ROG G751-JY BIOS 211 NVMe Upgrade Guide Step by Step

[chris_tronic]

Hello volks,
this guide was developed on the ground based work of Fernando in the WIN Raid Forums.
He developed the NVMe Support and the update procedures. Im very thankful and proud of Fernando's work.
Without it, we would never have NVMe support on our older generations Notebooks..

I recently modded my BIOS and now it supports the NVMe Protokoll.
I want to share some experience I made during modding my BIOS,
so that anyone who owns the G751 with an M.2 slot should get a NVMe drive to work.

I dont take any responsibility if you make modifications and somehow brick your BIOS.
I strongly recomment to decide yourself if you want do the BIOS Mod or not.

Its not quite difficult to mod the ASUS G751-JY BIOS. I will give you an easy Guide you can follow step by step.
My System is a G751-JY with 24GB of RAM Georce GTX 980m 4GB and Windows 7 prof. 64

OK, lets start.

What you need:
- actual BIOS Vers. 211 / if not yet installed, please download the Update from ASUS support and install it yousing Easy-Flash in the BIOS.
- AMI Firmware Updater (afuwin64) from AMI for Aptio 4
- MMTool for Aptio 4
- UEFITOOL_0.2.2.1
- EFI NVMe BIOS Module

You can find the actual downloads on the win-raid forums.

This guide was also done with the ground based work of fernando.
Please ask him for further support

1. First of all, downoad all the needed files into a new Folder and Name it "BiosMod"
2. Now we are going to make a copy of the present BIOS using afuwinx64. Start the AFUWINGUI

3. Hit the save Buttom and store your actual copy of your BIOS in a seperate Folder and name it afuwin.rom
4. Copy the afuwin.rom (your EFI BIOS without Capsule) to the MMTOOLs Folder
5. Start MMTooL and Load the afuwin.rom Image

6. Click "Create Report" and close MMTooL.

7. Now open UEfiTool_0.2.2.1 and load the afuwin.rom image by clicking "File" and "Open Immage file" and select
aufwin.rom

8. Now that you loaded your BIOS in Uefitools hit the "File" Buttom --> "Search" select "Text" and enter DXE in the searchfield

9. Hit "OK" and doubleclick at "interface section at offset Ch"

10 . Scroll down to the LANDriver DXE driver and click the right Mouse buttom and hit "Insert After..."


11. Select the "NvmExpressDxe_3.ffs

12. Now you have insert the DXE NVME driver Module in the free memory space below the LanDriver DXE Module. Now you Click "File" and "Save Image file..."

13. Save the new romfile and name it 211nvme.rom

14. Click "Yes" for Open reconstructed file? and parse again if the NVME Module is correctly installed between the LanDXE_Module and the free Space

15. Copy the new 211nvme.rom file to the MMTools Directory.
16. Start MMTool and load the new 211nvme.rom and click create Report. Close MMTool

17. Now you can open both the old afuwin.rpt Textfile and the new 211nvme.rpt Textfile and compare them.


18. Compare the afuwin.rpt and the 211nvme.rpt and you should get the same Text as I have


19. Now that we have checked everything, we are going to flash the new BIOS
20. Open afuwingui hit "Open" and select the "211nvme.rom file" Carefully look at the Lenght of the File it should have exactly 6.144KB as your afuwin.rom also.
Maybe the length could differ from BIOS to BIOS but i think it should be that value.


21. Now we are ready to Flash the new BIOS. Attach your powersupply and close all unneeded Programs
22. Hit the "Flash" buttom and enjoy your computer gets upgraded with NVMe support.


Now that we programed the new BIOS, you can attach a new NVMe SSD at the M.2 socket.
Notice: there is no Drive Listing in the PCIe SSD field or it even disappeared in the BIOS, but dont be afraid.
If the NVMe SSD is bootable, you should get a BOOT Option like I have: Windows Boot Manager.

Here is an overview of my HWInfo:



I hope you find this Guide useful. IF so, you can leave some comments.
Thanks also to the WinRaid Forum for Supporting me with the DXE Drivers.

If you want, feel free to contact me:
I can create check and send the modified 211nvme.rom Bios File file to you, if you send me your saved Bios with afuwin (valid only for G751having a PCIe x4 M.2) Than you only need to Flash the new Bios with AfuWin64 without to be afraid bricking your G751.
Just send my an E-Mail to: chris-tronic@gmx.de

[And again, if your unsure if you wanna do the Flash, better do not. I will not be responsible for any damage.

Have Fun

Hello, I just purchased a G751JT-CH71 with an m.2 connector, and I just received my Samsung 960 Evo NVMe SSD. I would like to attempt this procedure, unfortunately all the aforementioned links are dead. Might I find them anywhere else?

I would not proceed without getting into contact with the original Poster so far as I know this is the only thread on this subject!!

Alrighty, I am have modified my BIOS and I'm ready to risk flashing. I tried already, but the build date is "too old"
It's the same version I currently have installed, can someone help me get passed this final hurdle?

@ all visitors of this thread:
The method how to get full NVMe support for all systems with an AMI UEFI BIOS has been developed by me already in 2015 and layed down within the start post of >this< thread.
There you can find the download links to the latest/best versions of the NvmExpressDxe BIOS module and of the UEFITool, which is suitable to get it inserted.

Any ideas if this is compatible with it http://www.dx.com/p/pci-e-v9-5-exp-gdc-m-2-m-key-version-laptop-video-card-docking-station-463295?Ut...

how exactly does pluggin ext-GPU into the M.2 is similar to connecting a storage device and modding the uefi to support NVME ( which is the topic of this thread ).

you've already made new thread with that question - NO NEED to SPAM other threads.

Thank @chris_tronic so much!!!!
I updated my ASUS G751JT with Samsung 960 EVO 1T, it boots and works!

And.... interesting problem where running afuwinx64 gui literally freezes the OS. Like a kernel level crash.. minus the actual crash....
afuwin tool downloaded from, https://ami.com/en/download-license-agreement/?DownloadFile=Aptio_4_AMI_Firmware_Update_Utility.zip, .. so technically different/latest from @chris_tronic's original version... but that shouldn't matter. (it's version 3.09.03.1462).

Great it's not just me going crazy.
And also means not anomalous to just me... good news.

Yet you got somewhere down the path of performing the mod on this post earlier on in the thread, no ? https://rog.asus.com/forum/showthread.php?99677-ASUS-G751-JY-BIOS-211-NVMe-Upgrade-Guide-Step-by-Ste...
So you managed to run afuwin ?
