It is still used in some Linux distributions. It can be updated to the system through the old microcode update interface which is available in the kernel with CONFIG_MICROCODE_OLD_INTERFACE=y. To update the microcode.dat to the system, one need: 1. Ensure the existence of /dev/cpu/microcode 2. Write microcode.dat to the file, e.g. dd if=microcode.dat of=/dev/cpu/microcode bs=1M intel-ucode directory contains binary microcode files named in family-model-stepping pattern. The file is supported in most modern Linux distributions. It's generally located in the /lib/firmware directory, and can be updated through the microcode reload interface. To update the intel-ucode package to the system, one need: 1. Ensure the existence of /sys/devices/system/cpu/microcode/reload 2. Copy intel-ucode directory to /lib/firmware, overwrite the files in /lib/firmware/intel-ucode/ 3. Write the reload interface to 1 to reload the microcode files, e.g. echo 1 > /sys/devices/system/cpu/microcode/reload

Love it.
However, %%DATADIR%%/mef406f1_0b000021.fw is listed there, but I have a 2a version in my tree from Intel. Can you confirm that this is the latest version in what's released? The 2a version may be pre-release still.
Otherwise, all the files I care about for $WORK match the latest that we have.

Took a look at the microcode.dat file in the tgz from intel. The preamble/header appears to be the same.
