@Fernando:

Hello
I flash the bios from the windows application "Asus Update" of "Asus AISuite"
The "asus update" application when flash the modified bios, informs me that it was correct and asks me to restart. everything seems correct

But....
If I flash bios from "USB BIOS Flashback" inside bios from usb, I get the following error: "Security verification failed"
I have correctly named the file ".CAP"

Regards

@jpovedam:
I recommend to repeat the BIOS flashing of the modded BIOS by using the USB Flashback Feature of your mainboard.
Don't forget to rename the BIOS file according to the ASUS USB Flashback rules. It is nt enough to rename the extension of the file.
Furthermore I recommend to use another empty, FAT32 formatted USB 2.0 flash drive with a low data storage capacity.

Hi Fernando,
I have finally got it to work. You were right about making sure to create a perfect EFI boot partition on the NVMe.
I was unable to achieve this using the refus fresh install of windows method so I decided to clone my 860 EVO SSD using AOMIE backupper (free version) on to the blank NVMe (GPT partition) my :D drive.
Utility is located here: https://www.backup-utility.com/windows-1...nvme-4348i.html (this link includes instructions on how to clone standard SSD onto NVMe ssd and make it bootable)
This clone method seems to have created a perfect EFI boot partition. Thanks for lead Fernando. All working fine now.

(1) I cloned my SSD to my NVMe and rebooted the machine.
(2) Checked bios to look for "Windows Boot Manager" option but nothing was present there.
(3) Rebooted again and hit Enter and F12 to get a menu for "other boot devices" and "Windows Boot Manager" option was listed under all the SATA devices. So I selected that.
(4) In the bios all I had to do was enable UEFI option in order to force my NVMe drive to boot into windows, which worked nicely. I can see my all my other drive letters too.

My bios mod worked, thanks to this forum I'm up and running. Great work people :-)
I am now getting very good read write speeds on my Samsung NVMe (not the best) but that's another matter.
If anyone else needs help with my system spec, I'll be more than happy to help.

Thank you.

hello

will this bios mod work with Asus Rampage III gene (x58) and samsung 970 evo ?

thanks for the reply fernado.

Hi , I've modded bios using your nvmexpress add on ,still can't get the ssd working . I have Windows 7 and H81M-E33 motherboard,the ssd is m.2 integral 2280 240gb ,trying to get it work using adapter for pcie .The SSD is not seen in bios ,neither in Windows . I've tried to use the Clover ,couldn't copy files for booting.And DUET ,I think the usb stick with DUET was working but I didn't booted my pc into windows or windows installation.I have installed microsoft fix for SSD from their website the fix 477475.And runned EFI installation of windows 7 with hotfix ,couldn't find the ssd there too. Can You help me making this work ?

I have tried with these two files ,and different versions of bios newest is 6.80 ,I've used 6.70 and 6.60 too. bios files MSI H81M-E33

Tried to put nvmexpress dxe after Float value ,and in the bottom of bios.I was doing also extraction of nvme files from other MSI motherboard Z97 Gaming bios and inserted them into bios file,didn't work as well.

Also I had problems with bios update many times. The bios was freezing the pc when updating.And when I update it goes to 96% and then restart.

Fernando Tell me please , this module is suitable for moding the BIOS "NvmExpressDxe_4" module or need NvmExpressDxE_2 GUID ?

asus b8z77v pro thanks .

I've attached bios files after integration , one of this is with integrated NvmExpressDxe_4.ffs into latest bios from motherboard manufacturer's site just like in the guide.Flashing goes to 96% then the computer restarts,but I've readed it's normal with MSI mobo.I'm using adapter for PCI-e and into it is m.2 ssd. I'm thinking maybe the adapter it's broken.I will try to do that again but I've tried like more then ten times,maybe I'm doing something wrong.

Edit:
I've done everything again like in the guide in first post.
Flashed the modded bios through MSI M-Flash.
Windows 7 doesn't see the m.2 SSD and it doesn't show up in the bios.
I'm attaching the modified bios into this post.
