Introduction

TheEP-5BTXA-Emainboardisahighperformancesystemhardware

based on Intel Pentium processor and is equipped with three PCI slots, three

standard ISA slots, a PnP Super I/O controller and two dual-port PCI-IDE

connectors for the future expansion. The hardware dimension is an AT form-

factorthatis220mmx200mmwithafour-layerdesigntechnology.

Specification

Intel82430TXPCIsetchipset.

Intel Pentium Processor operating at90 ~333 MHz (Easy CPU CLK

Setting JP3 : One Jumper Only) and P55C with321 ZIF socket7for

scalability to accept faster processors in the future.

Supports an onboard Switching Voltage Regulator to increase CPU and

System'sreliability.

SupportsCPUVcoreVoltage2.0V/12.1V/2.8V/2.9V/3.2Vselection.

Supports up to 256 MegaBytes of DRAM(a minimum of 8 MB) on board

(168-PinDIMMx2),BIOSautoEDODRAMandSDRAM

configuration.(RefertoChapter 2-4SystemMemoryConfiguration)

Supports Onboard Burst/Pipelined burst synchronous L2 Write Back

Cache.Thecachememoryis512KB(64KB*64SRAM).

Supports three 16-bit ISA slots and three 32-bit PCI slots and provides two

independent high performance PCI IDE interfaces capable of supporting PIO

Mode3andMode4devices.

Supports ATAPI(e.g.CD-ROM)devices and UltraDMA33forbothIDE

interface.

Supports 1 floppy port, 1 parallel port (EPP,ECP port), and 2 serial ports

(16550FastUARTcompatible)withPnPSuperI/Ochip.

Supports both PS/2 style mouse Header and AT keyboard connector

Supports Award Plug & Play BIOS . The BIOS is stored in Flash EPROM

form. It provides better upgradeability for the system.

Supports a CPU Hardware sleep and SMM (System Management Mode)

function.

Supports a USB header

2-1 Overview

TheEP-5BTXA-EisdesignedwithIntel82430TXPCIsetchipsetwhichis

developed by INTEL Corporation to fully support Pentium Processor PCI/ISA

system.TheIntel82430TXPCIsetchipsetcanincreaseintegrationandimprove

performance designs. The chipset provides an integrated IDE controller with two high

performanceIDE interfaces for up to fourIDEdevices(harddevices, CD-ROM device,

etc). The PnP Super I/O controller provides the standard PC I/O functions: a floppy

interface,two16ByteFIFOserialportsandanEPP/ECPcapableparallelport.The EP-

5BTXA-Elayout is shown in the onet page for user's reference. Caremust be taken

wheninsertingmemorymodules,insertingCPUorevenpluggingPCI card into the

associated slots to avoid damaging any circuits or sockets on board. A cooling fan is

stronglyrecommendedwheninstalling P54C/P54CTB/P55C(MMX)/K5/K6/6x86

(6x86L) processor due to possible overheat.

TheEP-5BTXA-Esupportsaminimumof8MBofSystemMemoryandamaxi-

mum of 256MB with 512KB synchronous SRAM Onboard to increase system

performance.

The EP-5BTXA-Esupports synchronous DRAM.TheEP-5BTXA-E

provides two 168-pin DIMM sites for memory expansion. Each socket supports 8MB,

16MB,32MB,64MBand128MBDIMMsingle-sidedordouble-sidedmemory

modules.Thememorytimingrequires83MHz(12ns),100MHz(10ns)forSDRAM.This

mainboard has two 168-pin DIMM sites to support 3.3V (power level) Unbuffered

SynchronousDRAMs(SDRAM).Memoryparitygenerationandcheckingarenot

supported.

TheEP-5BTXA-E supportstwoOnboardPCIIDEconnectorsthatcansupport

PIO Mode/Ultra DMA 33 device and detect IDE harddisk type by BIOS utility

automatically.

The EP-5BTXA-EsupportsAward Plug & PlayBIOSfor the ISA andPCIcards.

The BIOS can be located in Flash EPROM. The advantage of having Flash EPROM is

much easier to replace BIOS code if necessary.

The EP-5BTXA-Ehas been designed with AT form-factor power connector. The
