Advanced host controller interface is a mode that a serial advanced technology attachment device can emulate. The ASUS P5N7A-VM motherboard can run SATA hard drives in AHCI or integrated drive electronics mode. AHCI mode works with Windows Vista, Windows 7 and Linux with kernel 2.6.19 and greater. AHCI mode also enables special features on the SATA hard drive; activating AHCI mode on an ASUS P4N7A-VM will enable hot swapping, allowing you to switch SATA devices while the computer is turned on, and native command queuing, which optimises disk performance. To change a SATA hard drive from IDE mode to AHCI mode, boot in to the motherboard's basic input/output system software at start-up and change the device's mode options.
