Hi and tank you for your answer.

Specifications about my motherboard are in this link: https://www.asus.com/us/Motherboards/Z97DELUXENFC_WLC/
My bios is beta version 3503 (https://www.asus.com/us/Motherboards/Z97DELUXENFC_WLC/HelpDesk_Download/)
Catalina is installed on Nvme samsung 970 evo!

Problem: after the first restart, from opencore i select the "installbigsur.dmg", the apple logo appears and it restarts again after a few seconds unfortunately.

 

[furion3000]

link guide to mod bios

ASUS Maximus VII Z97 Hero Big Sur Open Core Guide

I've written some detailed guide in my time but I'm going to keep this one shorter. I want to accomplish 2 things with this write up.1. Address the native nvram problem, this is huge for people with similar hardware moving forward with Big Sur.2. Help others get installed and booted with a very c...

I modified your bios file, but if you want to do it, I will send you the link to do it yourself. use the driver nramsmiok that I gave you those dell asus z97 deluxe do not work.

for install bios use afudos and pendriver

now clone you system in SSD samsung evo 870 use (carbonclone or superdump) and disconnet nvme card and haddriver and pci tunderbirth.

after installation on the ssd and verified that everything works, clone everything again on the samsung evo 970 Nvme


for updating the bios, I take no responsibility. in case of block it takes an eeprom programmer to reinstall the bios or if it is not corrupt just insert a pen with the original bios in the appropriate USB port. and when the pc starts the update starts.

Perfect!

I had already read the guide that you linked to me but I had concluded little and nothing unfortunately.

Perfect I'll try the bios you edited for me on Thursday morning!
But what is the Nvramsmiok file for? and how should i use it?
Ps but you speak Italian

the file Nvramsmiok is the driver to replace in your bios. this driver work for asus z97 deluxe. in uefi tools use this file to replace body in bios and save bios in rom extension. after open mmtool and load bios.rom and search mvram line . click extrac , now in mmtool open original bios .cap and load extrac file select line to nvram ad click replace , now save image as . bios2.rom ok now upgrade bios to afudos. if you not upgrade bios big sur not update. or is the nvram driver is not work the problem does not change. until in my card, I did not find the right driver I always had the same restart problem. what i sent you is the driver that works on mine and yours.

Hi! Your bios modded perfectly worked in my motherboard.
I tried to upgrade but it was unsuccessful. I disconnected the bluetooth and wifi pciex peripherals and connected only one monitor. During the load it goes into kernel panik as usual and reboots.
In your opinion, is it possible to perform a clean installation on big sur ssd now that I have also modified the bios?

do not add more kext as it goes into kernel panic. use my kext and in the bios you have configure bios after update bios . in the boot verbose mode, writes "device is write locked" ? remove the samsung 970 evo disk. install on ssd, unplug all sata devices, leave only sata ssd disk . if it is written "device is write locked", the NvramSMI driver has not been placed correctly in the bios.
