DOS Setup Switches

If you install Windows 98 form a DOS prompt, Setup allows several command line switches. When installing from the CD-Rom, include the switch(s) after typing in D:\Setup. Be sure to include a space in between every switch you use. Example: D:\Setup /C /IE

 /C         Instructs Setup not to load the SmartDrive disk cache
 /IL        Loads the Logitech Mouse Driver instead of the Microsoft
            Mouse Driver Use this option if you have a Logitech
            Series C mouse.
 [batch]    Specifies the name and location of the file that contains
            Setup options
 /T:TMP     Specifies the directory where Setup will copy its
            temporary files
 /IM        Skips the memory check
 /ID        Skips the disk-space check 
 /IS        Skips the ScanDisk check
 /IQ        Skips the check for crossed-linked files
 /IN        Runs Setup without the Network setup module

            to install on systems that do not meet Microsoft's minimum
 /D         Bypass usage of installed Windows configuration
 /IF        Performs quick Setup. Uses CacheFindFirst for filenames
            and speeds up DOS
