I was wondering if there was some type of feature that's 'hidden' in the BIOS for some X58 motherboards related to Bifurcation;
When looking at the datasheet for Intel's X58 chipset it references supporting bifurcation but references code, which makes it seem like this is something that I need to be able to configure in the BIOS and am unable to find any settings related to bifurcation in my P6T7 BIOS menu.
3.2.2.1
Port Bifurcation
The IOH supports port bifurcation using PEWIDTH[5:0] hardware straps. The IOH supports the following configuration modes:
• The width of all links are exactly specified by the straps
• The width of all links are programmed by the BIOS using the PCIE_PRTx_BIF_CTRL register (wait on BIOS mode)
