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

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.
https://www.win-raid.com/t871f50-Guide-How-to-get-full-NVMe-support-for-all-Systems-with-an-AMI-UEFI...
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
71102
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
71103
6. Click "Create Report" and close MMTooL.
71104
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
71105
8. Now that you loaded your BIOS in Uefitools hit the "File" Buttom --> "Search" select "Text" and enter DXE in the searchfield
71106
9. Hit "OK" and doubleclick at "interface section at offset Ch"
71107
10 . Scroll down to the LANDriver DXE driver and click the right Mouse buttom and hit "Insert After..."
71108
71109
11. Select the "NvmExpressDxe_3.ffs
71111
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..."
71112
13. Save the new romfile and name it 211nvme.rom
71113
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
71114
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
71115
17. Now you can open both the old afuwin.rpt Textfile and the new 211nvme.rpt Textfile and compare them.
71116

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

71117
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.

71100
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.
71101

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:

71154
71155
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

Regards

Christian Karbe ( Informatic / Computer Enginneer)
[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,

Yes, I have an NVme Adata M.2: the sx6000 lite and it is working perfectly on my G751JY after following the instruction in this thread and those that are found
at
https://www.win-raid.com/t871f50-Guide-How-to-get-full-NVMe-support-for-all-Systems-with-an-AMI-UEFI...

The instructions that are here are more specific to the G751j series so I mostly followed the ones in this thread. The files that I used I was able to download right off this thread, don't quite remember who is hosting them. I did the mod with the asus 213 bios already installed and the only difference aside from that was I injected NvmExpressDxe_4.ffs in the bios not NvmExpressDxe_3.ffs.

It is possible, Kliszczak, that you need the latest NVme driver to get optimum performance. You can get that at the win-raid site.

Oh my mistake, you did use the latest NVme driver. Ok well you should be getting upwards of 1600 reads and 1200 writes, the limit is set by our motherboards. What laptop do you have? What drive are you trying to install?

Hi folks,

Specific-BIOS-modding-problems-with-an-ASUS-ROG-G-JY-notebook.html

If you want an updated bios go post with the link above . Don't use someone else modified bios , since modified bios is done from your own backup to avoid loosing precious informations like serial etc...

Cheers

All credits goes to win-raid forums (feel free to donate to help them or not) and especially the great Lost_N_BIOS .

What is updated in bios :

- EFI and OROM IRST updated to 14.8.2.2397 (use Intel Rapid Storage Technology driver 14.8.16.1063)
- Microcodes updated (only for CPU i7 - 4710HQ)
- NvmExpressDxe_4 mod inserted

This bios is v213 for G751JY with I7-4710HQ, don't use it if you have anouther CPU.

Cheers




am new to this bios update so could i ask is the bios you have posted on this link ( https://www.win-raid.com/t5004f16-Sp....html#msg83470 ) already fully modified with everything needed to use an nvme drive...Do i just need to download your bios and flash it then install a 970evo nvme . Does it matter what bios i have installed at the moment or do i need to update it first before flashing your bios ? . I have a G751JY with I7-4710HQ laptop with BIOS Version/Date American Megatrends Inc. G751JY.208, 23/04/2015

You must first update to the official 213 bios (so you will have the most recent one) than make two backups of it and apply the modifications to one backup file.
This way you will not lose some important settings like your NIC MAC address.

The necessary tools are here: https://www.asuswebstorage.com/navigate/a/#/s/EE03224491694BF68D089F6623B255434

You can get the most recent "NvmExpressDxe_4" module here: https://www.win-unattended.de/Benutzer/Fernando/BIOS-Files/non-Intel/NVMe%20Modules/NvmExpressDxe_4....

You should follow the guide in this thread (remember that you may do it at your own risk).

When applying the updated BIOS file use these settings in AFUWINGUI:

Hi, I modified my earlier post. Don't use someone else modified bios ! Please read it again.

Hi everyone! Back in November I successfully completed this mod in about 30 min, thank you for this super helpful post! I have a (small?) issue now as I recently updated the bios from the modded 211 to the new 213 bios, and after completion the ssd I was using is no longer recognized on startup. I can however insert a Windows 10 disc and install windows onto the ssd but while trying to start Windows on the ssd itself without the disc, there is no bootmgr.

Is there a way to revert back to the previous setting before I did the bios 211 mod? My reason is that I have upgraded to a new laptop and now want to sell this one with default settings. Thanks in advance for any help given!

You can mod the 213 the same way you did 211. I recently modded my brothers laptop with bios 213 (NVMe 4) and it worked. Make sure to use old Aptio 4 as the new one freezes in the laptop. That's the only issue I encountered. here are the files required link (not mine):
https://www.asuswebstorage.com/navigate/s/EE03224491694BF68D089F6623B255434

You don't need to revert back to old bios as it is basically worse than the modded version. here is a link for the old versions if you need it. https://www.asus.com/us/Laptops/ROG-G751JY/HelpDesk_BIOS/

Hello Volks,
im very happy so many people used this guide for an upgrade. The need for a slow and expensive AHCI SSD vanished.
I dont know if I will break some rules, if I put all the necessary files into my dropbox and share them here.
Maybe i get prosecuted if I host them. Does anybody have an Idea if its legal or not?

Thanks
