is it instert into?
or insert after?

@olivia csmcore is used for identification of the correct volume, NVME driver is inserted after last element in the volume:

@lfb6 thanks for the quick help. I inserted it.
@Fernando I serched in both "pad" and got 11 results in both. That means i did it correctly right?

Here i am attaching
1) official asus bios downloaded from website -> G751JTAS.213
2) dumped bios by AFUWIN-> bk.rom
3) moded bios by uefi -> modedByUefi

@Fernando @Lost_N_BIOS
Can you add the missing original capsule for me? Please

I'm still waiting for my Kingston 1TB A2000 M.2 2280 Nvme. I will give an update after I flash new bios. probabbly this sunday. Thnak you so much guys

Hello @Fernando Thank you for your tutorial.

I have both problems mentioned in your tutorial for my Gigabyte GA-B75M-D3H rev 1.1
- MMTool always returns "file size exceeds the volume size" in both methods - compressed and as is.
- UEFItool adds and removes pads which as said, might break the BIOS. (I checked almost each and every row)

Can you please help me generate a moded bios for this MB

Hello Fernando, I have already made the modification and flashing the BIOS. I removed the RAID 0 of the 4 SSDs that I had and put an Evo 970 Plus with a PCIe adapter. Everything is perfect, except this that I show you in the capture. As you can see, the AHCI device cannot start, could it be because there is no SATA device? Is there something wrong with the modified BIOS?
What do you think?



Thank you so much for everything.

Hi all,
I've got a ASUS M5A99FX PRO R2.0 mainborad. I have modded my BIOS and installed it with no problems with Asus AI Suite. I have an KingSpec NVME PCIe recognized by OpenSuse 15.2 and Windows OS. OpenSuse 15.2 is installed on a SATA legacy disk in UEFI mode. Windows is installed on a SATA SSD Kingston in UEFI mode. I want to install Linux Mint or OpenSuse in my new NVME. I can install it, but BIOS doesn't shows the NVME device in order to boot from it after install. OpenSuse shows my Mint OS installed on my NVME, but when I select NVME to boot on the GRUB2 menú, it fails, can't find kernel. I don't know how can I use it in my Asus M5A99FX PRO R2.0 mainboard. I have checked modded BIOS and it's ok. I have disabled the CSM compatibility. It seems no changes.
Can you be so kind to help me?
Thanks a lot.

Hi,

Thanks a lot for quick reply. I can't see any device called PATA or similar whithin that section. Plase, find attached both original and modedd BIOS.

So sorry. My bad.
As far as I can see, everytime I disable CSM module, BIOS activates it again. I have a Nvidia GF-6800 VGA. But... What can I do to prevent this behavior?

You are right - it is impossible to get even the small sized NVMe module named NvmExpressDxe_Small.ffs properly inserted into the original BIOS without creating a natively not present Pad-file, no matter which BIOS modding tool (MMTool v4.50 or UEFITool v0.28.0) is used.
The reason for this problem is, that Gigabyte has put too many DXE Drivers into the related Volume. There is no space for any additional one, because the compression of the DXE Driver Volume is already at its maximum.
My advice: Remove any DXE Driver, which your specific system doesn't need/use, from the related Volume. Unless you want to use the "Wake-On-LAN" feature, the module name Ip6Dxe would be a good candidate, because it is the biggest sized one among the EFI LAN modules. I just have tested it: After its removal I was able to get even the "normal" module named NvmExpressDxe_4.ffs inserted "as it is" (uncompressed) into the BIOS without running into a Pad-file problem.
If you don't want to get any natively present DXE Driver removed, you should ask @Lost_N_BIOS for help. He knows more than me about such sorts of BIOS modding.

Hi, thanks again for quick reply. I have flashed the BIOS with Asus AI suite application with no errors. BIOS update from BIOS main menu fails for security reasons, but Asus AI suite seems it flashes ok... (I guess).
Do you know any method for double check if flash was ok?

EDIT, Asus app screenshot

PD. How can I grant to BIOS to load EFI files?
