U need "native driver support in NVM Express in Windows 7", also if there is a driver from ur NVme SSD manufacturer, u should install it. Keep in mind that u do not need the bios mod just for using the NVme drive as storage as long as OS supports it and correct drivers installed.

Yes, i know i can use NVMe drives for storage with no many truobles to solve. Thx @MeatWar.

Look, i'm just making a try, i've found 2 little problems... Can't find anywhere AMI's MMTool 4.50.0023, or another version for download, so i'm using the free UEFITool. Once the rom is opened a comment is displayed & the modules are expanded no "bios region" is displayed. I assume that's just a difference beetween Intel & AMD's formats. A comment is displayed down there...
I've found that the 2° tree contains all the DXE stuff, but i don't find there any PCIeLaneDXE


Well, it's done..., & everything looks right, except for this "parseBios: one of volumes inside overlaps the end of data" comment down there..., is the same message appeared in the original .rom.
Another detail; both files, original & moded bios has the same size, i've inserted the "NvmExpressDxe_4.ffs", not the small...;

For sure i've missed soma of the lines in the guide, i'ii read it again carefully.
I've insered after de mod file, not the small, in the place you've pointed in the guide, i think it's allright, i guess...
Before flash my mobo i'll tray to get my system into GPT mode, in another disk, just to see it "clonable" for the future NVMe drive, & to achieve the chance of an UEFI clasical boot
Your guide & help is very important for me, thx a lot.

@Fernando & @MeatWar
Look, this is my modifyed .rom:


EDIT by Fernando: 2 posts merged and picture resized (to save space, can be enlarged by clicking onto it)

Ok!, can i attach both roms here?

Thx a lot for your valuable time, thx for @MeatWar & the whole crew too.

I'll be back with some of my music as a humble gift for your help when my NVMe let me record some.

@Fernando SUCCESFULL FLASH!

I've not seen anything strange or new about typical new mobos UEFI, as secure boot, fast boot or some like that, i assume is related to the absence of an UEFI/GPT system attached to any sata port. I've gotta finish a guitar & a computer for a couple of clients, inmediately after i'll start tests installing Win 10 in order to see if legendary "Windows Boot Manager" appears & some other stuff... I'll make a GPT version of my 7 Ultimate too (from live cmd recovery/repair mode). I'll keep all of you updated, specially about the progress of my 7 Ultimate onto a NVMe unit, i hope a nice & fast Frankenstein born!

I wanna buy a Corsair Mp510, that company does not offer any Win 7 NVMe driver yet..., i hope the KB2908783-x64, KB2990941-x64 & KB3087873-v2-x64 patches helps a little in the process, later could open a thread talking about the whole experience, if admins aprove it.

THX!!!

Hello Everyone,

I am trying to modify the bios. I have ASRock X79 Fatality Champion mainboard. I modified BIOS by UEFITool but when I save modified bios file, the file save in .ROM format but the original BIOS file from ASRock page has format .80
My mainboard does not have USB flashback so I have to flash it from BIOS. Is there any solution to this problem ?

2. I have use "NvmExpressDxe_4" module, is there any newer more efficient version ?

Thanks :)

@Fernando you might be just the bull to help me out. I'm trying to get a 2TB Samsung 970 EVO Plus up and running on my Z77X-UD5H board with the most recent F16j BIOS. As others might have noted, this BIOS does have 3 NVMe modules built into it (see pic/link), though I'm hoping to integrate the most current NVMe module as I've been seeing some minor issues with using a Windows 10 installer to properly recognize the drive as well as with Mac OS. e.g., trying to install Clover to the EFI partition is a no-go. Perhaps I missed it on your guide, but if the BIOS already has these NVMe modules in it, is the NvmExpressDxe_4 module additive to what is already in the BIOS (e.g, 4 modules total), or, should I remove the ones in there and simply insert NvmExpressDxe_4? The post-insertion screenshot appears to show the sole NvmExpressDxe_4 module, without any others indicated, which would seem to suggest that the older modules are no longer needed. Could you clarify?

TIA!
MMTool 4.5 f16J BIOS

@Fernando

More to come on the Windows specifics. Perhaps the primary consideration I would offer as it regards the NVMe implementation being in need of updating is due to the fact that the BIOS is considered a beta. The board didn't initially ship with the support and NVMe support isn't even indicated as one of the improvements to the BIOS release (or any of the releases for that matter).

Doesn't the prospect of a single module, NvmExpressDxe_4, being applicable and beneficial/functional for even the 6 series boards (which we know did not have the support factored into the design), suggest that it would be viable? For example, while I haven't investigated all of the BIOS releases, I have read that the NVMe modules were introduced in version F14 for the UD5H board. Basically, what is the difference between stripping the NVMe modules in the beta BIOS while integrating the singular NvmExpressDxe_4 as compared to adding that same module to say, the F13 BIOS without any NVMe support baked in? Does that make sense?
