AIUI, when the machine boots, the BIOS loads the CPU microcode on
machine startup *before* Linux (or any other OS for that matter) boot
processes take over.  That is, every time the machine is booted, from
cold at least, the CPU microcode is updated from an area within the BIOS
.

If you have a newer microcode, then that /might/ be applied at the OS
level at some point.

Cheers
A.
