SATA Support

Intel Desktop Board DZ68DB provides two onboard 6.0 Gb/s Serial ATA (SATA)
channels and two onboard 3.0 Gb/s SATA channels.
The board also provides two 3.0 Gb/s external SATA (eSATA) channels (one via an
onboard connector and the other via a back panel connector).

Expandability

Intel Desktop Board DZ68DB provides the following connectors for system expansion:
• One PCI Express 2.0 x16 connector
• Two PCI Express 2.0 x1 connectors
• Three Conventional PCI bus connectors

Legacy I/O

The board's Legacy I/O Controller provides the following legacy features:
• Low pin count (LPC) interface
• Consumer Infrared (CIR) support
• Serial IRQ interface compatible with serialized IRQ support for Conventional PCI
bus systems
• Intelligent power management, including a programmable wake-up event interface
The BIOS Setup program provides configuration options for the Legacy I/O controller.

BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 61.

SATA Auto Configuration

If you install a SATA device (such as a hard drive) in your computer, the auto-
configuration utility in the BIOS automatically detects and configures the device for
your computer. You do not need to run the BIOS Setup program after installing a
SATA device. You can override the auto-configuration options by specifying manual
configuration in the BIOS Setup program.
The BIOS sets SATA to ACHI mode by default.
