Aurora R12, no Post/Bios, DisplayPort after latest VBIOS
Hey all
Is it just me or did the latest VBIOS/BIOS for the R12 and RTX3090 bork something. I now have ReBAR support but can no longer see the post screen or access BIOS when connected via DisplayPort. All good via HDMI.
I've seen some people reporting similar. On previous models R10 and prior the solution seemed to be to disable secure boot and avoid the UEFI environment but not sure that is possible on R12s.
Good to know if anyone else is having same issues.
Thanks
Nate

The latest bios seems to have introduced an issue with the Display Port. Several others have reported the same behavior on their RTX 3000.

Lets hope its picked up in the next BIOS release. I mean, its not like I poke around in the BIOS too often but its a real pain having to connect via HDMI any time I want to tweak something...

Another solution would be to backflash until a fix becomes available however you'd no longer have rebar support.

Do we know if it was the VBIOS or system BIOS? I think it was the VBIOS from late May?

It is video BIOS update for rebar. Here is the post that summarizes the issue:
