Intel Desktop Board D845PEMY Product Guide

LAN Subsystem

The Intel 82562ET (with the Intel 82801DB ICH4) provides a Fast PCI LAN subsystem providing both 10Base-T and 100Base-TX connectivity. The Intel 82562ET provides the following functions:

Basic 10/100 Ethernet LAN connectivity

Support for RJ-45 connector with status indicator LEDs

Programmable transit threshold

Configurable EEPROM that contains the MAC address

LAN Subsystem Software

For LAN software and drivers, refer to the D845PEMY link on Intel’s World Wide Web site at:

Enhanced IDE Interface

The ICH4’s IDE interface handles the exchange of information between the processor and peripheral devices like hard disks, CD-ROM drives, and Iomega Zip* drives inside the computer. The interface supports:

Up to four IDE devices (such as hard drives)

ATAPI devices (such as CD-ROM drives)

Older PIO Mode devices

Ultra DMA-33 and ATA-66/100 protocols

Laser Servo (LS-120) drives

Expansion Slots

Desktop Board D845PEMY has three PCI bus add-in card connectors.
