Question Chinese motherboard not recognizing SAS card ?

[jiv808]

Hi everyone

I'm 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 Dell RTX 2070 video 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 motherboard model 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.

What SAS card is it?

If it's an old LSI HBA SAS card (or badge engineered version from Dell or HP) you might find the Option ROM (BIOS) on the controller card is not recognised at POST if the motherboard BIOS is set to UEFI-only.

If there is a Legacy boot option in the BIOS, try Legacy first, UEFI second. That way the motherboard might find the controller ROM(s) on the plug in cards and display their welcome text as soon as the system starts.

On some of my machines, when correctly configured, I'll see the LSI HBA BIOS text first, then the 10GbE SolarFlare NIC BIOS, then the motherboard's AMI BIOS text, spaced roughly 10 seconds apart. Next, I'll get the Windows splash screen with a rotating circle of dots underneath, before the login screen appears and finally the Desktop.
