your hard disks as RAID arrays, or just use them as single disks.
Before installation, you must remove all the Hard disks, which are not physically attached
to RAID controller, from your system.

make sure the RR Series controller EFI will be loaded firstly. If not, try to move it to
another PCI slot. Otherwise you may be unable to boot up your system.

In your system EFI SETUP menu, change Boot Sequence in such a way that the system
will first boot from EFI CDROM or EFI a Bootable USB drive, after you finish
installation, set RR Series RAID as the first boot device to boot up the system. Refer to
your motherboard EFI manual to see how to set boot sequence.
