SWITCHES--Notes

When to use the SWITCHES command with an enhanced keyboard

If you have a program that does not correctly interpret input from an
enhanced keyboard, add this command to your CONFIG.SYS file so your enhanced
keyboard will use conventional keyboard functions.

Using the /K switch with ANSI.SYS

If you use the SWITCHES=/K command and you install the ANSI.SYS device
driver, use the /K switch on the DEVICE command line for ANSI.SYS.

The SWITCHES command and the DRVSPACE /SWITCHES command

The SWITCHES /N and SWITCHES /F commands affect the behavior of the F5 and
F8 keys when your computer starts. To control the behavior of the CTRL+F5
and CTRL+F8 startup keys, which bypass DriveSpace in addition to other
startup commands, use the <DRVSPACE /SWITCHES>command.

Using the SWITCHES command with Microsoft Windows 3.0

In order for Microsoft Windows 3.0 to run in enhanced mode, the WINA20.386
file must be located in your root directory. If this file is not present,
you will see this message:

    You must have the file WINA20.386 in the root of your boot drive
    to run Windows in Enhanced Mode

If you move the WINA20.386 file, you must add the SWITCHES command with the
/W switch to your CONFIG.SYS file. You must also add a DEVICE command under
the [386Enh] heading in your SYSTEM.INI file, specifying the new location of
the WINA20.386 file.

If you do not use Microsoft Windows version 3.0, do not use the SWITCHES
command with the /W switch.
