Question I am using the X10DAi motherboard with Bios 3.1. I bought the AOC-SLG3-2M2 and installed two M.2 devices and PCI-E slot #2 and set the Bifurcation for this slot to x4x4 in the Bios. however, the OS only sees one of the M.2 devices. How can I resolve this issue? Answer Please install the AOC-SLG3-2M2 on PCI-E slot #4 and then set the PCI-E bifurcation under Advanced >> chipset configuration >> North Bridge >> IIO Configuration >> IIO1 Configuration >> IIO1 Port 1 to "x4x4".
