Putting in the Windows

Putting in the Windows

You should understand the steps that are used to install each version of Windows and the procedures that are used to upgrade from one version to the next. Practice installing as many of the Windows versions as you can. However, if you lack all the various versions, concentrate on installing Windows 98 and work on upgrading it to either Windows 2000 Pro or Windows XP Pro.

First, some DOS facts

You’ll encounter some DOS commands, files, and features on the exam. Although you may not be asked directly about the DOS operating system itself, you need to know the files and commands that are still in use by Windows and those that come in handy to diagnose certain software-related problems.

 Remember  You should know something about the following DOS/Windows files, commands, and terms for the OS Technologies exam:

  • CONFIG.SYS is not required for DOS or Windows to start up.

  • COMMAND.COM displays the DOS command prompt, contains the internal DOS commands, and is required for DOS and Windows 3.x to boot.

  • EMM386.EXE enables expanded memory and allows the use of upper memory as system memory.

  •  Instant Answer  The boot sequence for a DOS system is IO.SYS, MSDOS.SYS, CONFIG.SYS, COMMAND.COM, and AUTOEXEC.BAT. To boot to a DOS command prompt, only IO.SYS, MSDOS.SYS, and COMMAND.COM are required to load.

  • DOS memory is divided into three areas:

    • Conventional memory (640K)

    • Expanded or upper memory (384K)

    • Extended memory (above 1024K)

According to the A+ OS Technologies exam objectives, you need to know the following MS-DOS commands and terms:

  • CD: Change the current directory.

  • DEL: The DEL (Delete) command allows you to remove one or more files or folders from permanent storage, such as a disk.

  • DELTREE: The DELTREE command can be used to delete a directory or folder and all its subdirectories or subfolders.

  • ECHO: This command turns the display or commands in a batch file on or off, and it can be used in a batch file to display a message.

  • EDIT: This command opens a text-editor utility that can be used to create new files or modify existing files.

  • FDISK: Together with the FORMAT command, the FDISK command is one of the most important DOS commands that is still in use. FDISK is used to create and manage primary, extended, and logical partitions on a hard drive.

  • FORMAT: When you are getting ready to install an operating system, the disk partition on which you are installing the system must be made ready for use by running the FORMAT command on it. Disk media must be formatted before it can be written to or read by the PC.

  • MD: Create (make) a new directory.

  • MEM: This command displays the amount of memory that is installed and the amount that is available in conventional, extended, expanded, and upper memory areas.

  • RD: Remove an existing directory.

  • REN: This command is used to rename a file or directory. You must conform to the 8.3 naming convention of MS-DOS when using this command. (The 8.3 naming convention refers to a filename in which the prefix does not exceed 8 characters and the suffix does not exceed 3 characters.)

  • SET: This command is used to insert a string value into a command variable that can be accessed later by another program or batch file.

  • SETVER: This command displays the version of the running version of MS-DOS and allows the running version to be set to that needed by real-mode programs.

  • TYPE: This command displays the contents of a file on the display.

  • VER: This command reports the running version of MS-DOS, which may not be the installed version of MS-DOS.
