> As far as I understood, you should see after reflashing a ''PATA SS'' device in the boot section, if you do, then you're on the right path.

Thanks, I confirmed NVM Express driver is loaded correctly using EFI shell.

Although the 'PATA SS' boot device is missing :(

Hey guys, I'm OK with the thing :)


The problem was my USB stick as it seems, I borrowed another one, formatted it via Diskpart, and there I am.
Followed this guide:
https://www.easeus.com/partition-master/...-using-cmd.html

The only strange thing is that it was flashing for a good minute or so. The Flashback ROG Connect LED was blinking not 3 times as it should, but more than a minute. I thought that I bricked my MoBo again but everything went smooth in the end.
Installin' a clean copy of Win10 on my new 970 Pro now

@devhirano Please check carefully your modified bios file and the USB. You must have the new device in the boot department, otherwise you won't go any further.

Thanks a lot, Fernando, you are a cool guy indeed

Thanks again Fernando for all your patience and work.

It is crucial to have correctly formatted USB bar, it can happen that it has a UEFI partition or something. All this should be checked carefully before flashing the modded bios.
That is what I understood from my story with getting this to work. Second is the correct settings within bios (fast boot and so on).

Fernando, after installing windows, should I set the Fast boot and the rest as it was before?

You can try to change all these settings, because it is no problem to reverse them (if it doesn't work as it should).

Hello, I'm back with updates...

I have been using the NvmExpressDXE_2 module since March 2017: [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS (113)
But after releasing the NVmeExpressDXE_4 module I was not able to update the BIOS with USB FlashBack button anymore.
Today, I used my CH341A USB EEPROM programmer and now my ASUS P9X79 PRO has a new BIOS with the latest NvmExpressDxE_4 module.

I done some tutorial how to unbrick MeeGoPad T07 ComputeStick here: http://forum.x86pad.com/t/guide-how-to-u...b-and-other/926
Flashing BIOS on ASUS motherboards is even simpler, all you need is:

1. CH341A USB Flash programmer: https://www.ebay.co.uk/itm/262731801596 (£4.23)
2. CH341A Programmer Software v1.29: use Google!
3. CH341A Driver v2.2.2009.6: http://deviceinbox.com/drivers/845-usb-epp-i2c-ch341a.html
4. PLCC IC Extractor Tool: https://www.ebay.co.uk/itm/273066030226 (£0.99)
5. UEFITool v0.25.1: https://github.com/LongSoft/UEFITool/releases
6. (Optional) For beginers, I suggest you buy a clean EEPROM chip: W25Q128FVIQ (approx. £5.00)


0. Go to your ASUS UEFI and save all OC profiles on USB stick!!!
1. Prepare a modified BIOS for your motherboard - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS
2. Convert it from .CAP to .ROM/.BIN by opening in UEFITool, then right-click on "AMI Aptio capsule" and select "Extract body", then save it as .ROM or .BIN file.
3. Use CH341A Programmer Software to flash your BIOS.
4. Replace the original BIOS from the motherboard with a modified one using PLCC IC Extractor Tool.
5. Run your computer and restore your OC profiles from USB stick*

* You can restore OC profiles only within the same version of BIOS - for example OC profilles from Official BIOS 4801 will work on a Modded BIOS 4801.

After updating the NvmExpressDxE_2 module to NvmExpressDxE_4, I noticed the correct display of the M.2 drive name in UEFI.
Are there any other differences?

NvmExpressDxE_2 (left picture) and NvmExpressDxE_4 (right picture):

I've tried both the NVMexpress4 full and small and I'm not able to get the server to boot after flashing the modded BIOS on my X9DRi-LN4F Supermicro. I'm flashing via IPMI and it seems to complete ok, but then doesn't reboot. I'm able to then flash back to the original BIOS and the server boots ok. I saw on here others had luck with this same motherboard. Do you have any advice on what I could be doing wrong and if flashing via iPMI is perhaps the issue? Does anyone have a BIOS they modded successfully for this motherboard they would be willing to share ( I'll pay for it if necessary) ? I've attached my modded BIOS in hopes of you checking to see if I did this right. Thanks!

Also, THANK YOU Fernando for taking your time out and for YEARS now updating this thread to help people!

I looked at what driver version was posted for your board, because it was quick and often the same as ME FW on older setups, but not always.

Thank you Fernando for the warm welcome, glad to be here.

I see what you mean now about the 2 raw DXE drives. I'm going to give this a try now and see how it goes. Thanks again!

Hi Fernando I tried that and it did the same thing unfortunately. I tried a few different places as well just in case but the server wouldn’t boot afterwards so I had to flash it back.

Would you be willing to try modding the BIOS and attaching it so I could give it a try? I would be more than happy to pay you for this and even give IPMI access if necessary. I’ve tried everything I know of and feel defeated. Thanks
