486 EISA System Board

Read Me First

The E486-33/50IC and/or E486DX2-50IC system board requires the installation of the ECU (EISA Configuration Utility), which is found in the EISA Configuration Utility diskette provided with this system board.

The ECU configures the EISA devices and maintain system parameters by storing them in the Extended CMOS Memory, so that BIOS can initialize the system board and the expansion boards inserted in the EISA slots once you power up your system.

The Extended CMOS Memory uses 8Kx8 SRAM and is equipped with an internal battery that needs to be constantly charged. Due to the length of time spent on shipment and storage of these system boards, the internal battery might have drained and the information stored in the Extended CMOS Memory may be lost. If you power up your system, the message "EISA CMOS Inoperational" may appear. If this happens, simply run the ECU software, bundled with the system board, to reconfigure the system. Save the configuration and reboot your system. Refer to the EISA Configuration Utility section on page 4-1 for more information.

Installation Overview

❖❖

This chapter summarizes the steps in installing your E486-33/50IC and/or E486DX2-50IC system board into your system unit. It also includes a description of the area in which you must work in. Before installing the system board, determine first the size of the memory you need onboard. Please refer to the memory chart on pages 2-4 and 2-5 for the memory size and type of SIM modules needed.

Preparing the Area

Before unpacking the system board, make sure the location you have selected will provide a relatively dust and static free environment. Excessive exposure to dust, static electricity, direct sunlight, excessive humidity, extreme cold and water can damage the operational capabilities of your system board. Avoid soft surfaces such as beds and carpeted floors which can hinder air circulation. These areas also attract static electricity which can damage some circuits on your system board.

Be sure that the power source has a properly grounded, three-pronged socket. It is essential that the power connection be properly grounded for correct functioning of your system board. For further protection, the use of a surge protection socket is recommended. This will protect the system board from damage that may result from a power surge on the line.

Move items that generate magnetic fields away from your system board, since magnetic fields can also damage your system board. Once you have selected the

ideal location, unpack the E486-33/50IC and/or E486DX2-50IC system board carefully.

Handling the System Board

It is quite easy to inadvertently damage your system board even before installing it to your system unit. Static electrical discharge can damage your system board even though there are no signs of physical damage. Extra care must be taken in handling the system board to make sure that no static build-up is present.

Tips in Handling the System Board

1) To prevent electrostatic build-up, you should leave the board in its anti-static bag until you are ready to install it.

2) Hold the system board by its edges only. Be careful not to touch any of the components, contacts or connections on the board.

E486DX EISA

3) Avoid touching the pins on all modules and connectors. Hold modules and connectors by their ends.

Hardware Installation

Computer components are easily damaged by static electricity. Be careful to handle the system board by its edges. Do not touch any part of its circuitry, especially the gold contacts, with your hands. Do all the preparation work on a static-free surface. Place the system board on a static-free table with the components facing up.

Memory Installation

The E486-33/50IC and/or E486DX2-50IC system board can support 1MB to 64MB of memory using SIMMs. Four banks are available to be installed with 256Kx9, 1Mx9, or 4Mx9 SIM modules. Each bank consists of four SIMM sockets. The SIM modules are plug into the banks at the upper left side of the board.

SIMM is an acronym for Single In-line Memory Module. A SIMM consists of several RAM chips soldered onto a small circuit board. A SIMM connects with the system board via a 30-pin card-edge connector.

You will need 4 to 16 pieces of SIM modules depending on the amount of memory you intend to install. Your system board can be configured with 1MB, 2MB, 3MB, 4MB, 5MB, 6MB, 7MB, 8MB, 9MB, 10MB, 12MB, 13MB, 16MB, 17MB, 18MB, 19MB, 20MB, 21MB, 22MB, 24MB, 25MB, 28MB, 32MB, 33MB, 34MB, 36MB, 37MB, 40MB, 48MB, 49MB, 52MB, or 64MB of memory onboard.

EISA Configuration Utility

Overview

The E486-33/50IC and/or E486DX2-50IC system board requires the installation of the EISA Configuration Utility (ECU) which is used to configure EISA (Extended Industry Standard Architecture) computer systems.

EISA system boards and EISA adapter cards are much more complex than the designs of the ISA (Industry Standard Architecture), making the setup of jumpers and switches more complicated. ECU was created to automate this configuration process.

The CFG files that come with each EISA expansion board must be copied onto the EISA Configuration Utility diskette. ECU will then store this configuration data in the system's Extended CMOS Memory. The CFG file tells the EISA Configuration Utility what choices the user has in configuring the card and what system resources have to be reserved for the card.

E486DX EISA

File Structure

The files used by the EISA Configuration Utility are as follows:

CFG Files

Each EISA expansion board comes with a CFG file. A board's CFG file contains detailed information about the board as well as the functions that the board can perform.

EISA Configuration Utility

◆◆

◆ 4-1

◆◆

Page 36

486 EISA System Board

Duplicate Files

ECU allows you to copy an existing CFG file to a different filename or directory. If the file is copied into a directory where a file by the same name already exists, the new file will be renamed, using the same filename but with a number 1 before the filename. If the same file is copied into that directory again, it will be renamed again using the same filename, this time preceded by the number 2; and so on. This procedure prevents the loss of any CFG file.

CFGLIST File

The CFGLIST file is a text file that contains the names of the CFG files to be configured. Use the CFGLIST file when you do not want to select the CFG files individually each time you create a configuration.

CMS File

The CMS file contains a copy of the configuration information that is written into the system's Extended CMOS Memory. Each CMS file should have a corresponding INF file.

INF File

The INF file contains detailed information about a configuration such as switch and jumper settings, software statements, connection statements, and resource allocation. The INF file is used by the "Display/Print" command to recall information on a saved configuration. Each INF file should have a corresponding CMS file.

◆ ◆

Page 37

Initial Configuration

Prior to installing the EISA Configuration Utility, you must have the CFG files for the expansion boards and system board you are planning to install available. To install:

1. Create a directory on the disk drive you want the EISA Configuration Utility to be installed on.

2. Change into the directory you have just created.

3. Insert the EISA Configuration Utility diskette into drive a: and copy the files into the current

directory.

4. To run the EISA Configuration Utility, access the EISA subdirectory you have created and type,

CFG <Enter>.

Menu Options

E486DX EISA

The EISA Configuration Utility allows you to copy or backup configuration files, configure an EISA system automatically or manually, and display or print information related to a configuration that has been previously saved. The utility also includes an online Help menu which may be accessed anytime by pressing the <F1> key.

Use the arrow keys to move to the menu or option of your choice, then press <Enter>. You may also select an option by pressing the key corresponding to the highlighted letter of the option. If you are using a mouse, move the mouse pointer to the selected option and click the left-mouse button once.

DEMM 386 Software Driver

❖❖

DEMM 386 is a software driver that is used on the E486-33/50IC and/or E486DX2-50IC system board to translate extended memory into expanded memory. Copy the DEMM386.SYS driver from the diskette provided into your root directory. After copying the driver, add this line to your CONFIG.SYS file:

Device = DEMM386.SYS [/B=xxxx] [/H=yy] [/S=zz] [/T=tttt]

[/X=aaaa-bbbb] [/I=cccc-dddd] [/L]

Note:

This line should be placed before any other drivers that use extended memory.

xxxx is the EMS page frame base address in

hexadecimal. In expanded memory management, a contiguous 64KB page frame segment must be reserved. The following are valid page frame addresses; C000, C400, C800, CC00, D000, D400, D800, DC00 and E000. The default page frame address is E000.

E486DX EISA

yy is the maximum handle numbers (in

hexadecimal) to be reserved. The default value is 40H (64 in decimal).

zz is the maximum number of contexts (in

hexadecimal) to be reserved. The default value is 40H (64 in decimal).

tttt specifies an area of the extended memory (in

kilobytes) to be reserved and should not be used by the EMS driver. Without the /T option, all

DEMM386 Software Driver

◆ 5-1

of the extended memory will be used as expanded memory.

aaaa-bbbb specifies that a certain range of memory

should be excluded from EMS mapping. aaaa is the starting segment address and bbbb is the ending segment address of the range. For example, if there is a network adapter in your system that occupies memory from D000 to D3FF, specify /X=D000-D3FF to exclude this range from EMS mapping.

cccc-dddd specifies that a certain range of memory

should be included in EMS mapping. cccc is the starting segment address and dddd is the

ending segment address of the range. This

option is very useful if you want the EMS driver to utilize unused video area. For example, if a Hercules graphics adapter is installed in your system, the memory range between A000 to AFFF is not used at all. By specifying /I=A000-AFFF, the EMS driver will utilize the area for EMS mapping.

/L specifies that the backfill area (384KB from

4000:0 to 9000:FFFF) will be used exclusively as conventional memory. The EMS driver will not be able to use this area as page frames or EMS pages.

Note:

All the parameters are optional and need only to be added in certain instances, depending on your application.

Troubleshooting Checklist

❖❖

If you experience difficulty with the E486-33/50IC and/ or E486DX2-50IC system board, please refer to the checklist below. If you still cannot isolate the problem, please contact your dealer.

1) Check the jumper settings to ensure that the jumpers are properly set. If in doubt, refer to the “Board

Configuration” section.

2) Verify that all SIM modules are seated securely into the bank sockets.

3) Make sure that the SIM modules are in the correct location.

4) Check that all populated memory banks are completely filled. If not, fill them completely.

5) If your board fails to function, place the board on a flat surface and seat all socketed components (gently press each component into the socket).

The E486-33/50IC and/or E486DX2-50IC system board uses the 82358 EISA Bus Controller that supports the following:

• Provides EISA/ISA bus cycle compatibility

• Interfaces host (CPU) bus to EISA/ISA bus

• Translates host bus cycles to EISA/ISA bus cycles

• Generates ISA signals for EISA masters

• Generates EISA signals for ISA masters

• Supports 8-, 16-, or 32-bit DMA cycles

• Supports host and EISA/ISA refresh cycles

• Generates control signals for address and data buffers

• Supports byte assembly/disassembly for 8-, 16-, or 32bit data transfers

• Supports I/O recovery mechanism
