Yeah, but if you hexdump -C it, you will find both microcode cpio archives in there. lsinitramfs skips over the second one for some reason, but it is there. Furthermore, if you boot it, it ought to work, both in Intel and AMD. > Instead one cpio archive should probably created that contain > kernel/x86/microcode/AuthenticAMD.bin and > kernel/x86/microcode/GenuineIntel.bin. That would require a lot of changes to initramfs-tools. So, did you test your live-cd in both AMD and Intel boxes that would accept a microcode update? Did it work? Please do, and report back... -- Henrique Holschuh
