You can order an ch341a programmer stick on ebay, put your bios into it and "upload" your new bios directly to the chip. So you got no problems with protection.
If your gonna order an programmer stick, just order a bios chip as well, so you can use your own bios chip as an backup. Thats what I did.
I didn't found any other way, to get a own bios mod to this chip.

@JackSted
I'm using the UEFI Bios mod. I didn't tried the windows startup repair so far. I will give it a try tonight.
Is it possible, that the nvme mod on the bios just works with CPU0, so just with pci lane 1 to 3/4 ?
Isn't it possible to get bifurcation for these lanes?

If you used UEFI BIOS mod, can you still set Windows Boot Manager as startup in UEFI BIOS.

I can't see any boot manager, when my hyper card is in pci lane 5 to 7.

So maybe the best and easiest solution would be, to have one m2 card in slot #1 as boot device and the hypercard with all other m2 cards in slot 5 to 7 with bifurcation?

Since PCIe slot 1 and 3 are shared x16, bifurcation on your motherboard bifurcation probably won't work there, you will need to use slot 5 or 7. You could try the DUET or Clover boot methods to see if those work. It is possible your current or all boot method's can't find the NVME drives on the other CPU. Alternatively if all else fails you could buy a decent 250GB SATA SSD just for windows, you will not notice a speed difference if your software, project data and swap file are all on NVME as I mentioned before, especialy if all 3 are on different NVME drives.

@paranoid_android - without USB Flashback best and safest method is via FPT BIOS region flash (Highly suggested over anything AFU) - otherwise get flash programmer as mentioned then you can do whatever you want (ie unlock FD, and then FPT flash entire BIOS anytime without hassle)
If you do get into doing this, dump your BIOS region, mod that, then flash it back, don't flash stock BIOS anything with FPT or you can loose serial, UUID and LAN MAC depending on how you flash.
If you need help doing this let me know, I will show you the way.

@3dsmaxer30 Another alternative would be to move the boot NVME drive to one of these https://www.ebay.nl/itm/1-NVMe-M-2-NGFF-...rEAAOSw4ThdED63

FPT dump/edit/flash should work, programmer shouldn't be required.

Hi guys, sorry for the delay.
I was pretty bussy with some jobs and had no time to try some stuff.
What I've tried now, moving the bootable drive from the Asus Hypercard to a nother card to fit in the first slot - PCIE#1
Than I moved the Asus Hypercard to PCIE#5 and PCIE#7, but I wasn't able to see any M2 inserted. I switched on Bifurcation für IOU2 and IOU3, but I think, the nvme driver is just placed for CPU0 and not for CPU1.
Any Idea what I could try next?

So this is probably the reason, why the bootabledrive isn't even work in PCIE#5 or PCIE#7 at all, because he doesn't know how to handle this m2 card - because they just don't know each other...

CPU- or CPU1?? This board only has one CPU, that's confusing, not sure what you mean there.
I can't comment much on this, I have never used these cards, NVME, or bifurcation. But, I do doubt NVME module itself cares or is only coded to be able to use certain slots or CPU's etc, this kind of thing is all BIOS controlled.

@Lost_N_BIOS, the attached HWInfo screenshot looks like it's from a dual-socket system. PCI-buses #0,#127#128... and not visible in the image ist PCI-bus #255.
My X79 board appears in HWInfo with buses #0 and #255 only, the Z9 like mentioned before with four buses.

There is Asus P9X79 with two sockets?

Not that I know, I think @3dsmaxer30 uses a Z9 board.

Sorry for confusing. I didn't start a new thread for my board with c602 chipset. It's a asus z9ped8 ws with c602 chip and dual socket system

@3dsmaxer30, I use the same model.
Interesting that the Root Ports of CPU2 (#1) are displayed differently in your HWInfo Screenshot than in mine.

@3dsmaxer30 Bifurcation seems to be working since on the second CPU bus128 port 2a 2b 2c 2d do show up. The problem cannot be an NVME driver since you dont need one for basic function of NVME storage. Windows has a basic NVME driver (which isnt needed for it to show up in HWiNFO.
To be sure I would try to enable x4x4x4x4 bifurcation for both the x16 slots connected to the 2nd CPU, Move the NVME carrier card from the bottom slot incrementaly to the 4th PCIe slot from the top and check every IIO on PCIbus 128 if any NVME drive shows up anywhere every time you move the card.
If that doesnt work maybe the traces on the motherboard to the second CPU are longer and you can to try Extended Synch under Advanced/PCi Subsystem settings/PCi Express Settings to try to make it work. Beware some of these some of the settings her caused my machine not to boot and required a CMOS clear and total cold boot.
If you lack this PCi Subsystem settings/PCi Express Settings menu in bios i can unlock it for you if you provide your current bios.
Good luck.
