Hey! Just wanted to say that thanks to you my Asus P8Z77-V LX now works perfectly with MVMe!

Hi Fernando - thanks to you and all the forum members for continuing to support this excellent resource. I hope you may assist me with a couple of questions:

Q. After reading and following the forum advice I have successfully managed to insert NVMe module into bios v1903 for my Asus Maximus V Gene and install Windows 10 and boot etc. I originally inserted NvmeExpressDxe module (which works) but now see that there is a more recent NvmExpressDxe_4 module. Using MMTool 4.50.00.23 is is OK to remove the old module and then insert the updated module? If yes, what may be the benefit?

Q. I also have an Asus HM87M-E and when I load the bios (v2201) into MMTool I note the following modules are present Nvme.ffs, NMVINT.ffs, NvmeSmm.fss. I cannot get the system to boot from my PM981 - so should I insert the NvmExpressDxe_4 module so that there would be 4 nvme files in the bios or should I remove the 3 existing files and replace with just the NvmExpressDxe_4 module?

Q. Does module PciExpressDxe (present in the Maximus V Gene bios) need to be added into the HM87M-E bios or is it not needed to boot from PM981. What is PciExpressDxe actually needed for?

Thank you to anyone who can offer me some assistance.

Someone solution with the GRYPHON Z87 asus bios, who can send me the file to update the bios? Board link https://www.asus.com/us/Motherboards/GRY...pDesk_Download/
I thank you for trying everything. Thank you

Thank you for your swift reply Fernando..

1. I will try to 'Replace' the original NVMe module with the latest NvmExpressDxe_4 and test.

2. You are of course correct, it is Asus 'H87M-E' and I too have re-downloaded and checked and find there are no NMVe modules in the original Asus bios - I believe I must have loaded one of my test bioses in error! I have succeeded to insert NVMe module in bios but can you suggest the best way to flash it as CAP file will be protected - should I better to extract the ROM, modify it and then use AFUWINx64 to flash the updated ROM back?

3. Thank you for clarifying that the PciExpressDxe module is not needed for PCIe booting.

Thanks for your reply

I already modified the bios file I get an error "the bios image model does not match the rom memory of the installed bios"

I don't know how to perform the update

Fernando
It doesn't let me update for security too. I think it is when saving the project because I do everything well according to the manual.

OK, so my results of testing are that when the NvmExpressDxe_4 module is inserted into the bios for the Asus H87M-E then the system locks up every time CrystalDiskMark (v6 or v7) is run. I have a fresh and fully updated Win 10 1903 Pro x64 install and have tried with the standard MS NVMe driver as well as various Samsung NVMe drivers including latest v3.2 all with same result i.e. = system lock up when running CrystalDiskMark.

Finally, after replacing with the original NvmExpressDxe module (from circa 2015) everything works fine...I have seen there are maybe 4 versions of the NVMe module but the original one seems to work best for me.

My Z77 Maximus V Gene is also running the original module but not sure I will update it at present.

Hope this may help others so they don't spend hours trying various configurations as I did :-)

Also, I found that easiest way to flash the 'locked' bios for my Asus H87M-E with a 'modded' bios was as follows:

1. Download AFUWINX64 tool (v3.05) into a folder on your boot drive e.g. C:\AFUWINX64
2. Download the latest original 'clean' bios for your system e.g. Bios.cap into C:\AFUWINX64
3. Download MMTool (v4.50) into C:\AFUWINX64
4. Download the NVMe module you wish to insert e.g. NvmExpressDxe.ffs into C:\AFUWINX64
5. From CMD prompt run AFUWINX64 to extract backup copy of your 'existing' bios into C:\AFUWINX64 (use... AFUWINX64.exe Extracted.rom /O )
6. From CMD prompt run MMTool and load in the Extracted.rom file
7. Next browse and 'insert' the NVMe module into the CSMCORE section of the Extracted.rom file (as per Fernando's guide)
8. Then save a copy of the modded file e.g. BiosNvme.rom into C:\AFUWINX64
9. From CMD prompt run AFUWINX64 tool to flash your system with original 'clean' bios you downloaded (use... AFUWINX64.exe Bios.cap ) THEN...
10. From CMD prompt run AFUWINX64 tool to flash your system with the 'modded' bios you made in MMTool (use... AFUWINX64.exe BiosNvme.rom /GAN )
