Chapter 2 Using Your Equity I+ Once you have set up your Equity I+, you’re ready to take advantage of its versatility. This chapter describes the special keys on the keyboard, how to change your computer’s operating speed, and how to reset and turn off your computer. It also explains how to use and care for your disks and disk drives. Special Keys Certain keys serve special functions and are used in various ways by application programs. Some of the more important keys are shown in Figure 2-1. Table 2-1 describes each of these keys as well as others with special functions. Figure 2-1. Eq..

Resetting the Computer You may occasionally need to reset the computer, either to load a differ- ent operating system, or because a program has failed and the computer does not respond to your keyboard..

Turning Off the Computer - Page 33

There are three ways to reset; you should use them in this order: 1. If you are using MS-DOS, press Ctrl and Alt together with the Del key on the numeric keypad at the right of the keyboard. The screen goes blank for a moment, and any system disk in drive A reloads. If the problem is not corrected after trying this, try the second method. 2. Press the RESET button under the hinged flap beneath the disk drives. This method works even when the keyboard is not responding. If this fails to have any effect, try the third method. 3. Remove any diskettes from the disk drives. Turn off the monitor ..

How disks work - Page 34

How disks work The floppy disks (diskettes) you insert in your system’s floppy disk drives are round pieces of flexible plastic coated with magnetic material and enclosed in protective jackets. Like a record, a diskette has circular tracks on both sides. The computer stores the data you enter as magnetic patterns on these circular tracks. A small read/write head in the disk drive interprets the magnetic pat- terns. When a diskette is in a drive, the read/write head is right over the large oval hole in the diskette jacket. This hole allows the read/write head to access the diskette when yo..

2-6 - Page 35

l l l l l l l l l l Keep disks away from magnetic fields. (Remember that disks store their information magnetically.) There are many sources of magnetism in and around your home or office, such as electrical appliances and tele- phones, and particularly loudspeakers. Keep disks in a moderate environment. They work best at normal room- temperature and humidity conditions. Never leave them sitting in the sun, or in extreme cold or heat. The temperature inside a car in the middle of summer or winter can cause severe damage. Never touch the diskette’s magnetic surface. The oils on your finger..

Inserting and removing diskettes - Page 36

l Never attempt to open the hard disk unit. The disk itself is enclosed in an air-tight container to protect it from dust. l If you plan to move the hard disk unit, the read/write head must be moved away from the disk recording area. The MS-DOS program to protect the read/write head is HDSIT. Refer to your Diagnostics or MS-DOS manual for details. Inserting and removing diskettes To insert a diskette into a disk drive, hold it with the label face up and the write-protect notch to the left (so that the read/write slot is away from you). Then slide it into the disk drive as shown in Figure 2-..

Figure 2-4. Write-protect notch - Page 37

Note: You need to format your blank diskettes before you can use them with your operating system. Refer to your MS-DOS or other operat- ing system manual for instructions on how to format your blank diskettes. There are two ways to avoid losing the valuable information stored on your disks; write-protect your diskettes and make backup copies. Both of these methods are described below. Write-protecting diskettes You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can copy data from it, but you cannot store new data on the diskette ..

Write-protected Write-protect - switch Figure 2-5. Write-protect switch To unwrite-protect a 31/2” diskette, move the switch up toward the center of the diskette so the hole is covered. Making backup copies It is a good idea to make copies of all your important data and program diskettes. With program diskettes, or the system master diskette supplied with your Equity I + , you should use backup copies, and keep the originals in a safe place-away from your working disks. Copy your data disks regularly (preferably daily), and keep them apart from the originals. Your MS-DOS manual describes ..

Using a hard disk drive - Page 39

An operating system expects the computer to have at least two physical disk drives. MS-DOS recognizes drives A and B for two floppy disk drives, or A and C for a floppy and a hard disk drive. Some operations, such as copy- ing files from one disk to another, require two drives. With MS-DOS, if you have only one physical disk drive, the operating system lets you treat it logi- cally as two drives. For example, if you give a command to copy from drive A to drive B, MS-DOS copies from the first diskette you place in the drive (A) to the computer’s memory. Then it prompts you to insert the di..

Chapter 3 Installing Option Cards Option cards are accessories you can add to your Equity I+ to provide extra system capabilities. For example, you may want to install a memory expansion card or an auto-dial modem. You can install up to five option cards in the Equity I+ at one time, but one position is always occupied by the video card that operates your moni- tor. Option cards are available from Epson as well as other vendors. In addi- tion, multifunction boards (available from other vendors) allow you to add other features without using additional slots.

Lower the cover onto the bottom half of the case, as shown in Figure 3-6, making sure that the bottom edges fit inside the case. At the same time, slide the front edge beneath the top edge of the front panel. Finally, lower the back of the cover so that it is in position. Figure 3-6. Rep..

Post-installation Setup - Page 47

Post-installation Setup After you install an option card (and replace the main unit’s cover and reconnect the power cord and peripherals), you may need to change your DIP switches to update the configuration information. For example, if you add a floppy disk drive, you need to change switches 1-7 and 1-8 so the computer knows it has the additional drive. You may also need to add some commands in the configuration files on your system disk as well. See your MS-DOS manual for instructions. When you finish installing an option card and reconfiguring the system, you should test the option if ..

3. Is the diskette write-protected? A write-protect tab or switch may be in place to protect the data on the disk. Think twice before removing the tab or moving the switch. It might be a new diskette, but it might also be a diskette with information you do not want to change or lose. Check the diskette directory to determine what files it contains. The operating system manual gives the proper directory command. Although you should normally write-protect program diskettes, there are some pro- grams which use the program diskette for temporary files, and these do not work if the diskette has ..

If a different cable was supplied to connect the drives to the optional controller card, make a careful note of how the original drive cable was connected, and remove it from the computer. Keep it in a safe place, in case you need to remove the optional controller for any reason. FRONT J2 / 6M and 6N / 7M and 7N Figure ..

Jumper J2, Parity RAM - Page 54

Jumper J2, Parity RAM Parity RAM enables the computer to make sure that the data stored in its memory is valid. The Equity I+ can support parity RAM to give you added protection against loss of data. Installation of parity RAM is a simple process, but you should ask your dealer to do it for you, as well as test the RAM carefully. If you decide to install the parity RAM yourself, follow the instructions below carefully. You need to install four RAM chips. After you remove the cover of the computer (see “Removing the Cover” in Chapter 3) locate sockets 6M, 6N, 7M, and 7N. See Figure A-2. ..

Formatting a Hard Disk - Page 87

Chapter 3 Formatting a Hard Disk This chapter describes how you check or format a hard disk drive after installation. After the hard disk is formatted, it can be partitioned and for- matted for a particular operating system. Formatting destroys all data on the hard disk, in all partitions, so use this program with extreme care. Format hard disk is option 2 on the OPERATION MENU. You can select this option from the OPERATION MENU, or you can execute the MS-DOS HDFMTALL command. After you install a hard disk drive, format it using this program, Format hard disk, and choose option 1, Condition..

Enter drive letter (C/D)? - Page 88

The first two options format a hard disk. Normally you use option 1, Conditional format (Normal). This option automatically locates any bad tracks that are Pug& by the manufacturer and marks them so that they are never used. Option 2, Unconditional format, requires you to enter the list of bad tracks. The other two options test a hard disk for problems. Use option 3, Destructive surface analysis, to test the entire disk and update the bad track table. Because this option writes data to the disk as well as reads it, all data on any track that produces an error is destroyed. To check for ..

Conditional Format (Normal) - Page 89

Conditional Format (Normal) Use this option to format the hard disk. All flagged tracks are marked so that they are never used. To start the Conditional format, press 1 and then Enter. The program starts to scan the disk to find all tracks flagged as bad, starting from the innermost cylinder of the disk. During the scan, you see the number of the cylinder being checked. For example, if you have a 20MB hard disk, the first messages you see are: Format Hard Disk Scanning for flagged bad tracks... Current cylinder is 614 When the scan is complete, the program displays information about the con..
