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 avoiding 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).
