Chapter 1 SETTING UP YOUR SYSTEM Setting up your Epson Equity 386 personal computer is easy. Just follow the 10 steps in this chapter, which describe how to set up your computer, start MS-DOS, and make copies of your system diskettes.
You’ll also find a registration card with the computer. Fill this card out now and mail it to Epson. With your registration card on file, Epson can send you update information. Be sure to keep your packing materials. They provide the best protection for your computer if you need to transport it later.
(If you have a second diskette drive, be sure to remove the card from that drive too.) Save the protector card and reinsert it whenever you move the computer. If you don’t plan to use your computer for a week or more, reinsert the card to help prevent dust from entering the disk drive.
Moderate environmental conditions. Protect your computer from extremes in temperature, humidity, dust, and smoke. Avoid direct sunlight or any other source of heat. High humidity also hinders operation, so select a cool, dry area. Appropriate power sources. To prevent static charges, connect all your equipment to 3-prong, 120-volt grounded outlets.
Monitor/video card compatibility Video card Monitor Monochrome, graphics, Monochrome or enhanced graphics Graphics, color graphics, Color or or enhanced graphics or enhanced color VGA monochrome Video graphics array Place your monitor on top of or near the computer. It is easiest connect the monitor cable if the backs of the monitor and the computer are facing you.
The Equity 386 has a parallel interface and a serial interface. You can easily connect a printer or other device that has either type of interface-just follow the instructions below. Epson, of course, offers a full range of printers; check with your dealer for more information.
To connect a printer to the computer, you need an IBM-compatible printer cable. If you are not sure which one you need, check with your Epson dealer. Once you have the correct printer cable, follow these steps to connect your printer to the parallel interface on the computer: Place the printer next to your computer.
Connect the other end of the cable to the printer as shown below. To secure the cable, squeeze the clips at each side of the printer port and push them into place. Plug the printer’s power cord into an electrical outlet. Using the Serial Interface If you have a printer, modem, mouse, or any other peripheral with a serial interface, you can connect it to the serial (RS-232C) port on the...
The Equity 386 uses a DB-9P male connector, so be sure you have a compatible cable (or an adapting cable that converts the 9-pin output to the standard 25-pin output). To connect a serial device, follow the same steps as above for connecting a parallel device. You need to ensure that the serial port is set up so it functions properly.
Connecting the Keyboard Follow these steps to connect the keyboard: Turn the computer around so you are facing the front. 2. Pull open the cover on the lower left corner of the computer’s front panel. You need to push down slightly on the tab as you open the cover.
Push the cable into the notch at the left side of the computer, as shown below, so the cable leads away to the side of the computer. Close the keyboard cable cover. You can change the angle of the keyboard by adjusting the legs on the bottom.
If there is a hardware problem you cannot solve after reading the section in Appendix A on troubleshooting, check with your Epson dealer. Always turn off the power, disconnect the computer’s power cord, and wait five seconds before you remove the computer’s cover.
Never turn off or reset your computer while a disk drive light is on. This can destroy data stored on disk or make a whole disk unusable. 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.
(For more instructions on inserting, removing, and caring for diskettes, see Chapter 4.) You can turn on your computer with or without the MS-DOS Startup diskette in the drive. With the Startup diskette in the top drive (A) as it is now, the computer loads MS-DOS from that drive.
This means the operating system is ready for you to enter a command. The command prompt identifies the current operating drive: A, B, or C, for example. Usually, drive A is the top diskette drive; B is the second diskette drive, C is the first hard disk drive, and D is used for a second hard disk drive.
Type the following and press DISKCOPY A: A: You see these messages: Insert SOURCE diskette in drive A: Press any key when ready . . . Drive A (the top drive) already contains a diskette you want to copy (the source diskette), so just press any key. The DISKCOPY program copies the contents of the Operating 1 diskette to the computer’s memory, and then you see the following: Insert TARGET diskette in drive A:...
Chapter 2 Running the Setup Program The first time you use your Equity 386 after setting it up, you need to run the Setup program on the Reference diskette to define the computer’s configuration. This is a simple procedure you must do at least once.
Starting the Setup Program Follow these steps to start the Setup program: Insert the working copy of your Reference diskette into the diskette drive. Press the RESET (See Chapter 4 for more information about resetting the computer.) After the computer performs its self test, it loads the setup and diagnostics programs automatically from the diskette and displays this menu: OPERATIONMENU...
Press 1 and then Enter displays the main Setup menu: E x i t Memory D i s p l a y Auto speed Shadow RAM Coprocessor Mass storage Real-time clock Use 4 and t to move the cursor block through the options on this menu.
Follow these steps to set the amount of memory: Press 1 to highlight the smaller box appears beneath the main Setup menu: If the displayed settings are correct, press t to return to the main menu. change the Main memory setting press changes to 256 KB.
Setting the Display Type Follow the steps below to set the type of display adapter you are using with your Equity 386. Note that with this option you are selecting the type of display adapter (the video card) you are using-not the type of monitor, which may be called something different.
Highlight **SAVE SETTINGS ** and press Setting the Auto Speed Function The Equity 386 can operate at 20 MHz or 8 MHz and you can select either speed using the switch on the front panel of the computer. (See “Selecting Execution Speed” in Chapter 4.) You’ll probably use the faster speed for almost all your operations.
If you are using a copy-protected program that can run only on a diskette or that requires a key disk, try to start the program at 20 MHz. If this works, you do not need to enable the Auto speed function. If you can’t load the program at 20 MHz, enable Auto speed.
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, the Equity 386 automatically copies the data stored in ROM to RAM whenever you turn on or reset the computer.
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 changes back to enabled Setting the Coprocessor Function...
If the settings displayed match the configuration of disk drives in your computer, press t to return to the main menu. If one of the settings is incorrect, change it as described in the following steps. To change the value for one of the diskette drives-drive example-highlight Drive B appears:...
Setting the Real-time Clock The real-time clock in your computer keeps track of the time and date at all times-even when the computer is turned off. Use the Real-time clock option to set the time and date for your computer the first time you run the Setup program.
If you enter an invalid time-for example, a number greater than 23 for the hours or greater than 59 for the minutes or seconds- the computer beeps and ignores your entry. Try again. When the time is correct, press To set the date, highlight Date and press box: Enter the date in the exact format shown in the box, using two digits for the month and day and four digits for the year;...
Leaving the Setup Menu When you finish setting the options in the Setup menu, highlight the and press Exit option Memory size Display type Coprocessor Mass storage There is a second screen of information you need to check. To display that screen, press PgDn.
Check each list to see if all the information is correct. If any setting is incorrect, highlight Change settings Setup menu appears and you can change the setting. If you did not make any changes or you want to cancel the changes you made, highlight Exit without saving and press Operation menu appears on the screen.
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 extended partition as one or more logical drives...
Checking the Hard Disk Your Epson dealer may have already partitioned your hard disk and formatted it so it automatically loads MS-DOS when you turn it on. If this is the case, you do not need to run FDISK or SELECT...
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 press to start MS-DOS. Press twice to accept the date and time prompts. Then Enter type FDISK and press Display Partition Information option.
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 or more logical drives.
Creating the Primary Partition Follow the steps below to create a primary partition on your hard disk: Insert the working copy of the MS-DOS Startup diskette in drive A. Turn on the computer (if it is not on already). At the prompt, type FDISK and press A>...
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.) Insert the working copy of the MS-DOS Startup diskette in drive A (if it is not there already).
Press E twice. The screen displays the following message and prompts: System will now restart Insert DOS diskette in drive A: Press any key when ready . . . Press any key to restart the system (the MS-DOS Startup diskette is already in drive A).
Press to accept the partition size. The screen displays the Enter following message: Extended DOS partition created and shows you information about the partitions you have created. Press 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 defined Total partition size is 657 cylinders.
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. Press twice to accept the date and time shown. Enter The system now recognizes the primary partition as drive C and the extended partition as drives D and E.
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)? Press Y. Formatting does not begin immediately The screen displays the following: WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST!
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: Remove the MS-DOS Startup diskette from drive A and insert the diskette labeled Operating 1 in the drive.
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: Insert the working copy of your MS-DOS Startup diskette in drive A (if it is not there already). At the prompt, type the following and press A>...
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.
Chapter 4 Using the Equity 386 This chapter covers the following basic procedures for using your Equity 386 computer: Locking the computer Selecting execution speed Selecting monitor type Controlling the volume Resetting the computer Using special keys on the keyboard Using disks and disk drives Turning off the computer.
Selecting Execution Speed The Equity 386 can operate at two speeds: 8 MHz or 20 MHz. At 20 MHz, the computer performs all tasks faster, and you will probably use this speed for almost everything you do. Certain application programs, however, have specific timing requirements for diskette access and can run only at the slower speed.
Use the CPU SPEED speed; move it left for 8 MHz or right for 20 MHz. Selecting the Monitor Type When you set up your computer, you used the switch on the front panel to select the type of monitor you are using with your Equity 386: either monochrome or color.
Controlling the Volume Your Equity 386 has a speaker which enables it to beep when you perform certain operations. You can control the speaker’s loudness with the knob on the front panel, shown below. Turn it to VOLUME the right to make the sound louder or to the left to make it quieter. Resetting the Computer You can reset the Equity 386 to load a different operating system or to reload the current operating system.
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: If you are using MS-DOS, hold down key on the numeric keypad at the right of the keyboard.
Key functions Purpose Moves the cursor one tab to the right in normal mode Tab I+- and one tab to the left in shift mode. Caps Lock Changes the letter keys from lower- to uppercase; changes back to lowercase when pressed again. The numeric/symbol keys on the top row of the keyboard are not affected.
Purpose Control cursor location. Home, End Page Up (PgUp) Page Down (PgDn) t +,l+ Changes the function of the numeric/cursor keys from Num Lock numeric to cursor positioning; changes back when pressed again. Cancels the current command line or operation. F1 - F12 Perform special functions within application programs.
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.
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.
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.
Note You must format new diskettes before you can use them with an operating system, Formatting erases all the data an a prepares it to receive- new data; so be sure to format only new blank diskettes or diskettes that contain data you ‘See Chapter 5 for instructions on formatting diskettes.
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.
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).
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.
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.
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. To remove the write protection, slide the switch toward the center of the diskette until it clicks into position so the hole is covered.
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 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.
If you are going to move your computer (even to another part of the room) and you are using a non-Epson hard disk, run the program called HDSIT to prepare the hard disk before moving.
\DOS directory on drive C. Log onto that directory (if necessary) by typing CD \DOS. Or you can just insert the Reference diskette in drive A and type A: to log onto that drive. Then type the following and press Enter: HDSIT 4-20 Using the Equity 386...
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.
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.
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.
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 change the default from A to C, type C : and press acknowledges the change by displaying the command prompt C >. Changing to a new drive is also sometimes called logging onto that drive.
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 diskette as...
If you press when a command line has an error in it, the Enter 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.
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.
A few rules apply when copying files: You must tell MS-DOS where to find the original file and where to store the copy. You cannot create a new file with the same name and in the same directory as an existing file. If an existing file on the destination diskette or directory has the same name as the file you are copying from, the copy automatically replaces the existing file.
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 press COPY A:*.* B:...
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 REN B:*.NEW *.OLD rename all files that begin with the same five characters “MEMOS”...
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.
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 directory structure might look like this: WORDPROC This arrangement would enable you to keep your word processing programs and data files in a directory called WORPROC, your...
Here are some additional points to note about directories: On the root directory, the total number of files and subdirectories must not exceed 512. All directories other than the root directory can have any number of files and subdirectories. Subdirectories are named the same way files are. The name can include as many as eight characters, and you can add an extension of up to three characters.
Here is an example of an absolute pathname: \WORDPROC\PERSONAL 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 backslash, MS-DOS...
This command tells MS-DOS to list on screen (TYPE) the contents of the file JEAN1204.DOC, which is stored in the directory \WORDPROC\PERSONAL. 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 Filenames As mentioned earlier in this chapter, if you want to access a file stored...
Listing the Contents of a Directory To list the files in the current directory, type DIR and press 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 screenful...
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: MKDIR\LEDGER 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 \ LEDGER\ SALES...
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 . . CD \ACCOUNTS Formatting Diskettes Before you can store data on a new diskette, you must format it.
Formatting Diskettes With a Hard Disk 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:...
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 or return to the MS-DOS command prompt by Enter, pressing...
Follow the instructions below for your configuration. Using DISKCOPY with one diskette drive 1. Make sure your original diskette is write-protected. (See Chapter 4 for instructions.) 5-20 Using MS-DOS with Your Equity 386...
If you have a hard disk, make sure you are logged onto the directory that contains the DISKCOPY.COM file. If you don’t have a hard disk, make sure your working copy of the MS-DOS Operating 1 diskette is in drive A. At the MS-DOS command prompt, type the following and press Enter: DISKCOPY A: A:...
When the copy is complete, you see this message: Copy another diskette (Y/N)? Press Y and Enter return to the MS-DOS command prompt. Using DISKCOPY with two diskette drives When you use the DISKCOPY command with two diskette drives, be sure to specify both diskette drives (A: and B:).
See your MS-DOS Reference Manual for complete instructions on using BACKUP Using the Epson HELP Program The Epson HELP program provides online information on MS-DOS commands and utility programs. You can use HELP in either of two ways: You can type HELP at the command prompt and press...
To use the HELP menu, follow these steps: Type HELP at the MS-DOS command prompt and press The screen displays a menu of MS-DOS commands. Use the cursor keys to highlight the command you want information about and press Enter. If there is more than one page of information about the command you selected, you see the prompt PgUp at the top of the screen.
Using the Epson MENU Program Your Equity 386 comes with a program provided by Epson called MENU. With this program you can display a menu of commands and select the one you need. MENU is easy to use because it lets you execute commands without having to remember the exact syntax for each command.
To select an option, use the arrow keys to highlight your selection and then press Most options contain submenus; keep highlighting Enter. your selection and pressing operation. Because MENU works by calling other programs, you may see an error message similar to this when you select an option: SETPRINT.EXE not on the current disk.
MENU program. Using the XTREE Utility Epson has included the XTREE program with MS-DOS to make it easier for you to manage files and run other MS-DOS programs. XTREE is fast and easy to use. It lets you do the work of many MS-DOS commands using a convenient menu format, and provides several features not available elsewhere in MS-DOS.
Display data in both ASCII and hexadecimal format Display how much space is available on your disks. Running XTREE To run XTREE, log onto the directory where XTREE is located or insert the Operating 1 diskette in drive A. Type XTREE at the command prompt and press XTREE reads your disk’s directory, and then the XTREE display appears.
key commands execute additional XTREE commands. Press the key to display the ALT DIR COMMANDS or ALT FILE COMMANDS. These commands appear on the line where the DIR COMMANDS or FILE COMMANDS normally appear. To execute an hold down the key and press the highlighted letter of the command name.
Using an AUTOEXEC.BAT File You may find that there are some commands you want to run every time you turn on your computer. To run a command or a series of commands automatically upon startup, you can type the commands into a special file called AUTOEXEC.BAT When you load MS-DOS, it automatically looks for this file.
Here’s an example of an AUTOEXEC.BAT file: PATH C:\; C:\DOS PROMPT $P The first line tells MS-DOS to look for programs or batch files in the root directory and the DOS directory. This way you can run programs in those directories without having to specify pathnames in the commands.
Using Memory Beyond 640KB Your Equity 386 is equipped with at least 1MB of random access memory. 640KB is for use by the operating system, your application programs, and your data. The memory between 640KB and 1MB is reserved for use by the computer and is not available to application programs or the operating system.
3. Type DEVICE=EEMM386.EXE and press Enter. Press the F6 key, and then press 5. Reboot your computer. This procedure makes the memory in your computer above 1MB available to any application program that supports the Lotus/Intel/ Microsoft Expanded Memory Specification 4.0 (LIM EMS 4.0). About EEMM386.EXE EEMM386.EXE is an expanded memory...
Using HDCACHE and EEMM386.EXE The HDCACHE program (described in your MS-DOS Reference Manual) cannot use expanded memory. If you use both HDCACHE and EEMM386.EXE and you want HDCACHE to use extended memory, you must not convert all your extended memory to expanded memory with EEMM386.EXE.
If you want to install a math coprocessor in your computer, ask your authorized Epson dealer to do it for you. Memory modules allow you to increase the amount of memory in your computer without adding a memory card. This chapter briefly describes the type and amount of memory you can use in the Equity 386.
however, add memory according to certain grouping limitations to preserve the 32-bit access capability of the Equity 386. There are basically two restrictions: the total amount of memory and the way the memory is installed. Here are the guidelines: The total amount of memory must be one of the following: 1MB, 2MB, 4MB, 8MB, 10MB, or 16MB.
This leaves either six or seven slots in which you can install option cards. You can buy option cards from authorized Epson dealers as well as other vendors. This section explains how to remove the computer’s cover, install an option card, and then replace the cover.
3. Disconnect the keyboard. If the computer is locked, unlock it (using the key lock). Otherwise you cannot take off the cover. (See Chapter 4 for instructions on locking and unlocking the computer.) If the monitor is on top of the computer, lift it off and set it to one side.
When the back edge of the cover has cleared the power switch, you can lift off the cover. Separate the sides from the bottom ledge of the computer by pulling them outward slightly, as shown below. Then lift off the cover and set it aside. Installing Options 6-5...
Installing an Option Card The illustration below shows the nine option slots inside the Equity 386. (Slot number 9 is occupied by the SPF card.) Slots 1, 2, and 9 are designed for 8-bit option cards, and slots 3 through 8 are designed for 16-bit cards. As you can see below, a 16-bit card has a second connector.
Usually, it does not matter which slot an option card occupies as long as the card fits in the slot. For example, you can place some &bit cards in a 16-bit slot. However, it is best to leave the SPF card in slot 9 because of the cables.
Keep the screw to secure the option card to the computer. Store the slot cover in a safe place in case you remove the option card later. Unpack the option card and adjust any switches or jumpers on it if necessary. (Check the option card instructions to see if this is necessary.) When you handle the card, be careful not to touch any of the contacts on the circuit board, especially the gold-edged connector pins.
If the card does not go in smoothly, do not force it-pull it all the way out and try again, keeping it straight as you insert it. Secure the end of the card to the back of the computer with the retaining screw.
See “Post-installation Setup,” below, to see if you need to make any configuration changes. Changing Jumpers on the SPF Card If you installed an additional parallel or serial port, you may need to change the jumper settings on the SPF card.

Appendix D Physically Formatting a Hard Disk This appendix describes how to physically format a hard disk. This operation, sometimes called low-level or hard formatting, should not be confused with the logical formatting process performed by the MS-DOS FORMAT command. The physical formatting of a hard disk is a separate step that is usually performed by the disk manufacturer.
Formatting and Checking Options To perform a physical format or to determine if a hard disk needs to be physically reformatted, follow these steps: Insert the Reference diskette in drive A. Turn on or reset the computer. The OPERATION MENU appears.
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. In all cases, run the Non-destructive surface analysis before formatting the disk; this routine finds all bad tracks that are not flagged.
When the scan is complete, the program displays information about the condition of the disk. For a hard disk with no bad tracks, the display looks like this: Scanning finished. Count of tracks flagged bad Count of tracks with other errors Count of good tracks The program then displays a warning about the consequences of proceeding with 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 yy Format completed. Press ENTER to return to the menu. Flagged tracks are identified by xxxx and yy. At this point, press to return to the HARD DISK FORMAT MENU.
Unconditional Format Use this option to format your hard disk when you want to enter the list of bad tracks before formatting begins. The main difference between unconditional and conditional formatting is the way in which bad tracks are identified. With the unconditional format, you must enter the list of bad tracks before formatting begins.
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. add a bad track, follow these steps: Press You see this prompt: Enter cylinder number (1 - xxxx): Type the number of the cylinder containing the bad track you want to enter, and press...
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. This test operates by a complex process of writing, reading, and verifying information on every track of the hard disk, except for tracks that are already flagged as bad tracks.
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: -=====---_=_---------------- Cylinder Head Cylinder Head Confirm to register the tracks in the Write, Read Error Track Table as bad tracks.
When the analysis is complete, the program displays a summary of the status of the disk. This summary lists these counts: Flagged bad tracks Tracks with read, verify errors Good tracks. If no errors occur, you see this message: read, verify error was detected. If errors are found, the program displays a table of the tracks that gave errors, similar to the one displayed by the destructive analysis.
