To understand what is really going on, I did the following investigation on my only coreboot clone version, I have on my current SSD the following: WIN10, using VMware® Workstation 12 Player, version 12.5.8 build-7098237 with Fedora 26 VM, where the coreboot is located. CLI transcript follows: *[user@localhost coreboot]$ pwd* */home/user/projects/coreboot/coreboot* *[user@localhost coreboot]$ git describe* *4.5-1006-gef7e98a2ac* *[user@localhost coreboot]$ grep -r 20150121 ** *3rdparty/blobs/cpu/intel/microcode/update-microcodes.sh:MICROCODE_VERSION=20150121* *[user@localhost coreboot]$ cd 3rdparty/blobs/cpu/intel/microcode* *[user@localhost microcode]$ ls -al* *total 24* *drwxrwxr-x. 2 user user 12288 Nov 21 12:27 .* *drwxrwxr-x. 24 user user 4096 Feb 18 2017 ..* *-rwxrwxr-x. 1 user user 1782 Feb 18 2017 microcode2bin.sh* *-rwxrwxr-x. 1 user user 2989 Nov 21 12:27 update-microcodes.sh* *[user@localhost microcode]$ tail -10 update-microcodes.sh * *}* *get_microcode* *separate_microcode* *move_microcode* *dump_cpuids <<=========================== I added this line of code to see which CPUIDs's MCUs are added here: * *rm -f $MICROCODE_ARCHIVE* *rm -f $MICROCODE_FILE* *[user@localhost microcode]$ * Now, you can substitute 20150121.tgz with 20171117 <http://downloadmirror.intel.com/27337/eng/microcode-20171117.tgz>.tgz in bash shell script update-microcodes.sh and see what will happen?! I somehow hope this exercise is helpful.
