Hello dears!
A few years ago I managed to insert the string NvmExpressDxe_4 in my BIOS F5F following a tutorial here on the site and it was very useful for me to get this MOD done.
But the need arose to use more storage on SSD and I ended up buying a 4x NVME M.2 card on aliexpress thinking i would work more than one SSD, and I've been trying for several months to follow another tutorial here on Bifurcation and I confess that it's very difficult for me due to the hidden information that my BIOS has and the little knowledge. Honestly I'm exhausted :(
Are any enlightened people able to help me on this mission? Thanks for listening!

@orgun please give us the full memory dump of your bios.

Wow men! thanks for the quick reply!!!
My BIOS is already with NvmExpressDxe 4. Is there a problem?

CPU: Intel Xeon E5 2696V2 Mobo: Gigabyte GA-X79S-UP5-WIFI (rev 1.1) RAM: Micron 8x4GB DDR3 1867Mhz GPU: Saphire Radeon RX560D Drive: ADATA S11 PRO 512GB: ADATA S11 PRO 1TB: Networking: BCM4360 802.11ac

From my understanding your buying a 4x nvme adapter which i guess its a 4 slotted one in 1 card, correct? and you want to do x4x4x4x4 bifurication?

Yea! in the first slot x16

Hey, friend!
success!!!
some details:
1 - my first X16 slot counted as the layout of the board is the IOU2 and in this I enabled the bifurcation, but as in photo 1, it only appeared one SSD connected but as if it were in the last connection of the NVME card.
So I had the idea to invert the two SSD's M.2 to the end of the card, the two were recognized as shown in photo 2;

2 - I noticed that reading and writing was a little impaired. This is normal? or we have how to adjust! (See the crystaldisk photos)
But we have evolved a lot! thanks for the great help! :D
