Hello! I have ASUS Maximus VI Formula. I followed the instructions and modified 1603 BIOS with NVMe_4 but cannot flash it. It's just refusing flashing through official BIOS Updater and EZ Flash 2. Can anybody help?

How did you flash it?

@treeshka 1) You need Win7 SP1 compatible driver for NVMe support (download it from win-raid NVMe driver thread or from Samsung website), which has to be added manually on "select drive for installation stage" - simply click "add driver" in bottom left side of installation window. If you can't find it, you have to use generic driver, which means updated installer for NVMe support (adding USB3.0 drives is
@AAKEE ASUS BIOS flashback needs FAT32 pendrive, and correct file name for update to work (in my X79 Sabertooth case, it was SABERX79.cap).

Hi all, my name is Gabriel and I have an Asus N751JK and a Samsung 970 EVO. Windows 10 detect the HDD and I'm able to install Windows on the 970 EVO but Windows dosn't start becouse after reboot, bios dos not detect the SSD.
I followed the guide in every part but when I use winflash it tells me that the bios is not valid.
I tried using the same name and extension as the original file but got the same result.

Has anyone had the same problem?

Thanks a lot!

@raven1234 - See this guide - [Guide] How to flash a modded AMI UEFI BIOS
Or this one for AFU - [Guide] Flashing modified AMI Aptio UEFI using AFU

Did you already flash, or not? Sounds like yes, since you say not detected, then sounds like you didn't flash because BIOS not valid.
That can be due to Security issue which is common with mod BIOS, or mod fail, either could be, you need to post your modified BIOS so someone can check which is the cause.

I renamed it to M6F.CAP and it flashed perfectly. Thanks

Lost_N_BIOS Thanks a lot for your help.
Actually no, I tried to write the BIOS but without success, winflash say not valid BIOS.

I will follow the guide you suggested me and I will post the modded BIOS.

Verily, yesterday I thought that the problem is that my BIOS is not suitable (It's an American Megatrends of 2012 like the example pic in attachment), for example in thestructure there are not "Intel Image" or "Bios Region" line like in the example....

Thanks, I'll do tonight when I come back home

Winflash is not a tool I suggested, or would use?
Yes, I downloaded your BIOS earlier and looked inside before replying, it's AMI as you mentioned, and uses Intel HM86 chipset. You can use AFU or Intel Flash Programming Tool (FPT)

Post your modified BIOS here before trying anymore flashing, in case there is something wrong with the BIOS mod, I'll check and see if it looks OK

Thanks! First I'll give you time to take a look on my modified Bios.

Later I will use AFU as you raccomend with [Guide] Flashing modified AMI Aptio UEFI using AFU

Yes, please upload your modified BIOS and I will check it over.

write please the instructions for the firmware of msi h97 gaming 3 motherboard

@raven1234 - thanks! First, you have to remove the BIOS from the capsule container, then modify. Do not put back into a capsule (Nor rename .cap)

If I was you, I would start over and do the mod again, with the below first if you didn't do that the first time.
Because I am not sure, if you extract the rom now, if checksum or something else needs corrected in BIOS after the mod, which UEFITool already did, but if contained in cap file that would be part of the checksum making it wrong to extract after the mod.
Hope you get what I mean. I think it's safer to redo the mod, extracting the rom first from capsule, insert the NVME module, then save/rebuild and then flash.

Then flash as I mentioned. If the NVME mod is all you did, then it looks correct to me, except for the above concerns.
Open the .cap file in UEFITool, right click AMI Capsule file, and choose Extract body.
Then, that file is what you want to flash with using methods for flashing modified BIOS, and what you should do before modifying BIOS.

You can flash with AFU or FPT, How to with AFU Is in the guides linked above

Here's how with FPT (Intel Flash Programming Tool) - FPT - >> FPTW.exe -F N751JKAS.205.M1 -savemac -BIOS
You need to use FPT from version 9.5 system tools - https://mega.nz/#!CdFUSaxb!DkpSh5cUQN7hs...IurQ18sGI_O3KR4
