NOTE: In order to not fully abandon machines affected by AMD-SB-7033 [1] that
have not received the BIOS update, the family 19h microcode container now
includes a second patch for these machines that brings the microcode to the
highest possible level without the microcode signing fix. While a BIOS update
is highly recommended to receive the latest security updates issued after the
microcode signing vulnerability, this will allow non-updated systems to at
least receive some microcode updates beyond the version provided by BIOS.
