Hi,

First of all: This is my first thread, if it is in any way deemed to be inappropriate, please tell me.

Long story short: I have an Samsung Spin 9 (NP940X4L-K01US), updated BIOS to latest P09AFD, and tried to get a 950Pro 512gb to work.
Slot fits, after intel documentation it should only be a matter of "flexible" IO to assign the SATA-Ports to PCIE storage.

The original BIOS is a joke, so I went for IFR extraction and played with "setup_var" till the point where I bricked my laptop.
Then came this forum to the rescue (thanks to @CodeRush for his very good thread on this matter), and I purchased a CH341a and reflashed my BIOS.

Furthermore I managed to activate all the advanced settings.
BUT: Whatever settings I try, the NVME is not showing up. Neither in BIOS, nor in my efi shell (thought it might appear as a mere pci device).
I tried nearly all combinations of SATA-Controller enable/disable/AHCI/RAID, Intel RST PCIE storage remapping enable/disable, port auto/5/6/7/8 (should be 8 on Skylake PCH according to Intel).

Nothing.

Maybe anyone is familiar and I'm missing something? I'm a quick study, but maybe I still overlooked something.


When ever I try to update the Intel RST OROM via UBU, the menu "Intel Rapid Storage Technology" disappears in BIOS when I put the controller in RAID mode.
With the original BIOS this entry is hidden, unless "RAID" is selected, but then again "no disks connected"....
There are even options for NVME-drives in the BIOS, AMI EFI NVME driver is also present.


Thanks for this forum, at least it helped me to unbrick my laptop several times :-)

Just how or what method did you employ to activate Nvme??

Hi,

Thank you for the welcome.
To Answer your questions:

1. No OS currently (because of fore mentioned problems)
2. I cannot say, there is no way to start an OS, but UEFI is enabled, CSM is disabled, Secure boot is also disabled
3. Yes there is, UBU says its an AMI EFI NVME, there is even a module called NvmeRecovery, so the BIOS should be definitely capable.
4. I'm about to try with Windows 10, I also reflashed the "original" bios, just containing the menu mod. So far no luck.

Greetings

Oh so your having a configuration issue. You should have native support. First of all how is the drive connected onto the motherboard? Does turning off RST pcie mapping make the drive visible?

This is what I recommend to try:
1. Create a bootable FAT32 formatted USB Flash Drive with the desired Win10 image by using the tool Rufus. Make sure, that the GUIMode Partition Table has been enabled within the Rufus GUI.
2. Unplug all devices except the NVMe SSD.
3. Boot off the USB Flash Drive in UEFI mode and check, whether your NVMe SSD will be detected by the Win10 Setup.

Hi, even though it sounds like a plan, I already had my encounters with Samsung "Technical" Support, and helpful answers like "Please install the latest drivers".
Not so helpful.

I'm now going for a WinPE, and try to fiddle the PCI registers with H/W RW Everything. Maybe something comes up.....

If anything changes, I'll keep you posted.

So long...

Hi All,


I found a promising lead. Looks like the feature I'm seeking is called "SATA Express" which allows switching of M.2 connection between SATA and PCIE mode.
While reading the INTEL PCH specification, I found this:

Use FITC to set the soft straps of the SATA/PCIe* Combo Port 1 Strap (PCIE_SATA_P1_FLEX) that select this port as SATA Port 1 or PCIe* Port 8. The default SATA/PCIe* port assignment is PCIe* Port 8.

---

In my Bios I have an option for each port, called "Typology" with an option called "Flex"... Never set it to this value, according to Intel this should let the controller probe for and enable PCIE instead of SATA.....
Keep you posted....
