We have X10DRL-C motherboard with 4nos Toshiba MG04SCA20EA drives and configured RAID10.
We are unable to select boot partition in raid controller webBios.
We are able to install OS but since the raid adapter is not seen in boot selection menu we are unable to boot into OS.
We have update system board BIOS to 3.2 and re-flashed raid controller firmware as well.
Also reset defaults was done on raid controller and reset to optimized default done on system board as well.
Please see attached snapshot and suggest further course of action.
Soft remind Toshiba MG04SCA20EA are 4kn format drive. Kindly to configure BIOS - Onboard SAS OPROM to EFI and with UEFI install OS.
