ASUS X99 Boards - Big Sur (Not Compatible)

[RooteDady]

This is my latest bios of x99 deluxe II, in which nvram and msr are patched, and both verify that it works normally. But in the process of upgrading bigsur, I also restarted in the second stage, unable to complete the installation. This is my bios.

Can I see your EFI folder? Maybe I can help.

Try it

Try it

Unfortunately, it still has the same effect. I guess it is the same as the problem in the link you gave me. I need to use the debug version of oc to determine the address of vnram, and then add this information to the plist file. Thank you!

You can try this EFI.
When you first boot with it, Use the CleanNVRam tool.
Then, start installing Or upgrading
Good luck.

Hello there! This time the effect is the same, but in the second stage, the mouse on the screen can be moved, but it still cannot escape the fate of restarting... Thank you very much!

I tried your startup configuration, but still the same effect. In the second stage restart, I also used the method of adding nvram path, or restarted in the second stage. Is there anyone who succeeded in x99 deluxe II? I have seen a lot of ASUS X99-A which is a native and effective motherboard with nvram.

I used PRELIMINARY METHOD FOR INSTALLING BIG SUR ON SYSTEM WITH BROKEN NVRAM successfully and Everything is working but i got black screen wake from sleep. I tried to patch SSD-VEGA64.aml for my graphic card. Unfortunately I failed and needs someone's help. Thanks
