Many motherboards that have more than two SATA connectors put two on the
SouthBridge's IDE-type controller, and the others on 'something else'.
Usually, the 'something else' shows as a SCSI controller in Linux. How many
SATA connectors are there?
I have seen a few motherboards use the Intel ICH ports as the first two, then
put either a Promise or SiliconImage controller on the board to handle the
other two or four ports (typically labeled as being 'RAID' ports). The ICH
will show as /dev/hdx, and the SiI or Promise will show as /dev/sdx.
