Intel Desktop Board D815EEA Product Guide

•Setting a user password restricts who can boot the computer. The password prompt is displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, you can enter either password to boot the computer.

Diagnostic LEDs

Four dual-colored diagnostic LEDs are located on the back panel. The LEDs report POST failures. See page 74 for information about the LEDs.

Speaker

A 47 Ω inductive speaker is mounted on the desktop board. The speaker provides audible error code (beep code) information during the Power-On Self-Test (POST).

LAN Subsystem

The Intel 82562ET (in conjunction with the Intel 82801BA ICH2) provides a Fast Ethernet Wired for Management (WfM) PCI LAN subsystem providing 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 802.3u Auto-Negotiation for the fastest available connection

•Jumperless configuration; the LAN subsystem is completely software configurable

Intel® 82562ET Platform LAN Connect Device (Optional)
