Intel Microcode Boot Loader is designed to patch legacy motherboards that weren't updated to protect against security vulnerabilities including Spectre, for example.
Instructions: 1. Format a USB flash drive with a FAT32 filesystem. 2. Extract the archive to the USB flash drive and run install.exe to make it bootable. 3. Enter the BIOS/UEFI, assign the USB flash drive as the 1st boot device and enable legacy boot mode. 4. The bootloader will regularly update the microcode and load the OS.
Notes: * This release includes the latest ucodes for 392 Intel CPUs produced from 1996 to 2018. * The ucodes are stored in the \boot\mcudb folder if you wish to update in the future. * If you get 'Ucode not found' warning during installation, or plan to deploy on another PC, look for the correct ucode (by CPUID) in \boot\mcudb and copy it to \boot\mcu.
