Thank you Fernando
Hello!
I’ve been attempting to add NVMe support for a X10SLL-F board I’m using for a home server. I ran into the issue with padding described in this guide while trying to patch the DXE module in. The discrepancy I found looks like this, with the modded bios on the left. The pad entries under the highlighted entry seem to be missing.
I’m a new user, so it looks like I can’t upload attachments, otherwise I’d provide the bios files too.
Also, its worth noting that I tried just using the modded file form this post:
but the AFUDOS command seems to be hanging. I’ve left the system running for now, but I will probably go interrupt it and flash the unmodded bios for now so I can reboot.

Welcome to the Win-Raid Forum!
You are right - due to the big amount of pad-files it is not easy to get any NVMe module properly inserted into the BIOS file named X10SLL1.308.
Nevertheless I finally succeeded by using
a) the AMI Aptio MMTool 5.0.0.7 for the BIOS modding and
b) the uncompressed “NvmExpressDxe_Small.ffs” module for the insertion.
As far as I could see all natively present Pad-files stayed untouched after the insertion of the NVMe module.
Tip: You will find the working MMTool v5.0.0.7 by doing a Google search for “MMTool Aptio 5.00.0007”.
Good luck!

Thanks Fernando!
It actually looks like the BIOS from the other post I referenced did end up flashing correctly even though the flashing tool hung at the end of the process. But this is kind of an unsatisfying answer I think, so I’ll take a look at the MMTool you mentioned and see if I can get that to work.
Hi,
Sorry I am having issues with my Supermicro board (X10DRU-i+). I got to the part of the instructions to show the volumes of DXE. But my BIOS doesn’t have a CSMCORE listed. And the note placed in the instructions doesn’t make sense to me.
Note: In the very rare case, that no module named CSMCORE is listed, you have to search for the upmost Volume, which contains modules with the letters “DXE” within their name.
I’ve also tried to insert the EFI NVMe module. And all my “Insert after…” options are greyed out and I can’t actually put it into the BIOS. I’m quite stuck, and any help would be greatly appreciated.
EDIT: Well I didn’t get it figured out. But I did find this post SuperMicro X10DRU-I+ BIOS 427 mod for NVMe boot. Where someone already modded the BIOS for my mobo so I just used this and it worked great. So for anyone looking for it go to that post.

Welcome to the Win-Raid Forum! It is fine, that you finally succeeded and now can boot off your NVMe SSD.
The sense of this additional note was to help users, whose mainboard BIOS doesn’t contain a module named CSMCORE, to find within the voluminous BIOS the target “DXE Driver Volume”, where the NVMe EFI module has to be inserted. Note: There are a lot of BIOSes, which contain more than 1 DXE Driver Volume and it is very important to find the matching one, because otherwise the BIOS modification would have no effect.
Please explain why this part of my guide doesn’t make sense to you. I would be grateful for a better understandable wording.
Thank you very much for this guide. Unfortunately, I am unable to patch my Gigabyte GA-H87-HD3 bios without either getting pad files added or removed. I’ve tried with both MMTool version 4.50.0.23 and 5.0007. I have tried all 3 bios versions that are available (F10, F9, F8). Compressed NvmExpressDxe_Small is the only option that isn’t too big.
Any help would be greatly appreciated!
@c0d3m0nk3y Welcome to the Win-Raid Forum!
Contrary to you I was able to get the NVMe EFI module inserted without getting any pad-files added or removed.
Solution: Let the UEFITool do the work.
Here is the result I got:
Good luck!

Awesome, the UEFITool seems to have worked indeed. I shied away from it because of your warning that you really need to know what you are doing when you use it but it wasn’t so bad after all. It even managed to insert the full-size module.
The one problem that I still have is that I can’t tell whether it worked. The flash tool seems to be flashing the modded BIOS (it says erasing, copying, verifying or something along those lines) but it was suspiciously quick. Unfortunately, I’ve had already flashed the unmodded F10 version before and now I can’t tell whether I have the modded one or whether the flash tool just skipped it because it thinks, there is no change. It still says no boot device found, but obviously that can have all kind of causes. It also won’t let me flash back to an older version.
I’ll have to play around with it a bit more. Either way, thank you very much for your help! Much appreciated.
This is ALL explained in the guide, the guide IS for reading not to “hang on a wall” like a paint…
The method for flashing the mod on this mb generation is using Q-Flash ONLY.
EDIT: Windows 8 WHQL features disable (CSM) if not mistaken, cant remember if it present in these bioses from Gigabyte
Thank you for pointing out that there are instructions that I had missed. Unfortunately, Q-Flash is what I have already used. There is no CSM option in the BIOS.
PS: I did manage to flash back to F9 with Q-Flash (previously I had tried my original backed-up F2 version) and then back to the modded F10 version. So I know that I am running the modded BIOS now. Unfortunately, I still don’t see any PATA drive. I’ve set everything to legacy but there is no CSM option
Ah ok, yes. I’ve had it set to “OS (other)”. There is also “Windows 8” and “Windows 8 WHQL”.
I did manage to get it to boot into Windows now! There is one catch though. I had to move the M.2->PCIe adapter card to the first x16 slot. For some reason, it doesn’t work in the x4 slot (the only other slot that fits), which is a bit annoying because now I either have to use onboard graphics or move the GPU to the slow slot.
If anybody know why that is, let me know. Otherwise, thanks alot for your help!
PS: Setting the PCIe speed of the port to 4x instead of leaving it on auto fixed the issue. Now I can also boot from the other slot!!
Congratulations, glad you figured it out, enjoy it.

Hello friends,
Im trying to get my H61M-ITX to boot pcie nvme ssd but no luck.
To be honest I did not know when I started this build to get a MC server that I will need to mod the BIOS 
I followed the guide and got modded BIOS using MMTool, got to the PAD file part and I’m almost sure I’m good but I wanted some of you smarter people to double check me.
Can someone kindly check my BIOS if its ok for flashing?

Seems correctly inserted in the right bios volume, no changes regarding pad-files, so it appears ok.
This is not any kind of confirmation that all the operations will be risk free.
Good luck.
Thank you kind sir. 
I understand that its all on me if it fails.
Fortunately I found ebay seller that sells already modified BIOS for 16$ so if it fails not all hope is lost.

Welcome to the Win-Raid Forum and congrats for having succeeded with your work!
Since you obviously have done the BIOS modding yourself by following my Guide (start post of this thread), I have moved your check request and MeatWar’s reply here.
It doesn’t make much sense to start a new thread for each BIOS modding check request.
@MeatWar JFYI
I have followed the guide to install Windows 10 and after installation is complete there is no Windows Boot Manager option in the bios, I have reinstalled it 4 times with no luck, tried all pcie ports on my motherboard and the Rufus stick is made correctly and the NVMe drive is GPT.
Motherboard: GA-Z77X-D3H rev.1.1
BIOS: [OFFER] Gigabyte GA-Z77X-D3H NVMe mod
Only shown is PATA SS which I know cant boot.
Which Boot Options does the BIOS show and which NVMe SSD partitions does the Disk Manager show?
The Win10 installation in UEFI mode cannot be completed without the creation of the EFI Boot partition (whichever name it has).
