@Fernando Thanks for the follow-up yet again! Just out of curiosity, do you have a sense of what all is rolled into the NvmExpressDxe_4 module? For example, I've seen another tutorial looking to accomplish these same results, which suggests taking those 3 modules shown in my prior pic from a Z97 board with NVMe support and inserting them into, for example, a Z68 board (which I also have). From a technical standpoint, I'm just left wondering how the single module accomplishes what the three separate ones do. e.g., does it somehow roll all of the feature into one?

Hi again, & excuse me for stole your time. I've found a Ssd with astonishing specs..., it sems, at least. I know that through a PCIe adapter i wont obtain best features but... The ssd is Xpg Spectrix S40g 512gb M.2 2280, the web of Adata offers full support for many systems, talking about NVMe drivers & other topics. My doubt is related to the NVMe gen 1.3; does this any difference about my modifyed Asus M5A97 PRO bios?

Thx a lot for your time.

@Fernando:
Success!
The BIOS file modded perfectly as per your guide. But you were right that the inbuilt EZ Flash utility put up a security warning and wouldn't let me flash.
So I used the Asus AI Suite flash utility as per your link. I'm not very good with CMD prompt stuff so went that way! All worked fine with PATA SS appearing.
I left CMS on with everything set to UEFI but deleted the keys to switch off secure boot. Windows 10 then installed fine and let me choose it in boot priority.
Now it's just remembering how much tweaking and re-installing I need to do to the OS from clean install. Ugh!

Thanks very much for your help and guide. I'll throw you some PayPal from your donate link.

Thx a lot!

@Fernando I tried deleting the stock NVMe modules in the f16j beta BIOS for the Z77X-UD5H board and inserting NvmExpressDxe_4. It flashed without issue. The primary distinction I'm seeing so far is the fact that the entry for the NVMe drive is now showing what appears to be the drive's serial number (or firmware?), which I didn't see before with the stock NVMe modules, just the size, brand, and model of NVMe drive. I would guess that is promising, given the fact that more information about the drive is being reflected in the BIOS. Will keep you posted.

Very happy camper! Cheers again.

Hi,

I modified the bios and installed the system. System has installed correctly but I have a diffrent problem. When I turn off PC or restart,
the computer turns on and off several times before it starts properly and the system login window appears. Someone knows what could be the reason?
Currently I have a second disk attached but when I unplug it the same happens.

I am sending my bios configuration, maybe there is something wrongly ?

Hi @NickBOT , excuse me, you're obtaining these rates through a PCIexpress 0.2 x16 port?

No it's gen 3.0 PCIe x16 on a Z87-A mobo.

Though it also shares the lanes with my GPU which is in the first x16 slot.

Thx 4 your time!

Hi,
