Hi folks!
I finally get this thing to work!
With this bios:
As it turns out the BIOS was good from the start.
Bifurcation was working by default.
The reason it wouldn’t work for me was because I had an M.2 card in the M.2 slot all along.
When I was browsing the motherboard description I noticed that even with a 40 lane cpu the PCI-E 3 slot can’t work in 16x mode. (If the onboard m.2 slot is occupied)
So I removed the ssd from the motherboard M.2 slot and put it into the HYPER V2 card, put the Hyper V2 card to the PCI-E slot and voila!
The system saw all 4 M.2 SSDs at once!
And the resizable bar still work as it should.
So, important notification for those who want to use this bios with 4x M.2 pci-e card:
The bifurcation only work in the PCI-E 3 slot, and with empty onboard M.2 slot.
And no further bios settings needed.
Thank you for the support all of you guys!
I have Asus X99 Deluxe II, 6950x, Asus Hyper M.2 x16 card with 4 different ssd (one system bootable)
