Chapter 15 REVIEWING THE BASICS 1. What three OS files are necessary to boot to MS-DOS mode? What is the function of each? What additional two files are not required but are used if they are present? Io.sys (contains the basic I/O software for real mode), Msdos.sys (contains parameters and switches that affect the way the OS boots), and Command.com (contains more code to manage I/ O, programs for internal OS commands such as Copy and Dir, and a short program that looks for the Autoexec.bat file). Autoexec.bat and Config.sys are not required but are used if they are present. 2. Why is it important not to edit Autoexec.bat with word-processing software such as Microsoft Word or WordPerfect? Because word-processing programs place control characters in their documents that prevent the OS from interpreting the Autoexec.bat file correctly 3. What is the purpose of the command Device=himem.sys in the Config.sys file? To give a real-mode OS access to memory above 1 MB 4. Give two ways to access a command prompt from Windows 9x. By clicking Start, then Run, and entering command.com at the prompt, or by clicking Start, Programs, and MS-DOS prompt 5. What Windows 9x/Me program file provides a Command Prompt window? Command.com 6. What are the two wildcard characters that can be used in command lines? * and ? 7. What is the /S switch used for with the Format command? The /V switch?
