Not quite: end user is dependent on the OEM to get a BIOS update. What is meant with early loading in this context is, to put the microcode in the initrd so that it gets loaded very early during the *kernel* boot. And early-initrd-based loading is the default method we do microcode loading with, anyway. So the blacklisting is only for *late* loading, through the sysfs trigger. Which is only there for historical reasons and for some configurations. -- Regards/Gruss, Boris. ECO tip #101: Trim your mails when you reply. --
