@kosh06 - you can directly edit in place with AMIBCP, like you were doing in your thread, you do not have to edit this way unless you want to.
And, as I mentioned, not all ports/slots in BIOS will be same for your board, you will have to try each one until you find which slot on your board is which slot in the BIOS, then move your drive to the slot that offers the settings you need/want to use.

Here is all your available options - the setting choice you keep mentioning, does not offer the split choices you want, so you will need to try another slot/setting position

@Kosh06
Were you testing if bifurcation works with RU (which is optional) with the x16 (x8 electrical) bottom slot?
You seem to have the same layout as my P9X79 and assuming they did not change it, the bottom x16 slot is IOU1(x8 electrical) the middle one is IOU2 the top one is IOU3.

thank you for your answers I look back home tonight I come back to you to tell you if it works

@kosh06
I modified your BIOS for you to enable the options for bifurcation you can find them under Advanced > System Agent Configuration > IOH Configuration > IOU? - PCIe Port Where ? is the port number counting from the bottom up.
Download the bios
Format a USB pendrive to FAT32.
Extract the BIOS file and rename the file to SABERX79.CAP.
Put the BIOS file on your USB pendrive.
Shut Down your PC
Connect the USB pendrive to the white USB Port.
Press the Bios Flashback Button for three seconds until the LED begins to blink, then release.
Wait until the LED stops blinking.
Power on your system.

Good evening, after updating the bios, the pc can not find the SSd M2 disk.

I had to put an old disk and install windows on it to put the bios ajour with the nmve driver.
My flas back button does not work anymore I had to pass for the utility from Asus.After a little research on the downloaded file, I have not seen a driver for SSD M2, or they are hidden

@kosh06
The bios I provided does not contain an NVME startup module just the bifurcation options enabled in bios. None is needed if you dont use NVME for windows.
However I made you one with NVME boot.

If your flashback button does not work I highly recommend getting a hardware BIOS flasher in case of failure to boot, before flashing.
I am curious however how you flashed a modified BIOS without flash back button since the BIOS did not have a valid checksum.

@JackSted

Hello, just to answer your question about the Flash Back button, I read some by on the forum, use AI Suite2 software start with the original Bios and before flash replace for the file edit.

I'm testing the file.

Thank you

Hello,

A big thank you to both of you, now I see both SSD M2.J 's just had to change the M2 of place so I have two disks on the first two ports of the Hyper M2 card.

Now next step mount RAD both discs.
I'm going on vacation until the end of the week. I'll be back next week, to tell you if everything is going well.

For the little story of Flash Back, I took a usb key that is scary to see and disable UEFI in the bios.

Another big thank you.

Congrats on your progress. Let me know how it turns out :D

^^ There it is x 2 ^^

Hi,

i instal you BIOS on my x79 sabertooth motherboard work nice. Only i does not see "PCI Subsystem Settings".
Can you please make change with that support, Enabling in you last BIOS version with suport for NVME boot and bifurcation options enabled.
Thanks you JackSted

And my next step is make raid0 with ASUS m.2 x 16 v2 + 4xVNand. I hope I will succeed.

@1000 - use @JackSted BIOS on page one (or in his signature link)

That BIOS for Asus P9X79 i have SABERTOOTH-X79-ASUS motherboard. I tray and i have error with update.

that version is work me without "PCI Subsystem Settings".

@1000 - then you are posting in the wrong thread, you can't use the BIOS here, sorry I missed that on my earlier reply If you are using the non-sabertooth BIOS on your board, that's OK if you want, but you want the one I mentioned (from first post or in JackSted's signature)

What do you need, Sabertooth BIOS with NVME Mod + PCI Subsettings (or full unlocked BIOS?)
