I have a seven year old Asrock B75 Pro3 motherboard.
There is no support for M.2 but AMI UEFI
it has bios.
Intel Pentium 2130 + built-in VGA
8gb ddr3 ram.
I made the nvme driver for bios
paste (NvmExpressDxe_Small.ffs).
I installed the bios file.
I inserted an Axagon PCEM2-S NVMe M.2 adapter into the PCI-E 3.0 x16 socket.
The adapter includes a Silicon Power 256GB A80 M.2 NVMe 1.3 SP256GBP34A80M28 SSD.

Finally, Windows 10 x64 Pro was installed.
Partition table GPT.
Bios boot option UEFI.
Windows installed without problems.
Because of the weak parts above, I didn't expect much
system for acceleration.
In fact, the acceleration is huge.

Within a few days a five year old Asrock B85M Pro3
motherboard will be similarly accelerated.

Thanks for the detailed post.

whether it is a good idea for a specific system with native NVMe support to replace the "body" of the NVMe.ffs module by the "body" of the NvmExpressDxe_4.ffs module.

Hello,did your ASUS P5Q deluxe worked well with the NVME SSD as an bootable device?

Hello. I have an evga z87 classified board and i want to boot from adata sx8200 pro 256gb ssd in some generic pci-e x4 nvme adapter. The problem is, ssd is not detected anywhere with or without modding bios. I inserted NvmExpressDxe_Small.ffs compressed to the bios (only way it would fit) using MMTool succesfully but that did not change anything, i can't even use it as data drive in win10, diskpart and device manager shows nothing. Same in windows 10 installer, not showing up and it's the only drive connected atm. I tried many different settings in bios, different pci-e slots etc but nothing has worked so far. I can try getting a new adapter but i'm not sure if it will help.

@Balto - if drive is not showing up in device manager even as a secondary/spare data drive for testing (in already installed OS), then the PCIE adapter or NVME drive itself may be faulty. No mods needed to BIOS for that kind of testing.
Here is super cheap adapter I use with that exact same NVME drive, so you can try another one to rule out your current, then if this still doesn't work I suspect NVME is DOA (it happens)

The last thing i tried was moving pci-e adapter to 1st slot instead of gpu (my mobo has 6 pci-e slots) and tiny light lit up on adapter, but system was failing to boot showing A2 code which manual says means ide detect so i am not sure if it would work this way. GPU was in 2nd and 3rd slot, clearing cmos did not help.

Look at your manual and see which slot is at least X4, and not share with GPU. Use that one. Green LED is good sign adapter is OK
YOu may need to use latest BIOS, if you are not already, even to test it as spare/data drive. To install windows, you need to make your USB Staller GPT partition and then instal to RAW or GPT partition (or let wndows do it)
Follow all steps at point #4 in the "This is what should I do section" at page one

If you need mod BIOS, and are not sure you did it correctly, link me to your latest BIOS from manufacturer page and I will modify for you.

Apparently all my pci-e slots were disabled by physical switches on mobo (only 1st was set to on) and now light on adapter lits up in every slot, but again, issue remains as disk is not listed anywhere. Regarding bios i am using latest one, i would be grateful if you could modify it for me so i can be sure it was done correctly.

Z87 Classified BIOS 1.09

@Balto - I've never heard of such a thing, maybe on rare server board or something. But yes, I remember these Classififed boards had lots of extra stuff one might not see on other boards, or may never use unless extreme overclocking. Good find, and glad you were able to notice this!
As mentioned, BIOS mod is not needed to see the NVME drive from another OS, as a spare secondary data drive. Did you look at it from another already installed system yet, or are you only trying to install Win10 to it right now?

Maybe you did mod in wrong area? I had no issues to use normal larger sized NvmExpressDxe_4.ffs Ohh, I see, only MMTool 4.50 and 5.07 tells you this, you can use MMTool 5.02 and the larger normal sized one
FIT Table must be corrected after the edit, probably any method would require this, even with small one inserted, due to microcodes in same volume as main BIOS volume where NVME goes, I tested a few other method and aill needed this fixed post-edit

Here is mod BIOS done via 5.02 + FIT fixed (large NvmExpressDxe_4.ffs)

I woke up today, checked device manager and the disk is finally visible and working! what's funny i did not change a thing since yesterday, i left it in pci-e slot where it was not working despite me trying everything i could do, lol.

@Fernando @Lost_N_BIOS
Yes, everything is working, i just finished installing fresh win 10 copy on ssd nvme drive, thank you.

I have MB Asrock Z87 Extreme4 https://www.asrock.com/mb/Intel/Z87%20Extreme4/#BIOS. I have updated the latest bios [Beta] 3.40B (Enhance M.2 compatibility when using a PCIe to M.2 adapter). I plugged the SSD XPG SPECTRIX S40G RGB PCIe Gen3x4 M. 2 2280 Solid State Drive + EYI Swift MX16 M.2 NVMe SSD NGFF to PCIE 3.0 X16 Adapter M Key https://www.amazon.com/JEYI-Adapter-Inte...s/dp/B07PZV9K9N into the PCIx16 slots. But neither BIOS nor Windows 10 x64 detected an SSD. I tried Mod bios as instructed but it still didn't work. I have searched the forum but found no similar cases. Please help me. Thank you very much...
