AHCI Mode

The board supports AHCI storage mode via the Intel QS77 Express Chipset.
NOTE
In order to use AHCI mode, AHCI must be enabled in the BIOS. Microsoft Windows 7
and Windows 8 include the necessary AHCI drivers without the need to install separate
AHCI drivers during the operating system installation process, however, it is always
good practice to update the AHCI drivers to the latest available by Intel.
