@Fernando:
Hi, I have the same mobo as @Tunak and I just bought a Samsung 970 Pro and PCIex bracket. Would you please repost the file with the BIOS modded for you for ASUS Z87-PRO. The previous link you posted doesn't work, download never starts ... Thanks a lot !

@Fernando
I'v got Alpha version from https://github.com/LongSoft/UEFITool/releases and this is my main mistake.
There are no problem whith rel. v0.26.0.

Now I have bootable Samsung 970 Evo.
Amazing, but it work :))
THANKS a lot, Fernando!
I'm happy!

Attachment - MOD BIOS for Gigabyte GA-B75M-D3P with NvmExpressDxE_4.
Can your approve my work?

Hi @Fernando,

In fact I did modified my own after downloading it from Asus support website (pls see attached). However, I saw some BIOSes modded with 3 NVMe modules Nvme. NvmeSmm, NVMEINT13 (like I did mine) or with NvmeExpressDxe_4 (like you did yours). Since I haven't quite understood the difference I wanted yours as an indication of the path to follow. BTW link finally worked, I think it was my browser, won't download in Firefox but did download in Edge, go figure ! Thanks a lot !

Haven't uploaded the file with my previous message

Hi Fernando,
Thanks a lot for this amazing tutorial :)
I just modded my Z9ped8 ws bios with MMtool
Nvme module just inserted and everythings are fine unless I tried to flash my bios!
EzFlash just show an error which contains „Security verification failed“.
It seems modifying cap file caused invalid signature!
As I know there is no way to have valid signature with such a tool!
So my question is:
Is there any way to have some sort of bin file from cap which is make me able to write it with programmer into bios chip? (I already have a backup chip with original bios installed so it is secure enough to play with programmer on second chip)
So in this case I can bypass security check :)

Thanks a lot and have a lovely day

Thanks Fernando - you and the rest of the team who contributed to this are legends !

I followed your very thoroughly documented instructions precisely, and Bingo! ..... it worked first time :) ..... on first boot, it even automatically finished off my semi-installed Windows 10 installation on the NVMe SSD.

Windows now boots up in 8 seconds.

Kit:
Motherboard: ASRock Z77 OC Formula
EUFI BIOS: v2.40 beta
CPU: Intel Core i7-3770K
NVMe SSD: Adata SX8200 Pro 1TB installed in an Angelbird Wings PX1 add-in card.

I have a problem with my Rampage IV Extreme X79 and NVME. I managed to mod the bios 5001 through your guide (thanks!) - in order to recognize the Asus X16 Hyper m.2 card and I have two M.2 drives in it. (970 EVO)

Cards installed:
2x1080TI (slot 1 x16, slot 2 x8)
1xAsus Hyper M.2 x16 (slot 3 x16)
1xAsus Essence STX (slot 4 x1)
1xempty (slot 5 x8) - if used, slot 3 turns into x8 mode and the Hyper card is no longer found??

Question 1 -
Why does it only work with the Asus Hyper card to be found in the bios on Slot 1 and 3 (the x16 slots) ?
None of the x8 slots find the card or any drive. Can this be changed somehow ? It would really help me if it could and I will only use the 2 drives hence only an x8 is needed.

Question 2 -
Is it any bifurcation bios available for R4E in this forum ? If so for which slot ? (so I can use both drives and not only one)

System:
R4E X79, I7-3930k @ 4.7 GHz, 64 GB 1866Mhz Ram, 2x1080TI Nvidia FE, Asus Essence STX, Asus Hyper X16, Samsung Evo 970 1 TB (not found yet..), M.2, Samsung Evo 970 250 MB M.2, Crucial MX 525GB x 2, WD 1.5TB Green, Corsair 115i CPU Cooler, 8xNoctua 120mm Fans, Corsair 740 Cube Chassi, Logitech G910, G903, Powerplay Wireless, Bose QC, 75" UHD 4k Samsung TV, 11.2 Hifi System Canton References/Velodyne DD-15s, Onkyo PA-MC5500, Onkyo TX-NR3010

@Fernando
Just a quick upate letting you know everything went perfectly. I am now running a NVMe Windows 10 OS. I was on Sata 7200, going all the way to a NVMe, let's say this is a huge step up. Your step-by-step guide was easy to follow. I am including 2 benchmark screenshot to see if my results are within expected range for Intel 660p Series M.2 2280 1TB PCI-Express 3.0 x4 3D NAND Internal Solid State Drive (SSD) SSDPEKNW010T8X1.
I guess so, I suppose I would need to run this SSD directly on a motherboard with Native M.2 slot to get better results.

Also, just asking, but when starting my computer, I get to a Windows OS selector, can I skip this step? I have 1 NVMe SSD with Win10, and another one being a SATA 7200 with an old Win10 on it. If I erase that old OS, will I still get that Windows select screen on start up?
Thanks for your precious help!

Wish you the best!
