SUMMARY
=======

This article lists the command-line switches for Win.com. Win.com is called by
Io.sys after the Autoexec.bat file is processed, and starts the Windows 95/98
startup process.

MORE INFORMATION
================

The syntax for Win.com is:

  WIN {/D:[F] [M] [N] [S] [V] [X]} [/W] [/WX]

The command-line switches for Win.com are described below:

  /W  Restores the Config.sys and Autoexec.bat files from Config.wos
      and Autoexec.wos and prompts:

         Press any key to continue...
         Pressing a key reboots the system back to Windows 95/98.

  /WX Restores the Config.sys and Autoexec.bat files from Config.wos
      and Autoexec.wos and reboots the system to Windows 95/98.

      NOTE: .wos files are created when you open a program requiring
      MS-DOS mode and you have specified a new MS-DOS-mode
      configuration. You might need to use the /W or /WX switch if you
      shut off your computer while you are running an MS-DOS-based
      program that requires MS-DOS mode and you want to return to
      Windows 95/98.

  /D: Used for troubleshooting when Windows 95/98 does not start
      correctly. This switch is used with the following switches:

      F  Turns off 32-bit disk access. This is equivalent to
         "32BitDiskAccess=false" in the System.ini file.

      M  Enables Safe mode. This is automatically enabled during a
         Safe-mode boot (by pressing F5).

      N  Enables Safe mode with networking. This is automatically
         enabled during a Safe-mode boot (by pressing F6).

      S  Specifies that Windows 95/98 should not use ROM address space
         between F000:0000 and 1 MB for a break point. This is
         equivalent to the "SystemROMBreakPoint=false" setting in the
         [386Enh] section of the System.ini file.

      V  Specifies that the ROM routine handles interrupts from the
         hard disk controller. This is equivalent to the
         "VirtualHDIRQ=false" setting in the System.ini file.

      X  Excludes all of the adapter area from the range of memory that
         Windows 95/98 scans to find unused space. This is equivalent to
         the "EMMExclude=A000-FFFF" setting in the System.ini file.

  NOTE: The following /D: parameters do not work in Windows 98:

   - /D:FSVXN
   - /D:N
