@skynet,
Cool. Glad you figured it out.

Here's my Benchmark for the 970 Evo NVMe drive running Window 7 via PCIe 4x on a Asus P8P67 Pro v3.0:

the ROM uploaded in my previous post works, so anyone is welcome to use it.

Big thanks again to @Fernando
Feel like i hit every road block possible to achieve this, but got there in the end

EDIT by Fernando: Since the inserted (too big sized) image didn't show up, I have attached just the benchmark results by using the Forum software.

Yes I think that is best. I still tried to get it to work and came extremely close. I used mbr2gpt to convert nvme. Then I rebuilt the bcd file. It showed in bios as boot drive. Then started to load windows but crashed with blue screen. Darn. I think it is possible and would have been useful information but in the end I did not make it work.

Gave up and did it normal way. I still think it would work, might need to mess about a bit more but it seems highly probable. I was hoping to figure out how so the next person would have an easier time and could just clone drive.

Fernando!...Hello!!!
Am back here after almost two years to finally upgrade my Asus P8Z68-V Pro / Gen3 from a Samsung 850 Pro SSD to an AngelBird Px1 PCIex4 adapter married with a 970 NVMe M.2 'stick'.

1st - Many Thanks for your comprehensive, Updated NVMe Guide including bios "self-modding" along with 'ready access' to the specific elements necessary to get the job done correctly!!!

2nd - Forgive me if this is already 'clearly' covered in the forum .....but can you confirm that for my MB cited above AND assuming I am using PCIex16_1 slot for a video card, I am left with two options for mounting the 970 Pro NVMe-AngelBird Adapter; A) The PCIex16_3 slot or B) The PCIex1_1 slot,,,,,with A) being a faster channel and preferable over B).

Appreciate Your Assistance & Any Comments

Happy Holidays!!!
Stan

Yes it worked. It means I just did a fresh install on Nvme. No drama. On my motherboard I did not need to do anything besides that after I modded the Bios.


I still think what I was trying to do would work. I used the built in tools to rebuild bcd, if instead I had deleted the boot folder entirely after mbr2gpt and then created a new one I think it would have worked, but I had already put enough time into my investigation.


Stan how are you planing to fit a pcie 4 card into a x1 or x3 slot? That seems unlikely to work.

I followed to updating bios but I'm having boot problem from ssd connected from pcie. so I did with flashback update and was successfully for R4G.CAP MOD. My Windows 10 sees my samsung 970 evo 1 tb ssd on desktop showing up in samsung magician app and everything is fine so I restored with rufus my usb flash with gpt windows 10 1809 version to bootable and I formatted 970 evo with windows 10,the problem is my motherboard can't see my ssd from pcie slot for this reason won't boot. Keep says csm issue press F1. I configure csm with uefi but no luck keep saying csm issue so any solution? and I'm trying with this topic for self modding bios NvmExpressDxe_4.ffs and NvmExpressDxe_Small.ffs but my motherboard refused usb flash when I get start to press button,usb and bios light flashes once and then goes out and stopped. But R4G.CAP with RAMPAGE GENE IV MOD CAP was succesfully update with the same usb. I'm really nervous and I'm trying to pass windows boot issue till 15 hours but no success. Can you help me please?

SpecS:
ASUS ROG Rampage IV GENE Motherboard
Intel Core i7 4820K 3.70 ghz
Samsung 970 EVO 1 TB SSD with Lycom DT-120 PCIe Adapter
ASUS RTX 2080 OC 8G
8X8 Gb HyperX FuryX 1600 mhz DDR3 Ram

Here is my modded bios on the attach file. @Fernando I'm just uploaded from to my motherboard bios again and was succesfully done. But nothing is changed.Still I can't see nothing in the boot section about SSD informations when I try to disable AHCI Controller.

1. Yes (I tried to upload with ASUS flashback mode and my usb started to uploading with flashing light and finished about 5 mins later. the usb and motherboard flashlight goes out after 5 mins. and done right?)
2. No I can't see anything in the boot section.

Thanks.

Fernando, am expecting an Angelbird Wings PX1 PCIe x4 M.2 Adapter card to mount in either an available PCIex or PCIex16 slot on my Asus P8Z68-V Pro/Gen3 MB. Am expecting the PCIex16_3 slot to run faster than either of the two PCIex slots.

Do you have a better idea than the adapter card cited?

Thanks

I thought I'd register to give my appreciation for this guide.

My old 512GB Kingston HyperX Predator M.2 SSD was getting cramped with the ever so increasing size of Games thus prompting me to buy a larger 1TB Samsung 970 PRO M.2 which refused to work with the stock 0701 BIOS of my finely aged ASUS Rampage IV Black Edition. An attempt in upgrading it to a Beta 0801 BIOS wouldn't solve the issue either slowly increasing my panic threshold until I came across various threads all linking to this post which solved my issue via the ROG Connect Flashback feature.

@Durahl Which Bios you did to use? and how did you put the 1TB Samsung 970 PRO M.2 in the motherboard? so as like me you connected with m.2 pcie adapter? please tell us more specifics about your situation. I can't flash modded bios via ROG Connect Flashback. I will change my usb flash. I used two usb (SanDisk and Toshiba usb) but no success! I have another usb Kingston 8 gb and I'm going to flash with this,I hope can success to upload bios at this time!
