The latest bios is: ROG-STRIX-Z490-E-GAMING-ASUS-2301.ZIP
I want all HPET setting in the bios (it was already done for older bioses but links are dead: t7661f54-REQUEST-HPET-Disable-for-Asus-ROG-STRIX-Z-E-GAMING.html)
Also if there are other interesting settings to be enabled back, feel free to do it and let me know.
I will make a donation with Paypal to everyone’s gonna help me!
