WS440BX Motherboard Technical Product Specification
?
1.7.1 Intel 82558 LAN Controller
The Intel 82558 LAN controller provides the following functions:
? CSMA/CD Protocol Engine
? PCI bus interface (Rev 2.1 compliant)
? DMA engine for movement of commands, status, and network data across the PCI bus
? Integrated physical layer interface, including:
3 Complete functionality necessary for the 10Base-T and 100Base-TX interfaces; when in
10 Mbit/sec mode, the interface drives the cable directly
3 A complete set of MII management registers for control and status reporting
3 802.3? Auto-Negotiation for automatically establishing the best operating mode when
connected to other 10Base-T or 100Base-TX devices
? Integrated power management features, including:
3 Support for ACPI
3 Support for Wake on LAN technology
3 Support for Alert on LAN technology
? Digitally controlled adaptive equalizations and transmission
1.7.2 LAN Subsystem Software
The Intel EtherExpress PRO/100 WfM PCI LAN software provided includes setup/diagnostic
software (SETUP.EXE), and a readme file viewer (README.EXE). The LAN software is
available from Intel?s World Wide Web site (see Section 6.1).
1.7.3 Alert on LAN Component (Optional)
The Alert on LAN component is a companion device to the Intel 82558 LAN controller. Together,
these devices provide a management interface between a remote management console (or
management server) and client system monitoring instrumentation. When an alert input is
asserted, the Alert on LAN component transmits Ethernet packets to the 82558 through an 8-bit
dedicated data path. Examples of events that can trigger alert messages to a management server
include:
? Chassis intrusion
? System BIOS hang (transmits a POST error code)
? LAN leash (transmits an alert that the LAN cable was disconnected)
Information on the Alert on LAN component and its network management capabilities are
available from Intel?s World Wide Web site (see Section 6.1).
