OK, then, although Stefan's meaning is pretty obvious, we can say it this
way: For those CPUs that have microcode, many can not boot successfully
without loading up to date microcode. For those CPUs that don't have
microcode, this question won't appear in the menuconfig.
Therefore, if you see this question, you have a CPU with microcode. In many
cases, if you say no, you may see troubles with your hardware. In some rare
cases the CPU can't even configure memory correctly.
I hope that's sufficiently clear?
