Well… a mod bios IS NOT an official bios file and unpredictable results may happen to the motherboard… including a “death” system or you really dont understand nothing of this?
Only a user that has done the same mod, flashed it and can share it with you, can give you a more reliable change of everything works as intended.
The issue here is not the mod, its a user that doesnt understand this and can get a bricked motherboard due to a forum shared file and blames the forum or the user.
