   Hi, 
   
  I have a X570 mini ITX TB3 Phantom Gaming motherboard and installed Windows 10 1909 after having updated the BIOS to 2.0. I have installed all ASrock drivers ans still have 4 unknown PCI devices in Device Manager ? 3 Unknown PCI devices and 1 unknown PCI device Encryption/Decryption. The SBI_TOM header is not connected on my MB as I don't have a TPM. What can I do to get rid of these unknown devices, other than disable ? Thx & KR  |

   Get the newest chipset driver from AMD and install it. 
   
  This replaces the old driver from AllIn1(v19.10.16_19H1_WHQL).zip  |
