How to change boot-up delay and root password.
To change the timing of boot-up delay go to:
Edit the last line in the loader.conf file to desired delay at:
Speed up boot time autoboot_delay="02" <-- indicates delay in seconds
To change root password
During system boot-up, enter a single user mode
mount -uw /
Enter your new password for root
Now, you can login with your new root’s password
FILES /boot/defaults/loader.conf default settings -- do not change this file. /boot/loader.4th defines the commands used by loader to read and process loader.conf. /boot/loader.conf user defined settings. /boot/loader.conf.local machine-specific settings for sites with a common loader.conf.
#UEFI graphics screw up
Some Lenovo, and probably other computers with UEFI video garbage

On some systems when booted via UEFI you may end up in a console resolution that isn’t supported, resulting in a corrupt display. To work-around this issue you can do the following:
At the boot-loader menu, drop to the Command-Prompt (Under Advanced). Run the command ‘gop set 0’, replacing 0 with 1/2/3/4 until you find a resolution that seems to work with your system.
Once you’ve come up with a working resolution you can hard-code it by putting the 'gop set ’ command in /boot/loader.rc.local.
