Commands for Defining Multiple Configurations

A single CONFIG.SYS file can define several different system configurations.
To define multiple configurations, you use the following special CONFIG.SYS
commands:

<Include>
<Menucolor>
<Menudefault>
<Menuitem>
<Submenu>

To define multiple configurations, follow these general steps:

1  Define a startup menu in the CONFIG.SYS file by using a [menu] header
   followed by one or more <MENUITEM> commands. The <MENUDEFAULT>,
   <MENUCOLOR> and <SUBMENU> commands can be used to define special
   characteristics of the startup menu.

2  Create a configuration block in the CONFIG.SYS file for each
   configuration you want. A configuration block begins with a block header
   -- a name surrounded by square brackets. To each block, add the
   <CONFIG.SYS commands> that you want MS-DOS to carry out when that
   configuration is selected from the startup menu.

3  (Optional) In the AUTOEXEC.BAT file, use <batch commands> such as <GOTO>
   and <IF> to have MS-DOS carry out different AUTOEXEC.BAT commands
   depending on the startup configuration.

   When a configuration is selected from the startup menu, MS-DOS defines an
   environment variable named CONFIG and sets it to the name of the selected
   configuration block. To have MS-DOS carry out different sets of commands
   for different CONFIG values, add a GOTO %CONFIG% command to your
   AUTOEXEC.BAT file.

For more information about defining multiple configurations, see the chapter
"Configuring Your System" in the MS-DOS User's Guide.
