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.

EB3486-TN

Introduction u 1-1

vIntroduction

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 accom-

plished 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 main-

taining 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.

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 ac-

cessed 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.

vInstallation 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.
