Read Me First

The EB3486-TN system board requires the installation of the
ECU (EISA Configuration Utility), found on the provided EISA
Configuration Utility diskette, for proper operation of this
system board.

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

The Extended CMOS Memory is equipped with an internal
battery that needs to be constantly charged. In a small number
of cases, the internal battery may have drained and the
information stored in the Extended CMOS Memory lost during
shipment. If this happens, you will get the message "EISA
CMOS Inoperational" when you power up your system. 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 6-1 for more detailed information.

v Introduction

The EB3486-TN is a revolutionary station board based
on our own Processor Upgradeable Microcomputer
Architecture (PUMA) platform. It's unique design
allows you to use either a 486SX, 486DX or 486DX2
CPU at any speed on the station board. This is accom­plished by installing the CPU on a CPU module that
plugs directly into the station board, thus making it easy
and affordable to upgrade.

The EB3486-TN station board is equipped with one
VESA compliant local bus slot for use with local bus
video or network cards. Any future VESA local-bus
products will also work. In addition to the VESA local
bus slot, the station board also has eight 32-bit EISA
(Extended Industry Standard Architecture) expansion
slots and one CPU module slot.

EISA extends the operational capabilities of the ISA
(Industry Standard Architecture) standard while main­taining compatibility with ISA expansion boards. The
EISA Configuration Utility (ECU) must be installed and
run to configure the board and the EISA expansion
boards that will be inserted in the EISA expansion slots.

EB3486-TN

If you have a DBII-486CSX or DBII-486CDX/DX2
CPU module, the system will consist of two levels of
cache memory for fast local access of frequently ac­cessed code and data. The first level, or internal cache,
is built-in to the CPU with 8KB of cache memory. The
second level, or external cache, can support 32KB/64KB
of cache memory using 8Kx8 (25ns) SRAMs or 128KB/
256KB of
cache memory using 32Kx8 (25ns) SRAMs. The
DBII-486SX or DBII-486DX/DX2 CPU modules only

support internal cache.
The EB3486-TN station board uses 256Kx36, 512Kx36,
1Mx36, 2Mx36, 4Mx36, 8Mx36, 16Mx36 and 32Mx36
SIM modules with speeds of 70ns or 80ns. It can hold
128MB of memory onboard configurable in 30 different
sizes.

System support functions include system BIOS and
VGA BIOS Shadow RAM support, memory remapping,
seven channels of Direct Memory Access, 14 levels of
interrupts and five programmable timers.

PUMA Station Board

v Installation Overview

This chapter summarizes the steps in installing your
EB3486-TN system board into your system unit. It also
includes a description of the area in which you must
work. Before installing the system board, determine the
size of memory you need onboard. Please refer to the
memory chart on page 3-3 and 3-4 for the memory size,
type and quantity of SIM modules needed.

Preparing the Area

Before unpacking the system board, make sure the
location you have selected provides a relatively dust- and
static-free environment. Excessive exposure to dust,
static electricity, direct sunlight, excessive humidity,
extreme cold or water can damage your system board or
greatly reduce its operational abilities.

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. Use a surge protector to shield
the system from damage that may result from a power
surge on the line.

Air circulating around the system unit cools your system.
Please ensure adequate air circulation around the entire
unit and do not block the fan vent on the back of the
unit.

Once you have selected the ideal location, unpack the
EB3486-TN system board carefully.

2-1 u Installation Overview

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. The
damage may show up as a malfunction when you try to
operate the machine, or it may result in premature
failure. Take due care 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, leave the board in
its anti-static bag until you are ready to install it.

2) To ground yourself, place your hand on any bare

metal part of the system chassis.

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

v Hardware Installation

Computer components are easily damaged by static
electricity. Static electrical discharge can damage your
system board, even though there are no signs of physical
damage. Be careful to handle the system board by its
edges. Do not touch any part of the 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 EB3486-TN system board can support 1MB to
128MB of memory using HSIMMs. HSIMM is an
acronym for High Density Single In-line Memory Mod­ule. A HSIMM consists of several RAM chips soldered
onto a small circuit board. A HSIMM connects with the
system board via a 72-pin card-edge connector.

The HSIMM sockets are divided into four banks which
are located on the main board. The SIM modules are
plug into the banks at the upper-left side of the station
board.

You will need 1 to 4 pieces of HSIM modules, depend­ing on the amount of memory you intend to install.
Your system board can be configured to 1MB, 2MB,
3MB, 4MB, 6MB, 8MB, 9MB, 10MB, 11MB, 12MB,
14MB, 16MB, 20MB, 24MB, 28MB, 32MB, 36MB,
40MB, 44MB, 48MB, 56MB, 64MB, 68MB, 72MB,
80MB, 96MB, 100MB, 104MB, 112MB or 128MB of
onboard memory.

v EISA Configuration Utility

Overview

The EB3486-TN system board requires the use of the
EISA Configuration Utility (ECU). The ECU 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 ISA (Industry Stan­dard Architecture) boards and adapter cards, making the
setup of jumpers and switches more complicated. The
ECU was created to automate this configuration process.

The CFG files that come with each EISA expansion
board are copied onto the ECU diskette. The ECU then
stores this configuration data in the system's Extended
CMOS Memory. The CFG file tells the ECU what
choices the user has in configuring the card and what
system resources to reserve for the card. The
EB3486-TN system board uses the "DFI0300.CFG" file.

File Structure

The ECU uses three different files: the CFG, CMS and
INF files.

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 the board can perform.
For the EB3486-TN system board, choose the

"DFI0300.CFG" file to be configured.

6-1 u EISA Configuration Utility

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.

Initial Configuration

Every EISA system board and expansion board comes
with a CFG file. Prior to running the ECU, make sure
that all CFG files for expansion boards you are using are
in the same directory as the ECU file. If you did not
receive the CFG file for your expansion board, please
contact your dealer or the board manufacturer.

EB3486-TN

If you are installing an EISA hard drive controller/SCSI
host adapter, you will need to run the ECU from a
bootable floppy diskette because the system will not see
the hard drive until the EISA expansion board is
configured. To run the ECU after the hard drive
controller/SCSI host adapter is installed:

1. Create a directory on the disk drive where you want
to install the EISA configuration files. Change to
this directory.

EISA Configuration Utility u 6-2

PUMA Station Board

2. Copy your EISA Configuration Utility diskette and
the CFG files for all of your EISA boards to
this directory.

3. To run the ECU, make sure that you are in the
directory created in step 1 and type CFG.

Main Menu

The ECU outlines the six steps that involved in configur­ing a EISA system, steps 1, 2, 3 and 5 are optional. To
select a step, use the arrow keys to move to a step of
your choice and press <Enter>. You may also select a
step by pressing its number. If you are using a mouse,
move the mouse pointer to the selected option and click
the left-mouse button once.

Note:

For a mouse to work in the ECU, you must have a
previously installed mouse driver.

The utility also includes an online Help menu which may
be accessed anytime by pressing the <F1> key.

v DEMM 386 Software Driver

DEMM 386 is a software driver that is used on the
EB3486-TN system board to translate extended memory
into expanded memory.

Copy the DEMM386.SYS driver from the provided
diskette into your root directory. After copying the
driver, add a line to your CONFIG.SYS file using the
following syntax:

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. The parameters enclosed in
brackets "[" and "]" are optional and do not need to be
included. Do not include the "[" and "]" when typing
any parameters.

EB3486-TN

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.

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

DEMM 386 Software Driver u 7-1

PUMA Station Board

40H (64 in decimal).

tttt specifies an area of the extended memory (in

kilobytes) to be reserved that will not be used by
the EMS driver. Without the /T option, all 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 a network adapter in your system
occupies memory from D0000 to D3FFF, 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 A0000 to AFFFF 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.

v Troubleshooting Checklist

If you experience difficulty with the EB3486-TN 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).

System Interrupts

A NMI is an interrupt requiring immediate attention and
has priority over the normal interrupt lines (IRQX).
NMI interrupts are caused by the following conditions:

Interrupt Controller 1 Interrupt Controller 2

IRQ0-Timer Output 0 (Out 0) IRQ8-Realtime Clock INT
IRQ1-Keyboard (Output Buffer Full) IRQ9-Software Redirected

IRQ3-Serial Port 2 IRQ10-Reserved
IRQ4-Serial Port 1 IRQ11-Reserved
IRQ5-Parallel Port 2 IRQ12-Reserved
IRQ6-Diskette Controller IRQ14-Fixed Disk Controller
IRQ7-Parallel Port 1 IRQ15-Reserved

NMI Source

to INT 0AH (IRQ2)

Note:

Any or all interrupts including NMI may be masked.
The 14 levels of system interrupts from high to low are
ordered as: IRQ0>IRQ1>IRQ8>IRQ9>IRQ10>IRQ11
>IRQ12>IRQ14>IRQ15>IRQ3>IRQ4>IRQ5
>IRQ6>IRQ7.

Burst Cycles

The 486 microprocessor accepts burst cycles for any bus
request that requires more than one data cycle. During
burst cycles, a new data item is strobed into the 486
microprocessor for every clock rather than every other
clock as in non-burst cycles.

TACT84543 EISA Bus Control Unit

The EB3486-TN 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

E-5 u Appendix E

Extended CMOS Memory DS1387

The EB3486-TN system board has Extended CMOS
Memory installed onboard. Configuration information is
stored in the Extended CMOS Memory so the BIOS can
initialize the system board and the expansion boards
inserted in the EISA slots every time you power up your
system.

The Extended CMOS Memory uses a 4Kx8 SRAM
which is equipped with an internal battery. If the battery
runs down, the information stored in CMOS memory
may be lost. If this happens you must either reconfigure
the system or copy the backup configuration file into the
Extended CMOS Memory.
