So, my next task is to install Win 10 on a NVME/PCIe add-in-SSD an MSI H81 motherboard as, of course, the boot drive. Do I read correctly that it is possible to use a Samsung M.2 NVME on a PCI adapter and install Win 10 without modding the BIOS?

Jeff

@Fernando, the reason I asked was that I read in one of the guides on this site that Samsung NVMEs (all? some?) have a module on board that gives native boot support for their drives with Win 10.

Fernando requested me to move this post from "Recommended AHCI/RAID and NVMe Drivers" so I am writing down under "[Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS"[/u]


I have inserted NvmExpressDXE_4.ffs file to my Asus Rampage IV Black Edition. It worked very well in the beginning, but after some time, it forget to boot from Samsung 970 Pro 512GB NVMe SSD. (Attached to Asus Hyper x4 Mini card)

I later go in bios and choose Boot Override, by choosing the visible Samsung 970 Pro 512GB option every time by pressing enter inside bios. It booted, but this is not good, problematic!

Removed all other boot devices, including USB's, DVD Rom etc. It still can not automatically boot. (Was not like that at the beginning!)

Unfortunately, there is a forgetting issue using NvmExpressDXE_4.ffs file! (at least on some mainboards)


Another forgetting issue appeared on Asus Sabertooth 990FX/Gen3 R2.0 mainboard. NvmExpressDXE_4.ffs file worked on it for a while (about a week), but later no. I have extracted 3 files from Asus Sabertooth 990FX R2.0 this time, worked flawlessly. (Bios file name: SABERTOOTH-990FX-R20-ASUS-2901.zip) There are no issues after 3 months!


Tried on Asus Z9PE-DS WS mainboard later. In the beginning it worked great again but, later same thing happened on it too.

This time, I have tried to install and managed to integrate 3 files (Nvme.ffs NvmeSmm.ffs NVMEINT13.ffs) from double x79 CPU mainboard called, Huanan AA1 x79-Dual. (Bios file name: rev2.49_orig_06-26-2017 22-51-33.rom.7z) Asus Z9PE-DS WS worked very well with those 3 NVMe files! (Still working fine after 2 months.) Bios structures of those two mainboards were looking very similar!


I have tried to install those 3 files to Asus Rampage IV Black edition from: Huanan AA1 x79-Dual, Asus x79 Deluxe and Asus Rampage V Extreme. But they did not worked at all. I am still trying, and searching 3 separate NVMe files from other mainboard bioses for Asus Rampage IV Black edition....


All people here whoever installed this, NvmExpressDXE_4.ffs file be aware, and keep an eye on, related with this forgetting issue! There are 3 mainboards do not like this file!


Note: There are also single NVMe files other than NvmExpressDXE_4.ffs. Those are: NvmExpressDxE.ffs, NvmExpressDxe_3.ffs, NvmExpressDxe_Small.ffs I will try those as well when I find a spare time.
(My plan for each of them running at least for a month for consistency, if I can not find appropriate 3 NVMe files from other bioses. So don't wait so soon!)

Update 21-06-2019
Last night, I have tried Asus x99 serie about 10 (all those 3 files in them are the same) one Asus z97 serie called Pro Gamer, one Gigabyte x99 UD7, one MSI x99 Godlike Gaming and one Asrock x99 Fatal1ty X99M Killer mainboard NVMe files. All of them did not work for Asus Rampage IV Black Edition! In the end copied NvmExpressDxE.ffs file for time being. I will test this forgetting issue with that file for a while.

Update 08-08-2019
At last I have found 3 compatible Nvme files for Asus Rampage IV Extreme and Rampage IV Black. The compatible Nvme.ffs, NvmeSmm.ffs and NVMEINT13.ffs files extracted from Asus TUF SABERTOOTH 990FX R3.0 mainboard, bios Version 0212. Very interesting, because this mainboard is an AMD board! I have also inserted the well known NvmExpressDxe_4.ffs file for comparison. The difference is at bios screen. With single NvmExpressDxe_4.ffs file there are 2 boot options, one of them is "Windows Boot Manager", and the second is "PATA SS:" But, with three separate files extracted from Asus TUF SABERTOOTH 990FX R3.0, only shows single boot option "Windows Boot Manager". Actually there is no performance difference. But, for one SSD, a single boot option looks more normal to me. Decision is yours....

@karakarga - on the boot page, do you have your NVME or whatever it's named in BIOS at the top of the boot list?

All those you mentioned at the end are old/earlier versions of the 4.ffs one (or the small one is same as 4, edited for space limited BIOS)

@Lost_N_BIOS

Yes I know those are older than NvmExpressDXE_4.ffs file but because of this forgetting issue, I may try them as well.

@Lost_N_BIOS - with 3 files, on the boot page, for Asus Rampage IV Black, I do not have my NVMe nor named in BIOS at the top of the boot list. With those single files, it writes "PATA SS:" only. Not gives specific drive name, like Samsung 970 Pro 512GB etc.

I have formatted my NVMe SSD by the way. It is blank right now. After operating system installation, I think it finds the name later. (If I am not fooling from original 3 NVMe files from other mainboards, that I tested earlier.) I will make an installation soon to be sure.

"... because of this forgetting issue, I may try them as well." you said. - I have one nVidia GTX 670 4GB, one Asus Hyper mini, one LSI 9311-8i and one Asus USB 3.1 card on my slots. I am not sure about their effect. If you have other PCI express cards in hand, plug them on as well, being for sure. But after this forgetting problem, I have removed other cards, except the graphics card, boot problem did not solve.

Anyone know how to flash back an Asus asus m5a99x pro r2.0, I can not get my custom bios to work for some security reason

@10AmpFuse - test flashing stock BIOS with flashback and your USB, if it works, then your mod BIOS is broken. Upload for me and I will fix for you.

I have flashed back using the newest official bios and downgrading it that does work how ever my modded driver isn't for some strange reason. Its 8mb so I had to zip the folder that I have attached thank you.

Stumbling into this forum and into this very topic, I guess im new to even looking at/modifying a bios. I have done recovery using other means, so I have flashed em. Never modified them what so ever. Now im curious about adding nvme support to older boards etc. Would it be possible to add it to a Dell laptop E7450 I E it has a WWAN port which detects 2x PCIE Nvme SSD's drives. But Bios cannot see or control said device. Are dell bios' even available to modify?

Thank you for the heads up, ill check thru these posts which have come before me. Just as a side note. there are very few 2242 NVME drives that will work in that wwan port. Picked up a couple of toshiba OCZ RC100 240GB pcie 2x drives. I found this info off dells community posts. I have managed to use a small msata drive hosting windows efi files and clover boot loader as an intermediary between sata bus to point to the nvme drive to be installed to. So I am able to use it as an installation area just not solo boot. Ultimately if there is a way to modify a bios to add nvme support, that would be the end goal. One heck of a project =D


Thank you again!
