MENUDEFAULT--Example

The following menu block defines three menu items, sets the default item to 
"full_config," and sets the timeout to 30 seconds:

    [menu]
    menuitem=base_config,Base configuration only
    menuitem=full_config,Normal configuration
    menuitem=network,Normal configuration with network
    menudefault=full_config,30

When MS-DOS starts and reads this menu block, it displays the following
menu:

    MS-DOS Startup Menu
    ===================

       1. Base configuration only
       2. Normal configuration
       3. Normal configuration with network

    Enter a choice: 2                       Time remaining: 30

After displaying this menu, MS-DOS waits 30 seconds; if no other item is
selected, MS-DOS then starts the computer using the commands in the
[full_config] configuration block.
