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

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.

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
Page 47
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
Page 48
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
Page 74
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

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

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.
