3.4.2.3 On-Board LAN
The development board has one RJ-45 interface – at connector J5A1 - through which
10/100/1000 ethernet is available. The ethernet MAC is located in the ICH8-M and the
PHY is located externally in the 82566MM LAN Connect Interface (LCI) device. The
82566MM is connected to the ICH8-M via two interfaces: LCI for 10/100 Mbps traffic
and GLCI (Gigabit LCI) for 1000Mbps traffic. Intel

Active Management Technology is
optionally supported through these components.

Note: Further details on the location of the RJ-45 interface can be found in Section
4.2.
3.4.2.4 High Definition Audio
Intel
®
High Definition Audio is not supported on the development board.
3.4.2.5 ATA/ Storage
The development board has one parallel ATA IDE connector and three serial ATA
connectors.
The parallel ATA IDE Connector is a standard 40-pin connector at J7J4. This connector
supports up to two Ultra ATA/100 hard drives; one master and one slave.
There are three SATA connectors on the development board – one ‘Direct Connect’
connector and two ‘Cable Connect’ connectors. The ‘Direct Connect’ connector, located
at J8J1, provides both signaling and power while the ‘Cable Connect’ connectors,
located at J7H1 and J7J3, only provides signals (the user typically uses an ATX power
supply for the drive power). A green LED at location CR6J1 indicates activity on the
ATA channel.
The development board also supports ‘ATA swap’ capability for both the parallel IDE
channel and the serial ATA channels. A device can be powered down by software and
the port can then be disabled, allowing removal and insertion of a new device. The
parallel IDE device should be powered from the power connector, J4J2, on the
development board to utilize the hot swap feature. This feature requires customer-
developed software support.
Note: Desktop hard drives must be powered using the external ATX power supply, not the
onboard power supply.

3.4.2.6 USB Connectors
The ICH8-M provides a total of ten USB 2.0 ports. Three ports are routed to a triple-
stack USB connector at J3A1. Two ports are routed to a combination RJ-45/dual USB
