-Intel BIOS packages also include the latest microcode for the CPU upon release of the BIOS package. Usually you will get the microcode first in the microcode package mentioned in 2)and once the next BIOS is released after the microcode update has been released, the BIOS update should include the Microcode package as well. Because Linux only loads the microcode from its own package when it's newer than the version loaded by the bios, a BOIS upddate that gets you the new Microcode will work even with old Linux Versions that might be out of maintenance. However, if you are using such a Distro, you probably aren't worried too much about security anyway and your system is hopefully only running in a well protected internal network with trusted users.. in that case, don't worry about Meltdown :) +BIOS packages from the mainboard vendor should also include the latest microcode for the CPU upon release of the BIOS package. sometimes you can get microcode updates earlier through a BIOS update than you can get them through the intel microcode package download. Howeverif your mainboard producer supplies no mor BIOS updates or if they have a slow release cycle, the intel package might be the faster solution for you.

 If you do worry about meltdown and want to upgrade the microcode through a new bios, you can find a list of the latest BIOS releases that contain Variant 2 fixes in their included microcode on this [[https://www.intel.com/content/www/us/en/support/articles/000026622/server-products.html|Intel-SA-00088 for Intel® Server Boards]] overview page. The list is updated as soon as new bioses become available.  If you do worry about meltdown and want to upgrade the microcode through a new bios, you can find a list of the latest BIOS releases that contain Variant 2 fixes in their included microcode on this [[https://www.intel.com/content/www/us/en/support/articles/000026622/server-products.html|Intel-SA-00088 for Intel® Server Boards]] overview page.
