Intel Desktop Board D815EEA Product Guide

PCI Enhanced IDE Interface

The PCI enhanced 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)

•PIO Mode 3 and PIO Mode 4 devices

•Ultra ATA/33, Ultra ATA/66, and Ultra ATA/100 protocols

•Support for laser servo (LS-120) drives

Expansion Slots

The desktop board has seven add-in board connectors: five PCI expansion slots, one AGP universal connector, and one CNR connector. The seven connectors support only six expansion cards because the CNR slot and PCI slot 5 are shared and cannot be used simultaneously.

Accelerated Graphics Port (AGP)

The AGP is a high-performance interface for graphics-intensive applications such as 3D graphics. AGP is independent of the PCI bus and is intended for use with graphical display devices. The AGP universal connector supports AGP 1X, 2X, and 4X. The AGP universal connector also supports GPA and DVI add-in cards.

An AGP card retention mechanism (RM) is included with the boxed desktop board. Installation instructions are presented in Chapter 2.

Audio Subsystem (Optional)

The board offers two AC ’97 V 1.03 compliant audio subsystems. Both audio subsystems include these features:

•Split digital/analog architecture for improved S/N (signal-to-noise) ratio: ≥ 85dB

•Power management support for APM 1.2 and ACPI 1.0 (driver dependent)

•3-D stereo enhancement

Basic Audio Subsystem (Optional)

The basic audio subsystem consists of the following:

•Intel 82801BA I/O Controller Hub (ICH2)

•Analog Devices AD1885 analog codec
