NVME BIOS modding

techdiode · May 31, 2017

NVME support can be added with a BIOS mod on intel chipsets prior to the 9 series.

I've been trying to follow this tutorial: http://www.win-raid.com/t871f16-Guide-How-to-get-full-NVMe-support-for-all-Systems-with-an-AMI-UEFI-BIOS.html

I've been able to add the NVME package to the BIOS file. Problem is I'm trying to do it to an ASUS B85M-G R2.0 . When I export the .CAP file and try to flash it I get a security verification failed message. This tutorial is rather vague on how to get around this for ASUS boards. I followed the process it mentioned for Asrock boards, but it still gives the security message.

Anyone know how to bypass the security check? I guess older boards like in X58 didn't have the security check and are really easy to add NVME support.

In case you are curious I'm just using a PCIe adapter with a Samsung 951 drive. I can install an OS to it without problem, it just doesn't get detected in the BIOS to boot unless I can get this BIOS mod applied. Also, to note, it is interesting that Asrock has a BIOS update for their B85 boards for NVME support, Asus just doesn't seem to care as much.

1) X58 boards doesn't have UEFI, ie. they CAN'T be moded this way.
For any non-UEFI system, you need to use Clover program to take care of booting from GPT drive : LINK.
2) You never boot from NVM'e drive itself.
After initial Windows installation, you will have a option to boot from Windows Boot Manager.
You choose that to boot into Windows.
It requires EFI mode active on booting devices, and will not be available in Legacy only mode.
3) I you didn't have any space to put dxe module in, you have to rebuild and recompress the whole file. This info is on the last page of the win-raid guide thread you linked.
4) Try this method : LINK

Interesting that the security can be overridden by flashing an official bios and then flashing another without reboot. Seems like that makes the security feature not a security feature. lol

I would like to know if you were successful hehe I have the same Motherboard and I already added the dxe module and I don't know if you still have the same motherboard since I think this thread is very old but I'm trying to update it but i don't get pass the verification
