I likely wrote that I "understand" that I should be able to select NVMe in the UEFI because such an option makes sense, because that's what one does now with SATA or IDE or RAID. I can't say I saw that anywhere. Also, I didn't see such an option mentioned in the online user manual I reviewed, making me question whether NVMe is even supported in my new Z170 motherboard's UEFI. It's easy to get confused wen using this M.2 technology. I'll be using one other hard drive, a regular SATA spinning platter drive. What additional consideration do I need to take into account when using a regular SATA drive? I'll keep in mind your suggestion that I may need to set my NVMe drive to RAID mode in the UEFI to get it to work properly and to be recognized as a MVMe drive. I wouldn't have thought of that. That RAID setting likely explains why the online user manual didn't mention anything about choosing NVMe mode. It would be helpful for the manual to contain more guidance in this regard. I've spent a lot of time looking around the Internet trying to get educated about M.2 technology. The time spent is paying off, though. I should be able to get my new rig up and running with the knowledge gained. Yeah, it's easy to get confused with this stuff. Thanks for the information. I'll need it. Dan

Your NVMe version of the SM951 should be bootable with your new board. I assume that board is the ASRock Fatal1ty Z170 Gaming-ITX/ac, since there is no ASRock board with the name you listed in your post. I say should only because I have never used an NVMe SM951 with an ASRock Z170 board. ASRock 100 series chipset boards support NVMe SSDs out of the box, or would have UEFI updates if necessary to insure NVMe support. ASRock has been and continues to be the leader in providing mother boards that support the latest flash storage technologies. That is one reason I've been using them for several years now. ASRock boards have supported UEFI booting since the Intel 7 series chipset boards (Z77, etc) were released, and possibly before that. I'm glad that you plan on installing Windows 10 in UEFI mode, that will automatically cause the appropriate EFI storage Option ROMs to be used. But keep in mind that NVMe is a very new standard, and using an NVMe SSD as a boot drive will need more configuration than a SATA SSD. In other words, the NVMe SSDs are not simple plug and play devices, yet. Using a UEFI (EFI) booting installation will save you some of the configuration work. I use a different ASRock Z170 board with AHCI SM951s. Currently, NVMe is not an available setting of the SATA Mode option in the UEFI. Intel has seemingly put NVMe support (and AHCI PCIe SSD RAID 0 support) into the SATA RAID EFI Option ROM that is part of the board's UEFI file. You may need to set the SATA mode to RAID if the use of a UEFI booting Windows installation does not automatically use the correct EFI Option ROM for NVMe SSDs. You wrote you "understand" that you should be able to select NVMe as an option in the UEFI. I'm curious where you read or saw anything about that. While selecting NVMe as the storage mode makes some sense IMO (will you ONLY be using NVMe drives?), there's more to consider. |

Hey, I think I've found the answer to my question right here in the forum, in the following thread: http://forum.asrock.com/forum_posts.asp?TID=305&PN=7&title=sm951-as-os-boot-device-information Dan (aka Fritz) |

Hi, Yesterday, I purchased from Newegg an ASRock Z170 Gamer mini-ITX motherboard, supporting the new Skylake processors. I haven't received it yet, but I have a question about its support for booting from a Samsung SM951 (NVMe version) M.2 SSD. I also purchased such an SSD. I see in the online user manual for this motherboard that this it apparently supports booting from a Samsung SM951 (AHCI/SATA version) M.2 SSD. The manual makes no mention about booting from the NVMe version M.2 SSD. I would like to be able to select the NVMe M.2 SSD in BIOS as the boot device, but I found no mention in the online manual about such an option. It only describes selecting SATA or IDE or RAID. I'll be installing Windows 10 Home, 64 bit, in UEFI mode. I also understand that in BIOS one should be able to select NVMe mode, as opposed to AHCI/SATA mode, if the BIOS/UEFI has such support for the NVMe M.2 SSD. So, my question is, can the motherboard I bought support, or can it be made to support, making the NVMe M.2 SSD a boot device and running in NVMe mode? Clear as mud? Fritz
