SATA Mode
IDE
AHCI
SW RAID
[IDE] – Supports up
to 4 SATA ports with
Parallel ATA
emulation
[AHCI] – Supports all
SATA ports using the
Advanced Host
Controller Interface
[SW RAID] –
Supports
configuration of
SATA ports for RAID
via RAID
configuration
software.
Allows the user to configure the system as
follows:
IDE: SATA Legacy IDE compatibility
mode emulates a traditional Parallel
ATA (IDE) based configuration by
reporting up to four SATA devices to the
user and the operating system as if they
were IDE / Parallel ATA devices. The
devices attached to SATA ports 0 and 2
are reported as IDE Primary channel
master and slave devices. The devices
attached to SATA ports 1 and 3 are
reported as IDE Secondary channel
master and slave devices.
AHCI: The Advanced Host Controller
Interface (AHCI) Option ROM identifies
and configures AHCI devices on all six
SATA ports.
Note: The AHCI Option ROM supports only
Hard Disk Drives and CD-ROM devices. Other
types of devices are not supported by the
AHCI Option ROM (i.e. tape drives). If the
connected device is not supported, an error
message is displayed informing the user that
the AHCI OPROM cannot handle this device,
and the device is not accessible in pre-OS.
Once the system boots to an OS, OS drivers
must be installed for these devices to be
functional during OS runtime.
SW RAID: The RAID for Serial ATA
Option ROM enumerates and configures
SATA devices as a Redundant Array of
Independent Disks (RAID). BIOS Setup
does not report device information for
any drives configured by the Option
ROM as part of a RAID volume.
