In addition to these items, you need a compatible monitor to

use with the computer. Be sure to keep your packing materials. They provide the best

protection for your computer if you need to transport it later.

Choosing a location

Before you set up your computer, it is important to choose the right location. Select a spot that provides the following:

A large, sturdy desk or table that can easily support the weight of your system, including all of its components: Make sure the surface is hard and flat. Soft surfaces like beds and carpeted floors can generate static electricity, which may erase data on your disks and damage the computer’s circuitry. Soft surfaces also prevent proper ventilation.

Good air circulation: Air must be able to move freely under the system as well as behind it. Leave several inches

of space around the computer to allow ventilation.

Moderate environmental conditions: Protect your computer

from extremes in temperature, direct sunlight, or any other source of heat. High humidity also hinders operation, so select a cool, dry area. Avoid dust and smoke, which can damage disks and disk drives and cause you to lose valuable data.

Setting Up Your System

Page 19

Appropriate power sources:

prevent static charges, connect all your equipment to three-prong, grounded outlets. You need one outlet for the computer, one for the monitor, and additional outlets for a printer and any other peripherals.

If it has the appropriate power cord, you can plug your monitor into the auxiliary power outlet on the back panel of the computer, reducing the number of wall outlets you need. (The current required by the peripheral must not exceed 1 amp.) If you need more outlets, you may want to buy a power strip-available at any electronics store to provide extra outlets. A power strip with surge suppression is recommended.

No electromagnetic interference: Locate your system away from any electrical device, such as a telephone, that

generates an electromagnetic field.

Connecting a Monitor

The video display monitor is the device used by the computer

to communicate with you. Your software will use the display information, such as prompts, text, graphics (charts and pictures), etc.

Several types of monitors are available as options. A typical video display system provides a high resolution monochrome (green or amber screen) screen display. Your computer can be used with either monochrome, color video monitors, EGA or VGA monitors.

In addition to the display monitor itself, the video system includes a video controller board. This board generates the letters, numbers, and graphics symbols displayed on the monitor screen.

Connectors are provided for the display type that is supported by the board (monochrome, RGB color, high resolution EGA, VGA etc.). Certain boards support more than one type of display, and may provide a switch to select either color or monochrome modes.

Connecting a Printer, Mouse, or Modem

The computer has a parallel interface and two serial interfaces on the back panel, so you can easily connect a printer or other type of device with either type of interface.

For example, you can use the parallel port to connect a parallel printer (most printers have a parallel interface). You can use the serial port to connect a serial printer, a serial mouse, or an external modem.

Follow the steps in this section to connect a printer or other peripheral device to either the parallel or serial interface.

The parallel interface on your computer is Centronics compatible and uses a 25pin connector. To connect a parallel printer to your computer, you need an IBM-compatible printer cable. If you are not sure which one you need, or whether you have the right one, check with the store where you purchased the printer.

Once you have the correct printer cable, follow these steps to

connect the printer to the parallel interface on the computer.

Place the printer next to your computer.

One end of the printer cable has a 25-pin, male connector.

2. Connect this end to the parallel port on the back panel of the computer, as shown below. If the plug has retaining screws, tighten them securely.

Turning On the Computer

Before you turn on your computer, read the following safety rules to avoid accidentally damaging the computer or injuring yourself:

Do not unplug cables from the computer when the power switch is on.

Never turn off or reset your computer while a disk drive light is on. This can destroy data stored on disk or make an entire disk unusable. Similary, never remove a diskette from a diskette drive while the drive light is on.

Always wait at least five seconds after you switch off the power before you switch it on again. Turning the power off and on rapidly can damage the computer’s circuitry.

Do not leave a beverage on top of or next to your system or any of its components. Spilled liquid can damage the circuitry of your equipment.

Do not attempt to dismantle any part of the computer. Only remove the cover to install and remove optional devices.

This means that the computer is not yet set up for the

equipment you have installed and you must run the Setup

program, described in Chapter 2. For now, press the Fl key on

the upper left comer of the keyboard to acknowledge the

message and continue.

If you have a SCSI hard disk drive installed with your system, the SCSI BIOS message may be appeared before the above message.

If you cannot see the screen display clearly, use the controls on

your monitor to adjust the brightness and contrast until

characters on the screen are clear and bright.

The computer then loads MS-DOS, the operating system, from

the hard disk into memory. MS-DOS must be in the computer’s memory before you can run any program, such as a word processing program or a spreadsheet program.

The Command Prompt

After the computer has loaded MS-DOS from the hard disk, you see the MS-DOS command prompt on the screen:

The command prompt tells you that your computer is ready to receive instructions. It also identifies the current operating drive: A or C, for example. The command prompt appears on the screen whenever you load MS-DOS, complete an MS-DOS command, or exit an application.

In your computer, the diskette drive is A and the hard disk is drive C. If you have an optional second diskette drive, MS-DOS identifies it as B.

Page 32

Copying System Diskettes

Now that you have started your system and loaded MS-DOS, it is important that you make copies of your MS-DOS diskettes right away. Use the copies (called working copies) as they are

needed and store the originals in a safe place.

Each of the system diskettes is formatted for 36OKB.

(Formatting prepares a diskette to store data and is described in Chapter 3 and Chapter 5.) To copy them, you need seven 36OKB doubledensity, 5 1/4-inch diskettes.

Note

If you do not have any 36OKB diskettes, you can use

unformatted 1.2MB diskettes. When copying from 36OKB diskettes, the DISKCOPY program formats the 1.2MB diskettes for 36OKB.

Follow these steps:

The C > prompt should be on the screen. If not, type C: and press Enter.

After you have copied the MS-DOS diskettes, be sure to label them carefully so you know which one is which. Write on the labels before you attach them to the diskettes in order to prevent damaging the diskettes. Store the originals in a safe place and use the copies as needed.

Resetting Your Computer

If your computer system should “lock-up”, it may be necessary to reset the computer. Resetting the computer causes the CPU to clear its instruction set and the system memory. This ensures there is no “garbage” left in memory to interfere with new program information.

There are three basic ways to reset your computer. They are:

l-l8

Setting Up Your

System

Page 35

CONTROL-ALT-DEL (Keyboard Reset)

Press the CONTROL key and the ALT key at the same time. While holding these keys down, press the DELETE key, then release all three keys. This will reset your computer without running the full self-test diagnostics.

RESET Switch

Press the RESET button on the front panel. This method works even when the keyboard does not respond to your commands. If this does not correct the problem, try the third method.

The POWER Switch

Turn the main system POWER switch off, wait ten seconds, then turn it back on. The computer will then run the complete self-test diagonistic routine.

Caution! Any time you RESET your computer, the memory will be cleared. This will erase any software programs loaded into the system RAM. You may lose important data or have problems using your software after the system re-boots.

Only REST your system if you are sure that all of your

data has been saved to disk, or there is no other way to escape a “lo&up” condition.

You should now be able to reset your computer if you run into trouble. At this point, you can complete the installation of

your system by running the SETUP program. For detailed

information on the SETUP program, see the following chapter.

The CMOS Setup Program

Introduction

The Setup program keeps a record of the host computer’s system parameters (such as memory amounts, disk drives, video

displays, and peripheral devices). Setup resides in the Read

Only Memory Basic Input/Output System (ROM BIOS) so that

it is available each time the host is turned on. Setup stores the information in the complementary metal oxide semiconductor (CMOS) memory. When the host is turned off, a back-up battery retains system parameters in the CMOS memory.

As soon as the host is turned on, the power-on diagnostics routines check memory, attempt to prepare peripheral devices

for action, and offer you the option of pressing run Setup.

< DEL> to

When to Run Setup

During normal daily operation, you do not have to run Setup when you start your computer.

Under the abnormal conditions, an appropriate message displays, advising you to run the Setup program. These conditions indicate that an error has occurred during the power-on self-tests (POSTS).

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 stop or even cancel (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 Ctrl key and press C

Hold down the Ctrl key and press Break

These methods may also work in your application program. If you cannot stop a particular operation, however, you may need to reset the computer, as described in the previous section.

Caution

It is best not to turn off the computer to stop a program or

command. If you have created new data that you have not yet stored, it will be erased if you turn off the computer. Your computer but the memory area is erased each time you turn off or reset the

How Disks Store Data

The diskette you insert in your computer’s diskette drive is made of flexible plastic, coated with magnetic material. It is enclosed in a square jacket. Your computer stores data on the diskette by recording on the magnetic surface.

Unlike a diskette, a hard disk is rigid and fixed in place. It is sealed in a protective case to keep it free from dust and dirt. A hard disk stores data the same way that a diskette does, but it works faster and has much larger storage capacity.

All disks are divided into data storage compartments by sides, tracks, and sectors. Double-sided diskettes — like the ones you use in your computer — store data on both sides. On your disk there are concentric rings, called tracks, in which a disk can store data. Double-density diskettes (such as 36OKB diskettes) have 40 tracks, and highdensity diskettes (such as 1.2MB or

1.44MB diskettes) have 80 tracks. But 72OKB double density

diskette has 80 tracks.

A hard disk consists of two or more magnetically-coated platters stacked on top of one another, so it has four or more sides with many more tracks than a diskette.

Using

OUY

Computer

3-5

Page 51

A disk is further divided by sectors. To understand what a

sector is, picture the spokes on a bicycle wheel radiating from the center of the wheel to the tire. The space between one

spoke and the next is like a sector on a diskette. (See the figure below.) Each track on a 1.2MB diskette has 15 sectors, and each sector holds 5 12 bytes.

Figure 3-3. Sectors and Tracks

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 slot. The read/write slot on

a diskette exposes the diskette’s magnetic surface so the

read/write head can write on the appropriate area.

Because data is stored magnetically, you can retrieve it, record over it, and erase it — just as you play, record, and erase music on a cassette tape.

Page 52

Types of Diskette Drives

Your computer has at least one 1.2MB diskette drive. With this drive, use 5V+inch, double-sided, highdensity, 96 TPI, 1.2MB diskettes. These diskettes contain 80 tracks per side, 15 sectors

per track, and hold up to 1.2MB of information, which is approximately 500 pages of text. You can also format these diskettes for 36OKB — more information.

In addition, you may have a diskette drive of a different type. The following list describes the types of optional diskette drives you can use in your computer and which diskettes you should use with them:

360KB drive — With this drive, use 5 1/4-inch, double-sided,

doubledensity, 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. (With 8 sectors per track, a diskette holds up to 320KB.)

72OKB drive — With this drive, use 3 1/2-inch, double-sided,

doubledensity, 135 TPI, 720KB diskettes. These diskettes contain 80 tracks per side, 9 sectors per track, and hold up to 720KB of information - approximately 300 pages of text.

see your MS-DOS Reference Manual for

1.44MB drive - With this drive, use 3 1/2-inch, double-sided, highdensity, 135 TPI, 1.44MB diskettes. These diskettes contain 80 tracks per side, 18 sectors per track, and hold up to 1.44MB of information, which is approximately 600 pages of text.

If your computer has more than one type of these drives or if you use diskettes from other computers, you need to be aware of certain incompatibilities between the drives and the diskettes they use.

Using Your Computer

3-7

Page 53

Note You must 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 5 for instructions on formatting diskettes.

Drive and diskette incompatibilities

Because of the size difference, you cannot use 3%inch diskettes in a 51/4-inch drive or vice versa. There are also certain limitations on using diskettes that are the same size as the drive but have different capacities. The following tables summarize the possiblities and limitations.

5 1/4+inch drive/diskette compatibility

3-8

Using

Your Computer

Page 54

Because of these incompatibilities, you should indicate the density and diskette type when you label your diskettes. (Usually this information appears on the manufacturer’s label.)

If you have any combination of the above drives (36OKI3,

1.2MB, 72OKB, or 1.44MB), you can copy files from one drive to another — using the copy or XCOPY command — as long as the correct diskette type is in each drive. You can use these commands to copy files between the hard disk and any type of diskette. You cannot use the DISKCOPY to copy from one drive to another if the two drives are not the same type.

Caring for Diskettes and Diskette Drives

Follow these basic precautions to protect your diskette 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. If you interrupt this process, you can destroy data.

Remove all diskettes before you turn off the computer.

Keep diskettes away from dust and dirt. Small particles of

dust or dirt can scratch the magnetic surface and destroy

data. Dust.can also 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. They work best at normal room temperature and in normal humidity. Do not leave your diskettes sitting in the sun, or in extreme cold or heat.

Keep diskettes away from magnetic fields. (Remember that

diskettes store information magnetically.) There are many

Using Your Computer 3-9

Page 55

sources of magnetism in your home or office, such as electrical appliances, telephones, and loudspeakers.

Do not diskettes on top of your monitor or near an external disk drive.

Never touch a diskette’s magnetic surface. The oils on your

fingertips can damage it. Always hold a diskette by its

protective jacket. If you are using a not slide the metal shutter; this exposes the diskette’s surface.

Do not place anything on top of your diskettes and be sure they do not get bent. A diskette does not rotate properly in the drive if it has been damaged.

Carefully label your diskettes. 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-too many labels can make it difficult to insert the diskette into the drive.

It is best to write on the label before you attach it to the

diskette. If you need to write on a label that is already on a

diskette, use only a soft-tip pen, not a ballpoint pen or a pencil. Always indicate the storage capacity and density type on the label.

diskette, do

Store diskettes in a proper location, such as a diskette container. Do not store diskettes flat or stack them on top of each other. When you are not using them, keep your diskettes in their protective envelopes.

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.

3-10

Using Your Computer

Page 56

Never attempt to open the hard disk drive. The disk itself

is enclosed in a sealed container to protect it from dust.

Inserting and Removing Diskettes

To insert a diskette into the drive, hold it with the label facing up and the read/write slot leading into the drive, as shown below.

Figure 3-4. Inserting a diskette (5’/4”)

Slide the diskette into the slot until it is all the way in. Then turn the drive 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.

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:

Page 58

warning Never remove a diskette or turn 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-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.

To write-protect a 5 1/4 inch diskette, cover the small, rectangular notch (shown below) with an adhesive write-protect tab. Write-protect tabs usually come with new 5 1/2 inch diskettes when you buy them.

Write protect

Figure 3-6. 5 1/4 diskette & write-protect tab

Page 59

Note Some program diskettes, such as your 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 switch toward the edge of the diskette until it clicks into position, exposing a hole in the comer.

Making Back up Copies

It is important to make copies of all your data and system diskettes. Copy all diskettes that contain programs, such as the original MS-DOS diskettes that come with your computer, and use only the copies. Store your original MS-DOS diskettes in a safe place away from your working copies. Backup your data diskettes regularly, whenever you revise them, to keep them up-todate, and store them away from your originals.

Chapter 1 describes how to use DISKCOPY to copy your MS-DOS diskette. For more detailed information to make backups of other diskettes, refer to Chapter 4 “Using MS-DOS with your computer”.

It is best to put most of the programs and data files you use regularly on the hard disk. Keep backup copies of all your program files on diskettes, however, and regularly copy important data files to diskettes as well.

Using a Single Diskette Drive

The operating system expects the computer to have at least two diskette drives, and it displays prompts and messages accordingly. If the computer has only one diskette drive, MS-DOS treats the one drive like two logical drives. This helps you perform operations that normally require two diskette drives.

Usually, MS-DOS drive) as drive A and the second diskette drive as drive B. If you have only one diskette drive, MS-DOS recognizes it as both A and B.

For example, if you give a command to copy from A to B, MS-DOS copies data from the diskette you place in the single

recognizes the first diskette drive (the top

Using Your Computer

Page 61

drive (A) to the computer’s memory. Then MS-DOS

automatically prompts you to insert another diskette in the same drive, which it now identifies as drive B. It copies the

data from memory to the new diskette. When the copying is

complete, MSDOS identifies the drive as drive A again, and

you see a prompt to insert the original diskette into drive A.

You can load the opeating system and application programs from the hard disk, create and store your data there, and use

the diskette drive just for copying data to and from diskettes.

Using a Hard Disk Drive

You can create and revise files on a hard disk just as you can on a diskette. The hard disk, however, provides several

advantages:

The 20MB hard disk can store more data than 16x 1.2MB diskettes and the 40MB hard disk can store twice as much.

Your computer can perform all disk-related operations faster.

You can store all your frequently used programs and data

files on the hard disk, eliminating the inconvenience of

inserting and removing diskettes to access different files.

3- 16

Using Your Computer

Page 62

The added storage capacity makes it easy to move back and forth between different programs and data files. However, because it is so easy to add programs and files to your hard disk, you may find yourself trying to organize hundreds of files.

MS-DOS lets you keep related files together in directories and subdirectories so they are easier to find and use.

Backing up hard disk files

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 program 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-todate.

You can see the more detailed information of backing up hard disk files in Chapter 6.

Preparing the hard disk for moving

Before you move the computer, you need to secure the read/write heads inside the hard disk drive. Securing the read/write heads moves them to a region of the disk surface that does not contain data, and locks them in position. This prevents the disk from being damaged if it is bumped accidentally.

To secure the read/write heads for moving, run the TGSHIP program.

Follow these steps to run TGSHIP:

The TGSHIP command should be run whenever you are going to move the main system unit. This command moves the read/write heads inside the hard disk drive to a “safety zone,” where they won’t accidentally scratch the surface of the drive

Using MS-DOS With Your Computer

Once you have your computer system “up-and-running,” you

may begin to work with MS-DOS.

Virtually all application software available for IBM PC/XT and

PC/AT-compatible computer systems runs “under” MS-DOS. Therefore, in order to use these programs, you need to learn how to use MS-DOS. This chapter will give you a basic understanding of MS-DOS and provide you with the basic

tools you need run application software on your computer system. For more detailed explanation of the MS-DOS operating system, see your MS-DOS USER’S GUIDE.

MS-DOS is an acronym for Microsoft Disk Operating System. The disk operating system is a collection of programs that allow you to control all the elements of your computer. When booting up, the MS-DOS command file is copied from the MSDOS main disk into your computer’s memory. From there, it

controls the rest of the system.

During a normal operating session, you will want your computer system to boot up in MS-DOS. Before that can happen, however, you may need to install MS-DOS on your system.

If your system does not have a hard disk system, you must perform the installation routine to configure MS-DOS for floppy disk-based operation.

If you do have a hard disk drive, but MS-DOS has not been

installed you must perform the installation routine to configure MS-DOS for use on the hard disk system.

For complete instructions on installing MS-DOS, see your MS-DOS User’s manual.

Disk Drive Letters

The various disk drives on your computer are assigned letters. As you work with MS-DOS, you will see that these letters are used to identify which drive is to be used at any given time.

The microcomputer industry has standardized the use of letter identification for MS-DOS-type machines as follows:

The first floppy disk drive is referred to as the “A:” drive.

The second floppy disk drive is referred to as the “B:” drive.

The first hard disk drive is referred to as the “C:” drive.

These are called internal commands and can be used anytime

after the system has loaded MS-DOS’ into memory. They do

not require the MS-DOS main system diskette to function.

More complex DOS commands are actually separate programs that provide powerful features for your computer. These are called external commands, and perform such tasks as

This feature is intended to allow owners of single drive systems to use application software designed for dual drive systems.

Copying Your MS-DOS Diskettes

The first important task you must complete with your new

system is to make a “backup” copy of your MS-DOS diskettes. To do this, you will need seven blank diskettes. If is a good idea to prepare seven diskette labels at this time. Write the following on those diskette labels, using a felt tipped pen:

Write down the MS-DOS version number on each diskette label. This will avoid confusion later if you upgrade your

operating system to a new version. As you finish copying and checking each MS-DOS master diskette, peel the correct label off of the backing paper and place it on the upper left-hand side of the front face of the new diskette.

The following procedures will show you how to make backup copies of your MS-DOS master diskettes on both single and dualdrive systems.

Copying on Single Drive Systems

MS-DOS uses the external command DISKCOPY to copy entire diskettes. DISKCOMP is used to compare the original and backup diskettes to ensure that the copy is accurate.

Copying on Dual Drive Systems

To make backup copies of your MS-DOS diskettes on a dualdrive

system, follow the instructions below:

First, rum your computer on and boot up MS-DOS. Choose the Command Prompt option from the DOS shell menu. The system prompt will appear. Enter the following command:

This command indicates to MS-DOS that you want to copy the contents of a diskette in the A drive to a new diskette located in the B drive.

The following message will be displayed:

The “SOURCE” diskette is the disk that you will be copying from. The “TARGET” diskette is the one you will be copying to. Put your master MS-DOS diskette in the A drive, and a new, blank diskette in the B drive.

Close both drive doors. Press any key, such as the SPACEBAR. The A drive will be activated, and your computer will display:

After you have confirmed that the backup diskette is a good copy of the master MS-DOS diskette, you may put your master diskette away in a safe place and put the label on the backup diskette. From now on, only use the master MS-DOS diskette to make copies. For all other purposes, use the backup copy of the MS-DOS diskette. By using the backup copy for everyday computing, and saving the master diskette, you ensure that any accidental erasures can be replaced.

From now on, when this manual refers to the “main system diskettes,” use the backup MS-DOS diskette.

FILES

In the same way that you can keep information grouped together in manila folders, MS-DOS organizes data into files.

While you may store these folders in a cabinet, your computer

stores these files on disks. Separating information into files allows you to work with that information more efficiently.

File Types

There are two basic file types:

Program files

Data files

Using MS-DOS With Your Computer

4-19

Page 83

Program files are files that perform a task. They manipulate the computer and data files in order to achieve a result. MS-DOS is a collection of program files, as are the control programs found in application software.

Data files are files that contain the information (data) used by program files. A file containing a list of names and addresses would be a data file.

The two types of files are closely related. Program files usually create data files. These may be the documents created by a

word processor, the numerical array created by a spreadsheet, or

some other collection of information.

A data file containing a written report can’t do anything by itself. On the other hand, a word processor is useless without

documents to work on.

Filenames and Extensions

Needless to say, each file on a disk must be uniquely

identifiable. To achieve this, MS-DOS requires that you name every file you create, as you create it.

In order to be able to manipulate files easily, MS-DOS has certain rules that you must follow when naming files. As you will see, these rules leave you a great deal of freedom in your selection of filenames.

Each filename can be up to eight characters long. To this eight character name can be added an “extension.” Extensions always begin with a period ( . ) which is followed by up to three characters.

The format for a valid MS-DOS filename is:

ABCDEFGH.JKL

4-20

Using MS-DOS With

Page 84

Most of the characters and symbols on your keyboard are available for use in filenames. These are:

The letters A through Z

The numbers 0 through 9

The following symbols:

The following are examples of allowable filenames:

JANUARY

CHAPTER.001

MEMO.APR

MAYSALES.%&$

$$SALES.OCT

Using MS-DOS With Your Computer

4-21

Page 85

These filenames are valid because none of them are too long, and only legal characters have been used. The following are examples of illegal filenames, along with an explanation:

3RDQUARTER.SALES

This is too long. MS-DOS will accept this filename, but it

will be shortened to fit the size limits. The altered filename would read 3RDQUART.SAL. As you can see, both the filename and its extension have been shortened to the legal length.

CHAPTER/4

The slash ( / ) is an illegal filename character. MS-DOS

will reject the filename and ask for another.

NEW EMPL.LTR

This would be rejected by MS-DOS because of the space in

the filename.

Certain filename extensions have been set aside so that MS-DOS can recognize program files. These are:

COM

EXE

BAT

(for COMMAND file)

(for EXECUTABLE file)

(for BATCH file)

Program files should always have one of these three filename extensions. Data files should never use these reserved extensions. They can, however, use any other extension.

Filename extensions are optional with data files, so you can leave them off entirely, if you want. Using filename extensions with data files allows you to have many different variations for

a set of filenames. For instance, different chapters of a book might be named:

4-22 Using MS-DOS With Your Computer

Page 86

CHAPTER.001

CHAPTER.002

CHAPTER.003

and so on.

Like MS-DOS commands, filenames and extensions can be entered in either upper or lower case, but are always displayed on the screen in upper case. However, since MS-DOS converts lower case filenames into upper case, it is possible to inadvertently erase an existing file by saving a new file with a lower case name. To be safe, always make sure that you have given a unique name to each file on a disk.

Disk Directories

MS-DOS keeps track of the files stored on your disks by maintaining a “directory” on each disk. These directories are listings of the filenames and extensions, along with certain information about the files themselves, such as when the file was created or updated last.

The DIR Command

MS-DOS provides a simple command that allows you to look at the directory of any particular disk. This is the DIR

command. Enter the command as follows:

Using MS-DOS With Your Computer

4-23

Page 87

Some of the names and symbols may be different, but the screen should show these five columns, and a similar last line.

The information presented by the DIR command is as follows:

The filename & extension

The file size (in bytes)

The date the file was created or last updated

The time the file was created or last updated

The number of files listed in the directory

The number of unused bytes of space remaining on the disk

File Searches

You can also use the DIR command to search for specific files on a disk. To do this, enter the DIR command in the following format:

For instance, if you want to find the directory entry for a file

named “MAYSALE!S.RPT” on the diskette in drive A, enter

the command:

Multiple Disk Drive Systems

The DIR command can be used to read the directories of other drives in your system, if any are installed. For instance, to read the directory of the B drive, when you are logged onto drive A, enter the command:

The computer will display the directory of the diskette inserted

in the B drive. A similar command:

will cause the computer to display the directory of your hard disk.

Note that in both examples, the A drive remains the default drive. To change the default drive from A to B, and then display a directory listing, enter the command series:

The computer will display the B drive diskette’s directory, then remain logged to the B drive.

Wildcards

Quite often, when dealing with disk files, you may find yourself looking through directories for a particular file or group of files. MS-DOS has a way to help you sort out those files’ you want without having to read through the entire directory listing. This is through the use of “wildcard” characters. Wildcard characters are used to make a single command cover a number of similarly named files.

While MS-DOS provides several wildcard characters, the one you will be using most often is the asterisk ( * ). The asterisk matches any number of sequential characters in a filename or extension.

For instance, to look at a listing of all the .EXE program files on your main system diskette, enter the command:

Application Software

Now that you know how to make backup copies of your diskettes and how to work with MS-DOS, you can proceed to use application software. Most software packages come with detailed instructions for their set-up and use. These instructions will often ask you to use the information in this chapter to find specific files in the disk directories, or back up the master diskettes provided with each package. Most software packages can be backed up simply by using the MS-DOS DISKCOPY command, as described previously.

Using Floppy Disks

Description

Your computer works with a large electronic memory array called RAM. This stands for Random Access Memory. Your system’s RAM is actually an array of electronic circuits. As

long as the computer is powered up, this circuit array will

“remember” whatever is placed in it. When you turn the power off, however, these circuits will “forget.” Therefore, you need some way of retaining your programs and data after you turn the system off. The most usual way of storing data, at least on DOS-based computer systems, is on floppy disks.

Virtually all commercially available programs are distributed on floppy diskettes: Before you buy an application software package for your computer, you should make sure that it will run under MS-DOS. Products labeled “for IBM PC,” “for IBM PC/AT,” “PC-compatible,” or “MS-DOS-compatible” should run properly. Products intended for other types of computer operating systems, such as CP/M or Apple, will not run on your system.

The most frequent use that you will have for diskettes is to save the data, text, files, etc. that you create. You will use diskettes to store your data between sessions on the computer, as well as to back up your valuable software.

Floppy Disks

Page 93

How Floppy Disks Work

Floppy disks, or diskettes, are made from a flexible plastic that

is coated with a magnetic oxide. The floppy disk drive encodes this oxide with the data generated by the computer. After you turn your system off, unlike electronic RAM, the encoded oxide retains this data. Your data can then be read by the floppy disk drive at a later time.

The magnetic oxide coating on the floppy disk will hold its

encoded data almost indefinitely unless you deliberately erase

it. This is done intentionally when you want to update the

information stored on the diskette.

The plastic disk is safely protected by a thin cardboard jacket. The diskette spins inside this jacket, allowing the entire surface of the diskette to be scanned by the drive’s circuitry. Data is

read from or written onto the diskette through the oval-shaped

slots in the jacket.

Normally, the computer will write new information onto the unused space on the diskette. If there is no unused space, your computer will inform you that the disk is full. You can instruct

the computer to write over the information that is already on the diskette. You might do this to update an inventory file, or change an address and phone number in a database.

Formatting Diskettes

When you get a new carton of diskettes, they are not yet ready to be used. First, they must be prepared to accept data. This is called “formatting” the diskette.

MS-DOS uses the same formatting method regardless of the computer used. This is one of the keys to intermachine compatibility. Since all PC-compatible computers use MS-DOS, they can read all disks created by any other PC-compatible machine.

MS-DOS formats disks with a different “pattern” than

To see what happens when you attempt to use an unformatted disk, insert a new blank diskette into the A drive and close the drive door. Then enter the following command:

The FORMAT Command

MS-DOS provides an external command program called FORMAT.COM, that will format your blank diskettes. When running this program, there are options available that allow you to format several different types of diskette.

The following routines will show you how to use the FORMAT command. These procedures assume that you are formatting double-sided, highdensity, 1.2M-byte diskettes (AT-

compatible). Information on formatting 18OK-byte and 360K-byte diskette will be discussed under the /1 and /4 switch options below.

First, if you have a hard disk installed. MS-DOS on your system, then enter:

The computer will load the FORMAT command file into system memory, then will respond:

Insert the new diskette to be formatted and press the ENTER key.

Formatting a diskette allows you to use it by providing predetermined locations for certain files used by MS-DOS.

Once formatted, the disk directory space is created, as well as

additional areas reserved for use by MS-DOS. One of these areas is the File Allocation Table, or FAT. This part of the diskette contains a list of all of the files on the disk, and where they are physically stored on the diskette.

The other area is the system area. On your MS-DOS main system diskette, this area is occupied by the parts of MS-DOS that are copied into your computer’s memory during the startup routine. During the start-up procedure, the BIOS program, stored on the system motherboard, looks at this part of the diskette to retrieve the active parts of the disk operating system.

If these MS-DOS routines are not present in the system area of a diskette, the BIOS cannot startup the computer. This is what causes the error message:

5-8

Using Floppy Disks

Page 100

If your system does not have a hard disk drive you would normally boot the system up from the MS-DOS system files. The DISKCOPY command copied these files when you created the backup copy of the master diskette.

Sometimes, though, you may want to create a “boot disk” that doesn’t have all of the external DOS commands on it. For instance, you may want to make an “autoboot” copy of an application software diskette.

To format a new diskette while placing the active MS-DOS routines in the system area, enter the following command at the system prompt:

The computer will load the FORMAT command file into system memory, then respond:

Insert a new, blank diskette and press the enter key to start the formatting process. After the new diskette is formatted the

active MS-DOS routines will be copied into its system area. When

the copying is finished the computer will display:

And the following screen will appear if you press ENTER.

enter.)
