@raven1234 - thanks! First, you have to remove the BIOS from the capsule container, then modify. Do not put back into a capsule (Nor rename .cap)
If I was you, I would start over and do the mod again, with the below first if you didn’t do that the first time.
Because I am not sure, if you extract the rom now, if checksum or something else needs corrected in BIOS after the mod, which UEFITool already did, but if contained in cap file that would be part of the checksum making it wrong to extract after the mod.
Hope you get what I mean. I think it’s safer to redo the mod, extracting the rom first from capsule, insert the NVME module, then save/rebuild and then flash.
Then flash as I mentioned. If the NVME mod is all you did, then it looks correct to me, except for the above concerns.
Open the .cap file in UEFITool, right click AMI Capsule file, and choose Extract body.
Then, that file is what you want to flash with using methods for flashing modified BIOS, and what you should do before modifying BIOS.
You can flash with AFU or FPT, How to with AFU Is in the guides linked above
Here’s how with FPT (Intel Flash Programming Tool) - FPT - >> FPTW.exe -F N751JKAS.205.M1 -savemac -BIOS
You need to use FPT from version 9.5 system tools - https://mega.nz/#!CdFUSaxb!DkpSh5cUQN7hs…IurQ18sGI_O3KR4
