@Fernando in addition to my above comment, I compared the modified and original Bios and I had found the only difference. See below image.

What should I do to correct this discrepancy?

@ Fernando and all others
A quick update I was able to successfully flash the modded bios for the ASUS P8Z77VLK 1402 original bios to the nvme using your procedure on page 1 and then flashing the mod bios using this procedure:

Thanks @Fernando will follow your advise...:)

Tried ur dump, with both tools UEFItool 0.25/AMIBCP4.50, it creates a new pad-file in bios structure, after the module insertion.
But it seems that the UEFItool 0.28 does not create any Pad, so its ur best shot, at ur own risk.
Only space for small DXE module.

EDIT: Ill repeat again... the insertion of the small DXE module with the UEFITool 0.28 did NOT made any extra PAD FILE.

Ur saying u got it right with MMTool, share ur MOD for confirmation then, if u want.

EDIT 14/07: Glad that u manage ur own solution, still if u want my version of the small DXE with UEFItool 0.28, here it is.

Hi MeatWar, I already tried and used UEFItool 0.28 and it created a Pad File on my system as well.

But when I used MMTool v4 as per advised by Fernando, it did no create the Pad file. I'm just waiting for some confirmation before I use it as I do not want to brick my system.

Thanks for the advise.

Hi @MeatWar and @Fernando Thanks for taking time to answer my query.

Below is the Wetransfer link for my Modded Files and Softwares used.

I did two tests each for UEFITool 0.28 and MMTool Aptio 4.50.0023
- First test is using the Larger NVME ffs and removing udp6dxe
- Second test is inserting only the smaller NVME ffs

I verified all the modded file using UEFITool 0.28. Strange that ONLY the 'Mod by MMTool Aptio 4.50.0023 using Large NVME removing udp6dxe' have NO PAD FILE.
The remaining mods have PAD-FILE in it.

The below image shows two files Modded using MMTool Aptio 4.50.0023. But using different NVME ffs yields different results.

@thorne

Ive downloaded ur attached MOD files, only the first one in the folder "Mod by MMTool Aptio 4.50.0023 using Large NVME removing udp6dxe - NO PAD FILE", seems to be OK in correct inserted volume position and no PAD file.
If u want my mod file, its attached now in my previous edited post, as i said before made with UEFItool 0.28, no modules removed, only added the small DXE. Good luck.

EDIT: AS always, any provided files, its user OWN risk in its use and no responsibility on any damage/failures to the system.

@MeatWar I downloaded your file now. It's better to use your file since you have more experience in Bios modding unlike me who started just 4 days ago...:)

Will try flashing the PC tonight or tomorrow and provide update afterwards.

Thanks...
