2. To turn on the computer, press the power switch. The power indicator on the front panel lights up. After a few seconds, the computer starts to perform an internal self test. This is a series of checks the computer completes each time you turn it on to make sure everything is working correctly.
Page 33: Loading Ms-Dos On The Apex 100
If you have the Apex 100 (no hard disk), the computer does not load MS-DOS, but instead displays the following: Non-system disk or disk error Insert system diskette in drive A and strike any key when ready These messages tell you that you need to insert the MS-DOS Startup (system) diskette in the top drive, drive A, so the computer can load the operating system.
Page 34 2. When the diskette is in all the way, turn the latch down (clockwise) to lock the diskette in place. (For detailed instructions on inserting diskettes, see Chapter 2.) 3. Press any key. The computer loads MS-DOS into its memory where it will remain until you turn off the computer.
Page 35: The Command Prompt
You need to set the date and time this way only once; the computer’s real-time clock keeps track of the date and time even when the computer is off. The next time you load MS-DOS, you can these prompts to accept the displayed date and time. MS-DOS updates months and years correctly-whether the month has 31, 30, 29, or 28 days—and even accounts for leap years.
Page 36: Setting The Time And Date On The Apex 100\20
If you load MS-DOS from the hard disk, the command prompt looks like this: C:\> The hard disk prompt is different because the Apex been set up with a special command that changes the command prompt to show the current directory. (A directory consists of a group of files stored together under an identifying name.
Page 37 2. If the date is correct, press Enter to leave it unchanged. To change the date, type the appropriate numbers for the month, day, and year, as shown. For example, to set the date for August 30, 1989, type the following and press Enter: 8-30-89 3.
Page 38: Copying System Diskettes
Copying System Diskettes Now that you have set up your system and loaded MS-DOS, it is important that you make copies of your MS-DOS and Reference diskettes right away. Use only the copies (usually called “working copies”) for daily use and store the originals in a safe place.

Chapter 2 Using Your Computer This chapter covers the following basic procedures for using your computer: Changing the operating speed Using special keys on the keyboard Interrupting a command or program Resetting and turning off the computer Using disks and disk drives. Changing the Operating Speed Your computer can operate at two speeds: 4.77 MHz or 10 MHz.
Page 43: Using Special Keys
WARNING You can change the speed while the computer is on, but do not change it while you are running a program. Complete your current operation, exit the program to the MS-DOS command prompt, and then change the speed. Using Special Keys Certain keys on your keyboard serve special functions when your computer is running application programs.

Page 47: Using Disks And Disk Drives
Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use it when you like. The Apex 100 has two 360KB diskette drives and the Apex 100\20 has one 360KB diskette drive and one 20MB hard disk.
Page 48 stored. Double-density diskettes have either 40 or 80 tracks, and high-density diskettes have 80 tracks. The double-density, 360KB diskettes you use in your Apex have 40 tracks. A hard disk consists of two or more platters stacked on top of one another;...
Page 49: Choosing Diskettes
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.
Page 50: Caring For Diskettes And Diskette Drives
If you have an optional 720KB drive, use 3 l/2-inch, double- sided, double-density, 135 TPI, 720KB diskettes with this drive. These diskettes contain 80 tracks per side, 9 sectors per track, and hold up to 720KB of information-approximately 300 pages of text. Note You cannot use 3 1/2-inch diskettes that have been formed for 1.44MB in a 720KB diskette drive.
Page 51 Keep diskettes away from magnetic fields. (Remember that diskettes store information magnetically.) There are many sources of magnetism in your home or office, such as electrical appliances, telephones, and loudspeakers. Do not place diskettes on top of your monitor or near an external disk drive.
Page 52: Inserting And Removing Diskettes
If you have the Apex 100\20, 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.
Page 53 If a diskette is in the drive but the latch is up (horizontal) and you enter a command for that drive, the computer cannot tell there is a diskette in the drive and displays an error message such as this: Drive A: not ready Make sure a diskette is inserted into the drive and the door is closed...
Page 54: Write-Protecting Diskettes
To remove a 3 1/2-inch diskette, press the release button to release it. When the edge pops out of the drive, pull out the diskette and store it properly. WARNING Never remove a diskette or num off the computer while the drive indicator light is on.
Page 55: Making Backup Copies
N o t e Some program diskettes, such as your 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 in the comer.
Page 56: Using A Single Diskette Drive
Chapter 1 describes how to use DISKCOPY to copy your MS-DOS and Reference diskettes. To make backups of other diskettes, use the DISKCOPY command or the MENU program. See Chapter 3 for more instructions on using DISKCOPY and MENU. If you have the Apex 100\20, it is best to put most of the programs and data files you use regularly on the hard disk.
Page 57: Using The Hard Disk Drive
On the Apex 100\20, you can load the operating system and application programs from the hard disk, create and store your data there, and use the diskette drive from diskettes. Note If you have only one diskette drive and no hard disk, you need to use that drive to load the operating system as well as the application programs you are using.
Page 58 See Chapter 3 for instructions on how to use directories. Epson also includes the XTREE utility with MS-DOS. XTREE provides simple menus that allow you to move, create, delete, and rename files and directories. This program is especially useful on the hard disk drive because of the large number of files the disk can hold.
Page 59 Preparing the hard disk for moving If you need to move your Apex 100\20 to a new location- whether it is across the is a program you should run to protect the hard disk before you turn off the computer. The HDSIT program moves the disk drive’s read/write heads to a region on the disk surface that does not contain data, and locks them securely in position.

Page 61: Starting And Exiting Ms-Dos
Starting and Exiting MS-DOS Before you can run an MS-DOS application program, MS-DOS must be running in memory. Chapter 1 describes how to load MS-DOS on your computer. If you have the Apex 100\20, the computer loads MS-DOS from the hard disk automatically when you turn on the computer.
Page 62: Using Drive Designators
Using Drive Designators MS-DOS uses letters to identify the disk drives in your system. If you have one diskette drive, it is known as drive A. If you have two diskette drives, the top one is called drive A and the bottom drive is B.
Page 63: Types Of Ms-Dos Commands
Changing the default drive To change the default drive, type the letter of the drive you want to change to, followed by a colon. Then press Enter. For example, to change the default from A to C, type the following and press Enter: MS-DOS acknowledges the change by displaying the command C>.

Page 66 The MS-DOS command format consists of the command name, parameters, and delimiters. The command name tells MS-DOS the task you want the computer to perform. Parameters specify details such as what data you want co process and where to locate or store a file. Delimiters are characters such as spaces or commas that separate command names and parameters.
Page 67: Creating And Managing Files
You can enter an MS-DOS command whenever you see the MS-DOS command prompt. Type the command name and any necessary parameters and delimiters and then press Enter to execute the command. MS-DOS does not execute your command until you press Enter. You can type command names and parameters in either uppercase or lowercase letters.
Page 68: Naming Files
Naming Files Each file must have a unique filename so you can retrieve it when you need to. The filename consists of two parts: the name and the extension (which is optional). You can choose a name up to eight characters long. Create a name that identifies the information the file contains.
Page 69: Copying Files
Copying Files You can use the COPY command to copy individual files or groups of files. COPY is an internal command; you can use it any time you see the MS-DOS command prompt. You can use the COPY command to copy files in several ways: You can copy individual files from one disk to another You can copy a group of files using wildcard characters You can copy one or more files and give them new names...
Page 70 To copy the file named name the copy FACTS, COPY REPORT FACTS Now you have two files on the default drive that have the same contents but different names. In this example, you can omit the drive designators because the original file and the copy are both on the current drive.
Page 71: Renaming Files
To copy REPORT, FACTS, and MEMO from drive A to a file named DATA on drive B, type the following and press Enter: COPY A:REPORT + A:FACTS + A:MEMO B:DATA Remember these rules when copying files: You must tell MS-DOS where to find the original file and where to store the copy;...
Page 72: Deleting Files
You can shorten the RENAME command to the name of a file from HAMMERS to WRENCHES, therefore, you can type the following and press Enter: REN HAMMERS WRENCHES You can use wildcards to rename groups of files. For example, to change just the extensions of all files on drive B with the extension .NEW to .OLD, type the following and press Enter: REN B:*.NEW *.OLD...
Page 73: Printing Files
You can use wildcards to delete groups of files. For example, to delete all files on the diskette in drive A (in the current directory), you could type the following and press Enter: DEL A:*.* Because deleting all files is a serious procedure, MS-DOS prompts you to confirm the command when you use the *.* wildcard combination with the DEL command.
Page 74: Using Directories
3. Type the name of the device, such as LPT1, and press Enter. MS-DOS prints the file on your printer. See your MS-DOS Reference Manual for more information on the PRINT command. Using Directories You can create many files on a diskette, and a hard disk can store thousands of files.
Page 75 As the number of files in your WORDPROC and SPDSHEET directories grows, you can create additional directories subordinate to those two-like this, for example: This structure would let you segregate your business word processing files from your personal word processing files, and your sales spreadsheets from spreadsheet files used for financial projections.
Page 76: The Default Directory
The following sections discuss the basics of creating and using directories. Note: The XTREE utility provides a simple way to see and organize your directories. See the description of XTREE later in this chapter. The Default Directory MS-DOS always recognizes one directory as the current directory, just as it always recognizes one drive as the default drive.
Page 77: Using Pathnames
To change from PERSONAL back to WORDPROC, you can use the special symbol . . (two periods) or you can use an absolute pathname. (The . . symbol always designates the parent directory, which is the level above the current directory.) In other words, you can type: CD .
Page 78: And Filenames
Relative pathnames can tell MS-DOS to move upward in the directory tree as well as downward. The symbol . . (two periods) in a pathname tells MS-DOS to move upward one level in the tree. Thus, if the default directory were WORDPROC (in the above example), the pathname .
Page 79 example, suppose you are logged onto the root directory drive and you want to delete the file JEAN1204.DOC, which is stored in the directory \ WORDPROC\ PERSONAL of drive C. Enter the command as follows: \WORDPROC\PERSONAL\JEAN1204.DOC Note that if you change from one drive to another and then try to access a file on the previous drive, MS-DOS remembers which was the default directory when you were last logged onto that drive.
Page 80: Creating Directories
Note MS-DOS provides several commands that make using pathnames easy: APPEND lets you set a search path for date files and executable files so MS-DOS known where to find them even if you don' specify the drive and directory. PATH lets you specify a search path for commands and programs files;...
Page 81: Listing The Contents Of A Directory
In this case, you do not need to specify the path to the LEDGER directory because it is the default directory. Listing the Contents of a Directory You can use the DIR command to list all the files in a particular directory.
Page 82: Displaying A List Of Directories
This switch causes screenful of information. key. Another way to view a long directory listing is to use the /W switch: DIR /W This displays the directory listing in a wide format, as follows: Directory of File(s) As you can see, this type of listing does not show the size file or the time and date it was last modified.
Page 83: Removing Directories
The screen displays a report for every directory on the drive, for example: C:\LEDGER Path: Sub-directories:RECEIV If you would also like to see a list of all the files in the directories, add the /F switch to the command: TREE /F The screen displays the directory information shown above plus the names of all files in each subdirectory, for example: C:LEDGER\SALES...
Page 84: Formatting Diskettes
To delete an empty directory from a disk, use the RMDIR command, or its shorthand equivalent, RD. For example, to remove the directory ACCOUNTS, which is a subdirectory in the LEDGER directory, type the following and press Enter: RD \LEDGER\ACCOUNTS If you are currently in the LEDGER directory, you can enter the command as follows: RD ACCOUNTS...
Page 85: Formatting Diskettes On The Apex 100
Note Besides the method described below, you can also format diskettes using the Epson MENU utility. This program is easy to use because it lets you select options from a Menu. For more information, see the section on MENU later in this chapter or see your MS-DOS Reference Manual.
Page 86: Formatting Diskettes On The Apex 100\20
The formatted diskette is now ready to store data. See the MS-DOS Reference Manual for information can use with the Formatting Diskettes on the Apex 100\20 1. If necessary, type C : to log onto drive C. 2. When you see the C> prompt, type the following and press Enter: FORMAT A: You see this prompt:...
Page 87: Formatting Diskettes With One Diskette Drive (No Hard Disk)
Formatting Diskettes With One Diskette Drive (No Hard Disk) If your computer has only one diskette drive and no hard disk, follow this procedure to format a diskette: 1. Insert the working copy of your MS-DOS Startup diskette in drive A. 2.
Page 88: Backing Up Data
Backing Up Data It is very important to keep backup diskettes containing copies of the files you create. You can copy data and program files several ways: You can use the COPY or XCOPY command to copy individual files or groups of files. You can use the DISKCOPY command to make an exact duplicate of a diskette.
Page 89 If the diskette you are copying to has not been formatted, DISKCOPY formats it automatically before copying the data. The procedure for copying diskettes depends on whether you have one or two diskette drives. Follow the instructions below for your model. Using DISKCOPY with the Apex 1.
Page 90 Using DISKCOPY with the Apex 100\20 1. Make sure the diskette you want to copy is write-protected. (See Chapter 2 for instructions.) 2. If necessary, type C> 3. At the DISKCOPY A: A: MS-DOS displays this message: Insert SOURCE diskette in drive A: Press any key when ready .
Page 91 Using DISKCOPY with one drive only If your computer has only one diskette drive and no hard disk, follow these steps to copy a diskette: Make sure the diskette you want to copy is write-protected. (See Chapter 2 for instructions.) 2.
Page 92: Using The Backup Command
Using the BACKUP Command Use the BACKUP command to back up the data on your hard disk. It provides a convenient and efficient way to copy the files on your hard disk. BACKUP allows you to do the following: Split large files across two or more diskettes Copy only those files chat have been modified since the most recent backup Copy only those files that have been created (or modified)
Page 93: Special Epson Utilities
Special Epson Utilities Epson has included several time-saving utilities to make MS-DOS easier for you to use: HELP lets you display information on the screen about any MS-DOS command. MENU provides an easier way to run many of the most common MS-DOS commands.
Page 94 To use the HELP menu, follow these steps: HELP Type at the MS-DOS command prompt and press Enter. 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 screen of information command you selected, you see the prompt PgUp at the top of the screen.
Page 95: Using Menu
can also request help information for more than one command. Follow these steps: 1. At the command prompt, type names of the commands you want information about. Then press Enter. Separate each command name with a space. For example, to see help information for the DISKCOPY, FORMAT, and COPY commands, type the following and press Enter: HELP DISKCOPY FORMAT COPY...
Page 96 2. Type MENU at the command prompt and see this main menu: Enter DOS Command 3. To select an option, use the arrow keys to highlight your selection and then press Enter. Most options contain submenus; keep highlighting your selection and pressing Enter until you have selected the desired operation.
Page 97 Because you can perform so many tasks from the Mode Settings submenus, this option is a simpler alternative to the MS-DOS MODE command. Lets you access the Epson HELP program. Lets you run other MS-DOS commands without leaving the MENU program.
Page 98: Using Xtree
Using XTREE 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 especially useful for managing the data on a hard disk, where you may have hundreds of files.
Page 99 This menu provides the following information: Path: PILE DISK 3-40 Using MS-DOS With Your Computer Shows the pathname for the current directory. A single backslash identifies the root directory. The directory structure illustrated under this backslash reflects the organization of the directories on the disk.
Page 100 DISK Statistics Files window DIR COMMANDS Displays all the key commands you can You use the cursor keys, letter keys, function keys, the Ctrl key, and the Alt key to perform various functions in XTREE. Use the cursor keys to move the highlighted bar. To select a file or directory, use the arrow keys to highlight the name of the file or directory.
Page 101 Function keys control XTREE itself. Press F2 to display a screen of help information, or F3 to cancel a command. XTREE displays the available commands and the key that executes each command on the lower right comer of your screen. There are many ways you can put XTREE to work.
Page 102: Using An Autoexec.bat File
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 in a special file called AUTOEXEC.BAT. When you load MS-DOS, it always looks for this file.
Page 103: Creating An Autoexec.bat File
Creating an AUTOEXEC.BAT File You can create an AUTOEXEC.BAT file using any command or program that lets you create a text-only file. If you have a word processing program that can save a file as a text-only file (sometimes called an ASCII text file), you can use that program to create your AUTOEXEC.BAT file.
Page 104: Using Hdcache For The Hard Disk
3. Now enter the commands you want to include in the file. Type them exactly as you want MS-DOS to execute them, and in the order you want to perform them. Press Enter at the end of each line. After you type the last command, press Enter to move the cursor to the next blank line.
Page 105: Installing Option Cards
If you have the Apex 100\20, another slot contains the hard disk drive controller card. Option cards are made by Epson as well as other vendors. In addition, multifunction cards allow you to add more than one feature per slot.
Page 106: Removing The Cover
Removing the Cover Before you install an option card in your computer, you need to remove the cover. WARNING Never open the case of the computer while it is plugged into an electrical outlet. Turn off the power switch of the computer and any other peripheral devices connected to it;...
Page 107 3. The top cover is secured by two screws on each side of the computer. The two screws on the left side of the unit are covered by small plastic inserts, as shown below. Gently remove the inserts with a small screwdriver; then remove the screws on both sides of the computer.
Page 108: Inserting An Option Card
Inserting an Option Card Most option cards can be placed into any of the option slots. Some cards, however, must be installed in a specific slot. Check the option card manual to see if your option card must go in a specific slot. If you are installing a new video card, you must remove the MGA card that comes installed in your computer.
Page 109 2. Put the option slot cover in a safe place in case you later remove the option card. Keep the screw and washer. You will use them to secure the option card to the computer. If you select one of the two slots that has a grounding tab attached, be sure to replace it in step 6.

Page 131: Appendix A Changing Dip Switches And Using Setup
Appendix A Changing DIP Switches and Using Setup This Appendix describes how to change the DIP switches on the front panel of your computer and how to run the Setup program on your Reference diskette. You may need this information if you have changed the physical configuration of your computer or you want to set the parameters for a serial port.
Page 132: Dip Switch Set 1 (Internal Operations
Note Set the DIP switches only while your computer is off. Because software programs check the settings each time you cum on the system, do not change the settings while a program is running. Your computer has two sets of DIP switches; set 1 contains eight switches which control the computer’s internal operations, and set 2 contains four switches which control the parallel and serial ports.
Page 133 Switch 1 (keyboard type)—tells your computer what kind of keyboard you are using. If you are using the keyboard chat came with your computer, this switch should be ON to select the standard keyboard. If you have purchased an enhanced (101 - key) keyboard co use with the computer, set this switch OFF.

Destructive Surface Analysis this option to accurately locate any bad tracks on a hard disk, and to flag any bad tracks that are not flagged. WARNING If any errors occur during this check, all data on the track that produces the error is destroyed. For this reason, if you think that an unflagged bad track is causing trouble, first run option 4, Non-destructive surface analysis, to check the disk surface.
Page 206: Non-Destructive Surface Analysis
If the program finds one bad track that is not flagged, the summary would show one track with a write, read error. The report is then followed by a table like this: To flag the error tracks as bad, press Y and Enter. You then see a list of the tracks as they are flagged and then these messages: Flagging bad tracks...
Page 207 When ‘the analysis is complete, the program displays a summary of the status of the disk. This summary lists the following: Flagged bad tracks Tracks with read, verify errors Good tracks. no errors occur, you see this message: No read, verify error was detected. If errors are found, the program displays a table of the tracks that gave errors, similar to the one displayed by the destructive analysis.
Page 208: Appendix F Preparing A Hard Disk For Use
This type of formatting is usually done by the manufacturer and you should not need to this yourself. If you are using an Epson drive, it has already been formatted. However, you may need to perform a low-level (also called physical) format if one of the following is true: The hard disk is new and has never been formatted.
Page 209: Creating The Ms-Dos Partition
The hard disk you are using has been producing numerous read/write errors. See Appendix E for instructions on performing a low-level format. If you need to format the disk, be sure to do it before completing the steps in this appendix. WARNING The procedures described in this appendix destroy any data on the hard disk.
Page 210 : and press Enter to log onto drive A. Type At the A> prompt, type screen displays the FDISK options menu. Press 1 to select the Create DOS partition option and press Enter. Press 1 to select the Create Primary DOS partition option and press Enter.
Page 211: Formatting The Ms-Dos Partition
Formatting the MS-DOS Partition Once you have created the MS-DOS partition, you must format it for MS-DOS. Use the MS-DOS SELECT command to format the new partition, drive C. SELECT automatically does the following: Formats the partition Labels the partition Copies the MS-DOS system files to the hard disk.
Page 212 The screen displays this message and prompt: SELECT is used to install DOS the first time. SELECT erases everything on the specified target and then installs DOS. Do you want to continue (Y/N)? 3. Press Y. Formatting does not begin immediately. The screen displays the following message: WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST!
Page 213: Copying The Remaining Files To The Hard Disk
SELECT copies the rest of the files from the Startup diskette to the hard disk. When all the files are copied, the A> prompt reappears. The partition on the hard disk is now formatted. Note The SELECT procedure described above copies all the files from your Startup diskette to a directory it created on drive C named /DOS.
Page 214: Creating The Autoexec.bat File
Note The procedure described above copies all the files on the MS-DOS and Reference diskettes to the /DOS subdirectory on drive C. You may, however, prefer to store some of these commands in other subdirectories. For information of creating subdirectories, see Chapter 3 or see your MS-DOS Reference Manual.
