So, the Maximus XII Hero Wifi support page posted a bios update, 2301, and the pulled it down the next day. The description listed it as a "Windows 11" bios. I'm running the Win 11 Dev Channel latest build.
I too downloaded and flashed "ROG-MAXIMUS-XII-HERO-WIFI-ASUS-2301.ZIP" on 7/24, which looks to have been removed from the website day or two later. Didn't notice much different (compared the profile txt files and nothing new was there)
Thanks for posting. This isn't the first time they've posted a bios and immediately pulled it. Oh well, My win 11 install seems to be fast and stable for the most part. No problems with War Thunder, FS2020, Cinebench, or Prime95. All the Win 11 security features like TPM are working properly.
I just downloaded it and noticed one fairly important setting regarding Win 11 was changed from a PTT default of disabled to enable.. I was concerned that setting might mess up the TPM 2.0 requirement in Win 11..but now that is taken care of.
Just got it installed so I have not noticed any problems.
By the way, I just bounced down to the Beta channel since you can do that right now, before another Dev update comes out. That update may come out today..
