Linux Fixes Issue Where Applying AMD Zen1/Zen2 Microcode Updates Could Slow Boot Times

[Anux]

My BIOS has a "save user settings" option and those survive a bios flash/reset, I can just load them afterwards. Only my fan curve isn't saved

You can attempt a genius move like save the uefi settings, write them to the usb where your bios image is and after update reload the settings, well if it works is another matter .....

Did you read my message? "Even if I can save current settings to a file on a USB drive, I cannot restore settings from the file because de UEFI version is different."
I own a MSI B450M MORTAR MAX, and I already tried, but the UEFI refuses to load the configuration file because of version mismatch, which is why it is so annoying.
I think this limitation is present only on a MSI motherboard, maybe I will switch to a different brand next time I need to buy a new motherboard.
