Success: Catalina on ASUS ROG Strix H370-I Gaming

[jcdufourd]

Here are my BIOS settings

 

[jcdufourd]

I have had the following experience with motherboard firmware:
- I was using firmware 1404 and had a few problems
- I updated the firmware to the latest, 2811, without any precautions
- suddenly my clover/catalina was not recognised, my brand new opencore/catalina failed, ubuntu dual boot failed as did any boot from USB (ubuntu, clover, opencore)
- I wanted to go back to firmware 1404 after many attempts to diagnose the problem and many changes to the BIOS settings, but firmware 1404 was corrupted on the ASUS website.
- I tried all available firmware versions and only the last three were usable: I downgraded to the oldest firmware that works, i.e. 2401
- clover/catalina still fails
- ubuntu and opencore/catalina work again

Conclusion: never upgrade your firmware if you have a working configuration that you care about...

Very interesting account of your experience with the Rog H370 I Gaming.

I had just finished my third build - a 'Mac Mini' based on a Gigabyte B360N.... (EVGA Z390 / Asus Prime Z270 being the others - both Opencore).

Almost everything worked on the B360N but I wasn't happy with UHD and the way I was getting black screens on one of the the 4K UHD TV inputs which requires a 60Hz input.

So I decided to change the MB to the Rog H370 as it has a DP / 60Hz. Spent all day trying to get it past Verbose - and I'm talking about the rig restarting ....not even a black screen ....now I know why! Like you I had upgraded to bios 2811 so thanks so much for the heads up.

In vain today I tried every iteration of every video port which took a long time. I know the device ID is 3E9B8086 ,,,it would be helpful if you could share your OC Device Properties configs showing the bus IDs / Ports - that would save me a load more time once I downgrade the bios and start again.

Thanks again for the bios information.

This section you are asking for is quite short:

Does that help ?

Upgraded to openCore 0.6.3: I had to redo the EFI folder from scratch, trying to update the 0.6.0 EFI folder did not work...
Upgraded to Big Sur: smooth

willing to share your EFI folder with OpenCore ?
