Changing Settings When the Setup program creates the SYSTEM.INI file, it assigns default values to many of the settings. Other settings have values that correspond to the type of hardware you are using. Some settings listed in this document do not normally appear in your SYSTEM.INI file. Most of these settings have a built-in default value that is present whether or not the setting appears in SYSTEM.INI. You might need to change one or more of these values to improve the performance of Windows or applications with your system. To change the values of the settings described in this document, open the SYSTEM.INI file and edit it by using a text editor, such as Windows Notepad. Do not use a formatting editor, such as a word processor in document mode; it can corrupt your SYSTEM.INI file. For more information on how to use Notepad, see Chapter 12, "Additional Accessories," in the Microsoft Windows User's Guide. Any changes you make to SYSTEM.INI settings do not take effect until you restart Windows. Caution: Do not change any settings that are not described in this document. If you need to change additional settings, refer to the Windows Resource Kit for the Microsoft Windows Operating System Version 3.1. Always back up your SYSTEM.INI file before you change any of its settings. That way, you can restore the original file if you make incorrect changes. Be careful when making changes to the SYSTEM.INI file. Your system will not work properly if you edit this file incorrectly. .
