The Advanced Host Controller Interface (AHCI) is a programming-specification which defines the operation of Serial ATA host-controllers (also known as host bus adapters) in a non implementation-specific manner. The specification describes a system memory structure for computer hardware vendors in order to exchange data between host system memory and the attached storage-devices. AHCI offers software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. AHCI is separate from the Serial ATA-II standard, although it exposes SATA's advanced capabilities (such as hot-plugging and native command queuing) such that host-systems can utilize them. Lately, several problems occur due to AHCI
- Enabling AHCI in a system's BIOS will cause a 0x7B Blue Screen of Death (BSOD) STOP error (INACCESSIBLE_BOOT_DEVICE) on installations of Windows XP and Windows Vista where AHCI/RAID drivers for that system's chipset are not installed; i.e., boot failure.
- For Intel chipsets (for example, Intel ICH9) drivers are available from either an OEM motherboard or computer manufacturer. For the Intel versions, the driver must be loaded before loading the OS (by pressing F6 as setup starts, then using the floppy disk when prompted). The Intel drivers will work for both XP and Vista. Also, in the case of ICH9, an unsupported method to enable AHCI on ICH9 is available.
- When attempting to install Windows XP or a previous version on an AHCI-enabled system, setup will fail with the error message "setup could not detect hard disk drive..."
- Windows Vista installation process may take several hours on a system that uses an AMD/ATI SB600 Series chipset operating in AHCI mode
In order to stop the Blue Screen of Death reappeared when installing Windows XP, first you need to disable the AHCI on BIOS setup. This can be done by pressing F2 button then at the BIOS system configurations select IDE mode for hardisk before you installing Windows XP.
