Speaker

A 47 Ω inductive speaker is mounted on the motherboard. The speaker provides audible error code (beep code) information during the power-on self test (POST).

LAN Subsystem (Optional)

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

∙Shared memory structure in the host memory that copies data directly to/from host memory

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

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

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

Intel® 82559 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:

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

⎯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

⎯802.3µ 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 APM

⎯Support for Wake on LAN technology

⎯Support for ACPI D3 state
