I see, I used a converter to connect the VGA monitor to the Intel HDMI port and it worked, but the resolution between the two monitors connected to the Intel HD 4600 was shared, every time I changed it on one monitor the other one would also switch. I'll look into connecting all displays to the GTX, thank you!

I have full acceleration with my GTX770 which is hooked up to two monitors, perfect! I've also got two additional monitors which are hooked up to my onboard video, HD 4600, but on that onboard video just one of the monitors will work, I attached some screenshots. Is there any tweak to get the second monitor connected to the HD 4600 to work as well?

Thanks a lot Maldon, worked like a charm, as always you're the best ?

Not sure what else to do since the kext seems to be loaded into memory, what am I missing here to get it to work? I would appreciate any tips!

Btw I just booted catalina and installed it fresh no problem at all, the installation reboots but I can continue by booting from the harddrive install program and it will complete successfully, with big sur the problem is that it reboots forever

No luck so far man, I have tried many EFI folder combinations from other users with simila hardware, 4th gen haswell + GT7xx but it keeps rebooting during install and fails to resume the installation.

Yes, there is a preboot from the hard drive I installed it on, "OSX", and when I choose that option it starts loading as usual and reboots with the messages above. I'm really lost here since OC had the same issue, on clover I'm using your EFI folder which worked perfectly on Mojave and Catalina. Any help is much appreciated.

I had a similar issue with OC which I was never able to fix, now I'm trying Clover with the EFI chipset folder you prepared for us, in my case the Haswell one. I can boot Clover and start the installation no problem at all, around 12 minutes the installation will reboot the pc, then I can boot into the setup from Clover again, either from the USB EFI or from the hard drive which I installed big sur, cause now it will show up under Clover as a boot option (install preboot). Problem is I did resume it about 5 times and it always reboots after the console is gone and the apple logo starts loading. Can you help me out?

Question, when it reboots the reboot is like the one in the video, a cold reboot out of nothing? Cause when it reboots OC gives me an option to boot the installer directly however the installer does not continue, it starts all over...

My installation has been rebooting around 13 minutes, how can I find out what's wrong with it? I made a few videos with the reboot happening: config (2).zip

Thanks for the heads up, when you say try combinations you mean to really play with the config settings from other boards/systems that worked for other people until it boots right?

Hi Maldon! I followed that guide, copying over my chipset files to the USB EFI folder (mounted with OC Configurator), which happens to be H97 so "EFIOpenCore Serie 9", replacing all the existing files in the USB EFI folder. Unfortunately it keeps freezing at the same error. I went as far as of validating my configuration (see attached) at https://opencore.slowgeek.com and did minor adjustments, yet freezes on that screen. How can I find out more about the error, like the specific reason? Thank you config.zip

I used to have Mojave and Catalina working perfectly, today I download the BigSur from the torrent link and when boot it up it keeps freezing at "LOG:EXITBS:START", checked my BIOS and didn't find any odd settings, it's the usual stuff that worked on Catalina, what can I do about this error? Thank you

Actually I don't remember trying... but I was able to install Mojave no problem, then i went on the bios and disabled CSM + deleted all UEFI keys, tried Catalina installation again and it worked. Thank you.
