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

Christian

Found it! for those who would tread into this post in the future... http://forum.notebookreview.com/threads/black-screen-when-trying-to-go-into-bios-or-stuck-at-msi-scr...

[asusyajota]

I have thoroughly followed the guide step by step and also have checked the line 184 text to be exactly same. But my bios or windows setup still can't detect samdung 860evo m.2 ssd. Could someone shed some light on me? 😕

[bugme-not]

2 questions:
1. Does this mod provide performance or stability improvements to the stock ssd?
2. Why is the bios mod not extended with the latest microcode, lan firmware, etc..?

Hi,

Thanks for the instructions. I've ran into some issues, and I wonder if anyone else has had similar issues - I'm running out of ideas on what to try next.

My issue is that the laptop does usually not even boot up with the M.2 drive installed. The screen stays blank and after some 15 seconds or so, the machine powers off. Usually I cannot even enter the BIOS even though I'm hitting F2 as fast as I can after the boot.

I've tried flashing the bios (both version 3 and 4 of the NVMe efi), I've tried disabling fast boot and secure boot, and I've also tried enabling and disabling the CSM. Nothing seems to help.

I tried incorrectly cloning the old drive instead of doing a fresh install - but I then installed the drive to a desktop computer and removed all of the partitions. Still, nothing seems to help. I cannot also boot even from a DVD or an USB disk. But the weird thing is, at first, I was able to even clone the old drive with no issues, and I've also once been able to boot half-way to windows (but the computer then shut off in the middle of the process).

Like I told in the subject, my M.2 drive is 1 TB 970 EVO plus (so NVMe, not SATA), and I've ROG-G751JT. Though the computer didn't come with an M.2 drive installed, it does have the connector, and as can be seen, it is even wired. But I'm not sure if it has been deliberately made unusable, or if I'm just having some issue.

firstly in bios
xhci pre-boot mode = disabled
try later.
