By default FreeBSD sets a ten second delay during the boot process allowing the user to select alternate boot options.  Options such as single user mode, recovery, etc.  If you’d like to change this boot delay to something more reasonable you can add the following to your /boot/loader.conf:

autoboot_delay=X

I’ve set mine to two seconds (autoboot_delay=2) as I feel that is reasonable to give me time if I need it, but not sit and count down if I don’t.  If you’d like to bypass this menu altogether you can set the value to “-1”.
