This motherboard does not support bios flashback, originally used AFUDOS to force a bios flash. Which in turn just bricked my motherboard. Now I'm back with modified bios which I flashed with CH341A, DXE Driver is included and recognized.
Motherboard has 2 options for ReBar (Off/Auto), no matter the setting ReBar is still not working. Rebar is set to 4GB with your tool.
You have to use NvStrapsRebar on Turing, not ReBarUEFI
My mistake, I'll be right back to confirm. I just dowloaded wrong tool, but BIOS is flashed wiht NvStrapsReBar. Just checked the bios file used with CH341A.
I'll do a CMOS reset and report back. As currently it says it has not loaded driver.
Just reset BIOS, enabled Rebar which disables CSM and enabled 4G decoding, and loaded in to windows. I'm getting an error that the driver has not been loaded, even though it was flashed with modified BIOS.
I'm attaching bios file I used to flash my motherboard. Does location matter where it is added?
It is there, just by searching nvs you can find it in uefitool.

This board got ReBar support with BIOS 4007 which also added new CPUs with it 5800X which I am using. Could maybe roll back to that to see if it works, but I'm giving away all security updates with it. And would like to avoid flashing any more with CH341A as I did it absolutely RAW, without 1.8v adapter, so attempting more flashes might result in a fried IC.
