I am researching compatability with booting a NVMe PCI-express drive on a X10DRC-LN4+ motherboard. I am under the impression that a SKU with an "N" in it means NVMe support, but there is no mention of NVMe in the X10DRC-LN4+ manual. However, Intel states that any motherboard with at least UEFI 2.3.1 will support PCIe booting. In BIOS, if I change the OPROM setting for the PCI-e port from "legacy" to "EFI" will that mean that the bios will load the NVMe drivers off the PCI-e card and thus support booting an NVMe PCI-e drive (Intel 750)?
LN4 means Quad LAN with Intel® i350 Gigabit Ethernet Controllers. -N on motherboard means it has NVMe ports built in on board (for 2.5" NVMe PCIe SSD server system). X10DRC-LN4+ should work with NVMe PCIe SSD Add On Card such as SSD DC 3700 or 3600 (that SMC had tested)-- Set PCIe to EFI, set PCIe slot (that your AOC SSD plug in) to EFI, set boot device (that contains your OS installation media) to UEFI to install OS.
