    MCP 2 doesn't have ANY SATA support. MCP have 6ch codec, 2xATA133,
    6xUSB2, 100Mbps ethernet, 6xPCI. MCP-T also have IEEE1394, SoundStorm
    support (I'm afraid it still unsupported, just 6ch codec too) and the
    interface for second 100Mbps ethernet (3COM). No SATA at all... Usually
    motherboard manufacturers add SATA controller (Silicon, etc) that allows
    to implement SATA support. Some puts GigE chip. But usually you need to
    pay a fee - one or more available PCI slots.
