3-10 Chapter 3: BIOS setup
Chapter 3
32Bit Data Transfer [Enabled]
[Enabled] Sets the IDE controller to combine two 16-bit reads from the hard disk
into a single 32-bit double word transfer to the processor. This makes
more efficient use of the PCI bus as fewer transactions are needed for the
transfer of a particular amount of data.
[Disabled] Disables this function.

SATA Mode select [SATA Mode]
This item appears only when you enabled the OnChip S-ATA Controller item and allows you
to select the SATA mode.
[SATA Mode]
Set to [SATA Mode] (or [IDE Mode], depending on the BIOS version) when
you want to use the Serial ATA hard disk drives as Serial ATA physical
storage devices.
[RAID Mode] Set to [RAID Mode] when you want to create a RAID configuration from the
SATA hard disk drives.
[AHCI Mode] Set to [AHCI] mode when you want the SATA hard disk drives to use the
AHCI (Advanced Host Controller Interface). The AHCI allows the onboard
storage driver to enable advanced Serial ATA features that increases
storage performance on random workloads by allowing the drive to
internally optimize the order of commands.
When this item is set to [AHCI], only SATA connectors 1–4 can be detected. Ensure that
you’ve installed the AHCI driver, so that you could use SATA connectors 1–5 and E-SATA
connector in AHCI mode under OS.
