Type: Internal (6.0 and later)
Syntax:
MENUDEFAULT=blockname, [timeout]
Purpose: Used in the CONFIG.SYS file to set the startup
configuration
that will be used by DOS if no key is pressed within the specified
timeout period.
Discussion
You can only use one MENUDEFAULT= line within a menu block in your
CONFIG.SYS
file. The default menu option that you specify with the MENUDEFAULT
command will
only be executed if you do not select another option within the specified
timeout period. You can also stop the timeout count by pressing any key
on the
keyboard during the timeout period. Then you can select an alternative
option
by using the arrow keys to move the highlight from one option to the
next, or by
entering the line number of the option you want to execute.
For more information about the MENUDEFAULT command, see Chapter 6, Tips for Advanced Users, in the downloadable book DOS the Easy Way.
Options
blockname - Specifies the menu line that DOS will highlight when the
menu is displayed.
timeout - Specifies the number of seconds (0 to 90) that DOS will
wait before starting the system using the default menu option, if no other
option is selected. If 0 is used, the specified option will immediately be
executed.
Example
If you want to create a menu in your CONFIG.SYS file that provides a
number of
configuration options upon system startup, any one of the menuitems could
serve
as the default menu option that will be activated if no option is
chosen. The
following example designates the menu option named NORMAL as the default
option:
menudefault=normal, 30
DOS will automatically select the NORMAL option after 30 seconds.
