Update BIOS and Unlock Better Performance

English | 中文

Introduction

The BIOS packet in XMAKB5R0P0906 folder is from Xiaomi stuff, so it is reliable. This pack is only compatible with MX150 version.

The ME firmware in ME folder is from Fernando's Win-RAID Forum. Using the latest ME firmware helps to avoid potential malicious attack. The ME firmware version in the folder is Intel CSME 11.8 Consumer PCH-LP Firmware v11.8.55.3510 and the version of Intel (CS)ME System Tools is Intel CSME System Tools v11 r14 - (2018-08-09).

Warning: Since the operations are related to BIOS, it's possible that if some errors(such as force quit the update program) occur during the update process(so as to scripts in #8), the whole system may unable to boot.

If unfortunately, this situation happens on you, you need to find Xiaomi stuff to fix your device. If you use this program, you should agree that you are the person who takes the whole responsibility, instead of the author.
