I do support the *hardware* that is the SiI3114 chip. That means you
will get access to the individual disks on the 4 SATA channels just like
any other (S)ATA controller.
Now the RAID "stuff" you are talking about is all done in *software* so
it depends on the BIOS type/vendor and what type of metadata it uses.
Software RAID's are supported from Promise/HighPoint/LSI as I stated
above, if thats not what you have the ATA driver doesn't know how to
pick up the metadata from the disks, and therefore doesn't know what the
RAID looks like.
However, atacontrol can create at RAID for you on any type of (S)ATA
controller, you just have to live with certain restrictions, se 'man
atacontrol' for details.
