To disable parity checking, turn on thi[...]

Chapter 2 Using the Equity II After you set up your system, you’re ready to turn on the power and start using your computer. But before you turn it on, read the following safety rules. Safety Rules Follow these rules to avoid accidentally damaging your computer or injuring yourself: Never turn the computer on or off with a disk protector sheet in[...]

Turn on the monitor so you can see the messages that appear as the computer starts up. If you have a printer or any other peripheral, turn it on next. You can turn on the computer with or without a system diskette in the top disk drive. For now, leave the drive empty. To turn on the com- puter, open the cover on the top right comer of the front pan[...]

You need to prepare your hard disk before you can run an operating system on it. Refer to “Using a Hard Disk Drive” in Chapter 3 and your MS-DOS (or other operating system) manual for instructions on how to prepare a hard disk for use. When your hard disk is set up to automatically boot MS-DOS, the operating system loads when you turn on the co[...]

3. Push the diskette into the slot until it clicks into place. Be careful not to force it. 4. When the diskette is in all the way, press the PUSH button on a 360KB floppy disk drive, or turn the latch on a 1.2MB floppy disk drive clockwise until it locks into the vertical position. This keeps the diskette in place while you use it, and enables the [...]

Selecting an Execution Speed The Equity II can operate at two different execution speeds. You choose between a 4.77 or a 7.16 MHz clockrate. At the faster speed, the Equity II performs all tasks more rapidly. You can select the slower execu- tion speed to run application programs that have specific timing require- ments. To select the execution spe[...]

There are three ways to reset. Because each is more powerful than the last, try them in the order listed here: 1. 2. 3. If you are using MS-DOS, hold down Ctrl and Alt and press the Del key on the numeric keypad at the right of the keyboard. The screen goes blank for a moment and then MS-DOS reloads. (The operating system must be on either the disk[...]

Chapter 3 Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and retrieve and use stored data when you like. The Equity II can have up to two disk drives. The top disk drive on the Equity II is a floppy disk drive and you can have a hard disk drive or one of two types of floppy disk drives below it. (The i[...]

Choosing Diskettes for the Equity II When you buy diskettes, be sure to choose high-quality diskettes with reinforced hub rings-the added reliability is well worth the extra cost. You also need to make sure you buy the correct format type for the drive(s) in your Equity II. The top floppy disk drive on the Equity II has a storage capacity of 360KB [...]

You can use a double-density diskette in a 1.2MB drive if you format it as a 360KB (or 320KB) diskette in the 1.2MB drive first. (Your MS- DOS or other operating system manual explains how to format a disk- ette in the density you choose.) After you do this, you can read data from it in both drive types, but write to it only when it is in a 1.2MB d[...]

Caring for Disks and Disk Drives To avoid damaging floppy and hard disks, you need to care for them properly. Take these precautions to avoid losing data: Never remove a diskette from a drive or turn off the computer while a disk drive’s LED lamp is on. The red light indicates the computer is copying data to or from a disk. If you interrupt this [...]

If you have a hard disk drive, take these additional precautions: l Never turn off the computer’s power when the hard disk LED lamp is on. The red light indicates the computer is copying data to or from the hard disk. If you interrupt this process, you can lose data. l Never attempt to open the hard disk unit. The disk itself is enclosed in an ai[...]

Write-protecting diskettes As shown in Figure 3-1, the right edge of a diskette has a small, rec- tangular notch. If this notch is visible, you can copy new data to the diskette. If you cover the notch with an adhesive write-protect tab, you can retrieve and copy data from the diskette, but you cannot store new data on it or delete any files it con[...]

Since you may swap diskettes this way often, it is easy to forget which diskette is which. One way to avoid accidentally losing data is to hold the diskette for one drive in your left hand and the diskette for the other drive in your right. You can also place a write-protect tab on your source diskette. For more information on using a single floppy[...]

The MS-DOS system diskette contains all these programs and the MS-DOS manual describes how to use them. If you plan to use an oper- ating system other than MS-DOS, you need to use that operating system to partition the hard disk and copy the system files to it. The Epson hard disk is formatted at the factory. Therefore, you need not format it befor[...]

Chapter 4 Installing Option Cards Option cards are accessories you can install in your Equity II to pro- vide extra capabilities. For example, you can add a hard disk, another monitor, an auto-dial modem, or a mouse. The Equity II has five slots for S-bit option cards so it can hold up to five cards. If your Equity II has a hard disk, a hard disk c[...]

Installing an Option Card You can install most option cards in any available slot. However, some cards work only in a specific slot. If you have such a card, your option card manual tells you which slot you need to use. Since the hard disk controller card must be connected to the hard disk, this card occu- pies slot 5, which is closest to the hard [...]

5. Once the connector pins are sitting in the connector slot, push the card downward firmly (but carefully) to fully insert it as shown in Figure 4-4. If the card does not go in smoothly, do not force it-pull it all the way out and try again, being sure to keep it straight. Figure 4-d. Inserting an option card 6. Secure the card’s metal retaining[...]

Notice that each access slot cover on the back panel is secured by a tab at the bottom and a clip at the top.
