Hi,
very thanks for this guide.
It possibile insert this nvme module into old Aption III Bios, with MMTool 3.26?
I search CMSCORE, but ther’isnt.
I have external programmer , not problem to try.
Thanks advance for all help.
There is no AMI Aptio III… its AMIBIOS8 generation, and no, the guide referes to a DXE driver for AMI Aptio V UEFI bios generation.
Theres this option for it, you may try it: [Experimental] NVMe Option ROM - BIOS/UEFI Modding / BIOS modules (PCI ROM, EFI and others) - Win-Raid Forum (level1techs.com)
Hi,
very Thanks for all info!
The issue for the ‘ASUS M5A97 R2.0 AM3+’
Followed **Only for ASUS BIOSes with the suffix .CAP:
To avoid problems while trying to flash later on the modded *.CAP file via the ASUS USB Flashback method, it is recommended to extract the “Body” of the original *.CAP BIOS. This can easily be done with the UEFITool by opening the *.CAP file, doing a right-click onto the “AMI Aptio Capsule”, choosing the “Extract body…” option and saving it as *.ROM file.’
Extracted rom done, insert Nvme, save as the new *.rom file done.
However how to replace .rom back the .cap file?
Asus EZ flash, only accept the cap file, however how to replace back the Nvme inserted rom file back to the cap file? thank you
@wuhu2
You dont need such mess… anyway for AMD bios, this mb CAPSULE size is 800h (2048), the extracted UEFI image can be later pasted/merged with an HEX editor.
The M5A97 R20 has USB BFB feature, so you can mod the .CAP file for NVMe according the guide and flash it, this is the correct method for flash the mod, not EZ.
The procedure will preserve the mb original data.
EZ feature method only for mbs without USB BFB and no security issues with mod files, usually older mbs.
Theres also in the forum ready to flash mod files for this model shared by users.
Thank you for your reply.
I have read the ‘[Guide] How to flash a modded AMI UEFI BIOS’
Usage of the ASUS “USB Flashback” feature
However, my question is how to prepare the moded .cap file?
I have the original A.cap file.
extract body to A.rom file
MMtool, open rom file, insert Nvme to A.rom file, save as, get the ready flast B.rom file.
What is the next step please?
How to convert B.rom back to B.cap?
Or just flash B.rom file by ASUS “USB Flashback” feature?
many thanks
No, you dont need to extract any ROM, edit/mod the .CAP directly, thats why USB BFB is the best option on flashing mods on board with this feature, there’s no concern of security issues.
Use the MMtool method for NVMe mod, put the mod file (M5A97R20.CAP) in an USB on root, thats it.

I modified and flashed my Asus UEFI ROM using the specific procedure described below, and all seemed to go well with an MSI NVME SSD in a PCIe adapter. But for some reason my PC kept shutting itself down, whether I was running Windows, Ubuntu, and even in the UEFI Shell. I finally flashed my original 0910 ROM back to my motherboard using BIOS Flashback, removed the NVME SSD from the PCIe slot, and reconnected the original SATA SSD instead. Now I’m waiting to see if the system will continue to shut down.
This is what I did - I opened P8Z77-V-LE-PLUS-ASUS-0910.CAP in UEFITool 0.28.0. I found the Volume containing the File with the Text description “CSMCore”. I scrolled down and highlighted the last file in that same Volume, right-clicked and then clicked “Insert After” and inserted there the file “NvmExpressDxe_5.ffs”. Then I clicked File > Save Image As, and saved it as CAP file with a different name. I flashed this modified CAP file to my Asus P8Z77-V-LE-PLUS using AI Suite II.
I installed my NVME SSD in a 4x PCIe slot. My PC booted fine. I had earlier used Clonezilla to clone my SATA SSD to the NVMe SSD, and since it booted to Windows just fine, I didn’t reinstall Windows on the NVMe SSD. I doubt that not reinstalling Windows caused the shutdowns, because the shutdowns also happened in a fresh installation of Ubuntu and also in the UEFI Shell.
I want to emphasize that these were “orderly” and not spontaneous shutdowns - both in Windows and Ubuntu, a message would pop up saying that Windows or Ubuntu was going to shut down, and then the PC did so. I thought maybe it was just hardware failure and not the BIOS, but I had another shutdown when I replaced the NVME SSD with my original SATA SSD. That’s when I decided to flash back the original unmodified BIOS.
So I’m wondering what was triggering the shutdowns. Was it something happening in the firmware? Could it be overheating or something, but if so, would it have been an “orderly” shutdown?
Also I’m wondering if it would have made any difference if I had extracted the body of the CAP file to a ROM file and worked with the ROM file instead of the CAP.
If anybody has any thoughts or suggestion on this I would be very glad to hear them! I did a search of the forum looking for any similar “orderly shutdown” problems with a modified bios, and didn’t find anything.
@jimspoon Welcome to the Win-Raid Forum!
Flashing of a modded, but still capsuled BIOS file without using the ASUS own USB Flashback feature may have been the reason for your shutdown issues.
That is why I recommend
a) to reflash the original BIOS,
b) to remove the BIOS capsule,
c) to modify the .ROM file and
d) to flash it according to >this< Guide.
If you want security, that the insertion of the Nvme module has been done correctly by the UEFITool, please attach or give us a link to your modded BIOS and the original BIOS.
Good luck!

thanks for you very kind guide! i am trying to do the mod for my supermicro x10slh-f but bother methods sadly generates that extra pad file and i did not go ahead to flash as im worried for bricking my board.
wonder if you can help me to take a look or advice what can i do?
TIA!
@clarencelimzj
When this situation happens in certain bioses, the best chance is try using the different versions of the UEFItool 0.25/0.28 and/or MMtool 4.x/5.x, eventually a correct mod will be achived.
unfortunately, i tried all versions and variations and none seem to work! wonder if anyone have some other insights?
thanks
@clarencelimzj
Please attach the original BIOS or give me the link to it. Then I will test different tools.
Sure! Latest firmware below
