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 do 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

Page 58: 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 your stored data. This section explains how disks work and tells you how to: 0 Use different types of diskettes and diskette drives LI Care for your diskettes and diskette drives 0 Write-protect diskettes Ll Use a single diskette drive system...
Page 59 A disk is further divided by sectors, which are similar in shape to pie slices. The figure below provides a simple representation of tracks and sectors. 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.
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. A diskette has an exposed area where the read/write head can access it.
Page 61 Cl 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
31/2-inch drive/diskette compatibility 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 Keep diskettes away from dust and dirt. Small particles of dust or dirt can scratch the magnetic surface, destroy data, and ruin the read/write heads in a diskette drive. Never wipe, brush, or try to clean diskettes in any way. Keep diskettes in a moderate environment.
Page 64: 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. If you try to change data stored on a write- protected diskette, MS-DOS displays an error message.
Page 65 On a 3 ?&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 31/2-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
Using a Single Diskette Drive System MS-DOS expects the computer to have at least two diskette drives and displays prompts and messages accordingly. Usually, MS-DOS recognizes the first diskette drive (the top drive) as A and a second diskette drive as B. If you have only one diskette drive, MS-DOS can treat it as both A and B when you need to perform operations that normally require two diskette drives.
Page 67: Inserting And Removing Diskettes
Note You can load MS-DOS from an application program diskette if that diskette contains the operating system. See your MS-DOS Reference Manual for information about creating a system diskette. Inserting and Removing Diskettes If you have a 5 1/4-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
Formatting Diskettes 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. You can also reformat previously used diskettes to store new data.
Page 70: Using A Hard Disk Drive
0 You can use the BACKUP command to back up hard disk files to diskettes. Because BACKUP can split large files across two or more diskettes, it makes more efficient use of diskette space than COPY or XCOPY. It also allows you to back up files that are larger than the capacity of your diskettes.
Page 71 Backing up the hard disk While the hard disk is very reliable, it is essential to back up your hard disk files to diskettes 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. After you create data files on the hard disk, be sure to copy them to diskettes whenever you revise them to keep your backup diskettes up-to-date.

Then type Enter press to log onto that drive. Type the following and press HDSIT You see a message on the screen that tells you the disk drive’s...
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 0 Using expanded memory beyond 0 Using the VGA utilities. Using AUTOEXEC.BAT and Other Batch Files As you get used to using MS-DOS and your application programs, you may find that there are commands you need to...
Page 74: Changing The Processor Speed
When you install MS-DOS, it creates an AUTOEXEC.BAT file for you. To modify the file or create another one, you can use the COPY or EDLIN command, or a word processing program that can save a file as a text-only file. However, be sure to name the file AUTOEXEC.BAT and store it in the root directory of the hard disk or diskette from which you load MS-DOS.
Page 75 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 76: Entering Keyboard Commands
If you frequently use programs that require the processor to operate at low speed or require the automatic speed change when your computer is accessing a diskette, use SETUP to change the processor speed. See Chapter 2 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 77: Using The Espeed Program
To enter these commands, hold down the Ctrl key and the key and press the + or - key on the numeric keypad. The speed setting remains in effect until you press the or turn off the computer, or until you change it again using the SETUP program, another keyboard command, or the ESPEED program, described below.
Page 78 The message tells you the switches you should use to set the speed to high or low. At the MS-DOS prompt, type the ESPEED command again and include the appropriate switch, such as the following: ESPEED L This command changes the processor speed to low. the current CPU speed, Enter.
Page 79: Using Expanded Memory Beyond 1Mb
Using Expanded Memory Beyond The Equity 286 PLUS comes with 1MB of random access memory. MS-DOS and your application programs that run under MS-DOS use the first 640KB of memory. If you have installed additional memory (above 1MB) in your computer, you can use it as extended memory or expanded memory, as described below.
Page 80: Modifying The Config.sys File
Modifying the CONFIG.SYS File If you have a word processing program that can save a file as a text-only file (also called an ASCII file), you can use it to add the memory manager to the CONFIG.SYS file. Follow these steps: 1.
Page 81 If you do not have a word processing program capable of saving an ASCII text file, you can modify CONFIG.SYS using the MS-DOS EDLIN or COPY CON command. See your MS-DOS Reference Manual for instructions. Using EMM286.SYS options You can include optional parameters in the DEVICE= command line to tailor the way the memory manager works with your system.
Page 82: Using The Vga Utilities
For example, to specify a page frame address 0CC000h for EMM286.SYS, add the following command line to your CONFIG.SYS file: DEVICE=EMM286.SYS /M4 Note If you have installed an EGA or VGA display adapter card, you cannot enter the following values for n: / M l - M l / M 2 - M 2 The P[nnn] option specifies the number of handles (process ID available to EMM286.SYS.
Page 83: Copying The Utility Files
The Reference diskette contains the following VGA utilities: VGAMODE SET-VGA SNOOZE Copying the Utility Files If you have a hard disk, you should copy the VGA utility files from your Reference diskette to your hard disk and run the programs from there. This section describes how to copy the files and include a pathname for the files in your AUTOEXEC.BAT file.
Page 84 the following command and press Type utility file directory on your hard disk (if you do not already have one): MKDIR C:\UTIL You can name the directory something other than UTIL; just substitute the directory name you choose in the rest of the steps in this section.
Page 85: Using Vgamode
Modifying your AUTOEXEC.BAT file For convenience in accessing your VGA utilities, you can include the pathname to the utility directory in your AUTOEXEC.BAT file. Follow these steps: At the MS-DOS command prompt in the root directory, type the following and press COPY AUTOEXEC.BAT+CON AUTOEXEC.BAT 2.
Page 86 For example, if you want your screen to display 132 columns and 25 rows, type the following and press VGAMODE 132, 25 To use VGAMODE, you must configure the application program that uses VGAMODE for the same screen sire. See the appropriate section below for your application program(s).
