I have been having some problems with hardware RAID 1 on the motherboard that I am running CentOS 7 on. After a BIOS upgrade of the system, I lost the RAID 1 setup and was no longer able to boot the system.

The Intel RST RAID (aka Intel Matrix RAID) is also known as a fakeraid. It isn't a hardware RAID, but instead a software RAID that has a fancy BIOS interface. I believe that the mdadm tool can examine the RAID settings, and you can look at /proc/mdstat to see its status, although from what I remember from previous posts, it's better to just let the BIOS think it's a JBOD and use the linux software RAID tools directly.
