I have been having a problem with two of my systems.

Both systems are running unraid, and similar specs. But since this seems to be a boot issue, I think we can rule unraid out of this.

Both systems don't need a GPU, so I want them to run headless, which is working fine without other aic.

But if I add a PCI-e device, the systems won't boot.
I have tried an Adaptec HBA, and two network cards (intel and Mellanox)
but every time the debug LED lights up b2 (which is missing from the manual of the motherboard), and searching the internet I find it means that the system is having trouble initializing the GPU.

This makes no sense since I know it can boot without any GPU installed (also no other PCI-e devices) but as soon as I add other PCI-e devices it won't boot.

Both systems will boot with both the aic and a GPU.

System 1:
Asrock X99M Extreme4 P3.10
Intel Xeon E5-2630v3
4x4GB crucial 2133MT/s

System 2:
Asrock X99 Extreme4 P3.10
Intel Xeon E5-2680v4
4x16GB Corsair 3200MT/s
