Unless this is done programming UEFI BIOS is unpredictable. Rebooting the UEFI BIOS “mini OS” is required after making select changes in the UEFI BIOS settings before making additional UEFI BIOS setting changes. Using a SATA III drive in the M.2 socket DOES DISABLE SATA III port 1 and port 2.

Using a NVMe device in the M.2 socket DOES NOT disable SATA III port 1 or port 2. The manual is confusing in this one point, here is my understanding. BIOS -> BOOT -> Secure Boot -> OS Type -> Windows UEFI Build RAID 1 and keep M.2 as a non RAID memberĨ. F10 saved, reboot and go into BIOS againħ. Advanced -> PCH Storage Configuration -> M.2 PCIE Storage RAID Support -> Disable (Enable if not work)ĥ. Advanced -> PCH Storage Configuration -> SATA Mode Selection -> RAIDĤ. BIOS->Boot->Secure Boot->OS Type->Other OSģ. BIOS->Boot->CSM (Compatibility Support Module)->DisableĢ. However, this sequence suggested by a senior ASUS engineer did !!!įirst all drives should use the GUID globally unique identifier (GUID) Partition Table (GPT) partitioning scheme that is part of the Unified Extensible Firmware Interface (UEFI).ġ. The suggested sequence at “”How to build Intel RAID and keep M.2 available !” "” did NOT work for me and the system would not see the M.2 drive.
