Features 1
The DP5 is a dual-PentiumÔ (3.3V) system board that utilizes the
PCI/IS architecture. It has two zero-insertion force (ZIF)-type CPU
sockets that accommodate Pentium CPUs. It also has three IS - T
slots, two PCI slots, one IS -/PCI-shared slot, and six 72-pin single
in-line memory module (SIMM) sockets that can accommodate a
maximum memory of 384 MB. The second-level cache is upgradable
to 512 KB.
Four Intel Neptune application-specific integrated circuit ( SIC)
chipsets, a SMC665 super I/O controller, a PC87410 enhanced local-
IDE controller, a IC-7870 SCSI chip and a single-chip Fast SCSI-2
host adapter are also incorporated in the motherboard to further
enhance system performance. The board also conforms to the EP
“green” standards.
The board measures 220 mm x 330 mm (full baby- T size).

Features
System Board Components
Microprocessor
The DP5 system board uses dual Pentium (P54C) processors running
at 50, 60 or 66 MHz (75/90/100 MHz core clock). Chapter 2 gives
details on how to upgrade the Pentium processor.
ASICs
The SICs onboard are the Intel Neptune 82434NX, 82433NX, and
82379 B. The 82434NX serves as the host/PCI bridge, DR M
controller and second-level cache controller. The 82433NX functions
as the local bus accelerator. The 82379 B acts as the IS /PCI bus
bridge that translates the PCI bus cycles into IS bus cycles or vice-
versa. It also functions as an IS arbiter, DM cycle and interrupt
controller.
Award BIOS
The ward BIOS (basic input-output system) resides in the flash ROM
chip. This contains the program that performs the power-on self-tests
(POST) upon booting. During POST, this program activates the
peripheral devices, tests onboard memory, and prepares the system
for operation. Chapter 3 gives more information on the ward BIOS.
1-4 User’s Guide

Features
Expansion Slots
The board expansion slots consist of three IS - T, two PCI and one
IS -/PCI-shared slots. These expansion slots are the parallel bars on
the system board. Each slot has rows of golden pins that serve as a
clutch to secure the contacts of expansion boards. Chapter 2 tells
how to install expansion boards.
DRAM Sockets
The system board has six 72-pin DR M sockets that expand system
memory to a maximum of 384 MB. These sockets accept single- and
double-sided SIMMs. Chapter 2 discusses the available memory
configurations.
Dual-channel PCI Mode 3 IDE
The board utilizes the enhanced integrated drive electronics (IDE)
interface that improves the data transfer rate. It also allows the
system to support four E-IDE mode 3 devices, including fixed disks
with more than 528-MB capacity. This feature offers users increased
data storage capacity.
User’s Guide 1-5

Features
Super I O Controller
The onboard super I/O controller chip supports two U RT
16450/16550-compatible serial ports and a parallel port (SPP, EPP,
ECP)1. It also accommodates 1.2-/1.44-/2.88-MB diskette drives
allowing full-range access to 5.25-inch drives with 360-KB or 1.2-MB
format and 3.5-inch drives with 720-KB, 1.44-MB or 2.88-MB format.
Keyboard Connector
The keyboard connector at the rear of the system board accepts any
T-compatible keyboard. PS/2 keyboard and mouse connectors are
optional.
SRAM
The system board supports 256-KB and 512-KB second-level, write-
back and write-through cache.

EPP: Enhanced Parallel Port (IEEE 1284 compliant)
ECP: Extended Capabilities Port (IEEE 1284 compliant)
1-6 User’s Guide

Features
SCSI Feature
The system board features a single-chip Fast SCSI-2 host adapter
that adds SCSI I/O capability to the system. The chipset consists of
all the components found on a SCSI host adapter such as an onboard
microcontroller, bus master interface controller and SCSI controllers,
and allows a full 20 MB/second burst transfer rate.
To use the feature, connect any SCSI device to the SCSI interface on
the system board. Enter the BIOS utility to set the PCI slot
parameters. See Chapter 3 for details on PCI configuration. Refer to
the SCSI manual or diskette for more information on using SCSI.
Power Management
The DP5 conforms to the power-saving standards of the U.S.
Environmental Protection gency (EP ) Energy Star program. The
system board features four system power-saving modes that reduce
power consumption. For more information on the power-saving
modes, see Chapter 3.

Chapter
Hardware Setup 2
This chapter discusses the CPU options, tells how to set jumpers,
upgrade system memory, add expansion boards, and install the
system board.
Install the CPU, memory, and set the jumpers before you install the
board into a housing. You may add the other components after
installing the board. ead this chapter to learn about the components
before you install them.
ESD Precautions
Electrostatic discharge (ESD) can damage your processor, disk
drives, expansion boards, and other components. Always observe
the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until
you are ready to install it.
2. Wear a wrist grounding strap and attach it to a metal part of the
system before handling components. If a wrist strap is not
available, maintain contact with a metal part of the system unit
throughout any procedure requiring ESD protection.
