Product Description

1.12 LAN Subsystem

The Intel 82559 Fast Ethernet Wired for Management (WfM) PCI LAN subsystem provides both 10Base-T and 100Base-TX connectivity. Features include:

∙32-bit, 33 MHz direct bus mastering on the PCI bus

∙10Base-T and 100Base-TX capability using a single RJ-45 connector with connection and activity status LEDs

∙IEEE 802.3u Auto-Negotiation for the fastest available connection

∙Jumperless configuration; the LAN subsystem is completely software-configurable

1.12.1Intel®82559 PCI LAN Controller

The Intel 82559 PCI LAN controller’s features include:

∙CSMA/CD Protocol Engine

∙PCI bus interface

∙DMA engine for movement of commands, status, and network data across the PCI bus

∙Integrated physical layer interface, including:

⎯Complete functionality necessary for the 10Base-T and 100Base-TX network interfaces; when in 10 Mbit/sec mode, the interface drives the cable directly

⎯A complete set of Media Independent Interface (MII) management registers for control and status reporting

⎯IEEE 802.3u Auto-Negotiation for automatically establishing the best operating mode when connected to other 10Base-T or 100Base-TX devices, whether half- or full-duplex capable

∙Integrated power management features, including support for wake on network event (from an ACPI S3 state using the PCI bus PME# signal)
