I was able to delete the Sata Driver and insert the compressed NVMe module.

The problem is I can't flash the modded BIOS.

using Asus winflash with /nodate gives me an error "invalid BIOS File".

I tried finding the ASUS USB Flashback procedure, but there is no documentation or known method to do it (the previous ctrl+home with bios placed on root directory doesn't seem to work on newer asus models).

I also tried the Flashing modified AMI Aptio UEFI using AFU. Tried AFU modified.rom /P /B /K but it gives me an error "ROM file size does not match existing BIOS size."

I also tried the command AFU modified.rom /GAN but I got an error unknown command.

I also tried the AFUWINGUI.exe with option Program All Bocks and Do not check ROM ID but I still get "ROM file size does not match existing BIOS size."

I also tried the uncompressed NVMe module and insert it both as is and compressed but it didn't made any difference.

EDIT:
I also tried the FTK from -->hardforum.com<-- but I get Error 280: Failed to disable write protection for the BIOS Space!
my BIOS is the oldest one.

Chipset support 8 pcie lanes, which can be configured to 4x1 and 1x4. They are only 2.0, but can still get ~2GB/s in x4 config.

Oh, and i couldn't care less for obsolete x79.

---

Theoretically ~2GB/s. 2GB/s is just the beginning of NVMe.
Please do not forget, that PCIe 3.0 is requiered for NVMe.
PCIe 2.0 is not supported and will never be.

I didn't want to insult you, I'm sorry. But If you want NVMe for Z77/Z87,
you really NEED PCIe 3.0. So you have to cut down GPU bandwidth or use the iGPU,
depending on your mainboard.

X79 is still a great platform. It's outdated, you're right.
But from this POV, Z77/Z87 are outdated, too.
BUT neither of them have reached EOL status.

I was now able to flash the modded BIOS with the NVMe module thanks to the advice I got from Asus ROG forum.

It turns out I have to dump the existing BIOS on the machine so it will remove the CAP header, I was successfully able to flash the modded BIOS.

The problem is this NVMe mod did not work with my Samsung SM951 NVMe.

I tried both the compressed and uncompressed NVMe module but it didn't made any difference.

I also tried to remove the EFI LAN driver instead of SATA driver, but it also didn't made any difference.

I also tried the newest BIOS for my machine and mod it to have the NVMe module, but that also didn't made any difference.

I made sure to select the option to program all blocks when I flashed the modded BIOS.

I also dump the modded BIOS to verify that the NVMe module is present after I flashed it.

All I got was blackscreen after I power on the machine. I also tried to remove my SATA SSD and just leave my SM951 NVMe, but that didn't made any difference.


In conclusion this NVMe mod doesn't work with Asus G751JT


EDIT:
After flashing the modded BIOS with NVMe module, on the BIOS screen there is no NVMe setting like my desktop computer.

Hello to everybody.
Good news for all owners of Asus X79 Deluxe.
Today Asus has released bios 4805 with NVMe support for this motherboard. They use the three modules tested at the beginning of this thread. But for Sabertooth X79 there is not updated bios.

Good luck.

Hi Fernando, I could really use your help.

Had tonnes of problems.
I followed the instructions on the front page, as well as on various other pages in an attempt to get my Intel 750 400gb pci-e ssd to be bootable on my Asus P8Z68 and install win10, but I am having epic problems.

I was able to successfully insert the required FFS file, I was able to flash it, and once I did that, the sad finally showed up.
But only as "pata ss:"
That's it.

I tried to install win 10 using USB, and it says that the partition can't be installed on and is not bootable, and asked me to ensure disk controller is enabled in bios.

I used the "load driver" button and loaded the Intel drivers and it was able to load the initial setup of win10.
After reboot though, even if I press f8 and manually select the new pata ss option, it goes straight to a screen that says "

your pc/device needs to be repaired
The application or operating system couldn't be loaded because a required file is missing or contains errors.

File:\windows\system32\winload.exe
Error code: 0x000000e
"


At one point you said that you put the bios into "optimized defaults" and "efi compatible".

Optimized defaults for me worked fine, but when i changed to efi compatible, my computer no longer booted. It would just sit at a black screen, and afte a few minutes would go to a black screen with a single blinking cursor line.

I had to reset my bios to factory defaults by using the pin method on the physical bios. I've had to do that twice now.

No matter what boot settings i use, bios settings, or drivers loaded during installation, i always run into that recovery image above.

When I do the first half of the install, it reboots, i don't have a "windows boot manager (Intel 750)" option, I just have "Pata SS:" and when I select that, it doesn't continue the install, it just goes straight to that error.

I've had to rebuild my BCD about 3 times also.

Can you please assist?

I feel like I must be so close...

It would also be helpful if you wouldn't mind telling me how you partitioned your drive, GPT/MBR etc, for when you finally got it to work.
Thanks so much!

@Fernando :

Hi Dieter,
Thanks for the reply, really appreciate it.

Did you redo the previous BIOS settings after having flashed the modded BIOS?

---

I suspect, that you didn't unplug all other storage devices except the NVMe supporting SSD and the USB Flash Drive containing the bootable OS image. That it is important, because only this way you can be sure, that the boot sector will be created within the NVMe SSD.

---

Thanks, I will try this.
I remember when SSD drives first came out a decade ago (or whenever) this was the only way I could get the boot sector on that too, looks like we've come full circle.

I installed the OS in UEFI mode, that means, that the OS Setup created a GUIMODE Partition Table.

---

This is the one and only thing I have not understood in all the posts and threads i've read in this. UEFI mode. I see no reference to UEFI mode anywhere in my entire bios for my ASUS p8z68-v pro gen 3.

I will try isolating the drive and see how I go.
I suspect once I plug the old SSD back in, which is active, with the previous boot sector on it, that i will have boot issues, but that's fine, I will just edit the BCD and remove that entry.

Here goes!

Thank you kindly for your assistance.
Greatly appreciated.

What about your graphics adapter? If you use a discrete graphics card, maybe the needed EFI GopDriver is missing within the BIOS.
In this case I recommend to remove the discrete graphics card and to use the CPU integrated Intel HD Graphics adapter.

---

That's interesting... unplugging my GPU, I had never considered that.
Then again, I'd never heard of Gop until reading this thread. At what point would I put the GPU back in?

You should see the word "UEFI:" as prefix of the listed bootable USB Flash Drive name.
Precondition is, that you have
a) formatted the USB Flash Drive with the FAT32 file system and
b) have chosen the option to create a Guimode Partition Table, when you created the bootable USB drive (for example by using the tool named Rufus).

---

Ar, there it is!
My usb flash disk had been formatted with MBR, not GPT.

wunderbar
I'll give these a try shortly as it will require some unplugging. I'll have to look into what Gop is too. I assume this is where the computer uses onboard graphics to display post/boot info.

You can try to reinsert the discrete graphics card after having completed the OS installation in UEFI mode, but maybe you have to make sure, that the BIOS of the graphics card contains a working EFI "GopDriver", which is the EFI variant of the VBIOS module.

---

@Fernando :

One more question if I may.
The Intel 750 drive, did you pre-format it before using it, and format it as GPT, or leave as MBR. I'm assuming GPT, given the flash drive?

Well I spoke too soon.
My other drives don't even appear on boot anymore or in windows.
I'm only mentioning it here, incase this is a common problem/consequence of doing this workaround.
If it's not, then that's cool, it's up to me to fix, and I will.

Cheers
