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. This sect[...]

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. The figure below provides a simple representation of tr[...]

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. Because data is stored magnet[...]

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 [...]

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 [...]

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 har[...]

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. To write[...]

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. -write-protect switch To remove the write protection, slide the switch[...]

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 perf[...]

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 labe[...]

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; then press the release button. When the disk[...]

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. This process erases all[...]

Using a Hard Disk Drive Using a hard disk is similar to using a diskette. However, the hard disk provides several advantages: cl D Cl 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. Your computer can perform all disk-rela[...]

Caring for your hard disk drive Follow these precautions to protect your hard disk drive from damage and to avoid losing data: Never turn off or reset the computer when the hard disk access light is on. This light indicates that the computer is copying data to or from the hard disk. If you interrupt this process, you can lose data. Never attempt to[...]

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. You are now ready to move it to the new location. Note For convenience, you may[...]

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. BAT and Other Batch Files As you get used to using MS-DOS an[...]

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. However, be sure to name the file AUTOEXEC.BAT and store it in the root directory of the hard disk or diskette[...]

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: 0 0 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. If this works, you do not n[...]

Using Expanded Memory Beyond 640KB The Equity 320sx PLUS comes with 2MB of random access memory. MS-DOS and your application programs that run under MS-DOS use the first 640KB of memory. You can use any memory above 1MB as extended memory (up to 16MB) or expanded memory (up to 24MB). Shadow RAM uses 128KB of the RAM available between 640KB and 1MB [...]

3. Add a command to the CONFIG.SYS file to include the memory manager as a device driver, as described in the next section. The CONFIG.SYS file is used by MS-DOS to set up the computer’s system configuration requirements. 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 A[...]

3. Save the file as an ASCII text file. 4. Reset the computer. 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, or a text editor. See your MS-DOS manuals for instructions. Using EMM386SXSYS options You can include optional parameters in the DEVIC[...]

The M[n] parameter specifies a particular 64KB page frame address for EMM386SX.SYS. The value n must be a number from 1 to 9 to indicate one of the following addresses: l Default setting For example, to specity a page frame address of 0CC000h, add the following command line to your CONFIG.SYS file: DEVICE-EMM386SX.SYS /M4 Note If you have installed[...]

EMM386SX.SYS automatically excludes from mapping any addresses that are reserved for use by your system ROM and RAM. If you install an option card, such as a network card, that uses the memory address range C000 through E000, include the X parameter in the DEVICE= command line to exclude this memory range from expanded memory mapping.
