1. Introduction
1.1 Overview
The S1562 is a quality, high performance dual processor mainboard based
on the powerful Intel Pentium microprocessors. This mainboard is
designed around the latest and fastest Intel 430HX(II) chipset and can
support CPU speeds of 75MHz through 200MHz and beyond. The
S1562S is single processor mainboard and the S1562D is a dual
processor mainboard.
The S1562S supports Pentium and Cyrix processors, EDO memory, ECC
memory and memory parity checking.The S1562's PCI Local Bus
provides high performance capabilities that are ideal for a wide range of
demanding applications such as: CAD, CAM, CAE, networking, multiuser environments, database management, desktop publishing, image
processing and 3D animation. The S1562D supports dual Pentium
processors(dual Cyrix CPU is not supported).
This integrated system board achieves the highest reliability and yet is
small enough for all of its features to be supported in a "Baby-AT" formfactor. Some of the features included are: on-board dual channel PCI
IDE, on-board floppy controller, on-board high speed I/O, and support for
pipeline-burst SRAM.
Flexibility and expandibility have been designed into the S1562. With I/O
and drive controller support built on-board, the four PCI and five ISA
(One ISA and one PCI as a shared slot) slots are free for any add-on
expansion cards. With eight SIMM sockets, the S1562 can provide a very
flexible memory configuration of 8MB to 512MB of RAM. With the
S1562D's support for dual Pentium processors, you can start a system
with just one CPU, and later add another, when more processing power is
required.

2. Board Installation
2.1 Unpacking
The mainboard package should contain the following:
wS1562 Mainboard
wOne IDE 40 pin cable
wTwo serial cables
wwOne parallel cable
wOne 34 pin floppy cable
wUser's Manual
wOptional Pipeline cache module
wOptional PS/2 mouse cable
The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original
packaging until it is ready to be installed.
Unpacking and installation should be done on 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 mainboard carton for obvious damage. Shipping and handling
may cause damage to your board. Be sure there is no shipping and handling
damage to 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!

3.3 CMOS RTC
CMOS RTC includes an internal battery and Real Time Clock circuit. It
provides the date and the time for the system. Normally the life span of a
RTC internal battery is 10 years. When replacing, you should use the same
model.
3.4 Speaker Connector Installation
S1562 provides a 4-Pin header (J23) to connect the speaker. The polarity
can go either way.
3.5 Turbo Switch
The front panel on your case may have a turbo switch to control system
speed when slower program execution is required for software developed
in the old XT days.
The Intel 430HX chipset doesn't support a de-turbo mode, but the S1562
has a connector (J26) for the cable that may come with the case.
3.6 Turbo LED Connector Installation
The TURBO LED on the front case panel can indicate the current speed
status of the system. The TURBO LED connector should be installed to
J25 in the correct direction.
12S1562-001-01
3.7 Hardware Reset Switch Connector Installation
The RESET switch on your cases' display panel provides users with the
HARDWARE RESET function which is 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 on jumper
J27.
3.8 Flash EEPROM-Jumper J47and J48
The S1562 uses flash memory to store BIOS data. It can be updated as
new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step. If your system is functioning properly,
you may want to forego updating your BIOS in the event the new one
causes problems with your existing hardware and software.
J47 and J48 determines which type of EPROM is used. These jumpers
have been set to match the on board BIOS chip. The factory default for the
S1562 is on pins 1-2.
Refer to chapter 6 for Flash EEPROM upgrade procedures.
3.9 Hardware CMOS & Password Reset
(The following steps are valid provided the board has a DS12887A RTC)
If you have been locked out of your system because you forgot your password or set the CMOS incorrectly, follow the instructions below.
a. Power off the system
b. Short jumper J46.
c. Wait for 5 seconds then remove the jumper from J46.
d.Then power on the system again.
By doing the above procedures, your password will be erased and the CMOS
will be reset to the BIOS defaults.
13S1562-001-01
3.10 DRAM Installation
The S1562 uses a 64-bit data path from memory to CPU and can
accommodate up to 512 MB of RAM. The mainboard supports
standard, EDO (Extended Data Out) and ECC(Error Correcting Code)
72 pin SIMMS . All installed memory will be automatically detected so
there is no need to set jumpers.
wSIMM modules must be installed in pairs.
wEach pair of SIMMs must be of the same size and type.
wThe mainboard supports 1, 2, 4, 8 and 16MBx32 SIMMS.
wThe table below shows some of the available memory configurations.

3.11 CPU Installation
Many types of Pentiums (75 thru 200 MHz) and Cyrix CPUs can be
used on the S1562. Please refer to the previous pages for the correct CPU
jumper settings for your board.
w The CPU is a sensitive electronic component and it can be easily
damaged by static electricity. Do not touch the CPU pins with your
fingers.
w When installing the CPU into the socket, match the CPU pins to the
socket pins.
w 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.
w A cooling fan and heat sink assembly is required to protect the
CPU from being damaged.
1. 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.
2. Align the CPU and socket Pin 1 corners. The pins on the bottom
of the CPU should align with the rows of holes in the socket.
3. Insert the CPU in the socket. It should insert easily. If it does
not, adjust the position of the lever a little.
4. Press the lever down. The top plate will slide forward. You will
feel some resistance as the pressure 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 in the down position..
17S1562-001-01
3.12 Upgrading Cache Memory
The S1562 supports synchronous pipeline burst SRAM. The synchronous
pipeline burst cache uses a "COAST Module" that is plugged into the
"COAST " socket connector which is located between the CPU and the
SIMM sockets.
wThe BIOS will auto detect the cache size so a you don't need to change
any jumpers.
wThe pipline burst cache COAST module comes in either 256KB or
512KB sizes and has a built in Tag RAM chip.
wThe "COAST Module" will only fit in the "Coast Socket" one way, and
should install easily.
If you have a 512kb or 256kb cache module that has one 32kb X 8kb
tag chip then the cacheable range is the first 64Mb of memory. If your
module has two 32kb X 8kb tag chips then the cacheable range is
512Mb of RAM.
If you have only one tag RAM chip on your cache module but would
like to be able to cache the whole 512Mb memory range, then do
the following.
1. Add a 32k X 8k 15ns SRAM chip to U9.
2. Close jumper J17.(The default is open)
3. Jumper J18 to pins 1-2.(The default is 2-3)
18S1562-001-01
3.13 Understanding The Different Clock Speeds
The following chart shows the different CPU, mainboard and PCI frequencies. As you may have noticed, all the Intel Pentium CPUs use an
internal clock multiplier(x3, x2.5, x2 or x1.5 Motherboard speed). All
Cyrix 6x86 can only use a x2 clock mulitipplier.
Pentium Mainboard PCI Bus
Internal Clock Clock Clock
75 MHz 50 MHz 25 MHz
90 MHz 60 MHz 30 MHz
100 MHz 66.67 MHz 33 MHz
120 MHz 60 MHz 30 MHz
133 MHz 66.67MHz 33 MHz
150 MHz 60 MHz 30 MHz

200 MHz 66.67 MHz 33 MHz
In the table above, the 50, 60 and 66.67 MHz figures are oscillator speeds
that establish the external clock speed. The PCI Bus clock speed is fixed at
one half of the mainboard clock speed. The 150MHz Pentium when set for
2.5x mode will achieve a 30MHz PCI bus speed but if it is set for 3x mode
you will get a slower 25MHz PCI bus speed.
Since all of the Cyrix 6x86 CPU's use a x2 mulitplier, the 100MHz P120+
must run on a 50MHz host bus. The PCI speed will then be at 25MHz.

3.14 Peripheral Device Installation
After all the jumpers on the mainboard have been set, then it can be mounted
into the case. Then proceed to instalL the display card and any other
peripheral devices.
If a PCI-Bus interface card is to be installed in the system, any one of the
four PCI-Bus slots can support either a Master or a Slave device.
After installing the peripheral controller, the user should check everything
again, and prepare to power-on the system.

To connect the leads from either voltage power supply, you should first
make sure the power supply is unplugged. Most power supplies have two
leads. Each lead has six wires, two of which are black.
Orient the connectors so the black wires are in the middle of the
5V power supply.
Caution: Some power supplies also include "3V" connectors. The
connection wires normally have two colors with 3 black wires on
one side. Please be very careful. Don't to use the wrong connector.

All, but Disk/Key The system boot will not stop for a keyboard or disk
error; it will stop for all other errors.
ww 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 640K.
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.
29S1562-001-01
Expanded Memory
Expanded Memory (EMS) defines a 64 K page frame in
the area between 640K and 1Mb containing four 16K pages
that are windows into the EMS memory. Programs issue
requests to the EMS manager to switch the page to any
part of EMS memory. Extended memory can be converted
to emulate EMS by using a memory manager such as
EMM386 that ships with Windows and DOS.
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 much conventional memory free for application
programs as possible.

ww Chipset Features
The DRAM timings can be altered from the default to optimize system
performance. Be aware though that these settings are sensitive to the
type and speed of DRAMs being used and can cause lockups or data
lost if set incorrectly. The default settings should work with most
DRAMs.
w DRAM RAS# Precharge Time
DRAM must continually be refreshed or it will lose its data. Normally,
DRAM is refreshed entirely as the result of a single request. This option
allows you to determine the number of CPU clocks allocated for the
Row Address Strobe to accumulate its charge before the DRAM is
refreshed. If insufficient time is allowed, refresh may be incomplete
and data will be lost. A lower setting may increase performance.
The default value is 4 clocks.
wwDRAM R/W Leadoff Timing
This sets the number of CPU clocks allowed before reads and
writes to DRAM are performed. The default of 8/7 would set the
leadoff timing for reads to eight clocks and writes to seven clocks.
A lower setting may increase performance.
The default value is 8/7.
ww DRAM RAS to CAS Delay
When DRAM is refreshed, both rows and columns are addressed
separately. This option allows you to determine the timing of the
transition from Row Address Strobe (RAS) to Column Address
Strobe(CAS). A lower setting may increase performance.
The default is 3 cpu clock delay.
wwDRAM Read/Write Burst Timing
This sets the timing for Burst mode reads from DRAM. Burst read and
write requests are generated by the CPU in four separate parts. The
"x" is the leadoff cycle and is determined by the chipset and the memory
timing. The remaining four numbers is the actual data cycles. The lower
the timing numbers, the faster the system will address memory.
The default for read burst timing is x4444.
The default for write burst timing is x4444.
34S1562-001-01
wwSpeculative Leadoff
The 430HX chipset is capable of allowing a DRAM read request to be
generated slightly before the address has been fully decoded. This can
reduce all read latencies.
More simply, the CPU will issue a read request and included with this
request is the place(address) in memory where the desired data is to be
found. This request is received by the DRAM controller. When enabled,
the controller will issue the read command slightly before it has finished
determining the address.
The default is disabled.
wwTurn-Around Insertion
When this is enabled, the chipset will insert one extra clock to the
turn-around of back to back DRAM cycles.
The default is disabled.
ww System BIOS Cacheable
When enabled, accesses to the system BIOS ROM addressed at
F0000H-FFFFFH are cached. Enable this for best performance under
DOS/Windows or Windows95. When using operating systems that do
not access the BIOS (Unix, OS/2, NT, etc...) this setting can be
disabled.
The default is enabled.
wwVideo BIOS Cacheable
As with caching the system BIOS above, enabling the Video BIOS
cache will cause access to the video BOS addressed at C0000h to
C7FFFFh to be cached.
The default is enabled.
ww8/16 bit I/O Recovery Time
The recovery time is the length of time measured in CPU clocks, which
the system will delay after the completion of an I/O request. This delay
takes place because the CPU is operationg so much faster than the
I/O bus that the CPU must be delayed to allow for the completion of the
I/O request. This option allows you to determine the recovery time
allowed for 8/16 bit I/O.
The default is 1 clock cycle.
35S1562-001-01
wwMemory Hole at 15M-16M
Some ISA cards may not function correctly when more than 16MB of
RAM is installed. If this is the case, then enable this option. Most ISA
card should work fine with this option disabled.
The default is disabled.
wwIDE HDD Block Mode
This option allows the hard disk controller to use fast block mode
transfer to and from the hard disk drive. The hard drive must support
block mode transfer for this option to be enabled.(Most new drives do.)
If you are not sure if your drive supports this, call your hard drive
vendor. The default is enabled.
wwIDE 32-bit Transfer Mode
Enabling 32-bit transfer mode allows faster access to data on your hard
disk drive. Not all drives will support this feature.
The default is enabled.
wwIDE Primary/Secondary Master/Slave PIO
Rather than have the BIOS issue a series of commands to effect a
transfer to or from the disk drive, PIO(Programmed Input/Output)
allows the BIOS to tell the controller what it wants and lets the
controller and the CPU perform the complete task themselves. This
method is simpler, more efficeint and faster. This BIOS supports five
modes (0 thru 4) and can be set by the user or set to Auto detect.
The default is Auto.
wwOn-Chip Primary/Secondary PCI IDE
This option enables or disables the on board PCI IDE controllers.
The default is enabled.
wwPCI Slot IDE 2nd Channel
This option allows you to designate an IDE controller board inserted into
one of the physical PCI slots as a secondary IDE controller. If you don't
have a third party PCI IDE controller installed, this option should be
disabled. The default is disabled.
36S1562-001-01
wwPeer Concurrency
When enabled, multiple PCI devices can be active at any one time.
When disabled, only one PCI device can have access to the PCI bus.
at any one time. The default is Enabled.
wwChipset Special Features
When disabled, the chipset behaves as if it were the earlier 430FX
chipset. This option should be enabled for best performance.
The default is Enabled.
wwDRAM ECC/Parity Select
This item allows you to select between two methods of DRAM error
checking, ECC or Parity. Must have parity SIMMs to select ECC or
Parity. The ECC algorithm is built into the chipset and can correct
one bit errors. The default is Parity.
wwOnboard FDC Controller
This option lets you enable or disable the onboard floppy controller.
The default is enabled.
wwOnboard Serial Port 1/2
This option lets you select how this port will be addressed. The options
are Com1 thru Com4 or disabled.
The default is Com1for port 1 and Com2 for port 2.
wwOnboard Parallel Port
This option lets you select the LPT port address. Options are
3BC/IRQ7, 378/IRQ7, 278/IRQ5 or Disabled.
Note: Cannot use EPP or ECP+EPP when using 3BC/IRQ7
The default is 378/IRQ7.
wwParallel Port Mode
This option lets you select which mode the parallel port will run in. The
options are Normal, EPP, ECP, or ECP + EPP.
Normal- Standard parallel port mode.
EPP - Bi-directional mode.
ECP - Fast, buffered mode.
EPP/ECP- Bi-directional and buffered.
Check the documentation of your device to see how it needs to be set.
The default is Normal.

(50mhz, 60mhz or 66mhz). The default depends on CPU speed.
♦Turbo Read LeadOff
A feature to enable the skipping of the first input register in the DRAM
data pipeline. This results in a 1 HCLK savings of all READ leadoff
timings.
♦Read/Write Burst Timing
Allows customizing of the read timings in the memory design.
The options are x2222, x3333 and x4444. The lower the number, the
faster the DRAM will be accessed.

final memory target (main memory, cache, or PCI) is decoded. This
results in a 1 HCLK increase in DRAM read leadoff latencies.
The default is disabled.
♦Turn-Around Insertion
When enabled the chipset inserts 1 extra clock of turnaround on the MD
lines after asserting memory write enable (MWE#).
51S1562-001-01

bit error (MBE) or parity error. The default is disabled.
♦Bad Parity On Uncorrectable Error
The TXC forces bad parity on PCI read data starting from the time an
uncorrectable DRAM error is detected,until the end of the current
cycle. The default is disabled.
♦PCI 2.1 Passive Release Enable
If enabled, this option causes the PIIX3 to use the passive release
mechanism on the PHOLD# signal. If disabled the PHOLD# signal
behaves as it did previously with the Triton I chipset.
The default is enabled.

6.0 Flash Writer Utility
You can upgrade the BIOS of your mainboard by using a "Flash
Memory Writer"(FMW) utility. This utility can be downloaded from the
factory's BBS(Consult your system vendor for the phone #). The
system BIOS is stored on a 'flash' EPROM chip on the mainboard
which can be erased and reprogrammed by the FMW.
The following three files make up the FMW.
AWDFLASH.EXE -The Flash Memory Writer utility for
Award to Award upgrade.
AMIFLASH.COM -The Flash Memory Writer utility for
AMI to AMI upgrade.
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. You cannot upgrade an Award
BIOS to a AMI BIOS or a AMI BIOS to an Award BIOS.
*This file name is subject to change and can have either a "bin" or a
"rom" extension.
57S1562-001-01
To reprogram the System BIOS, you must first do the following:
1. Check jumpers J47 and J48
The S1562 uses a 5V Flash EPROM so these three jumpers
should be left in the default postion on pins 1 and 2. These
jumpers should never be moved.
2. Make sure the CPU is running in ‘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 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 bypass the CONFIG.SYS and AUTOEXEC.BAT
file. You do this while pressing <F5> while the “Starting MS-
DOS...” 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 succeeded. If it displays a warning message about the CPU
mode, you will have to try again.
58S1562-001-01
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 run the utility from a
backupof the support floppy disk. Make sure the new BIOS file
is in thesame directory as the FMW utility.
To run FMW, change to the “Flash” directory if you are not already in it. Type “Awdflash” at the DOS command line and press
the <Enter> key. The following screen will appear.
6.1 The Flash Memory Writer Utility Screen (Award)
FLASH MEMORY WRITER V3.0
Copyright (C) 1993, AWARD Software Inc.,
For FX/HX-2A59CT51 Date:4/13/95
File Name to Program:
Error Message:
Type in the whole file name, e.g. A62AW10.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. You should 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 instructions in this section precisely to aviod
inconvenience.
