(If you are using a compatibility mode provided by the video card, you may need to set the DIP switches on the video card, which will override the display setting in C[...]

When Auto speed is enabled, your computer automatically switches to 8 MHz whenever it needs to access a diskette drive. It runs at 20 MHz for all other operations. There are different types of copy-protected programs, and depending on the type you have, you may or may not want to enable the Auto speed function. Follow these guidelines: l If you are[...]

Setting the Shadow RAM Function A computer can access RAM (random access memory) faster than ROM (read only memory). The Equity 386 provides a shadow RAM feature that enables it to copy data from ROM areas in the computer to the RAM area so it can perform certain operations faster. If you enable the shadow RAM function through the Setup program, th[...]

Now, whenever you turn on or reset your computer, it automatically copies the system ROM BIOS and video ROM to RAM. If you later want to disable either shadow RAM function, follow the same procedure; when you select the option and press Enter, the enabled changes back to disabled. Setting the Coprocessor Function The Setup program assumes you have [...]

Chapter 3 Preparing a Hard Disk for Use If your Equity 386 has a hard disk, follow the instructions in this chapter to prepare the hard disk before using it for the first time. This chapter describes how to do the following: Use the FDISK command to create a primary partition and an extended partition on the hard disk, and then designate the extend[...]

l If you are using MS-DOS and another operating system, use MS-DOS to partition and format the space on the hard disk you want to be used by MS-DOS. Then use the other operating system to prepare the rest of the disk space. For example, if you have a 90MB hard disk and want to use 30MB for MS-DOS and 60MB for XENIX®, use MS-DOS to prepare the firs[...]

2. If MS-DOS does not start, you need to check whether the disk has been partitioned. To do this, place the MS-DOS Startup diskette in drive A and hold down the Ctrl key and Alt key and press Del to start MS-DOS. 3. Press Enter twice to accept the date and time prompts. Then type FDISK and press Enter. Press 4 and Enter to select the Display Partit[...]

Partitioning the Hard Disk Partitioning is necessary because, while your hard disk can store either 40MB or 90MB of data (depending on which Equity 386 model you purchased), MS-DOS cannot manage more than 32MB at a time. The partitioning process divides the single physical disk drive into two or more logical drives. After you have followed the step[...]

Creating the Primary Partition Follow the steps below to create a primary partition on your hard disk: 1. Insert the working copy of the MS-DOS Startup diskette in drive A. 2. 3. 4. Turn on the computer (if it is not on already). At the A> prompt, type FDISK and press Enter. The screen displays the FDISK Options menu. Press 1 to select the Creat[...]

Creating the Extended Partition on a 40MB Disk If you have a 40MB hard disk, follow these steps to create an 8MB extended partition and designate it as drive D. (See the instructions below if you have a 90MB hard disk.) 1. 2. 3. 4. 5. 6. 7. Insert the working copy of the MS-DOS Startup diskette in drive A (if it is not there already). At the A> [...]

8. Press E SC twice. The screen displays the following message and prompts: System will now restart Insert DOS diskette in drive A: Press any key when ready . . . 9. Press any key to restart the system (the MS-DOS Startup diskette is already in drive A). Your computer reloads MS-DOS, displaying the preliminary copyright information and the date pro[...]

5. Press Enter to accept the partition size. The screen displays the following message: Extended DOS partition created and shows you information about the partitions you have created. 6. Press EsC to return to the FDISK Options menu. EDISK automatically displays the Create Logical DOS Drive(s) option and a message similar to this: No logical drives[...]

10. Press any key to restart the system (the MS-DOS Startup diskette is already in drive A). Your computer reloads MS-DOS, displaying the preliminary copyright information and the date prompt. 11. Press Enter twice to accept the date and time shown. The system now recognizes the primary partition as drive C and the extended partition as drives D an[...]

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: WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST! Proceed [...]

Copying the Remaining Files to the Hard Disk Follow the instructions below to copy the files on your other MS-DOS diskettes and the Reference diskette to drive C, the primary partition on the hard disk: 1. Remove the MS-DOS Startup diskette from drive A and insert the diskette labeled Operating 1 in the drive. 2. You should still be logged onto dri[...]

Formatting the Extended Partition Once you have formatted the primary partition and copied the remaining MS-DOS files to the hard disk, follow this procedure to format the extended partition: 1. Insert the working copy of your MS-DOS Startup diskette in drive A (if it is not there already). 2. At the A> prompt, type the following and press Enter[...]

Booting From the Hard Disk Now you can boot your system (load MS-DOS) from drive C on your hard disk. Be sure there is no diskette secured in drive A when you turn on or reset your computer. Otherwise, your computer tries to boot MS-DOS from the disk in drive A. If drive A is empty (or the latch is up), MS-DOS is booted from drive C. Turn off the c[...]

Chapter 4 Using the Equity 386 This chapter covers the following basic procedures for using your Equity 386 computer: l Locking the computer l Selecting execution speed l Selecting monitor type l Controlling the volume l Resetting the computer l Using special keys on the keyboard l Using disks and disk drives l Turning off the computer. Locking the[...]

notch To unlock the computer, insert the key with the notch pointing right and turn the key counterclockwise, to the U N LOCK position. You can remove the key in either a locked or unlocked position. Your Equity 386 comes with two keys; store them safely in different locations in case you misplace one. Be sure the computer is unlocked before you tr[...]

You can control the speaker’s loudness with the VOLUME knob on the front panel, shown below. Turn it to the right to make the sound louder or to the left to make it quieter. - POWER - HDD volume control knob Resetting the Computer Yo[...]

To reset the computer, MS-DOS must be either on a diskette in drive A or on the hard disk. There are three ways to reset. Because each is more powerful than the last, try them in the order listed here: 1. If you are using MS-DOS, hold down Ctrl and Alt and press the Del key on the numeric keypad at the right of the keyboard. The screen goes blank f[...]

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. All Equity 386 systems have at least one diskette drive; you may also have a hard disk drive and/or a second diskette drive in your system. This section explains how disks work and tells you how to do the followi[...]

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. (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. To understand what a sec[...]

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. Types of Diskette Drives Your computer has at least one 1.2MB diskette drive. You may also have a second diskette drive, and it may be the same type or it may be different. The following list describes[...]

Note You must format new diskettes before you can use them with an operating system, Formatting erases all the data an 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 incompat[...]

If you have any combination of the above drives (360KB, 1.2MB, 720KB, 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 command to copy fr[...]

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 m[...]

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 disk drive to access the diskette. To remove the diskette, turn the latch up until it is horizontal and the edge of the diskette pops out. Carefully pull ou[...]

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[...]

On a 3½-inch diskette, the write-protect device is a small switch on the lower-right corner on the back, shown below. To write-protect a 3½-inch diskette, slide the switch toward the edge of the diskette until it clicks into position, exposing a hole in the corner. write-protect switch / To remove the write protection, slide the switch toward the[...]

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 5 or see your MS-DOS Reference Manual for more instructions on using DISKCOPY and MENU. If you have a hard disk, it’s best to put most of the programs and data files you[...]

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 programs you are using. First load the operating system; this copies it to the computer’s memory (RAM) so you do not need to leave the system diskette in the drive. Then you can remove that diskette and insert t[...]

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 an[...]

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 wh[...]

You see a screen of information reminding you that the heads will not be unlocked until you reset the computer or turn the power off and on again. Next the program moves the heads and disables the keyboard. You can now turn off the computer and prepare to move it to the new location. Turning Off the Computer Before turning off your computer, save y[...]

Chapter 5 Using MS-DOS with Your Equity 386 Your Equity 386 comes with version 3.3 of MS-DOS. This operating system manages your computer by organizing the computer’s memory, controlling the monitor display, accepting keyboard input, and directing external communications. To communicate with the operating system, you use MS-DOS commands. How much[...]

Drive Designators MS-DOS uses letters to identify the disk drives in your system. If you have one diskette drive, that device is known as drive A. If you have two diskette drives, one is called drive A, the other drive B. If you have one hard disk drive, MS-DOS identifies its primary partition as drive C, even if you have only one diskette drive. I[...]

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 C : and press Enter. MS-DOS acknowledges the change by displaying the command prompt C >. Changing to a new drive is also sometimes called logging [...]

Some commands also have optional switches you can use. A switch is a type of parameter that alters the effects of a command. For example, suppose you want to format a 360KB diskette in your 1.2MB diskette drive. To do this, you need to add a switch to the FORMAT command like this: FORMAT A: /4 Without the /4 switch, FORMAT would try to format the d[...]

If you press Enter when a command line has an error in it, the screen displays an error message. Usually, the command prompt reappears so you can try again. Type the correct command and press Enter. Creating and Managing Files All your data and programs are stored in files. A data file contains information, such as words, numbers, or pictures. A pr[...]

Some application programs add extensions to the files you create. These application programs use the extension to determine whether it is a compatible data file. Avoid using the same extensions as your application programs. Also, do not use uppercase and lowercase letters to distinguish between files. MS-DOS does not recognize the difference and di[...]

A few rules apply when copying files: l You must tell MS-DOS where to find the original file and where to store the copy. 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 destination diskette or directory has the same name as the file you are copying from, the copy automat[...]

An easy way to copy a group of files is by using wildcard characters in the filenames. You can use two wildcard characters: * and ?. The asterisk represents any group of characters and the question mark represents any single character. For example, to copy all the files on the diskette in drive A to the diskette in drive B, type the following and p[...]

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 press Enter: REN B:*.NEW *.OLD To rename all files that begin with the same five characters “MEMOS” but end with one varying character, type the following and press Enter: RE[...]

- Printing Files If you have a printer attached to your computer, you can print files with the PRINT command. Of course, you will probably be printing files with the application programs you use with MS-DOS, but if you need to print a file from the command prompt, follow the steps below. To print a file named STATS.NBA on drive A: 1. Make sure your[...]

Whenever you format a hard disk or a diskette, MS-DOS creates one directory for you. This directory is called the root directory. Any subsequent directories you create are logically subordinate to the root directory; that is, they are subdirectories of the root directory. A simple directory structure might look like this: Root directory WORDPROC SP[...]

Here are some additional points to note about directories: l On the root directory, the total number of files and subdirectories must not exceed 512. l All directories other than the root directory can have any number of files and subdirectories. l Subdirectories are named the same way files are. The name can include as many as eight characters, an[...]

Here is an example of an absolute pathname: WORDPROCPERSONAL The backslash at the beginning of this pathname tells MS-DOS to start its journey at the root directory, proceed down the directory tree to WORDPROC, then continue down the tree to PERSONAL. Here is an example of a relative pathname: SALES Because this pathname does not begin with a bac[...]

This command tells MS-DOS to list on screen (TYPE) the contents of the file JEAN1204.DOC, which is stored in the directory WORDPROCPERSONAL. Note that the filename is connected to the pathname by a backslash character-the same character used to separate the various directories in the pathname itself. Including Drive Letters With Pathnames and Fil[...]

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 the listing is too long to fit on one screen, add the /P switch to the command, like this: DIR /P This switch causes MS-DOS to pause after displaying each scr[...]

Creating Directories The MKDIR command lets you create directories. To create a LEDGER directory under your root directory, for example, type the following and press Enter: MKDIRLEDGER 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 Enter: MD LED[...]

To change from ACCOUNTS back to LEDGER, you can use the special symbol . . or you can use an absolute pathname. (The . . symbol always designates the parent directory.) In other words, you can type: CD . . or CD ACCOUNTS Formatting Diskettes Before you can store data on a new diskette, you must format it. Formatting prepares the diskette so that M[...]

- Formatting Diskettes With a Hard Disk 1. If necessary, log onto drive C. If you are not in the directory where the file FORMAT.COM is stored, change to that directory. 2. When you see the C > prompt, type the following and press Enter: FORMAT A: You see this prompt: Insert new diskette for drive A: and strike ENTER when ready 3. Insert the dis[...]

4. When the diskette is formatted, you see a message similar to this: Format complete 1213952 bytes total disk space 1213952 bytes available on disk Format another (Y/N)? At this point, you can either format another diskette by pressing Y and Enter, or return to the MS-DOS command prompt by pressing N and Enter. Formatting Diskettes With One Disket[...]

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

2. If you have a hard disk, make sure you are logged onto the directory that contains the DISKCOPY.COM file.
