Hello!
I have an ASUS N73SV laptop & SSD 2.5 with SATAIII interfece.
Laptop can not boot from this SSD
I modified the bios and added the NVMe module!
According to the instructions. But, it does not help. Loading SSD does not work! Tell me if someone else knows what modules are missing in Bios.
Thanks!

Hello dear friends can you tell me if I modify the BIOS of the motherboard P8Z68-VPRO/GEN3 can I use Samsung 970 PRO [MZ-V7P512BW]? did anyone here have any experience with this motherboard?

@a4tech111:
Unfortunately I have no experience with either the referenced motherboard or the NVMe SSD model, but according the specifications it should work.

If you are using an Ivy Bridge CPU then you will have PCIe 3.0 support in the two blue/white PCIe x16/x8 slots. Note when using a Sandy Bridge CPU, you will have PCIe 2.0 only and there is no significant difference between CPU and chipset PCIe lanes.
All the other PCIe slots (including the black one) are served by the Z68 chipset that supports PCIe 2.0 only, even with an Ivy Bridge CPU.

Note that PCIe 2.0 x1 is slightly slower than SATA III 6Gb/s, you will need to install it to slot that is providing at least PCIe x4 lanes to experience the NVMe performance. Also note that the black PCIe slot is sharing lanes with a lot of other things (see the manual) so you need to disable (or not use) all of those things if you want to use that slot.

As a side note, you will be able to use an NVMe SSD without any BIOS modifications, but you will need the BIOS modification if you want to boot from the NVMe SSD.

Hello.

Thanks to this guide I'm able to use AXAGON PCEM2-S adapter with Samsung 970 EVO (500GB) on my ASUS Z77-A motherboard.

Thank you for this awesome guide!

What does this mean? What exactly have you done and what happened?

variant 1

variant 2

bios

@suz191 looks like your BIOS has native NVME support already, according to your second image, no need to modify

@Lost_N_BIOS No, no support! After inserting NvmExpressDxe_4 failed. I tried another variant. I took (Nvme, NvmeSmm, NVMEINT13) from bios Z97 and put it in there. But that didn't work either! I think I need to change the modules that interfere with work! But, I don't know which ones!

OK, now I see what you did, thanks for explaining! I thought second image was stock BIOS, with already NVME in there. What do you meant when you said "In both variant of these options, I get the same thing as described in paragraph (2)"?

In your BIOS, Advanced >> Sata Configuration, what is in there? Please link me to your stock BIOS, I will look around, and if necessary enable hidden settings for you if you if necessary (Secure boot, fast boot, CSM and OS type choice, etc). You may need to do method below, with UEFI Disable and CSM way.
But, keep in mind, I only mod BIOS, I have never used NVME, so only know about putting in BIOS and from what I've read people discussing.

I have never seen anyone, ever mention having to remove other modules for NVME, except for space requirements, to make room to insert module ect, never in order for functionality so I highly doubt you need to remove anything.

You may need to use these methods mentioned on page one
Alternative methods to use an NVMe SSD as bootable drive with older systems (no BIOS modding required):
1."Clover-EFI Bootloader Method", developed by our Forum member Nyctophilia (look >here<)
2."DUET-USB Boot Method" developed by our Forum member mireque (look >here< and >here<)

Then, as I mentioned you probably have to use one of the alternative methods for booting, linked on page one (For older systems)
[Guide] NVMe-boot without modding your UEFI/BIOS (Clover-EFI bootloader method)
[Guide] NVMe-boot for systems with legacy BIOS and older-UEFI (DUET-REFIND)

I'll look into your BIOS and see if important settings are hidden for you (I assume so!) But, you still may have to use one of the above methods.
Please upload file to another host, I always get that site blocked due to malicious warnings from both spyware/adware program and anti-virus.

@Fernando, second link in "Alternative methods for older systems" @ DUET-USB needs fixed?

The SATA ports do not support the NVMe protocol.
