The IT8212 is a PATA controller not SATA. I guess they may have wired
SATA bridges to it.

It does. One thing worth noting is that the chip has two modes. In the
RAID mode it doesn't support CD-ROM devices but handles basic raid stuff
itself via its embedded microcontroller. In non-RAID mode it behaves
exactly like a standard IDE controller. Both modes are supported. RAID 0
is generally best done using software RAID in Linux, RAID 1 there are
advantages to doing it either way. Some of the RAID firmwares are a bit
flakey so if you get a problem boot it with the device in non-RAID mode.
(if the BIOS won't let you set it then try 'pata_it821x.noraid=1' as a
boot option.
