Fernando, is it important to disable Secure boot like it was said above, by saving the profile and disabling PK thing? And then turning it on?
I'm missing sometyhing here for sure...

@Fernando:
Fact is that I did like the instruction says - inserted a formatted in FAT32 SB 2.0 bar with the modified bios alone, inserted it in white USB port, pressed the ROG Connect button for several seconds until it stopped blinking and then restarted the PC.
What is wrong you think? Sorry for offtopic and thanks for your help.

Will try another USB stick. The file is named properly - R4E.CAP

Fernando, can I ask you a favor to check this modified bios if it is OK? It's linked from ROG forum.

Thanks a lot in advance.

@alster:
The NVMe EFI module has been inserted correctly, but it is not the module, which I recommend to insert ("NvmExpressDxe" is outdated, the latest/best is named "NvmExpressDxe_4").

Maybe I'm in same situation on @alster, I cannot see the NVMe device as boot.

Motherboard : ASUS Maximus Gene V (not IV), https://www.asus.com/Motherboards/MAXIMUS_V_GENE/
Inserted BIOS: tried both NvmExpressDxe_4 and NvmExpressDxe_Small
M2.ssd : WDS500G2B0B , https://www.wdc.com/en-us/products/inter...tml#WDS500G2B0B
PCI-E slot : EASYDIY PCI Express M.2 NGFF PCI-E SSD to PCIe 3.0 x 4 , https://www.amazon.co.uk/EASYDIY-Express...0/dp/B078WT2V85
CPU : XEON E3-1275

My environments are bellow,

- Disabled Fastboot
- CSM Enabled with "UEFI driver first"
- Disabled Secure Boot
- Disconnected other SATA cables

I booted windows and live cd of Fedora 28, but cannot see the PCI device(Fedora kernel include NVMe drivers).
What can I troubleshoot this?

Seems my problem is my USB sticks, I spent all weekend trying to get this darn MoBo flashed with the modified bios. Flashback works ok, it blinks as it should, then stops, I reboot but nothing happens when I get into bios. Tried another stick and it bricked my MoBo, had some nightmare hours fixing it. ((
Will borrow some other sticks from my work tomorrow, though it's beyond me what kind of USB it needs..

I reboot after the ROG connect LED stops blinking, is it correct? Or I should wait some time after that?
I'm confused a little bit really.

Do I have to flashback with the nvme m.2 SSD inserted or not? Or it does not matter?

On a Z87X-UD3H here guys, BIOS modded successfully and I could even flash it with Q-Flash. Exported BIOS image still shows that the NVMe driver is in place. I've bought a Corsair NX500 400GB to test with it and should have it sometime this weekend, looking forward to it!

@Alster
The USB flash drive should be USB2.0 8GB or smaller. From what I recall USB3.0 flash drives will not work. Also, when you flash the BIOS it shouldn't matter if you have the NVMe drive installed yet, but you might as well be prepared by disconnecting all other drives and have the NVMe drive installed. Upon booting to the flashed modded BIOS you should change all the settings that Fernando recommends and reboot. If the BIOS was modded correctly and the flash process was successful you should have something similar to "PATA SS" in the boot section of the BIOS.
