Windows 8 standard ahci 1.0 serial ata controller driver driver#
On Windows Vista and Windows 7, this can be fixed by configuring the msahci device driver to start at boot time (rather than on-demand).

(It may also be necessary to load chipset-specific AHCI or RAID drivers at installation time, for example from a USB flash drive). As an interim resolution, Intel recommends changing the drive controller to AHCI or RAID before installing an operating system. Technically speaking, this is an implementation bug with AHCI that can be avoided, but it has not been fixed yet. In Microsoft Windows the symptom is a boot loop which begins with a Blue Screen error, if not rectified. The most prevalent symptom for an operating system (or systems) that are installed in IDE mode (in some BIOS firmware implementations otherwise called 'Combined IDE mode'), is that the system drive typically fails to boot, with an ensuing error message, if the SATA controller (in BIOS) is inadvertently switched to AHCI mode after OS installation. Although this is an easily rectifiable condition, it remains an ongoing issue with the AHCI standard.

Some operating systems, notably Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10, do not configure themselves to load the AHCI driver upon boot if the SATA controller was not in AHCI mode at the time the operating system was installed. Windows XP and older do not provide AHCI support out of the box. Older versions of operating systems require hardware-specific drivers in order to support AHCI. DragonFlyBSD based its AHCI implementation on OpenBSD's and added extended features such as port multiplier support. But the chipset SATA interfaces may emulate more than one "IDE controller" when configured in IDE Mode.ĪHCI is supported out of the box on Windows Vista and later, Linux-based operating systems (since version 2.6.19 of the kernel), OpenBSD (since version 4.1), NetBSD (since version 4.0), FreeBSD (since version 8.0), macOS, GNU Mach, ArcaOS, eComStation (since version 2.1), and Solaris 10 (since version 8/07). When a SATA controller is configured to operate in IDE Mode, the number of storage devices per controller is usually limited to four (two IDE channels, master device and slave device with up to two devices per channel), compared to the maximum of 32 devices/ports when configured in AHCI mode.

Legacy mode is a software backward-compatibility mechanism intended to allow the SATA controller to run in legacy operating systems which are not SATA-aware or where a driver does not exist to make the operating system SATA-aware. Intel recommends choosing RAID mode on their motherboards (which also enables AHCI) rather than AHCI/SATA mode for maximum flexibility. Many SATA controllers offer selectable modes of operation: legacy Parallel ATA emulation (more commonly called IDE Mode), standard AHCI mode (also known as Native Mode), or vendor-specific RAID (which generally enables AHCI in order to take advantage of its capabilities).
The current version of the specification is 1.3.1. For modern solid state drives, the interface has been superseded by NVMe. AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities (such as hot swapping and native command queuing) such that host systems can utilize them. AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. The specification describes a system memory structure for computer hardware vendors to exchange data between host system memory and attached storage devices. The Advanced Host Controller Interface ( AHCI) is a technical standard defined by Intel that specifies the operation of Serial ATA (SATA) host controllers in a non-implementation-specific manner in its motherboard chipsets. content /www /us /en /io /serial-ata /ahci.
