Page 36: Running The Setup Program
Chapter 2 Running the SETUP Program When you use your computer for the first time, you need to run the SETUP program to define how your system is set up. This is a simple procedure which you must do at least once. You may need to run it again later if you change some part of your configuration.
Page 37: Starting The Setup Program
The configuration you define through SETUP is stored in a special area of memory called CMOS RAM. This memory is backed up by a battery, so it will not be erased when you turn off or reset the computer. Whenever you reboot the computer, it checks the settings, and if it discovers a difference between the information in the CMOS RAM and your system’s configuration, it prompts you to run SETUP.
Page 38: Selecting Options
The menu automatically displays the base memory size, the extended memory size, and whether a math coprocessor (numeric processor) is installed. Additionally, the SETUP menu lists the parameters you can change. S e l e c t i n g O p t i o n s A solid cursor bar highlights the parameter currently selected.

Page 58: Using Disks And Disk Drives
If you do not enter the correct password the first time, press and try again. Enter If you want to change or delete your current password, you must run the SETUP program. See Chapter 2 for instructions. Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use your stored data.
Page 59 All disks are divided into data storage compartments by sides, tracks, and sectors. Double-sided diskettes store data on both sides. On each side are concentric rings, called tracks, on which a disk can store data. A disk is further divided by sectors, which are similar in shape to pie slices.
Page 60: Types Of Diskette Drives
Your computer uses the read/write heads in a disk drive to store and retrieve data on a disk. To write to a disk, the computer spins it in the drive to position the disk so that the area where the data is to be written is under the read/write head.
Page 61 0 360KB drive-Use 5 1/4-inch, double-sided, double-density, 48 TPI, 360KB diskettes. (You can also use single-sided, 160KB or 180KB diskettes.) These diskettes contain 40 tracks per side and 8 or 9 sectors per track. With 8 sectors per track, a diskette holds up to 320KB. With 9 sectors per track, a diskette holds up to 360KB of information, which is approximately 150 pages of text.
Page 62: Caring For Diskettes And Diskette Drives
Because of these incompatibilities, always indicate the diskette type and density when you label your diskettes. (Usually this information appears on the manufacturer’s label.) If you have any combination of the above drives (1.44 MB, 1.2MB, 720KB, or 360KB), you can copy files from one drive to another-using COPY or XCOPY-as long as the correct diskette type is in each drive.
Page 63 0 Keep diskettes in a moderate environment. Don’t leave diskettes sitting in the sun, or in extreme cold or heat. 0 Keep diskettes away from magnetic fields, such as electrical appliances, telephones, and loudspeakers. (Remember that diskettes store information magnetically.) Q Do not place diskettes on top of your monitor or near an external hard disk drive.
Page 64: Write-Protecting Diskettes
W r i t e - p r o t e c t i n g D i s k e t t e s 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.
Page 65 On a 3M-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 3M-inch diskette, slide the switch toward the edge of the diskette until it clicks into position, exposing a hole in the comer.
Page 66: Using A Single Diskette Drive System
U s i n g a S i n g l e D i s k e t t e D r i v e S y s t e m MS-DOS expects the computer to have at least two diskette drives and displays prompts and messages accordingly.
Page 67: Inserting And Removing Diskettes
You can load MS-DOS from an application program diskette if that diskette contains the operating system This means it is a bootable diskette. See your MS-DOS manuals for information about creating a system diskette. Inserting and Removing Diskettes If you have a 51/4-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.
Page 68 If you have a 3 1/2-inch diskette drive, insert the diskette with the label facing up and the metal shutter leading into the drive, as shown in the following illustration. Slide the diskette into the drive until it clicks into place. When you want to remove the diskette, make sure the drive light is off;...
Page 69: Formatting Diskettes
F o r m a t t i n g D i s k e t t e s Before you can store data on a new diskette, you must format it using the FORMAT command. Formatting prepares the diskette so that MS-DOS can write data on it. You need to do this only once, before you use the diskette for the first time.
Page 70: Using A Hard Disk Drive
U s i n g a H a r d D i s k D r i v e Using a hard disk is similar to using a diskette. However, the hard disk provides several advantages: A 40MB hard disk can store as much data as approximately thirty-three 1.2MB diskettes, and a 100MB hard disk can store as much data as approximately eighty-two 1.2MB diskettes.
Page 71 This protects the hard disk from being damaged if the computer is bumped accidentally. Many hard disk drives, induding 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 72 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. The computer locks the heads and disables the keyboard. Remove any diskettes and turn off the computer.
Page 73: Enhancing System Operations
Chapter 4 Enhancing System Operations This chapter tells you how to use the following procedures to enhance the operation of your computer: 0 Using AUTOEXEC.BAT and other batch files 0 Changing the processor speed Using expanded memory beyond 640KB Using the VGA utilities. Using AUTOEXEC.
Page 74: Changing The Processor Speed
When you install MS-DOS, it creates an AUTOEXEC.BAT file for you. To modify the file or replace it with a new one, you can use the COPY or EDLIN command, a text editor, or a word processing program that can save a file as a text-only file.
Page 75 There are different types of copy-protected programs. Depending on the type you have, you may or may not want to set the processor to automatic speed. Follow these guidelines: 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 on high speed.
Page 76: Entering Keyboard Commands
Entering Keyboard Commands You can change the processor speed by entering one of the commands shown in the following table. Speed setting commands To enter these commands, hold down the Ctrl key and the Alt key simultaneously and then press the 2, +, 1, or - key. Use the + or - key on the numeric keypad or the 1 or 2 key on the main keyboard.
