ASUS X99 Boards - Big Sur (Not Compatible)

[Coquin]

The motherboard I'm using is MSI X99A Godlike gaming, I think it's not much different with your SLI Plus.
I success installing Big Sur, and it works fine except sleep.
Maybe you could edit your config.plist (My system can't boot without below setting.)
Booter->Quirks->DevirtualiseMmio->True
and add MmioWhitelist to the list.

Hi

Thanks for your kind reply. But can you give me your efi or direct me to an EFI that is likely to work with my computer?

HI
Follow the way you mentioned, to fix the sleep and wake function.
I just tried it, but I can’t boot it anymore.

Sure, this is my EFI file, you can give it a try.

Hi
I tried your EFI. It boots all right and the installation works normally until there is 13 minutes left. Then it stops and I get this message:"An error loading the update". I tried to install twice and I got the same error. Any idea?

Thanks

I googled the error message and got the answer "It has run out of enough space."

Interesting and surprising because I am installing on a 500 go hard drive. I will try again after reformating the drive.

Thanks

Tested on a new SSD with same result "An error loading the update".

Thanks for your help

Hi, How can we edit boot menu icons with open core? I need to delete some icons like nvram, efi, etc. Thanks you so much.

Hi @d8833051 : could you please share your efi folder? I don't see the link. I have an MSI X99S MPower with Catalina/Clover that works without problems, but Big Sur/Opencore doesn't start.
Thank's
