That must not have gotten posted then, this BB is kind of strange to me still.
Anyway, I immediately inserted the M.2 adapter with the M.2 connected and tried every boot option that I could enable or disable, OpROM, CSM, SATA/IDE/RAID/AHCI... Everywhere just empty. I checked when I only had a keyboard and HDMI for the the built in GPU connected.

@ZaInT:
Questions:
1. How did you flash the modded BIOS?
2. Are you sure, that the modded BIOS has been successfully flashed?
3. Is the NVMe SSD connected to a matching PCIe slot?
4. Can you see the attached SSD within the Device Manager and Disk Management of your currently running Windows OS?

Thanks, Dieter!
Checked your firmware. Unfortunately, it has not happened yet.
When using the ASUS EZ Flash 2 utility, the following message appears: Security verification failed.
When using FPT: Error 280: Failed to disable write protection for the BIOS space!
On the link you sent: the information is interesting, but on my Board I did not find the BIOS FlashBack Button.
With Respect Valentin.

@Fernando
How do I confirm that my PC is using the modded BIOS? I figured reverting to the older 1505 version and then flashing the new modded 1603 version would do it.
I entered BIOS with all SATA ports cleared. Fast Boot was already disabled and then I disabled Secure Boot as well. The problem is, BIOS is still not detecting anything from the PCIe slot that my NVMe is in.
In the attached picture showing my PCIe config, PCIEX16_1 is my 1080ti GPU, PCIEX16_2 is where my NVMe is plugged in and it shows "Not Present".

I am not trying to boot off the NVMe since my OS is already on the 840 EVO and I am just trying to use it for game storage. Maybe I should consider returning the 970 EVO and buying an 860 SATA drive to avoid the complications?

Thanks again for your help.

If PATA or PATA SS is not in the "BIOS Features", "Boot Option Priorities" section of your BIOS, either the modded BIOS was not flashed successfully or the SSD or adapter is faulty. Can you boot to Windows with an SATA drive and the M.2 installed to see if Windows detects it in Device Manager and/or Disk Management? If the drive is visible in Windows, I would say the BIOS flash was unsuccessful. If the drive does not show up in Windows, I would suspect the PCIe-M.2 adapter or the M.2 SSD.

Did you try the link that Fernando gave you? I am not familiar with flashing Asus motherboards, but the guide he directed you to has information that may be helpful to you.

@abbajuu

check your PCIe adapter with M.2 SSD. Try another slot or remove your graphics card too /use onboard graphics for testing the adapter instead/ - you can use all 3 slots to see if the adapter is recognized by BIOS. Don't look for any NVMe signs but the multiplier of the bus speed should be there /x2, x4/ if the adapter is ok. Try to play with the slot setting where the adapter is plugged in - AUTO, GEN1, GEN2 or GEN3.

An empty adapter /without NVMe SSD/ is not recognized by BIOS as an device in PCIe slot

Here is my BIOS --> PCIEX16_1 x4 is my PCIe to M.2 adapter, PCIE16_2 x8 is my Radeon card

I found a very interesting thing that i got a efi bios of asus p5q-deluxe(775),and i followed the tutorial you post and flashed it!!!
After i installed the nvme ssd(samsung PM961), I could only see the pata ss,but not windows boot manager(other motherboards installed with this nvme ssd could show the windows boot manager)!!!so i could launch the system with the nvme ssd.

here is the original bios without modded,could anyone can help me to mod this?

@gloobox - 775 motherboard cannot use this method, nor boot to NVME, it's too old of chipset and BIOS type. This is for AMI UEFI BIOS only, around Z68 chipset onwards in most instances (Maybe some P67/H67)

Yes @Fernando sorry, I did not download the BIOS, since 775 has zero UEFI BIOS I assumed this would not be possible. I was not aware non-UEFI BIOS could boot or use NVME, but certainly knew this method for insertion into UEFI shouldn't apply to a socket 775 board.
Is this a new thing, and he's first to test, or have you seen someone try before? If you have seen before, any success stories?
