Q10011901 - I created a raid10 on 4 ST2000NM0115 disks with a single 4TB volume. During POST the message appears that the controller BIOS is not loaded.

Legacy bios code does not support devices with 4k block size. Those drives are 4kn model so the volume will use 4k size. This is the reason you saw bios not installed message. Please configure the raid card works with UEFI bios mode and also configures your motherboard to use UEFI to load option ROMs.
