[HowTo] Get full NVMe Support for all Systems with an AMI UEFI BIOS

Hello, thanks for this great tutorial. I have successfully prepared modded bios for Maximus VI Hero Intel Z87 motherboard but not flashed yet because I have some questions:

  1. Why “The on-board SATA Controller should not been set to “RAID” mode within the BIOS.”? Currently I have 2xssd in raid0 working flawlessly and wanted to add nvme and keep also sata disks in raid mode.
  2. I can install W10 from usb with SecureBoot enabled. Do I realy need to disable it when bios mod done and nvme ssd added via pcie nvme adapter?

@zbigl Welcome to the Win-RAID Forum!
Although I am not a clairvoyant, here are my answers:

  1. According to some user reports it was not possible to get Win10/11 installed onto their NVMe SSD as long as the on-board Intel SATA Controller had been set to “RAID”. On the other hand it seems to be possible to re-enable the RAID setting and to re-use the existing RAID array once the OS installation onto the NVMe SSD has been successfully completed.
  2. You should not try to get Win10/11 installed onto the NVMe SSD while “Secure Boot” has been enabled within the BIOS. It is very unlikely, that you will succeed.

Good luck for the flashing of the modded BIOS!

Ok, thank you for quick answers

I’m trying to NVME-mod a BIOS file for a GA-B85-HD3 rev2.1. Modded BIOSes for earlier revisions of that mobo are available, but sadly not for rev2.1.

Comparing my original BIOS file to my modded attempt, I can see at least one pad file missing from what i presume is vol2 (the DXE volume) of the modded version? Screenshot shows missing file highlighted in blue. I used the NvmExpressDxe_Small.ffs file, inserted compressed, as the DXE_5 version didn’t fit.

Can anyone verify that the modded BIOS (B85HD32.F4.fd) is good, please? Or if not, mod the original (B85HD32.F4) for me? Both attached in single zip file.

Your modded BIOS may work or not (nobody can predict it), but is definitively “not good” due to the missing Pad-file.
By the way - the UEFITool 0.28.0 is able to insert the NvmExpressDxe_5.ffs module without touching the Pad-file.
Here is the proof:

Cheers for the info! I’ll give the UEFITool method a go.

EDIT: Ok, that worked. I modded, and then flashed the BIOS with the inbuilt Q-Flash, without issue. Thanks again for the help :slight_smile:

I’ll go and drop the file in the GA-B85-HD3 thread so others can try it if they want.
