Specifies the default menu item on the startup menu and sets a timeout value
if desired. You can use this command only within a menu block in your
CONFIG.SYS file. If you do not use this command, MS-DOS sets the default to
The startup menu is a list of choices that appears when you start your
computer. You define a startup menu by using special CONFIG.SYS commands.
Each item on the menu corresponds to a set of CONFIG.SYS commands called a
"configuration block." A startup menu makes it possible to start your
computer with a variety of configurations. For more information about
defining multiple configurations, see the chapter "Configuring Your System"
in the MS-DOS User's Guide.
Specifies the default menu item by its associated configuration block.
The block must be defined elsewhere in the CONFIG.SYS file. When MS-DOS
displays the startup menu, the default menu item is highlighted and its
number appears after the "Enter a choice" prompt.
Determines how many seconds MS-DOS waits before starting the computer
with the default configuration. If you don't specify a timeout value,
MS-DOS does not continue until the ENTER key is pressed. You can specify
a timeout value from 0 to 90 seconds. A timeout of 0 forces automatic
selection of the default, effectively bypassing the menu display.
The MENUDEFAULT command is one of six special CONFIG.SYS commands for
defining startup menus and multiple configurations. The other commands are
* The <MENUITEM> command, which defines an item on the menu.
* The <MENUCOLOR> command, which defines the color of the menu's text and
* The <SUBMENU> command, which defines a submenu.
* The <NUMLOCK> command, which specifies the state of the NUM LOCK key when
the startup menu appears. (Although NUMLOCK can be used anywhere in the
CONFIG.SYS file, it is especially useful when defining a startup menu.)
* The <INCLUDE> command, which includes the contents of one configuration
block in another. This command cannot be included in a menu block.
