May be I will ask you the question of lol? but I cannot find how to solve. My mb GA-z170 gaming k3,bios F2C. If I use UEFITool and open bios, I see below this: parseFile: non-empty pad-file contents will be destroyed after volume modifications. If I use MMTool Aptio, there is not the CSMCORE module in the list. Impasse. Sorry for my english

The need to modify the BIOS under nvme due to the fact that my
the motherboard does not see the nvme drive, even as a normal non-boot diskdrive. All the advices comes down to the fact that I have to update the BIOS. May be, that in the first BIOS versions nvme support was closed, I don't know exactly. But for overclocking the CPU skylake(non-k) over bus-there is no new BIOS, because of the ban intel
F2C BIOS is the only BIOS for overclocking skylake processors over bus on my motherboard. It is clear why Gigabyte removed it from the site.
Is there a way to modify my BIOS according to your instruction for nvme support?
p.s. I'm so sorry, could you see if my BIOS has nvme support if I send it to you

If your ever looking for a BIOS for Gigabyte that's been pulled from the main site, use Gigabyte's BIOS repo (in MOST case's, there are some that have gone POOF from here as well!):

Thanks for the link, but I'm not looking for this BIOS, I have it installed and running on my motherboard. Another BIOS for overclocking over bus on my motherboard simply does not exist
I have a problem that it does not support nvme disks though should support

Thanks for your help. That the nvme module is in BIOS I understood, it is good. But the fact that the support strongly advises to update the BIOS leads me to think that it is either blocked or not working correctly on the first BIOS variants. Let me explain why I think so. In the presence of some function in the BIOS, there is always a point that turns it on or off. For example: on my board there is a connector M2. I well studied all functions of the BIOS, but there is no point of type of switching from sata-to m2-pci-e. How will the PCI-e M2 controller turn on if it shares lines with sata? In this BIOS there is no option besides AHCI and RAID. After all, by default everything is in the AHCI, so in sata. By the way, in the BIOSes of other vendors (ASUS, ASRock), the switch is in the BIOS.

Sorry, I'm not an expert in BIOS and even more GUID, I'm a regular user. Logically, if something does not work - I'm looking for where to include. The M2 of my Board works with both sata and pci-e. Here is what is written in the specification: connector M. 2 (Socket 3, M key, Type 2242/2260/2280/22110 the ability to connect SATA and PCIe x4/x2/x1 SSD-drives). At the same time, SATA and pci-e have common lines. By default, they see sata. If the sata slots are empty, and drive pci-e is installed in the M2 and the BIOS does not see it, it means that it does not automatically switch to M2 in pci-e. Logical? But in my version of BIOS there is no point switching

Of course, to initialize the disk, I first started the system with default settings without other drives.
There is a possibility of incompatibility between the disk and the motherboard. I'll check the drive on another computer tomorrow. If the disk is healthy, I will update BIOS. If, after updating the BIOS the drive will work, so it's in the BIOS. The disk will have to be changed to a regular SATA, because overclocking is more important than disk support. Thank you for your help and I wish you success

I meant success in the development of projects to help people like me

Fernando, hello!
Could you please help me?
I've got MSI B85-G43 motherboard and i recently bought Samsung 970 evo pce-e drive with an adapter. So after that i found out that it's not compatible with default bios.
I was able to successfully mod bios with MMTool and flash it onto the mobo. I checked with UEFItool that the Nvme driver appeared undermost of the modules list and that the Pad file was not removed.
Flashing went fine and bios started to recognize the drive (shows Samsung controller now and not an unknown device in the pci slot). Next i was able to make a bootable flash drive with Windows 10 and to install it on the ssd, but...
Bios doesn't show the drive in bootable devices, Windows Boot Manager did not appear in the boot menu.
I don't know what to do, i followed every step of your instruction.
Even with no other drives connected to mobo it doesn't show the ssd.
Please, tell me what can i do to fix it?
