1.2General Description

The LBC-486/586Plus is a small, high-performance, embeddable computer system on a single

board. It integrates a number of popular I/O options including VGA, Ethernet, Solid-State Disk, and

High-Density Parallel I/O. Four PC compatible serial ports are standard, as are the floppy,hard disk,

andparallelprinterinterfaces.TheLBC-Plusispopulated with either a 100 MHz AMD DX4proc essor

or the AMD 5x85 133 MHz processor. Up to 32Mbytes of user installable SIMM memory is sup-

ported. An optional 256KB level two cache is also available. A full 16-bit PC/104 expansion bus is

provided for further expansion to an entire industry of add-on peripherals including sound and speech

modules,SCSIcontrollers,Analog I/O modules, and literally hundreds of other optionsava ilable from

WinSystems and a variety of vendors supporting the PC/104 standard. An onboard silicon disk array

supportsdisksupto2megabytesinsizeandcanutilize SRAM, PEROM or EPROM as the disk media .

Boot capability is provided onboard and a set of utilities and drivers are provided to makethe silicon

disk based system very user friendly. Alternately, the M-Systems DiskOnChip FLASH modules ma y

be populated, supporting disk sizes ranging from 1 Megabyte to 12 Megabytes.

2LBC-PLUS Technical Reference

2.1Introduction

Thissectionofthe manualisintended toprovidesufficientinformationregardingtheconfiguration

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

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

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

5PM Central Time.

2.2ALI 1487/1489 Chipset

The LBC-Plus utilizes the ALI FINALI-486 Chipset which provides a highly-integrated, high-

performancebackboneforfullPC/ATcompatibility.TheChipsetcontainsthelogicforDRAMandbus

state control as well as the standard complement of 'AT' class peripherals, including :

8 DMA Channels compatible with PC/AT 8237A DMA controllers

15 interrupt inputs compatible with master/slaved 8259 interrupt controllers

Three 8254 compatible timer/counter channels

A PC-AT compatible real time clock/calendar with CMOS RAM

A PCI BUS IDE interface

A PC/AT compatible keyboard interface

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

setup. Users desiringtoaccesstheseinternalperipherals directly should referto any manufacturersge-

neric literature on the equivalent discrete component.

There are a number of internal registers within the Finali-486 chipset that are used by the BIOSfor

control and configuration. Refer to the I/O map in Appendix A for port usage to avoid conf licts when

adding external I/O devices.

2.3CPU Speed Selection

The LBC-Plus uses a Crystal controlled frequency synthesizer to control the CPU clock rate. The

jumper block at J12 allows for the selection of any of 8 CPU base clock frequencies ranging f rom 8

MHz to 100 MHz.

The table below gives all of the possible CPU clock speeds available by jumpering J12.

NOTE : The LBC-Plus board will be jumpered at the factory for the rated speed of the installed

processor. Jumpering J12 to any speed in excess of the rated speed may result in CPU overhea ting,

misoperation, and possible destruction of the CPU. Failures of CPUs which have been operated above

their rated speed or temperature are not covered under the WinSystems standard product warranty.

2.3.1 Clock Multiplier Select

486DX4 and 5X86 processors actually run at a multiple of the base oscillator frequency. T he

jumper block at J36 allows selection of the multiplier as shown here :

2.4PCI Clock Select

The PCI bus clock source must be selected using jumper blocks at J14 and J31. The CPUCLK

source may be selected any time the CPU base frequency is less than or equal to 33MHz. For any CPU

base frequency in excess of 33MHz the CPUCLK/2 selection must be made.

2.5Memory Installation

The LBC-Plus utilizes user installable 72-pin standard SIMMs. SIMM modules should be a

minimum speed of 70nS and X32 architecture is preferred as there is no support for the paritybits pro-

vided by X36 bit modules. A single SIMM socket is provided which can support DRAM sizes from

1MB to 32MB.

Installation is accomplished with power off by angling the SIMM module approximately 30 de -

grees from vertical and inserting the fingers into the connector (It may be necessary to remove any de-

viceinstalledintheU27socket.).TheSIMMmoduleiskeyedslightlyoff-centerandcannotbeinserted

backwards without extreme force. Once the fingers are in the socket, the module is then rotated to the

vertical until the retaining clips snap into place. Removal is the reverse process. Pull th eretainingclips

outward and the SIMM module, once released, should rotate back to an appropriate removal angle.
