Hi Dieter (aka Fernando),
thanks for your very fast reply.
Yes, I read your very good guide.
I disabled the fast boot. I cannot disable the secure boot - in the secure boot options it is only possible to switch between UEFI-OS or Non-UEFI-OS (I tested both).
I cannot found any drive named PATA SS. Btw - I disconnected all other devices, so I see no drive at all.
The desired OS is Win 10 Pro 64.
I created the Setup at a USB stick with the media creation tool of MS.
Within the Win 10 setup I can access the drive, deleting and creating partitions, but I cannot install, because the setup say "no bootable Drive"
First I use the modded BIOS "mak387" in the Topic "P9X79 PRO BIOS MODDED FOR NVMe SSD "
Second I followed your guide and use the latest BIOS of ASUS and the UEFITool_0.22.1 and the NvmExpressDxe_3.ffs for modding.
After inserting the ffs file I got a lot of chinese characters in the Name of the DXE Name.
Only after the third try, I got a "good" Name.
I used the ASUS AI Suite to Flash the BIOS
I attach the BIOS
Thanks
Martin

Where did you see the name of the module? I just have checked the related ASUS BIOS and didn't find a DXE Driver with such name.

Hi Dieter,

your are great!!
Thanks a lot.
The first tip to use RUFUS for a UEFI-Boot-USB-Stick solved the problem, that Windows Setup didn't accepted the PCIe as a installable device.
The second tip to use the ASUS Flashback function brought the full solution.
After flashing again with this procedure I found the UEFI Boot Device in the BIOS and I was able to complete the Win 10 Setup and can now boot with the NVMe/M.2 PCIe
A little problem was that the flashback function didn't accept every USB stick, so I tried different ones until it started.

Again THANKS the genius Fernando
Martin

Hello everyone, I've been following this thread for a while now. I have an Asus Z9PA-D8C mobo, with 2X Intel E5 2680 V2 CPUs running Windows 10 Pro 1709 (latest update), and a Samsung 950 Pro SSD mounted on an adapter in a PCIe x4 slot, it works fine, but of course, I can't boot on it. I've tried the DUET metho and it works good.
I'd like to know if anyone has succedded in creating a modded BIOS for this server mobo from ASUS?

REMARK: my Samsung 950 Pro SSD is an OEM version, so, no, no NvME bootcode in the firmware... :-(

@Fernando:
Thanks for the reply Fernando, but if I'm not mistaken, as I stated in my previous post, the OEM version of the SAMSUNG 950 Pro does NOT have an option ROM... so I can't boot off it...

@Fernando
working great, thanks for putting this together.

@Fernando

Please help...

I've finally got a PCIE adaptor (the Asus one) and Samsung 960 EVO 250GB NVMe for my Asus P8-Z68V (original version).

No matter how many times I try I cannot get the board to boot in UEFI mode to install Windows via UEFI USB; DEL key and all function keys including F8 do not respond and the BIOS/UEFI splash screen stays visible for some moments before going to a blank screen with flashing cursor.
I have an nVidia GTX960 in PCIEx16_1 and the Asus adaptor/NVME SSD in PCIE16_2 (running at x8 and x4 respectively).
I have tried both updated GOP and original GOP in the graphics card with no effect.
The NVMe device is detected in UEFI as PATA SS as it should be; cloning the SATA SSD also brings up the Windows Boot Manager option for the NVMe device but I cannot boot from it.

I also tried re-modding the BIOS from scratch (original version 3603 from 2012) with only RAID ROM v12, CPU Microcodes, JMicron ROM and insertion of the NvmExpressDxe_3.ffs file with no improvement.
Removing all drives (SATA SSD and SATA HDD) other than the NVMe also had no effect.
The system also has the latest ME (8.1.70.1590) installed.
Can you advise what I may have done wrong or am I going to have to return my purchase?

Feeling very deflated at the moment...
Thanks!

Anyone have a link to a modded p8p67 evo bios I can just flash. This guide looks way to heavy for me to get my head round.

Ok thanks Fernando :)
