First, check to see that you might already have the needed bios level.
Motherboards are made with the latest bios already applied.
You can see the bios level on your bios screen, or cpu-Z will tell you what you have.
Many motherboards have a method to update the bios via the internet.
Read your motherboard manual.
I would NOT try that.
If you have an internet outage during the process you can have problems.
A failed bios update can be difficult to recover from.
A minimal flash drive is only a few bucks anywhere.
Download the bios file and copy it to a
fat 32 formatted usb drive.
A flash takes a while with nothing apparent going on.
Do not interrupt the process.
It might take 15 minutes or longer.
