I have double checked again and yes it's Fakeraid from LSI. Also it's not shown in "lspci -nn" output.

In your original message, you indicated that this was a PCI card, but it looks like this is just a firmware component of your motherboard.

I think you should assume that this firmware is unsupported. Set your SATA mode to AHCI in the BIOS, and then use "dmraid -r -E" to remove the RAID metadata from those disks: https://bugs.centos.org/view.php?id=9813

You should be able to install using Linux software RAID.
