[Guide] Adding Bifurcation Support to ASUS X79 UEFI BIOS

BIOS/UEFI Modding BIOS Modding Guides and Problems
116

Hi guys,
I tried every single configuration config with 4, 3, 2, 1 and 0 expansion cards.
And predicted by your knowledge was an IM.

Found an incompatibilty mixing the LSI card and Intel on same IOU and the Intel wasn’t detected by the board.

I found that the order of the names are mixed everywhere:
IOU1 -> x8(x4/x4) PCIE5 2.0 and PIKE 3.0
IOU2 -> x16(x8/x8) PCIE3 x8 3.0 and PCIE4 x16 3.0
IOU3 -> x16(x8/x8) PCIE1/MIO x8 3.0 and PCIE2 x16 3.0


I’m considering a PLX card like HighPoint SSD7101A-1 $$$$, no limit on x16 link to cpu or an Asmedia 2824 x8 link to cpu $$.
Any recomendation? Thanks.

Changing the board is even more expensive.
