You cannot flash the modded BIOS the normal way into the BIOS chip of your ASUS laptop because of the ASUS specific BIOS in-box protection. You will have to use the AFU Utilities according to >this< guide written by our BIOS Guru CodeRush.

Well the good news is I do have a z97-Hero at home that isn't NVMe but does have a UEFI BIOS. I have an AHCI M.2 running in the slot at only x2. I figure if i can get NVMe working on it i have a PCI-e to M.2 card I can put in my other x4 slot and may be able to get the NVMe working on that desktop machine fairly easy. At least the BIOS can be flashed much more easily.

Concerning the AFU BIOS flash write up. If I understand it correctly there are different versions of the program. As I have WIn 10 64-bit, i'd use the afuwinx64 folder with afuwinx64.exe as the file I'd be using.

It says to boot up on a DOS boot disk but wouldn't a command prompt from a win 10 boot disk work just as easy? From there I would use the command afuwinx64.exe "MyBIOSnam" /P /B /K and that should be it?

I'm thinking this is the procedure that will do the trick. Is this about right? Thanks.

Welp I figured it out and got the Modded BIOS installed through that link you offered. Unfortunately, I can't get the UEFI boot option for my USB drive. I did remove all other drives and only had the Samsung 950 Pro installed. Reading in a few other of the threads here it seems that I'm not the only one who had tried (and was unsuccessful) with the Asus G751JT.

On the plus side I have learned a bit more and may try it with my Asus z97 mb soon. :)

@Fernando
The 2015 and 2017 versions are identical. They both share the same code. If you found some differences then this could be due to the fact that you compared compiled versions. So if maybe a newer compiler or other optimizations were used they don't have to share the same compiled end result even if it was compiled from the same source.
I am going to test the new NVMe module with my 960 Pro as soon as i am back home...

Flash with a USB stick using RuFus (FreeDos option) and use AFUDOS /GAN. Never had any problems with this solution. If you fucked your BIOS in the first place cause something went wrong .. well .. why are you trying it anyways? Take the risk (normally you will do this on an old system :p) and have some fun if you really need to switch BIOS chips. This will just make things more interesting and you will learn something :)

Thanks for testing the different drivers! Which GCC version did you use? I also think that you should test this option with some real world benchmarks like using Premiere Pro, copying, compiling, etc... something that has a real value instead of a synthetic copy benchmark thats only good for a rough comparsion between drives.

Also: What do have in the works? ;>

Correct me with i am wrong: but as far as i understood the NVME efi driver is only used at boot time. As soon as the OS loads its driver this one takes over and handles "everything". So the DXE is only used at boot time and to intialize the drive?

Thanks I appreciate it. I was using Visual Studio 2015. Its always tricky to compile these source files because theres so many compatibility issues with each release and each version of compiler. I almost gave up because after I end up with like 5 different compilers all stepping on each other. As far as what I am working on I would rather not say at this time except its really cool. Anyhow thats interesting what you say about the driver level optimizations. Was worth a try though.

This machine is two years old and I don't use the laptop for much. I have an extra Samsung 950Pro lying around so I thought I'd give it a go.

I was able to use the AFUwinx64 from a command prompt and flash the /p /b and /k. All copied over with no issue and it is showing the correct version and size of my modded BIOS. Sadly I just am not seeing the option for UEFI for my USB. So either I modded it wrong, I didn't copy it over correctly (though it looked like it did from what I saw in the other topic) or something else happened.

I'm home now and I'll give the FreeDOS a chance and use the /GAN option.

**EDIT** Gave FreeDos a shot. It looked like everything went through but booting up I see my Sandisk USB but nothing with a UEFI BIOS option. I see the Samsung 950 there but without that UEFI option I can install onto the drive but won't be able to boot from it. :( But I gave it a go.

The BIOS modding procedure itself is safe, the only risky part is the flashing of a not correctly modded BIOS. Nevertheless I don't know any user, who has bricked his mainboard by flashing a BIOS, where just an originally not present EFI module had been inserted.If you are unsure regarding your BIOS modding result, you can attach the modded BIOS as *.zip or *.rar archve and we will do a look into it.

I have a IPISB-NK (Lavaca3-SB) motherboard from HP in a couple AIO systems. I believe it is AMI UEFI Aptio IV H61 chipset... I have the mini PCI-e slot available on it. 1 is a half mini for the wifi card and the other is the regular mini pcie usually used for a TV tuner card that I will never ever use... Is this mod going to allow me to use the NVME SSDs in that slot? I am only getting around 250MB/s on my SATA Samsung 850 Evo 1TB SSD (I guess its limited to 3Gbps in my system... PCIe is Generation 2 speed...., but I think my MXM is Generation 3.... but maybe that is just the graphics card itself)... My current bios is attached.... Or is this for the actual SATA port? to make it SATAe?
