So we now have: 100: 01 00 01 14 0x14010001 = ID 0x0001 (AER), version 0x1, next 0x140 140: 0d 00 01 22 0x2201000d = ID 0x000d (ACS), version 0x1, next 0x220 220: 19 00 01 00 0x00010019 = ID 0x0019 (Secondary PCIe), version 0x1, next 0x0 So they've just added ACS into the chain, perfect. Thanks, Alex
