A feature in DOS 6.0+ supports multiple configuration sets. You can
display a menu of options and, depending upon the selection, execute
different parts of CONFIG.SYS and AUTOEXEC.BAT.
─────────────────────────────────── Menu Definition Commands
[MENU] Identify the beginning of the startup menu.
MENUITEM= Define text to display in a menu and identify a block of
commands to be executed when that option is selected.
MENUDEFAULT= Set a default option and a time-out value.
MENUCOLOR= Set text and background colors for the menu display.
SUBMENU= Identify a menu item as a submenu.
─────────────────────────────────────────── Related Commands
INCLUDE= Execute the commands in another block and resume executing
the commands in the current block.
NUMLOCK= Set the initial state of keyboard NumLock. This
facilitates using the arrow keys for making a selection.
SET Create an environment variable for possible use in
AUTOEXEC.BAT or other batch files.
SWITCHES= The /N switch disables F8 (Interactive Boot) and F5
(Clean Boot). /F tells DOS to skip the normal 2-second
delay before starting to execute CONFIG.SYS.
──────────────────────────────────────────── Syntax Elements
[COMMON] Identify a series of commands that will be executed
regardless of which configuration menu option is chosen
(Note: Commands above the first menu are considered to be
part of a [COMMON] block).
[blockName] Identify the beginning of a series of CONFIG.SYS commands
or the start of a submenu.
CONFIG An environment variable that gets set to the blockName of
the selected menu item. Use this to run specific commands
in AUTOEXEC.BAT, depending upon the chosen configuration.
REM or ; Lines beginning with a semicolon (;) or REM are ignored.
cmd?= A question mark (?) before the equal sign (=) sign in any
CONFIG.SYS command causes DOS to prompt and allow you to
skip that command.
