Intel Microcode Boot Loader 0.5.4

Beginning of the year 2018, the security researcher has discovered several security holes affect all processor: Meltdown and the Spectre. This vulnerability allows for performing attacks side channels perform speculative (CVE-2017-5715, CVE-2017-5753, CVE-2017-5754). While the Meltdown has been resolved by a patch to the operating system, Spectre requires updates en code. Because microcode is stored and automatically loaded by the BIOS / UEFI, should the manufacturer of the motherboard to release updates. However, the manufacturers usually release firmware updates only for the latest products of them. Many motherboard still vulnerable until today.

Intel Microcode Boot Loader

Intel Microcode Boot Loader is a solution to the problem of micro-code on the motherboard based on the Intel. It updates the microcode each time the system is booted. Based on The test deployment BIOS (BITS) of Intel, users no longer need to modify the ROM BIOS / UEFI to be protected from security vulnerabilities, bugs and errors.

This solution requires a USB flash drive is plugged permanently with at least 25 MB (or similar device) and boot support BIOS / UEFI from the USB device. In addition, advanced users can install it on local disk on the first partition System Reserved (see localdrive.txt to know instructions).

Instructions:

1. Format the USB flash drive with FAT32 file system.

2. Unzip the archive file into the USB flash drive and run install.exe to make it bootable.

3. Enter BIOS / UEFI, specify the USB flash drive do boot device number 1 and turn on the mode old boot.

4. The boot loader will regularly update micro code and load the OS.
