Compatibility: 6.0+
Purpose: Chooses a default selection in a MultiConfig Menu and sets a
time-out value to let the boot process continue setting up a
default configuration.

Uses:   Set up so that a MultiConfig CONFIG.SYS file can run its course
automatically, without user intervention.
  Position the menu cursor so that one press of Enter will
continue with the most-often used configuration.
  Skip the "MS-DOS Startup Menu" display altogether.

Syntax: MENUDEFAULT=blockName [,time-out]

  Parameters  

blockName is the name of a block of CONFIG.SYS commands.  It must be one of
the blocks named in a MENUITEM= or SUBMENU= command in the same
menu block.

[blockName] (the same text, enclosed in square brackets, on a
line by itself) must appear elsewhere in the CONFIG.SYS file.

time-out specifies a delay interval, in seconds.  DOS will wait time-out
seconds and if it senses no keystrokes, it exits the menu and
executes the commands in the block identified by blockName.

If time-out is omitted, DOS will display the menu and pause until
Enter is pressed.

The time-out value can range from 0 to 90 seconds.  A value of 0
causes DOS to bypass the menu and immediately execute the
commands in the blockName block.

  TECH Notes  

  An invalid syntax such as...

MENUDEFAULT no_ems No EMS, 10

...will cause DOS to try to evaluate "NO EMS" as a time-out number and
it comes out as 0.  The result is that execution immediately begins at
blockName.
