The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

               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.
