Hi,
The last day I was lucky to have a Ryzen 3600 on hand, which I wanted to test with a compatible BIOS update. Today back on my personal AMD Ryzen 2200G, I absolutely need to return to a version 1.8 of my BIOS, but impossible: invalid file, because of this mention on the site of Asrock: “User will not be able to flash previous BIOS ounce upgrading to this BIOS version” (Https://www.asrock.com/MB/AMD/Fatal1ty%2…/index.asp#BIOS). Is it possible to modify a BIOS that I can flash (3.5) to then allow to flash a BIOS 1.8 or other? I thank you in advance.
PS : this bios can’t to be flashed : HELP disable HPET on asrock Fatalt1ty b450 Gaming k4. Bios version P1.80
