Hello,
I am having an issue with the board posting when a PCIx1 NIC card is in the PCIx16 slot. Nothing powers on except the onboard NIC and the PCIx nic. Usually the keyboard and the USB drive light up and you can see activity on the USB drive.

Things to NOTE:
I currently have running an esxi server which is running perfectly fine with out the PCIx1 NIC. The entire setup is running headless(without GPU). I only use a GPU when I need to configure the uefi or need console access.

Any suggesstions? I was thinking that the pcix16 slot is locked to GFX cards only? If that is the case is there any way to get a modified bios?

TIA

B450 Gaming-ITX/AC board
AMD Ryzen 1700
Viper 16 GB DDR4 2400
