[REQUEST] Asus X99 Deluxe II Bifurcation 4x4x4x4

Hi there,

I am looking to get Bifurcation on my repurposed X99 Deluxe II board that is now a server.

I’d like to split PCIe1 from x16 to 4x4x4x4

Any, help, pointers etc are greatly appreciated, this would be a huge mod for me and save a 400$ adapter…

Here is the latest bios file:

Thanks!

Hi, did u get Bifurcation working?
Would be great to know, trying the same thing with the same board, found the tutorials but thought it wouldn’t be a bad idea to ask somebody who already did it ^^
Would be great if u could hmu ^^

No not yet… I’ve done the grub mod but like you. Either not doing something right or it’s just not “sticking”.

I tried over and over to follow these steps, but I’m dyslexic as fuck and it’s hard to follow. I’d love guidance on how to do it vs just a bunch of links. But at least there’s something.

Grub mod I’ve done was:

“setup_var IntelSetup 0x537 0x0”
