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.

Some people have asked us whether this is safe to use or not. You will be booting using this USB drive as a shortcut before Windows. It's also important that you know how to backup or restore your BIOS, just in case. For that, be sure to read How to Reset Your BIOS to Optimal, Default or Factory Settings.
