The system either does not detect the UAD card

Card Working In Windows


Has anyone successfully used a UAD-2 PCIe card on an AMD Ryzen system, especially X570 chipset?
If yes, what BIOS settings or configuration changes were required?

I have attached my current EFI folder for reference.
This is the exact EFI I am currently using with my system.

If possible, please review the EFI configuration and check if there are any settings that could prevent the UAD-2 Solo PCIe card from being detected or working properly.

I am especially unsure about:

• PCIe-related settings
• ACPI configuration
• Any required quirks or patches for PCIe devices on AMD systems

If any changes are required in the EFI (ACPI, DeviceProperties, or Kernel settings), please let me know what needs to be modified.

Any guidance from users who have successfully used UAD PCIe cards on AMD systems would be greatly appreciated.
