How to enter RAID configuration on SuperMicro X11SPH-nCTF

[centaur]

Hello everyone,
I successfully installed OS on my SuperMicro X11SPH-nCTF and now I can't see CTRL-C or CTRL-I during boot sequence, so I can't enter RAID configuration of Intel RAID controller or SAS3008 SAS controller.
I tried to disable all boot devices but the only difference is that I receive message no bootable device found.

Do you have two drives connected to that controller? I had the same problem when I only had one drive connected.

Yes, there are multiple drives on both controllers.
