2. Board Installation.

2.1 Unpacking

The mainboard package should contain the following
* The S1462 Mainboard
* User's Manual
* ECU User's Manual
* EISA CFG. Utility Diskette

The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original
packing until it is installed.

Unpacking and installation should be done in a grounded anti-static mat.
The operator should be wearing an anti-static wristband, grounded at the
same point as the anti-static mat.

Inspect the main board carton for obvious damages. Shipping and handling
may cause damages to your board. Be sure there are no shipping and
handling damages on the board before proceeding.

After opening the mainboard carton, extract the system board and place it
only on a grounded anti-static surface component side up. Again inspect the
board for damages. Press down on all of the socket IC's to make sure that
they are properly seated. Do this only with the board placed on an anti­static mat.

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN
DAMAGED!
MAKE SURE THAT THE POWER SUPPLY IS CONNECTED
TO THE PROPER 5V CONNECTOR!

5S1642-001-01

2.2 Installation

You are now ready to install your mainboard. The mounting hole pattern on
the mainboard matches the IBM-AT system board. It is assumed that the
chassis is designed for a standard IBM XT/AT mainboard mounting.

Place the chassis of the anti-static mat and remove the cover. Remove the
plastic clips, Nylon stand-off and screws for mounting the system board,
and keep them separately.

Each bank may use either 1-sided or 2-sided SIMMs.
All SIMMs must be Fast Page Mode DRAM with speeds less
than or equal to 70ns.
SIMM modules installed must be in pairs.

SIMM modules in parentheses ( ) are optional.

Refer to Fig. 3.1 for DRAM installation location. Pin-1 of the SIMM
module must match the Pin-1 of SIMM socket.

Insert the DRAM SIMM module into the socket at a 45 degree angle. If
the SIMM module is inserted on the wrong side, it can not be completly
plugged into the socket. After insertion, press the SIMM module in a
vertical direction until both left and right metal holders latch.

12S1462-001-01

3.3. Single CPU Installation

Seven types of CPU (75-166 MHz) can be used on S1462. The J9,
J10, J2 and J43 jumper will set up the system frequency generator for the
CPU on board. The following table and procedures tell how to install the
CPU.

J9 J10 J2 J43 CPU Speed

off off off off 75MHz

off on off off 90MHz

on on off off 100MHz

off on on off 120MHz

on on on off 133MHz

off on on on 150MHz

on on on on 166MHz

* J11 is always open.

* The CPU is a sensitive electric component and it can be easily
damaged by static electricity. Do not touch the CPU pins with your fin
gers.
* When installing the CPU into the socket, match the CPU pins to the
socket pins.
* Before the CPU is installed, the mainboard must be placed on a flat
plane in order to avoid being broken by the pressure of CPU insertion.

* A cooling fan and a heat sink assembly are required to go with the
CPU.

13S1642-001-01

3.4 Installing a Second Pentium

The mainboard can operate with either one or two Pentium proces­sors installed. In the Single Processor mode, with a Pentium P54C installed
in the lower socket, the mainboard will operate like a normal single Pentium
system. To use the Dual Processor mode you have to install a Pentium
P54C or P54CM. The mainboard default setup is for the Single Processor
operation. To install a second processor do the followings.

1.Set J41 to the Dual Processor setting

2.Make sure the second Pentium has the same an internal clock

speed as the the first CPU which has a multiple external clock

speed factor of 1.5.

Internal Clock External Clock

75MHz 50MHz(PCI Bus 25MHz)

90MHz 60MHz(PCI Bus 30MHz)

100MHz 66MHz(PCI Bus 33MHz)

120MHz 60MHz(PCI Bus 30MHz)

133MHz 66MHz(PCI Bus 33MHz)

150MHz 60MHz(PCI Bus 30MHz)

166MHz 66MHz(PCI Bus 33MHz)

In the table above, the 50, 60 and 66 MHz figures are oscillator speeds that
establish the external clock speed. The PCI Bus clock speed is fixed at one
half of the external clock speed.

3. Make sure the ZIF socket lever is up. To raise the lever, pull it out

to the side a little and raise it as far as it will go. The top plate will
slide back

4. Align the CPU and socket Pin 1 corners. The pins on the bottom

should align with the rows of holes in the socket.

5. Insert the CPU in the socket. It should insert easily. If it does

not, adjust the position of the lever a little.

6. Press the lever down. The top plate will slide foward. You will

feel some resistance as the presure starts to secure the CPU in

the socket. This is normal and will not damage the CPU.

When the CPU is installed, the lever should snap into place at the

side of the socket.

3.5 Operating Systems

With one processor installed you can use this mainboard with any one
processor Operating system that supports Intel CPUs. This includes MS­DOS and Windows in all versions as well as network operating systems
like Netware etc.

To use the Dual Processor option, you must use an Operating System that
supports the Intel MP Specification for multi-processing. Current avail­able options are:

Windows NT

Version 3.5 supports dual processing. For Version 3.1, you

can get the MP Specification V1.1 HAL installation kit from

Intel.

OS/2

OS/2 MP will be available shortly or may already be available by

the time you read this.

Upcoming releases

New releases of Novell Netware, SCO MPX and SunSoft

Solaries will also support multiprocessing.

15S1642-001-01

3.6 Upgrading Cache Memory (Standard SRAM Only)

Standard on S1462 is a 256KB 2nd level cache. It uses 8 32K*8 SRAM's
You can upgrade the cache to 512KB to improve system performance. It
uses 64K*8 SRAM's.

NOTICE: The 64K*8 SRAM chip is longer in length than the 32K*8
chip. Do not insert the 32 K*8 SRAM chip into the top four pin
holes of the socket, it could cause serious damage to your SRAM
chips. Refer to the diagram below.

All SRAM chips must be 20ns (nanoseconds) or faster. The chart below
shows the chips you need for each configuration.

3.7 Synchronouse SRAM Cache Memory

The synchronous SRAM can not be upgraded. Standard SRAM and Syn­chronous SRAM can not be installed at the same time. Once installed with
the Synchronous SRAM, the standard SRAM must be removed.

The table below is the configuration sizes of the SRAM:

3.8 CMOS RTC & EISA CFG SRAM

CMOS RTC includes an internal battery and Real Time Clock circuit. It
provides the date and the time to the system. CFG SRAM is used to keep
information of EISA device configuration for automatic system bootup.
Normally the life time of a RTC internal battery is 10 years. when replacing,
you should use the same model.

3.9 Speaker Connector Installation

S1462 provides a 4-Pin header J19 to connect the speaker. The polarity
can go either way.

3.10 Turbo Switch J16

Most case's panel has a turbo switch to control system speed. Slower
execution speed is required for the programs developed for the old XT.

Because Pentium cannot slow its clock speed on the fly, S1462 uses simu­lation method to implement TURBO switching function. The J12 on the
mainboard should be connected to the TURBO switch on case panel.

17S1642-001-01

3.11 Turbo LED Connector Installation

The TURBO LED on panel can indicate the current speed states of sys­tem. The TURBO LED connector should be installed to J17 in the correct
direcion.

3.12 Hardware Reset Switch Connetor Installation

The RESET switch on panel provides users with the HARDWARRE RE­SET functinon which is almost the same as power on/off. The system will
do a cold start after the RESET switch is pushed by the user. The RESET
switch is a 2 PIN connector and should be installed to J20 on mainboard.

3.13 Flash EPROM-Jumper J18

S1462 uses flash memory to store BIOS program. It can be updated as
new BIOS versions become available. The flash utility will guide you through
the process step by step. In some special cases, a non-programmable EPROM
is used on board.

J18 determines which type of EPROM is used. Short 2-3 for 5V flash chip
or EPROM. Short 1-2 for 12V flash chip. J18 is factory set to match the
on board BIOS chip. Please do not alter this Jumper.

3.14 Peripheral Device Installation

After controller jumpers setup, the mainboard can be mounted onto the
case. Then install the peripheral controller, display interface, and the disk
controller.

If the PCI-Bus device is to be installed in the system, any one of the four
PCI-Bus slots can be used no matter Slave or Master PCI-Bus device being
installed.

If the EISA-Bus drivers is to be installed in the system, only four Bus­Master devices can be installed. EISA slot 1 or slot 5, slot 2, slot 3 and
slot 4.

After installing the peripheral controller, the user should check everything
again, and prepare to power-on the system.

3.16 Connecting the Power Supply

There are two system power supply connectors on the mainboard. One
is for a 5 volt power supply, and the other is used for the 3.3 volt power
supply. If the power suply in a 3.3 volt mode, you can connect the leads
to the 3.3 volt connector. If the supply provides 5 volts only, you must
connect the leads to the 5 volt connector. Set the J29 on the "on" posi­tion.

other errors.

All, but Disk/Key The system boot will not stop for a keyboard or disk error; it

will stop for all other errors

* Memory

The category is for display-only and it is determined by POST Power On
Self Test of the BIOS.

Base Memory

The POST of the BIOS will determine the amount of
base (or conventional) memory installed in the system.
The value of the base memory is typically 512K for
systems with 512K memory installed on the motherboard,
or 640K for systems with 640K or more memory installed
on the motherboard.

Extended Memory

The BIOS determines how much extended memory is
present during the POST. This is the amount of
memory located above 1MB in the CPU's memory
address map.

28S1462-001-01

Expanded Memory

Expanded Memory is the memory defined by Lotus/Intel/
Microsoft (LIM) standard as EMS. Many standard DOS
applications can not utilize memory above 640K, the
Expanded Memory Specification (EMS) swaps memory
not used by DOS with a section, or frame, so these
applications can access all of the system memory.
Memory can be swapped by EMS is usually 64K within
1MB or memory above 1MB, depends on the chipset
design.
Expanded Memory device driver is required to use memory
as expanded memory.

Other Memory

This refers to memory located in the 640K to 1024K ad
dress space. This memory can be used for different
applications. DOS uses this area to load device drivers to
keep as muny convention memory free for application pro
grams as posible. Most use for this area is Shadow RAM.

5.4 Utility Setup

The WINBIOS Setup Options described in this section are
selected by choosing the Utility Setup Icon

Dectect Master

When select this ICON, the WINBIOS will do the automati­cally dectect of the Master IDE disk drive parameters and
report to Standard Setup Primary Master Manu.

Dectect Slave

When select this ICON, the WINBIOS will do the automati­cally dectect of the Slave IDE disk drive parameters and report
to Standard Setup Primary Slave Manu.

Color Set

Use this Icon to select WINBIOS Screen Color setting.

5.5 Security Manu Option

The WINBIOS Setup Options described in this section are
selected by choosing the Security Setup Icon

Password

Use this Icon to Setup the Password for the system

Anti-Virus

Enable or Disable the Anti-Virus option for the BIOS

5.6 Default Manu Option

There are three Default settings for the Setup Option: Original,
Optimal and Fail-Safe .

Original Setting

Use the Original Setting for the BIOS.

46S1462-001-01

Optimal Setting

The Optimal default setting is the best-case values that should
optimize system performance. If CMOS RAM is corrupted, the
Optimal setting is loaded automatically.

Fail-Safe Setting

The Fail-Safe settings provide far from optimal system perfor­mance, but are the most stable settings. Use this option as a
diagnostic aid if the system is behaving erratically

6.0 EISA CONFIGURATION UTILITY

The Extended Industry Standard Architecture (EISA) Configuration Utility
(ECU) is a software utility for doing system configuration. The advantage
of using this ECU is that it helps the EISA system to generate it's configura­tion settings automatically without conflict and provides information to the
user for the current settings and switches.
To run ECU utility, insert the ECU diskette into the floppy drive and then
type

CFG [Enter]
A ECU Setup Program will show on screen, following each step to complete
the ECU Setup.

7.0 Flash Writer Utility (Award)

Your mainboard comes with a utility to upgrade the BIOS. The BIOS
is stored on a ‘flash’ EPROM BIOS ROM chip on the mainboard that
can be erased and reprogrammed. This is what the Flash Memory
Writer (FMW) utility does. The utility is in the “Flash” directory on the
support floppy disk that comes with the mainboard. You will find three
files in the directory.

FLASH12.EXE -The Flash Memory Writer utility for

12V
FLASH5.EXE -The Flash Writer utility for 5V
README -A text file of instructions
S62AWXX.BIN -XX-A 2-digit version number.

Flash memory writer records (or ‘programs’) a new BIOS
onto the flash memory chip.

The BIOS file on the support disk may be newer than the
BIOS on the mainboard, so you may want to update your
BIOS right away.

48S1462-001-01

To reprogram the System BIOS, you must first do the following:

1. Check the jumper J18 setting.

For “5V Flash EPROM”, short pins 2 & 3 on J18.

For 12V Flash EPROM, short pins 1 & 2 on J18

The standard version of this mainboard uses a 12 volt flash
chip.

2. Make sure the CPU is running on the ‘real mode’.

FMW will not run if the CPU is operating in a protected or
virtual mode. This means that you can not run it with Windows
running or with any memory manager software. You must
disable any memory manager software first. The easiest way to
do this is to:

a. Boot your system from a bootable floppy disk with no
CONFIG.SYS or AUTOEXEC.BAT files, and then run Flash
Memory Writer from a backup copy of your support disk. You
can make your back-up floppy bootable when you format it, and
use one disk for both purposes.

b. If you are using MS-DOS 6.x, you can use the feature that
allows you to confirm or abort each line of the CONFIG.SYS
file. You do this while pressing <F8> while the “Starting MS­DOS...” line is on the screen.

There are other ways to accomplish the same result. The main
point is to make sure no memory managers are running. If you
are not sure, try running FMW. If it runs, then you have suc
ceeded. If it displays a warning message about the CPU
mode, you will have to try again.

49S1642-001-01

Once you have satisfied the two requirements mentioned above,
you can run FMW. You can copy the contents of the “Flash”
directory to your hard drive, or you can the utility from a backup
of the support floppy disk. Make sure the new BIOS file is in the
same directory as the FMW utility.

To run FMW, change to the “Flash” directory if you are not al­ready in it. Type “Flash12” at the DOS command line and press
the <Enter> key. The following screen will appear.

7.2 The Flash Memory Writer Utility Screen (Award)

FLASH MEMORY WRITER V1.1

Copyright (C) 1993, AWARD Software Inc.,

For MERCURY EISA-3B09700 1/10/
1994
Flash Type-28F00/12V

File Name to Program:

Error Message:

When you type in the whole file name, e.g. A52AW10.BIN and

confirm that you want to program the BIOS. The utility will then ‘Blank’,
‘Erase’, and then ‘Program’ the flash memory on the mainboard with the
new BIOS file. So you better choose “yes” to save the original system
BIOS to a floppy diskette before you program the new BIOS. This
leaves you with a backup of your original BIOS in case you need to re­install it. This option is highly recommended. If you can not sucessfully
program the BIOS file for whatever reason, re-install you original BIOS
from the backup file.

Warning: If you do not successfully install a complete BIOS file

in the flash memory on the Mainboard, your system may not be able to
boot. If this happens, it will require service by your system vendor.
Follow the requirements and instruction in this section precisely to aviod
inconvienience.
