Hey,

maybe we will get a function to include the NvmeExpressDxE (EFI NVMe Module) via UBU in the future? :)


EDIT:

Volume number (CSMCORE) will be hard to identify...isn't it? :(

Yes, for this reason.

According to the 950 Pro manual "Booting is accomplished through a feature called the Compatibility Support Module (CSM) that emulates a BIOS environment in the UEFI mode. The Samsung 950 PRO Option ROM resides inside the SSD, enabling the SSD to be the primary boot device and supports the UEFI."

So apparently any "UEFI Only" settings in CSM do not apply to the 950 Pro. With CSM enabled it always boots in legacy mode through its internal Option ROM.

It will use UEFI mode with CSM disabled. With CSM enabled it initialises in legacy mode but still allows booting the OS in UEFI mode.

Ahhhh, thanks for clarifications :)

I just poked at X79 Deluxe bios... very recent this month, it contains 3x nvme related files, I wonder what are these.

The 950 Pro manual mentions that in CSM mode, the Option ROM loads an NVMe driver for UEFI boot. This looks more or less like what we're doing by modding the BIOS for CSM Disabled. It isn't actually a legacy boot.

Greetings everyone. I have a problem with my S2600CP (Intel) board. I am trying to get a 950 PRO to work with the board but it simply won't POST. Found this guide to include the NVMe driver but I'm being met with a Security Check error of the modified BIOS file. I've seen steps to bypass ASROCK/GIGABYTE/ASUS boards but I can't find any for Intel. I don't want to boot from the 950 PRO, I just want to use it as a cache device. Chipset is C602 and Processor is a xeon e5-2620v1.

Any suggestions?

Hi Dieter,

Thanks for your quick answer! What do you mean with "But with other BIOS settings within the "BOOT" section of the original BIOS"? Are we talking about editing something in the file itself with the AMI Tool?

There was a guy at another forum who sent me this video: https://youtu.be/vAEhHfsNj58?t=4m55s <- Apparently they had to do some bios modding as well, however I'm not entirely sure what they did.

The 950 Pro should boot in legacy mode. Disable any UEFI only boot settings.
