At one point in time, removing 'quiet' and placing 'text' on the grub/linux command line would boot in to console mode, the current way to do that is the remove 'quiet' and add the following to the linux kernel command line:
systemctl set-default multi-user.target
I need to keep this around and see what it does to the boot up log listing (based upon Force Debian console into text mode, it can be used when ILO complains of "Monitor is in graphics mode or an unsupported text mode.":
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
Another useful function is the following to disable graphical terminal in the grub boot file (use update-grub after any changes):
GRUB_TERMINAL=console
