What BIOS version is installed on the board? If not latest please update it from the following URL: https://downloadcenter.intel.com/download/26964/Intel-Server-Board-S1400FP-Firmware-Update-Package-for-EFI?product=61079
After BIOS is updated please disable quiet boot, then select RAID mode and set it to ESRT2 then disconnect both the drive cables. What is the outcome now?
It is possible that the board is not initializing the RAID controllers.
Hope this helps
