Hi everyone

Mucking around with 2 Xeon multicore CPUs and a Chinese ZX-DU99D4 v1.3 motherboard.

Chipset is X99. Problem I'm having is getting my SAS controller card recognized before the PC POSTs into its BIOS.

There are 2 PCIe x16 slots on this board. I can get a display when my video card (Dell RTX2070 card) is in the 1st (upper most) slot AND I can get a display when the card is in the 2nd (lower) slot. So there is no issue with the 2nd slot not working.

I know these cheapie boards can be tricky to set up or simply not work. Does anyone know if/what settings I should check in the BIOS to get the SAS card recognized?

I've tried Googling the board number but there is little info out there. Someone has done some BIOS hacks but my BIOS is a later version so doesn't need the hack.
