@nikfro Updated above file for CPU microcode only

EFI ROM updates:


Microcode update: v28

I need the previous version that you uploaded, the latest version of the BIOS does not work for me, can you throw off the file that you uploaded a couple of months ago ?

@nikfro See post #30

Try setting CSM (Compatibility Support Mode) = DISABLED so you can natively boot from the M.2 drive.
Also ensure that the drive partition is not MBR (Master Boot Record); but rather formatted as GPT (Gui Partition Table).

So in sum, drive must be GPT formatted and CSM = DISABLED are pre-conditions to the OS natively booting from the NVMe M.2 drive.

When you are doing the first install, ensure all other drives ie your CD-RW, and other SATA hard drives, etc are not installed. ( You can hook them up later)

The good news is your UEFI drive is showing up as a boot selectable device, which of course is the desired drive to select.

Have you tried installing via a smaller USB drive eg. 8GB, 16GB stick (FAT32 format); I believe you have a 250GB stick there?

Also are you using the latest x64bit version of Manjaro v19.0.2 which will run on the modern hardware. (Note the 32 bit will only run on the older hardware)

I've used Debian v9 and v10 on my Asus Z87 Deluxe with good success and has the same chipset as your MSI board.

I'm guessing here, but perhaps Manjaro Budgie 18.0.4 doesn't have the full support for UEFI; and Manjaro 19.0.2 (x64bit version) may well get you where to want to go...

One other thought is to Enable the Windows 8/8.1 setting, as sometimes different manufacturers implement feature sets differently.

Anyway, I would give that a whirl, as it appears your 98% of the way to sucesss. What have you got to lose?

It looks like you're just a tinker or two from full NVMe booting. :)

Windows8/8.1 may needs to be enabled here as Hancor mentioned.
On Security Page, or within windows8 config (reboot after enable, back to here, if after enable Win8 the "secure Boot" submenu doesn't appear), inside secure boot submenu enable "Secure Boot Support" (NOT Mode) otherwise CSM will always remain enabled, since it's hidden from you on hidden boot menu
If you still never see "Secure Boot" submenu at the win8 config page (Your first image above) then let me know, I will make you mod BIOS using Hacor's BIOS as base and reveal this submenu for you

Excellent! Delighted to hear you have got yourself out of the woods and to NVMe booting SUCCESS.

I flashed this BIOS yesterday and installed a NVME M.2 SSD via a PCIE adapter. Here is the weird thing happening on my board, the PCIE adapter (of course together with the SSD) is only recognizable in BIOS after a cold reboot. Any soft reboot (Reset button or Ctrl-Alt-Del) will cause the adapter and SSD missing in BIOS, in the "Board Explorer", the PCIE adapter does not exist at all. After a cold reboot, it will appear again.

I switched between PCIE5 and PCIE7 but the issue happens on both plugs. Please refer to the picture below, the adapter is on the very left PCIE plug

Hi, Newbie here. I think I managed to update my bios using this modded BIOS on my MSI Z87 G45 motherboard. It's still functioning and when I copy over the current bios it appears to have the NvmExpressDxe_4 driver installed when I load it up using the MMTool. I bought a Samsung Evo Plus along with the Asus Hyper Nvme adapter but it does not show up anywhere and no new PATA disk drive has appeared since the update. I was wondering if I'm missing something here? Any help would be much appreciated as I'd love to be able to use my brand new 2TB drive.

Follow up: It was not a bios problem. I shouldn't have installed the SSD in the second slot of the nvme adapter. It's now sitting in slot 1, I just formatted the drive and it's working. Thank you very for creating this and saving me several hundred bucks from having to go buy a new motherboard.

@baaden

Yes some NVMe/SATA adapters have specific slots for specific interface functionality.
Always read the fine print in the adapter manual!
Deligthed you are out of the woods, and into the NVMe wonderland...

I took the hancor BIOS file as a basis for the mod and update him. This bios file have last update Network OROM Intel Boot Agent GE 1.5.62 and EFI Lx Killer Undi 1.1.0.10

NVME driver available too

I tested this bios on my MB with i7-4790k, good work.
