ASRock X870E Nova forcing boot from IGPU?

[DaaG]

Hello all, I am having an issue with DGPU installed hanging on code 97, all BIOS defaults have been reset, I changed primary graphics to IGPU, but as long as DGPU is installed it will hang on 97, monitor will show HDMI1 which is IGPU connection, and DGPU is DP1 but I cannot get through post unless I pull at least one power connector on DGPU. But then IGPU shows as gpu0 and I need DGPU to be set to 0.

IDK if it is any security settings, or if the GFX option with no help string should be off or on. But I have went though as much as I could to try to force boot from IGPU with the DGPU installed and connected completely.

CSM is a question because it says to turn off for DGPU, and the Promintory boot options 1st is set to uefi only.

Kind of at a loss of how to force it to boot with both gpus installed and connected. This is related to vbios flashing, but I think I have a BIOS setting incorrect to be able to recover.
Any help would be appreciated. It is a strange behavior, I am on MOBO BIOS 3.20

Thanks, DaaQ.

Try a different slot for the gpu... or try the gpu in a different pc.

Are you using a pcie riser card? Those crap out a lot...

Is this on your system in sig or....?

Nope let me fix that.

Corrected. Tried the AMDVBFLASH but got borked, I did not realize there are 3 bios switch positions. Have HW flasher arriving tomorrow, just not sure which chip is on the backplate side of the Nitro+ Has one on each side.
