Managing System Startup File - SYSTEM.INI
This section describes the system startup file, SYSTEM.INI, and how to change it with the system configuration tool 'msconfig.exe'.
SYSTEM.INI was a basic startup file used in early versions of Microsoft Windows to load device drivers and the default Windows shell (Program Manager or Windows Explorer). Many of these settings were honored in Windows 9x, although the files had begun to be phased out in favor of the Windows registry. Windows XP still acknowledges some entries in the SYSTEM.INI file, to provide backwards compatibility with older 16-bit applications.
SYSTEM.INI file is located in the C:\SYSTEMS directory. Here is the content of SYSTEM.INI on my Windows XP system:
C:\herong\type C:\windows\system.ini ; for 16-bit app support [drivers] wave=mmdrv.dll timer=timer.drv [mci] [driver32] [386enh] woafont=dosapp.FON EGA80WOA.FON=EGA80WOA.FON EGA40WOA.FON=EGA40WOA.FON CGA80WOA.FON=CGA80WOA.FON CGA40WOA.FON=CGA40WOA.FON
If you run "msconfig.exe" and click the SYSTEM.INI tab, you will see that all settings
in system.ini are presented with checkboxes for you to turn on or off:
