Thanks very much for that contribution! Just one little question: Slot 6 is not 16x, or is it? So what would the bifurcation option be there? 4x/4x?Hi all,
I recently acquired one of these boards, and I figured I would share my modified BIOS (attached) since this thread has been helpful to me. I have enabled bifurcation options for all the slots connected to CPU2 (Slots 5, 6, 7). The settings can be configured from within the BIOS and are named in a coherent fashion (IntelRCSetup->IIO Configuration->PCIEX16 Bifurcation).
I did try to enable bifurcation for the slots connected to CPU1, but I didn't have any luck. This may have to do with the fact that they are routed through switches for the x8/x8/x8/x8 vs x16/x0/x16/x0 functionality, but I didn't investigate further.
Let me know if you encounter any issues, etc. or if this is useful to you.
Thanks!

I am personally quite happy with bifurcation on the two 16x slots for CPU 2. Works just great for me now.
But having the BIOS option to switch it on/off is a nice addition.
