Page 20: Using Your Computer
Chapter 1 Using Your Computer This chapter gives you a brief overview of some basic computer operations that you’ll use on a daily basis, such as how to turn your system on and off, use diskettes and disk drives, and reset the computer.
Page 21: Turning On The Computer
Turning On the Computer Before turning on your computer, check the following safety rules to avoid accidentally damaging your computer or injuring yourself: Cl Do not connect or disconnect any power cables or peripheral device cables (including the mouse or keyboard) when the computer’s power is on.
Page 22 3. To turn on the computer, press the power button located on the right side of the front panel, as shown below. The power indicator below the button lights up. After a few seconds, the computer displays a count of its system memory, and then performs its power-on diagnostics.
Page 23: Turning Off The Computer
Note If your computer’s configuration does not match the information stored in the computer’s CMOS RAM (defined through the SETUP pro am), you see an error message and a prompt to press the ?3 SETUP program to correct the information. (See Chapter 2 of the Setup Guide for instructions.) If you do not want to run SETUP, ignore the prompt.
Page 24: Using Disks And Disk Drives
3. Remove any diskette(s) from the diskette drive(s). 4. Press the power button to turn off the computer and then turn off any peripheral devices (monitor, printer, etc.). If you need to move your computer, always wait at least 20 seconds after turning it off before you move it. This allows your hard disk drive’s read/write heads to move away from the disk to a safe location.
Page 25: How Disks Store Data
How Disks Store Data Diskettes are made of flexible plastic coated with magnetic material. This plastic is enclosed in a square jacket that is either slightly flexible (5.25-inch diskette) or hard (3.5-inch diskette). Unlike a diskette, a hard disk is rigid and fixed in place. It is sealed in a protective case to keep it free of dust and dirt.
Page 26: Types Of Diskette Drives
Double-sided, double-density diskettes have either 40 or 80 tracks on each side, and double-sided, high-density diskettes have 80 tracks on each side. Diskettes can have 8,9,15, or 18 sectors per track. A hard disk consists of two or more platters stacked on top of one another and thus has four or more sides.
Page 27: Drive And Diskette Incompatibilities
1.2MB drive-Use 5.25-inch, double-sided, high-density, 96 TPI, 1.2MB diskettes. These diskettes contain 80 tracks per side, 15 sectors per track, and hold up to 1.2MB of information (approximately 500 pages of text). 720KB drive-Use 3.5-inch, double-sided, double-density, 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).

Page 29: Caring For Diskettes And Diskette Drives
Caring for Diskettes and Diskette Drives Follow these basic precautions to protect your diskettes and avoid losing data: P Remove all diskettes before you turn off the computer. P Do not remove a diskette from the diskette drive or reset or turn off the computer while the drive light is on.
Page 30 Q Do not place diskettes on top of your monitor or near an external hard disk drive. Always hold a 5.25-inch diskette by its protective jacket and never touch the magnetic surface (exposed by the read/write slot). The oils on your fingertips can damage it. Q Never wipe, brush, or try to clean diskettes in any way.
Page 31: Write-Protecting Diskettes
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 it or delete any files it contains. To write-protect a 5.25-inch diskette, cover the small, rectangular notch (shown below) with an adhesive write-protect tab.
Page 32 On a 3.5-inch diskette, the write-protect device is a small switch on the back of the diskette in the lower right comer, shown below. To write-protect a 3.5-inch diskette, slide the switch toward the edge of the diskette until it clicks into position, exposing a hole in the comer.
Page 33: Inserting And Removing Diskettes
Inserting and Removing Diskettes If you have a 5.25-inch diskette drive, insert a diskette as follows: hold the diskette with the label facing up and the read/write slot leading into the drive, as shown below. Slide the diskette all the way into the slot. Then turn the latch down to lock it in a vertical position.
Page 34 If you have a 3.5-inch diskette drive, insert the diskette with the label facing up and the metal shutter leading into the drive, as shown below. Slide the diskette into the drive until it clicks into place. metal shutter When you want to remove the diskette, make sure the drive light is off;...
Page 35: Using A Single Diskette Drive System
Using a Single Diskette Drive System Most operating systems expect the computer to have at least two diskette drives and display prompts and messages accordingly. MS-DOS, for example, recognizes the first diskette drive (the top drive) as drive A and a second diskette drive as drive B.
Page 36: Formatting Diskettes
Formatting Diskettes Before you can store data on a new diskette, you must format it. Formatting prepares the diskette so that the operating system can write data on it. You need to do this only once, before you use the diskette for the first time. You can also reformat previously used diskettes to store new data.
Page 37: Using A Hard Disk Drive
Using a Hard Disk Drive Using a hard disk is similar to using a diskette. However, the hard disk provides several advantages: P A 240MB hard disk can store as much data as approximately 198 1.2MB diskettes or 165 1.44MB diskettes. P Your computer can perform all disk-related operations faster.
Page 38: Backing Up The Hard Disk
Backing up the hard disk While the hard disk is very reliable, it is essential to back up your hard disk files to diskettes or tapes 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.
Page 39: Special Keys On The Keyboard
Special Keys on the Keyboard Certain keys on your keyboard serve special functions when your computer is running your operating system or application programs, as described in the table below. key functions Special Ishml 1-20 Using Your Computer Moves the cursor one tab to the right In normal mode and one tab to the left in Shift mode.

Page 41: Resetting The Computer
Resetting the Computer Occasionally, you may settings or its memory without turning it off. You can do this by resetting the computer. For example, if an error occurs and the computer does not respond to your keyboard entries, you can reset it to reload your operating system and try again.
Page 42: Locking The Computer's Cover
If resetting the computer does not correct the problem, you probably need to turn it off and on again to reboot it. Remove any diskette(s) from the diskette drive(s). Turn off the computer and wait 10 seconds. If you do not have a hard disk, insert a system diskette in drive A.
Page 43: Using A Password
Using a Password If you set a password when you ran the SETUP program, you must enter it every time you turn on or reset the computer. Follow these steps to use your password: If you do not have a hard disk, insert your system diskette in drive A.
Page 44: Changing A Password
Note If you turned on network server mode when you ran the SETUP program, you need to use a different procedure to enter your password. See “Using Your Computer as a Network Server” on page 1-27. Changing a Password To change your password, follow these steps: 1.
Page 45: Deleting A Password
Note You can also change your password using the SETUP program. See Chapter 2 of the Setup Guide for instructions. Deleting a Password To delete your password, follow these steps: 1. If you do not have a hard disk, insert your system diskette in drive A.
Page 46: Using Your Computer As A Network Server
Using Your Computer as a Network Server A network server is the master computer in a network and provides storage space for the other computers connected to it. It can also write files to and read files from the other computers, making it the most powerful computer in the network.
Page 47: Using A Password In Network Server Mode
You do not have to set a password in network server mode to use your computer as a network server, but it is helpful. See “Setting the Password Options” in Chapter 2 of the Setup Guide for instructions on setting the password and enabling network server mode.
Page 48: Changing The Processor Speed
Changing the Processor Speed Your computer’s processor can operate at two speeds: high or low. High speed is the highest speed at which your microprocessor is capable of running, such as 33 MHz. Low speed simulates an 8 MHz processor to provide compatibility with older application programs.
Page 49 Some copy-protected programs require the computer to run at low speed while accessing the program on a diskette. These programs also usually require you to leave a key disk-the diskette that contains the copy protection-in the diskette drive. If you use a copy-protected program often, you may want to set your processor speed to change automatically to low speed when accessing the diskette and return to high speed when it is finished.
Page 50: Entering Keyboard Commands
If you frequently use programs that require low or automatic speed, use SETUP to change the processor speed. Your new setting remains in effect until you change it again using SETUP. See Chapter 2 of the Setup Guide for instructions. If you use these programs only occasionally, you should use the keyboard commands or the ESPEED program (described below) to change the processor speed.
Page 51: Using The Espeed Program
Note You can use the commands listed above while you are running a program. However, if the program uses one of these commands for another function, you cannot use it to change the processor speed. For example, if you are running a program that uses the [cbll[m - the cursor, you cannot enter [mJIm1[-1 to change the processor speed to low.
Page 52 To run SPEED, prompt and ESPEED You see the following messages: Usage: ESPEED[/H] [/L] /High Set High speed (no Auto) Set Low speed (no Auto) /LOW /Auto set Auto speed These messages tell you the switches you should use to set the speed to high, low, or automatic.
Page 53: Changing The Speaker Volume
Entering the ESPEED command in a butch file You may want to run the ESPEED program by including the command in a batch file. For example, let’s say you have a program called SLOWDOWN which requires a slower processor speed. You could include the following commands in a batch file to start the SLOWDOWN program: ESPEED SLOwDO?IN...
Page 54 Follow these steps to run SETVOL: 1. If you copied SETVOL.EXE to your hard disk, log onto the directory where it is stored. If you did not copy the file, insert the Reference diskette in drive A and log onto that drive. 2.
Page 55: Preparing The Hard Disk For Moving
This protects the hard disk from being damaged if the computer is bumped accidentally. Many hard disk drives, including all Epson drives, automatically park their heads when you turn off the computer. If your hard disk drive does not do this, or if you are not sure that it does, be sure to run HDSIT.
Page 56: Using Autoexec.bat And Other Batch Files
If you have not already done so, copy the HDSIT.COM and HDSIT.VER files from the Reference diskette to your hard disk. Then, when you want to run HDSIT, log onto the directory files are stored. where these You see a message on the screen that tells you the disk drive’s read/write heads will remain locked until you reset the computer or turn the power off and on again.
Page 57 One batch file that you may find particularly useful is called AUTOEXEC.BAT. Every time you turn on your computer, MS-DOS looks for the AUTOEXEC.BAT file and automatically executes each of the commands in the file. When you install MS-DOS, it creates an AUTOEXEC.BAT file for you, which you can modify or replace as described above.

Although your drive may look different from the ones illustrated here, you should be able to install it the same way. If you are installing or removing a non-Epson drive, some of the steps in this chapter may not apply; see the documentation that came with your drive for more information.
Page 105: Choosing The Correct Drive Bay
before you perform any of the procedures described below, remove the computer’s cover as described in Chapter 2. You may also need to remove the front panel and subassembly; the instructions in this chapter tell you when this is necessary. Choosing the Correct Drive Bay Your system can hold up to five drives.
Page 106: Installation/Removal Sequence
You can install either one full-height or two half-height hard disk drives in the internal drive bay. If you are installing a hard disk, it is best to install it in the internal bay. This reserves the external bay for any devices that need to be accessible from the outside, such as a diskette drive or tape drive.
Page 107: Checking The Ide Hard Disk Drive Jumpers
Checking the IDE Hard Disk Drive Jumpers IDE (Integrated Drive Electronics) hard disk drives have jumpers that must be set for the drive to work properly with your computer. The jumpers tell the computer whether you are using one hard disk drive or two. If you purchased your system with a hard disk drive already installed, these jumpers have been set for you.
Page 108: Where To Go Next
Note If you are removing one hard disk drive and leaving one in your computer, be sure to set the jumpers on the remaining drive to indicate that you have only one hard disk drive. Where to Go Next If you are installing your first hard disk drive (i.e., there is no other hard disk in your computer), you should install it in the internal drive bay.
Page 109: Installing A Drive In The External Bay
Installing a Drive in the External Bay This section describes how to install an Epson diskette drive; however, you can use these instructions to install another type of storage device in the external bay. See the manual that came with it for additional installation instructions.
Page 110 Follow these steps to install a disk drive in the external bay: 1. Locate the following parts included with your computer: Cl Two metal drive brackets Q Four retaining screws (with attached flat washers) P Two nuts (with attached star washers) 0 Small wrench.
Page 111 3. Slide the drive into the bay as shown below, guiding the bracket screws on each side along the appropriate grooves in the drive bay. Guide the holes in the front of the brackets over the threaded posts on the front of the subassembly, as shown above. Then push the drive into the bay so that the bracket lies flush against the front of the drive bay.
Page 112: Connecting The Cables
7. When the drive position is correct, remove the nuts securing it to the drive bay and pull it gently out of the bay. Then tighten the four screws on the brackets, slide the drive back into the bay, and replace the two nuts. 8.

Locate the diskette drive ribbon cable. (One end is connected to the main system board and the other end, is attached to the top diskette drive.) To connect diskette drive B, use the connector...
Page 114 3. If you are connecting a hard disk drive, locate the hard disk drive ribbon cable. It is a flat cable with a red wire running down one side. (If you are installing your second drive, one end of the cable is connected to the main system board and another connector is already attached to the hard disk drive in the internal drive bay.
Page 115 4. Locate one of the five power supply cables secured by the clasps on the side of the subassembly. The cables are labeled through P5; you can use any one of them. Position the cable connector so its notched corners line up with the notched comers of the power supply socket on your drive, as shown below.
Page 116 6. If you installed a hard disk drive, skip to step 7. If you installed a diskette drive, tape drive, or other accessible drive, you need to remove the slot cover for that drive from the front panel. Turn the front panel so you are looking at the inside.

Removing a Drive From the External Bay Follow these steps to remove a drive from the external bay: 1. Disconnect the power supply and drive cables from the back of the drive you want to remove, as shown below. power supply cable drive cable 2.
Page 118 3. Grasp the front of the drive and pull it out of the bay. Note If you removed an IDE hard disk drive from the external bay and it is your only hard disk drive, you must also remove the hard disk drive cable from its connector on the main system board.
Page 119 Before you install a hard disk drive in the internal drive bay, read the following guidelines: The internal drive bay can accommodate only half- or full-height hard disk drives that are 3 M inches wide. If you are installing your first half-height hard disk drive, install it in the position farthest from the power supply.
Page 120 Follow these steps to install a new hard disk drive (or reinstall a drive you removed) in the internal bay: 1. Your hard disk drive may have come with mounting frames attached to each side of the drive, as shown below. On one side, there may also be a plastic guiderail.
Page 121 If a plastic guiderail is attached, remove the screws securing the guiderail and the metal grounding plate to one of the mounting frames, as shown below. 2. Remove the two screws securing the mounting frames to each side of the drive. 4-18 Installing and Removing Drives...
Page 122 3. Position the drive above the drive bay, as shown below. Make sure the power supply and drive sockets face the front of the subassembly. Then lower the drive into the bay. 4. Adjust the drive’s position so the four holes on the drive are aligned with the corresponding holes in the drive bay.
Page 123: Connecting The Cables
Connecting the Cables To connect the drive to the computer, you’ll attach it to two cables: a power supply cable and a drive ribbon cable. Follow these steps to connect the cables: 1. If the subassembly is out of the computer, follow the steps in Chapter 2 to replace it.
Page 124 4. If the drive you installed is the second hard disk drive (there was already one installed), go to step 7. If the drive you installed is the only hard disk drive, you need to attach the hard disk drive ribbon cable to the main system board.
Page 125 To attach the cable to the main system board, select a connector on one end of the cable. Align the small tab in the middle of the connector with the notch on the socket, as shown below. notch (If you need to connect the diskette drive cable to the main system board as well, use the connector with a tab on one end of the cable and insert it as described above.) If you have difficulty reaching the socket, you can remove...
Page 126 6. Thread the cable through the rear clasp on the side of the subassembly, as shown below. (You may have to fold the cable as shown.) Then snap the clasp shut. 7. Now you can attach the hard disk drive cable to your drive. If only one hard disk drive is installed, you can use either of the two free connectors on the cable.
Page 127 The connector has two rows of holes designed to fit over the pins in the drive socket. Notice the red wire running down one side of the cable. This wire helps you orient the cable connector to the drive socket. Align the connector with the socket so the side of the cable with the the red wire faces the drive’s power supply socket, as shown below.
Page 128: Removing A Hard Disk Drive From The Internal Bay
Removing a Hard Disk Drive From the Internal Buy Follow these steps to remove a hard disk drive from the internal drive bay: 1. If you are removing a hard disk drive in the position next to the power supply, first remove the subassembly as described in Chapter 2 2.
Page 129 3. Remove the four screws securing the drive to the internal drive bay. Then lift the drive out of the bay and set it aside. Note If you removed one IDE hard disk drive and are leaving another one in the system, you must set the jumpers on the remaining drive to indicate that you have only one IDE drive installed.
Page 130: Post-Installation Procedures
2. If you installed a hard disk drive that did not receive a low-level format, you need to format the drive before you can use it. (All Epson drives are sold already formatted.) Check the manual that came with the drive to see if it is already formatted.

Page 141: Formatting A Hard Disk
You may need to use the procedure in this chapter to physically format a hard disk if you installed a non-Epson hard disk in your computer that has never received the low-level format and did not come with its own format utility. If you installed a hard disk that came with its own format utility, use that program to physically format the disk.
Page 142: Starting The Program
Note Sometimes, after a hard disk has been used for a long time, its data becomes fragmented, causing the disk to perform less efficiently or produce errors. If this happens, check your operating system manual for procedures you can perform to reorganize your data on the hard disk.
Page 143: Formatting A New Disk
Other hard disks (such as Epson disks) come with the bad tracks already flagged. Reformatting a Used Disk To reformat a disk you have been using follow these steps: Use the Nondestructive surface analysis option to check for unflagged bad tracks.
