Note 1: Intel VMD is supported by CPU2 SLOT9 and CPU2 SLOT10.
Note 2: After you’ve enabled VMD in the BIOS on a PCIe slot of your choice, this PCIe
slot will be dedicated for VMD use only, and it will no longer support any PCIe device.
To re-activate this slot for PCIe use, please disable VMD in the BIOS.
