PCIe Bifurcation on Fujitsu D3402-B21

[StancuFlorin]

Hello,

I have a Fujitsu D3402-B21 motherboard paired with an Intel Core i5-6400 CPU and is used to run unRAID.

I want to configure the main PCIe slot that is directly connected to the CPU to run as 1x8+2x4 since the CPU supports this [1].

The problem comes with the motherboard BIOS since I don't have any option to enable the PCIe bifurcation. The latest BIOS can be found here [2].

There is any way to to change the BIOS to enable PCIe bifurcation?

Thanks!
