You can also verify the presence of the files in the initramfs image: wooledg:~$ lsinitramfs /boot/initrd.img-4.19.0-6-amd64 | head kernel kernel/x86 kernel/x86/microcode kernel/x86/microcode/.enuineIntel.align.0123456789abc kernel/x86/microcode/GenuineIntel.bin . bin conf conf/arch.conf conf/conf.d
