Intel Desktop Board DH77EB Technical Product Specification
26
The underlying SATA functionality is transparent to the operating system. The SATA
controller can operate in both legacy and native modes. In legacy mode, standard IDE
I/O and IRQ resources are assigned (IRQ 14 and 15). In native mode, standard PCI
Conventional bus resource steering is used. Native mode is the preferred mode for
configurations using the Windows* XP and Windows 7 operating systems.
NOTE
Many SATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.

Smart Response Technology is a disk caching solution that can provide improved
computer system performance with improved power savings. It allows configuration of
a computer system with the advantage of having HDDs for maximum storage capacity
with system performance at or near SSD performance levels.

NOTE
In order to use supported RAID and Intel Smart Response Technology features, you
must first enable RAID in the BIOS. Also, during Microsoft Windows XP installation, you
must press F6 to install the RAID drivers. See your Microsoft Windows XP
documentation for more information about installing drivers during installation.
Microsoft Windows 7 includes the necessary RAID drivers for both AHCI and RAID
without the need to install separate RAID drivers using the F6 switch in the operating
system installation process.
