Unfortunately not even the mainboard vendor BIOS changelogs are reliable. My
Asrock H97 Performance lists an BIOS update with 2.40 "Update Microcode 19."
(0x13h), however if you extract the microcode update with MMTool you get
Microcode 16. (0x10h). Exactly the same that was already included in BIOS 2.30.
In addition, I've read some guides where someone modded the vendor BIOS to
include the latest Microcode Updates (only Win, because all my Lux is currently
not working because of this old Microcode MCE :()

Has anyone tried modding an UEFI AMI BIOS directly, successfully?
