Intel DQ77MK User Manual page 27

The PCH supports the Serial ATA Specification, Revision 3.0. The PCH also supports
several optional sections of the Serial ATA II: Extensions to Serial ATA 1.0
Specification, Revision 1.0 (AHCI support is required for some elements).
The underlying SATA functionality is transparent to the operating system. The SATA
controller can operate in both legacy and native modes. In legacy mode, standard IDE
I/O and IRQ resources are assigned (IRQ 14 and 15). In native mode, standard PCI
Conventional bus resource steering is used. Native mode is the preferred mode for
configurations using the Windows* XP, Windows Vista*, and Windows 7 operating
systems.
NOTE
When an mSATA module is plugged into the PCI Express Full-Mini Card slot, SATA port
4 (colored gray) will be disabled automatically.
NOTE
Many SATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.
