Intel's Advanced Host Controlled Interface (AHCI) helps your computer interact with its hardware. It defines the way your computer works with devices such as your hard drive and optical drive that use a Serial Advanced Technology Attachment (SATA) interface. Enabling the AHCI subsystem lets Windows use the higher speeds that SATA interfaces allow. PCs running Windows, including Dell Precision workstations, enable AHCI through the Windows Registry Editor.
