@ Lost_N_BIOS no luck with the 3rd BIOS. It bricked the MB instantly . I found the original BIOS (not MOD) and I tested to write to the BIOS chip, it's back to the original from the beginning, no more error message " press F1 to resume". I attached, Please have a look.. Thank you.

@Jen - I wonder what's going on here! Maybe your NVRAM in the dump you made is also messed up, I didn't consider that and assumed only the bad edit caused non-boot, I didn't think it corrupted anything but it seems like it did.
Original BIOS (or original FPT dump) cannot be used that way, well it can but it's (FPT) missing an entire NVRAM volume (Stock original BIOS missing all that + 95% of main NVRAM volume).
There is also info in a padding file that is not in stock BIOS, is not included in below BIOS, we'll re-insert in a later test, in case this is some corruption

Please test this, it's UnlockFinal.00 that you already confirmed OK/working, right before you reminded me I forgot about all the other updates.
This is UnlockFinal.00 + your dumped NVRAM volumes, if this does not boot then we know your dumped NVRAM also messed up

This contains two of same BIOS, with all same, except one NVRAM volume state I change from F8 to F0 (This is usual how it is when these values used, but in your dump both were F8)
If both these fail, then we know your dumped NVRAM from the bricked BIOS is bad, and we'll have to move forward with the single NVRAM volume backup like you're using now.
Sorry for all the hassles here, I didn't expect your dump would be messed up other than the bad edits, which I removed all of last time, but I guess something else is messed up too.
Please test both, and let me know outcome of each, and actually, in case it's needed, here is same two files with that padding added back in that I mentioned above
http://s000.tinyupload.com/index.php?fil...613671478254821

So please test all four and let me know, if either of first two work, keep going and test last two as well, since I assume this info should be in BIOS unless it's actually some corrupted info.
If only one of first two works, then only test matching # one from second set above.

@ Lost_N_BIOS Thank you, I'll try and will let you know..bye for now

You're welcome! Sorry for all the BIOS and testing hassles, and this just to get going too But, I'd like to get your BIOS going on complete BIOS, before we do the other tests to add in the updates and find the issue with those.
We'll get there, hope you can bear with me while we figure it all out

@ Lost_N_BIOS Please don't apology, I'm the one thank you very much for your time and effort, We'll get there adventurously..

It's OK, I feel bad for giving you BIOS that bricked your board, and now all these other BIOS still keep failing.
I think your dump was more messed up than I initially thought, but hopefully we can sort it out and use the parts I wanted to salvage (NVRAM Mainly)
You're welcome, I promise once we sort out this initial "get you going again properly" then the rest of test BIOS I send you to figure out the issue will be single test (ie test of NVME insert x2 BIOS only, test of microcode x2 BIOS only, ME Insert at end which hopefully will be OK)

@ Lost_N_BIOS I tested 2 PAD.roms, they're both working in UEFI utility, it seems the BIOS MakeItRun4-2PAD has few more options then MakeItRun4-1PAD, but both of them don't show ME firmware version numbers just show N/A (maybe corrupted). Thank you

@Jen - What about first two BIOS, you were supposed to test those before any ones with "pad" in name? What do you mean more options? Please be specific about what settings, and which BIOS.
I was hoping you'd have a report, but sounds like you've tested BIOS all out of order, so not ideal for what I needed to find out. You should test 1 + 2 out of first set, then if only one works or only one looks correct, only test next the same # with pad in name also.
ME FW, we're not addressing here, but since it's stock it should be OK, may need a -greset (but, for now, do not worry about this)

None of this is meant to be a mod BIOS or address any of the update/fix stuff (however, this does have the unlocked menu I did for you).
The main thing here is to get you back up and running properly with full NVRAM volumes, so you have a good starting point other than your bricked dump.

@ Lost_N_BIOS I'm sorry I only tested 2 BIOS in the post #47. I didn't know you mean I need to test the BIOS MakeItRun2 post #41 and MakeItRun3 post #45 again, Is that right ? if yes I'll start again and let you know.. sorry.

Sorry @Jen - looks like I left off the first link for first set of two, so sorry NO, I meant for post #47 to have two sets of BIOS, I just forgot to add first package link

@ Lost_N_BIOS I tested 4 BIOS all login UEFI setup utility working normal no issues, that is how far I can go (sorry my knowledge is limited) , but all 4BIOS don't recognise my Samsung M.2.SSD 970 PRO 1TG, it only recognised samsung M.2.SSD 950 PRO 500GB. I tried all combination connections, Example..each M.2.SSD driver on single PCIe M.2 adapters to a single PCIe port and connect 2 M.SSD drives on Asus Hyper M.2 x16 Card to the bottom PCIE slot in x4x4 mode, still doesn't recognise the 970 PRO drive, but when I try clean install WIN 10 x64 the 970 PRO show up then I installed. Finishing installation, restart windows doesn't boot up, 'cause the 970 PRO is not recognise in the BIOS. Please help, sorry for take so long to do the tests. Thank you

Did you manage to resolve this, I'm looking for nvme and bifurcation support for asrock x79 extreme 9...

@Lost_N_BIOS,

I read the whole post/conversation because i am searching for a way to unlock nvme and bifurcation support for asrock x79 extreme 9.
Seeing the difficulties you had with Jen, did you guys solved the issues and have a good complete working Bios?
Like Jen i am a beginner in all of this, don't know much about editing bios but i am willing to help any way i can.

Or is it save to follow the '[Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS" for the asrock x79 extreme9.

Hey guys if you are the beginners like me just stick to the [Guide] How to get full NVMe support, unless you're advance users, because I did bricked my BIOS, then I replaced a new BIOS from ebay and follow the [Guide] in the forum, then you'll be happy :).
Thanks very much Lost_N_BIOS again for trying hard to help.

@Jen - sorry, I don't see what the issue is, and you've not explained things very clearly above so not sure what you mean.
And as mentioned at #53, the 4 BIOS I sent you before were only for testing, and to get your system back up and running from being bricked. I did not do anything else to them, which you may have requested earlier.
After that, you need to go back in and flash in previous BIOS I made you via Instant Flash (ie post #18, or this one below)
Then for multiple NVME, you need to figure out which setting in BIOS applies to which slot on your board with HWINFO "BUS" area, then you know which one to bifurcate later and then you can install second NVME on the hyper card.
And, you may need to use certain slot on the card for only two drives, not sure, check it's manual and confirm if it matters or not.

@Fwb73 - See below
@BlazingJ - Use BIOS from Post 18, this is final unlocked BIOS without ME FW update (if you want that, then update ME FW via ME FW update tool in windows)
If you need that NVME edit already done, here is BIOS #18 + NVME and ucodes updated, WITHOUT ME FW update which caused the brick after 24 -
