Hi,
hey that's great!. Yes I think 1801 is the latest.
Ok, first pop back into the bios and look for a setting called 'apply optimised defaults'. This will set the bios with the basic safe settings for your machine. Save config and reboot back into bios.
Once you've applied the optimised defaults you can then go through the bios setting the correct parameters for things like the date/time, Boot order, RAM speed (if it's above 1333mhz) and anything else like turning off splash screens (something I always do). Your CPU should be set up and their should be no need to change anything at this time.
Remember if your running an SSD make sure the storage controller is set to AHCI mode.
Once you've done that please post back.
