1.11 LAN Subsystem (Optional)
The Network Interface Controller subsystem consists of the ICH4 (with integrated LAN Media
Access Controller) and a physical layer interface device. Features of the LAN subsystem include:
• PCI Bus Master interface
• CSMA/CD Protocol Engine
• Serial CSMA/CD unit interface that supports the 82562ET (10/100 Mbit/sec Ethernet) on the
Access Controller) and a physical layer interface device. Features of the LAN subsystem include:
• PCI Bus Master interface
• CSMA/CD Protocol Engine
• Serial CSMA/CD unit interface that supports the 82562ET (10/100 Mbit/sec Ethernet) on the
CNR bus
• PCI Power Management
Supports ACPI technology
