Notes: 1. When installing an NVMe device on a motherboard, please be sure to con-
nect the first NVMe port (P1_NVME0) first for your system to work properly. 2. To avoid
causing interference with other components, please be sure to use an add-on card
that is fully compliant with the PCI-standard on a PCI slot
