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 Additional query words: 98
