Sorry for the question, this is not exactly the right place but I know of no better one: Do microcode updates delivered by this package have the same effect as BIOS/Firmware updates? Or do they complement each other? At our organization, we unfortunately have a large number of different machines from different vendors, and updating the BIOS on all of them will be a very time consuming task. So I'd like to ask whether we can expect the same protection from updated microcode and kernel packages. Thanks, Andreas
