Setup Utilities and Diagnostics Features Heading Option Description Storage (continued) Storage Options (continued) DPS Self-Test SATA Emulation Allows you to choose how the SATA controller and devices are accessed by the operating system. There are up to three supported options: IDE, RAID, and AHCI. IDE is the default option. Use this option for "normal" (non-RAID, non-AHCI) configurations. Select the RAID option to enable DOS and boot accesses to RAID volumes. Use this option for RAID configurations under Windows 2000, XP, or Vista with the appropriate RAID device driver. ✎ The RAID device driver must be installed prior to attempting to boot from a RAID volume. If you attempt to boot from a RAID volume without the required device driver installed, the system will crash (blue screen). Also, do not select the RAID option while the DriveLock feature is enabled on any attached hard drives. Doing so will cause the DriveLocked drives to remain locked and inaccessible during subsequent reboots until another SATA emulation mode is selected. Select the ACHI option to enable DOS and boot accesses to SATA devices using the AHCI interface. Select this mode if the target operating system supports accessing the SATA devices via AHCI (e.g. Windows Vista) and AHCI accesses are desired. ✎ Windows 2000 and Windows XP require a third-party device driver to access SATA devices using the AHCI interface. If you attempt to boot with either of these operating systems in AHCI mode without the required device driver, the system will crash (blue screen). SATA 0 and 2 Allows you to enable or disable DOS and boot accesses to the Primary channel of the first SATA controller. This feature only applies when SATA emulation = IDE. ✎ Advanced operating systems like Windows may reenable the channel. SATA 1 and 3 Allows you to enable or disable DOS and boot accesses to the Secondary channel of the first SATA controller. This feature only applies when SATA emulation = IDE. ✎ Advanced operating systems like Windows may reenable the channel. ✎ Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection System (DPS) self-tests. ✎ This selection will only appear when at least one drive capable of performing the DPS self-tests is attached to the system. ✎ Support for specific Computer Setup options may vary depending on the hardware configuration.
