Not sure what you are asking for. The downloads for your processor are here:
Or, are you asking about a firmware/bios update for the motherboard?
Or, are you asking about updates for Spectre and Meltdown?
Thanks for your response, I was looking for the ME firmware versión
That should be available from your motherboard manufacturer.
In many cases, the BIOS will have a place in its Setup facility where it displays the version of the ME F/W that is running.
