Wow... I did not know that it is possible to modify the BIOS.
It's pretty dangerous .... basically I just need the 1st item from UBO, but anyway there are many questions ... for example, what will happen to my current RAID0 - will it be destroyed or not?
Even if everything works out, how much will the performance of the drives grow ... 3-5%?

I have a samsung 950 pro nvme drive and Intel mainboard DX58SO. I cannot seem to make this work.

I was able to install windows and boot, but then after some windows updates took place, and I rebooted, then windows would not boot. It said my boot device is not valid. I could not even access that 950 as a storage drive in another windows installed on a samsung 840 ssd.

I had to remove the 950, take it to my friends new computer with a new mobo to even have it formatted.

Then I retried, and the same thing happened again.

Could you possibly help me to make this a functional setup?

You need to isolate which Windows update is causing the problem and block it.

Thanks! I figured that might have to be my next step. Might someone be so nice to give some advice or pointers as to how to achieve this?

EDIT: I am not sure, but I think some Intel RST stuff might be the problem, but:

a) I am not sure, and
b) I do not know how to identify the right update, let alone how to block it, and
c) What if another update comes after some time, again wrecking my system?

Thanks!

1) I am running windows 10 x64.
2) I don't think my x58 motherboard (DX58SO) supports booting off an NVMe SSD, EXCEPT for my Samsung 950 PRO. I have tried other NVMe SSDs, but with them I was not able to ever boot. With Samsung 950 PRO, I was have been able to boot without any tweaking. Like just installing Windows from the usb prepared via Rufus, and then booting to Windows. The second time I installed Windows this way, I was not able to boot even once, though. But I think that was because I had my ethernet cable connected, and I think I had had Windows install some updates already during the installation phase.
3) I am not sure. I think the first time I had the BIOS option "UEFI Boot" on, and the second time maybe off. Both times I had windows installation boot from the USB stick, and successfully started to install Windows on 950 PRO.
4) I think my 950 PRO used the integrated Option ROM NVMe controller. At least I did not try any tweaks, so I don't know what other controller it could have used.

Hello,

I have bought a new motherboard for my file server (Asus P10S-M WS with C236 chipset). I use Raid1 configuration and I would like to have a spin-down timeout but when I try to install new driver with Intel RSTe, HDD don't spin-down anyway.

So I have 2 questions :
- Which is the best driver which can spin-down my hdd after idle timeout ?
- Do you know what is the SATA DTIO config in Bios ?

Thank you in advance for your answer.
