But I see it with my own eyes. Moreover, I have 2 servers with the same motherboards, I experimented only on one, the second was with the original BIOS. I just tried to install the OS on the SSD in exactly the same way and the SSD was not in the list for launching. After flashing the modified BIOS, the SSD appeared
I reset the CMS setting to its original value (enabled), on the other server I didn’t touch it at all
@LazyMechanic
No mainboard needs 2 (different) NVMe modules within the BIOS to be able to get Win10/11 installed onto an NVMe SSD.
Maybe you have forgotten to set it to “Disabled”.
This may be true, I have not tried to install windows after the first attempt on a modified bios with disabled CMS. Anyway, the modified bios works with TrueNAS and I’m happy
@LazyMechanic
I repeat: The insertion of a second NVMe module into a BIOS was not a good idea.
It may even cause long-term NVMe problems (loading of 2 different NVMe modules while booting).
Okay, I restore original bios, there is no boot disk: pic 1,2
Modified bios, there is boot disk: pic 3
CSM enabled on both bios: pic 4
This is not a proof, that the originally present NVMe BIOS module doesn’t work correctly. I am pretty sure, that the natively present module will allow you the booting off your NVMe SSD.
Note:
After each BIOS flashing procedure it is very important to enter the BIOS, to recover all required or desired specific BIOS settings, to save the altered settings and to restart the PC.
Did you do all that?
I did it many times, but before I went looking for a way to add the ability to boot from nvme (this forum). I restored the settings, changed different versions of the BIOS, changed different parameters (which I already wrote about), but nothing worked. I may say something stupid, but could it be that this driver in the original BIOS is responsible for supporting nvme in general, so that it can be interacted with, and not for booting?
No. The NVMe EFI BIOS module is only required and used by the machine while booting off an NVMe SSD. PCs/notebooks without NVMe EFI module within the BIOS can use an NVMe SSD for storage purposes, but will never be able to boot off it and to use it as complete system drive (with the boot sector on it).
Hello everyone, I wanted to know if this guide is also good for Asus H81M-K, I purchased this kit: SABRENT PCIe SSD M.2 NVME Adapter, PCIe X16/X8/X4 Card with Aluminum Heatsink, Adapter for SSD 1TB, 2TB, 4TB, 8TB up to 16TB, 2230/2242/2260/2280 format (EC-PCIE) and at home I already had the Silicon Power 1TB US75 NVMe 4.0 Gen4 PCIe M.2 SSD R/W up to 7,000/6,500 MB/s (SP01KGBP44US7505), I wanted to know if it could work, my goal was to launch the operating system from the nvme ssd. PS: Thank you in advance for any answers and help and I wish you all a Happy New Year.
It should work as intended, regarding the UEFI NVMe boot capability.
This is general rule for the NVMe mod for old boards, of course we cant confirm all kind of PCIe adapters and disks compatibility, across all hardware brands/models available on the market.
Keep in mind that any Gen 4.0 NVMe disk will negotiate @ PCIe 3.0/2.0 X4, due to the generation of the Intel H81 chipset (cheap mboards…), most H81 boards will be down to PCIe 2.0 x16/8/4 and not 3.0 as can you see in a Z87 boards.
I want to thank everyone who participated in this thread including Fernando, I read and followed the guide at the same time I registered, everything works, the installation started on ssd nvme silicon Power US75 NVMe 4.0 Gen4 PCIe M.2 SSD R/W up to 7,000/6,500 MB/s (SP01KGBP44US7505) it was hard to read the entire thread and I also ran into the exact same problems as other users but by reading Fernando’s guide carefully and following it to the letter I succeeded, thank you very much to everyone.
@Koda
Thanks for your feedback and your donation.
Enjoy the speed of an NVMe SSD while using it as bootable system drive!
Hi Fernando my name is Alex, my donation is a sign of respect for the work and support you continue to give to all the users of this thread, as a former moderator and former releasee I am aware that a thank you can be satisfying and even more so a small donation and I know that it is not easy to bring such content to those who do not chew a bit of computer science and many times some users demand a ready-made solution.
PS: Every problem has three solutions: my solution, your solution and the right solution.

@NafRaid
What was your intention while writing this post, which has nothing to do with the topic of this thread?
It is not even clear which question/problem you have and which sort of support you expect.
