Hi,

I would like to ask that someone mods the latest 4801 BIOS with the latest NVME drivers. As a new member I can't post the link to the ASUS download web page but you can get the BIOS from there.

I followed [OFFER] P9X79 PRO BIOS Modded for NVMe SSD (sorry I can't link the topic) but the BIOS from OP is already from 2018. @Fernando's BIOS was removed from post #239 and the one that @Lost_N_BIOS mentions in post #256 has a non-working URL.

Thank you so much!

@st0nedpt - Merging with the main thread. Please tell me the post # of the BIOS you need working link for, I will add mirror (tinyupload has been down for week+, otherwise URL would be working )
BIOS from post #115 has NVME mods ONLY, you want one with bifurcation. I will try to find in thread which post # has PRO BIOS w/ bifurcation and add new mirror to that post
----------------------------

@strijem - PATA SS means NVME mod was successfully flashed, you just then need to follow step #4 of this guide to install OS to NVME - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS
But you need NVME + Bifurcation mod BIOS from this tad - [OFFER] P9X79 PRO BIOS Modded for NVMe SSD
On ALL Asus X79 you can only run x3 NVME on any slot, some limitation
Merging your posts to that thread now - I will link you to PRO NVME + Bifurcation mod BIOS as soon as I find it in here and add a mirror link to the post

--------------------

@st0nedpt @strijem - I could not find the post where I've added this here, but I know I posted sometime in April due to the date?
Anyway, here is Asus-P9X79-PRO-Asus-4801-NVME-SASwitch-Bifurcate_Mod - Follow guide above at step #4 in the "This is what you should do" section after you install BIOS
Flash via USB Flashback only - https://www.sendspace.com/file/asav9r

@st0nedpt - You're welcome! See my edit above, I added new link for 4801 NVME mod BIOS (+Bifurcation mods) before you posted that reply
If you just need NVME mod, no bifurcation, then you want this package instead, sorry for any confusion above! (Flash via USB Flashback ONLY) - Asus-P9X79-PRO-4801-Stock-NVME-Mod-ONLY
Bifurcation has modified BIOS menus, so you can control use of more than one NVME on a single PCIE adapter card

@Lost_N_BIOS HI, I'm looking to mod my P9X79 PRO with the 4801 build but the last link you posted doesn't load, can you please link again?
Also this is the SSD and adapter I'm looking to get, will these work ok?, Thanks for your help

Vantec M.2 NVMe + M.2 SATA SSD PCIe x4 Adapter (UGT-M2PC200)
Samsung 970 EVO Plus SSD 1TB - M.2 NVMe Interface Internal Solid State Drive with V-NAND Technology (MZ-V7S1T0B/AM)

@iNinja - Sorry about that, if you meant link in post #274, I fixed it now (it was OK link, just badly coded in there, I switched URL and text) @st0nedpt
Yes, UGT-M2PC200 will work for a single NVME, make sure you put the NVME into correct slot for NVME not AHCI/M2 type - You want to put 970 into bottom NVME slot

@Lost_N_BIOS Thanks for getting back to me so quick, would you recommend another adapter? as the UGT-M2PC200 will come from another country which will take some time.
Here are a few others i can choose from,
https://www.pccasegear.com/products/4513...with-slot-cover
https://www.pccasegear.com/products/5128...x4-adaptor-card
https://www.pccasegear.com/products/4513...with-slot-cover

Is post#249 the best guide to use when i receive the parts?

Thank you

@iNinja - These are the ones I use From Amazon, just as good and much cheaper, maybe you can find?
https://www.amazon.com/gp/product/B07GPBBCGS
https://www.amazon.com/M-key-Adapter-XP9...1/dp/B07GNDR81B

What you linked, 1st and 3rd is same, but both of those would work too but that is way overpriced.
Ohh! you are in AU? If yes, sorry, not sure where would be quick place to get an adapter, maybe what you linked is best option to get fast?
Or, maybe you can find ones like I linked at some shop you know there? You can get those I linked on ebay for $3 from China too, but you know, 3-5 week wait

Any will do, just make sure it's PCIE and allows NVME x4 speed through it.

Yes, Post #249 will help you do USB Flashback. File should already be P9X79PRO.CAP, this is the only file name it will read/find. If you have never done USB Flashback, you may need to try a bunch of USB drives before you find one that works, not all are compatible.
Smaller, older, cheaper = better for this. 128Kb-2GB, USB 2.0, formatted to FAT32 - If you only have larger/newer USB, sometimes if you format down to 1GB it will work, but generally digging around in a drawer to find old, lost/forgotten USB will be the one that works

You also need to follow info at post #4 of this guide in the "This is what you should do" Section
[Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS

@st0nedpt - Nice you noticed the link error and were still able to grab the file
You're welcome, great to here the install went smoothly!

Sounds like good NVME speeds to me As for the PCIE graphics card lane width, move your NVME to another slot that is not shared with the graphics card, then it will go back to x16

@Lost_N_BIOS

Hi;
Thanks for upload #274.
I flashed my mobo and it went smoofly.

I have another problem :

I wanted to try Twister's version from post #12 (thanks @Twister) and I got "Security verification failed"
I get the same message when I want to re-flash with your version again (my mobo runs actally on it)

Twister modified also Marvell firmware :
"....
· updated OROM Marvell 88SE9128 1.0.0.1031 -> 1.1.0.1002
updated EFI Marvell SATA AHCI 1.1.0.1001 -> 1.1.0.1020
...."

Marvell controller 9128 on Asus board slows down significantly ssd-drives (ports Sata 6G_E1/E2 gray). Speed is below SATA-2 !!!
I prooved it with Samsung 840 PRO and after I plugged it into Asus SATA 6G_1/2 port, its speed rose 3-times !

Please help:
- how to bypass "Security verification failed" problem
- if possible update BIOS for P9X79PRO with Marvell firmware which doesn't harm other mobo functionalities (LAN, boot etc)

So I tried the BIOS from #274 and the flash worked on first try.
I used a cheap "nvme to pcie" adapter from aliexpress so for anyone wondering I think anything will likely work.
My SSD was a XPG GAMMIX S11 PRO
To get OS booting I followed some of the suggestions which were:
- Disabled Fast Boot
- Set SafeBoot to OtherOS
- Set Compatibility Support Mode (CSM) to Disabled
This worked to install a fresh copy of Windows from which I am typing now.

I previously tried migrating all the partitions from my old MBR SATA SSD to the new GPT formatted NVME SSD but this did not seem to work. To those that want to try this, good luck and let me know what you did to succeed.

MotherBoard Asus P9X79 PRO
Bios version 4801

Hi Everybody,

Please someone can help me for to make disk Samsung EVO970 NVME 2 on Asus P9X79 PRO WITH WINDOWS 10 PRO.

I downloaded 3 Modded Bios on this website and flashback the Bios with both all 3 Modded Bios.

Unplug all Sata Disk.

Method 1: Secure boot=Disable, Fast Boot=Disable, CMS=Enable, Boot device control = UEFI and Legacy OPROM, Boot from network=Ignore, Boot from Storage Device= UEFI driver first, Boot from PCIe=UEFI Drivers Frist

Method 2: Secure boot=Disable, Fast Boot=Disable, CMS=Disable

Method 3: Secure boot=Enable, Fast Boot=Enable, CMS=Enable, Boot device control = UEFI only, Boot from network=Ignore, Boot from Storage Device= Both UEFI first, Boot from PCIe=UEFI Drivers Frist

My problem:

1- IN THE BIOS, I DON’T SEE A NEW PATA SS (Samsung 970 EVO).
2- Boot on USB key Windows installation, Windows see the disk and installation was successful.
3- After Windows installation, the computer reboot but don’t find the Disk and any BOOT DEVICE
4- I CHECKED AGAIN THE BIOS, BUT DON’T SEEK THE PATA SS

I don’t know what I missed, if there are the right Modded Bios works ?

Thank you in advance for your help.

Thank you very much for your help.
