2EBC-BX Technical Reference

2.1 Introduction

Thissectionofthemanualisintendedtoprovidesufficientinformationregardingtheconfiguration

and usage of the EBC-BX board. WinSystems maintains a Technical Support group to help ans wer

questions regarding configuration, usage, or programming of the board. For answers to questions not

adequately addressed in this manual, contact Technical Support at (817) 274-7553 between 8AM and

5PM Central Time.

2.2 Intel FW82443BX / SMSC Victory-66 Chipset

The EBC-BX utilizes the Intel FW82443BX North bridge coupled with the SMSC Victory-66

Southbridge.Thiscombinedchipset providesahighly-integrated,high-performancebackbonefor full

Pentiumclass compatibility. TheChipsetcontainsthelogicforDRAMandbusstatecontrolas well as

the standard complement of 'AT' class peripherals, including :

Two-82C37 DMA controllers

Two-82C59 Interrupt controllers

82C54 Timer/Counter

Real Time Clock

Enhanced Power Management

Full Plug and Play compatibility

These functional units are 100% PC/AT compatible and are supported by the Award BIOS and

setup. Usersdesiringtoaccesstheseinternalperipheralsdirectlyshouldrefertoanymanufacturersge-

neric literature on the equivalent discrete component.

Thereare a numberofinternal registers within theBXchipset that areusedby theBIOSfor control

andconfiguration.RefertotheI/OmapinAppendixAforportusagetoavoidconflictswhenaddingex-

ternal I/O devices.

2.3 Memory Installation

TheEBC-BXsupportsasingleuserinstallable168-pinstandardDIMM.DIMMmodulesshouldbe

a minimum speed of PC-100 and x64 or x 72. Either ECC on non-ECC parts may be used. A single

DIMM socket is pro videdwhich can supportSDRAMsizes from32MBto256MB.Foralistofquali-

fied DIMMs, go to http://www.winsystems.com/memory

Installation is accomplished with power off by inserting the DIMM module directly into the con-

nector at M1. The DIMM module is keyed in 2 places and cannot be inserted backwards without ex-

030923 OPERATIONS MANUAL EBC-BX Page 2- 1

treme force. The module is inserted until the retaining clips snap into place. Removal is the reverse

process. Push down on the retaining clips, moving them outward. The DIMM module, once released,

will be forced up to an appropriate removal position.

2.4 Interrupt Routing

AllinterruptsontheEBC-BX areroutedtotheirrespectivePC/104buspins.Onboardnon-PnP pe-

ripherals, are routed to their typical usage interrupts using the jumper block at J19. This block allows

disconnecting or rerouting of the onboard interrupts. The layout for the J19 header and the default

jumper settings are shown below.

2.5 Power/Reset Connections

Power is applied to the EBC-BX via the connector at J3 (Molex part number 26-60-7091). The pin

definitions for J3 are given below. An optional push-button-reset (Normally Open) may also be routed

into J3 if desired. Momentary closure to ground forces a hardware reset.

Note : The 3.3 Volt input pin does not provide power to any devices on the board. It is routed di-

rectlytothePC/104PlusBusandisonlyrequirediftherearePC/104Pluscardsthat require3.3 Voltsbe

suppliedfromtheBus.The+12and-12VoltpinsarerouteddirectlytothePC/104connectorsand flat-

panel connectors and are not required for normal board operation.

2.6 Mouse Interface

A PS/2 mouse may be attached via the connector at J1. An adapter cable, CBL-225-1 is available

fromWinSystemstoadapttoaconventionalPS/2mouseconnector.ThepinoutforJ1isshownhere.
