Table 3 Computer Setup-Storage (continued) drive can accept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256. The number of sectors per track may not exceed 63. These fields are only visible and changeable when the drive translation mode is set to User. Default Values IDE/SATA Allows you to specify the default values for the Multisector Transfers, Transfer Mode, and Translation Mode for ATA devices. Storage Options Removable Media Boot Enables/disables ability to boot the system from removable media. Legacy Diskette Write Enables/disables ability to write data to legacy diskettes. BIOS DMA Data Transfers Allows you to control how BIOS disk I/O requests are serviced. When Enable is selected, the BIOS will service ATA disk read and write requests with DMA data transfers. When Disable is selected, the BIOS will service ATA disk read and write requests with PIO data transfers. SATA Emulation Allows you to choose how the SATA controller and devices are accessed by the operating system. There are up to two supported options: IDE and AHCI. IDE is the default option. Use this option for "normal" (non-AHCI) configurations. Select the AHCI 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. NOTE: Windows 2000 and Windows XP require a third-party device driver to access SATA devices using the AHCI interface. If you attempt to boot either of these operating systems in AHCI mode without the required device driver, the system will crash (blue screen). SATA 0 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. NOTE: Advanced operating systems like Windows may reenable the channel. SATA 1 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. NOTE: Advanced operating systems like Windows may reenable the channel. SATA 4 (some models) Allows you to enable or disable DOS and boot accesses to the Primary channel of the second SATA controller. This feature only applies when SATA Emulation = IDE. NOTE: Advanced operating systems like Windows may reenable the channel. SATA 5 (some models) 6 Computer Setup (F10) Utility ENWW

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 either of these operating
systems in AHCI mode without the required device driver, the system will crash (blue

SATA 0
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.
NOTE:
Advanced operating systems like Windows may reenable the channel.
SATA 1
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.
NOTE:
Advanced operating systems like Windows may reenable the channel.
