a disk that has never been formatted. Non-destructive surface analysis checks a f[...]

Formatting a New Disk Many hard disk drives are supplied with a list of bad tracks but without the bad tracks flagged on the disk. Other hard disks are supplied with the bad tracks already flagged. If you are formatting a new hard disk that may not have been formatted, follow these steps: 1. Run the Conditional format to see if the disk has been fo[...]

Note If you have more than one hard disk drive, you see this prompt: Enter drive letter (C/D) ? Press C or D and then Enter. Conditional Format (Normal) Use this option to format the hard disk. All flagged tracks are marked so that they are never used. To start the Conditional format, press 1 and then Enter. The program starts to scan the disk to f[...]

The program then displays a warning about the consequences of proceeding with formatting: WARNING! ALL DATA WILL BE DESTROYED IN ALL PARTITIONS OF HARD DISK, NOT JUST IN MS-DOS PARTITION! Do you want to start formatting (Y/N)? if there are no tracks with other errors, and you are absolutely sure that you want to format the hard disk, press Y and En[...]

Flagged tracks are identified by xxxx and yy. At this point, press Enter to return to the HARD DISK FORMAT MENU. If there are any tracks with other errors, scanning stops and you see this message: Scanning cancelled. Warning: This drive has an unflagged error(s), or is unformatted. Press ENTER to return to the menu. Press Enter. This may mean that [...]

If you are formatting a disk that has never been formatted, check the list of bad tracks that came with the disk. This list identifies each defect by the head and cylinder number, which are required for the Unconditional format. To start the Unconditional format routine, press 2 and then Enter. You are first given the option to change the interleav[...]

Some of the messages change if the table is full or empty. However, the way that you add a bad track or make a correction is the same. To add a bad track, follow these steps: 1. Press A. You see this prompt: Enter cylinder number (1 - xxxx): 2. Type the number of the cylinder containing the bad track you want to enter, and press Enter. You see this[...]

Destructive Surface Analysis Use this option to accurately locate any bad tracks on a hard disk, and to flag any bad tracks that are not flagged. WARNING If any errors occur during this check, all data on the track that produces the error is destroyed. For this reason, if you think that an unflagged bad track is causing trouble, first run option 4,[...]

If the program finds one bad track that is not flagged, the summary would show one track with a write, read error. The report is then followed by a table like this: To flag the error tracks as bad, press Y and Enter. You then see a list of the tracks as they are flagged and then these messages: Flagging bad tracks... Cylinder is 237, head is 2 Pres[...]

When ‘the analysis is complete, the program displays a summary of the status of the disk. This summary lists the following: Flagged bad tracks Tracks with read, verify errors Good tracks. If no errors occur, you see this message: No read, verify error was detected. If errors are found, the program displays a table of the tracks that gave errors, [...]

Appendix F Preparing a Hard Disk for Use If you have the Apex 10020, your hard disk has already been physically formatted, partitioned, and formatted for MS-DOS; so you should not need to do anything to prepare it for use. However, if you have installed a new hard disk in your computer or you need to repartition or reformat the disk you have been [...]

The hard disk you are using has been producing numerous read/write errors. See Appendix E for instructions on performing a low-level format. If you need to format the disk, be sure to do it before completing the steps in this appendix. WARNING The procedures described in this appendix destroy any data on the hard disk. If your disk contains data, u[...]

Formatting the MS-DOS Partition Once you have created the MS-DOS partition, you must format it for MS-DOS. Use the MS-DOS SELECT command to format the new partition, drive C. SELECT automatically does the following: Formats the partition Labels the partition Copies the MS-DOS system files to the hard disk. After you have done this, MS-DOS boots aut[...]

The screen displays this message and prompt: SELECT is used to install DOS the first time. SELECT erases everything on the specified target and then installs DOS. Do you want to continue (Y/N)? 3. Press Y. Formatting does not begin immediately. The screen displays the following message: WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST![...]

SELECT copies the rest of the files from the Startup diskette to the hard disk. When all the files are copied, the A> prompt reappears. The partition on the hard disk is now formatted. Note The SELECT procedure described above copies all the files from your Startup diskette to a directory it created on drive C named /DOS. This enables you to sta[...]

Note The procedure described above copies all the files on the MS-DOS and Reference diskettes to the /DOS subdirectory on drive C. You may, however, prefer to store some of these commands in other subdirectories. For information of creating subdirectories, see Chapter 3 or see your MS-DOS Reference Manual. The file COMMAND.COM (which is included on[...]
