5.3.5 AHCI Configuration
NOTE:
Advanced Host Controller Interface (AHCI) is a new programming
interface for SATA host controllers. AHCI systems do not have
master/slave designation for SATA devices, each device is treated as a
master, and hardware-assisted native command queuing.
Use the AHCI Settings menu ( BIOS Menu 8 ) to report on the auto-detection of devices
connected to the onboard SATA drive connectors.
