Static electricity can easily damage your SQ 596 mainboard. By observing a few basic
precaution can help you safeguard against damage that could result in expensive repairs.
Follow the simple measures below to protect your equipment from static electricity damage:
Keep the mainboard and other system components in their anti-static packaging until you are
ready to install them.
Touch a grounded surface before you remove any system component from its protective antistatic packaging. 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 points as the
anti-static mat.
After removing the mainboard from its original packing, only place it on a grounded, antistatic surface component side up. Immediately inspect the board for damage. Due to shifting
during shipping, it is suggested that the installer press down on all of the socket ICs to
ensure they are properly seated. Do this only with the board placed on a firm flat surface.
During configuration and installation, touch a grounded surface frequently to discharge any
static electrical charge that may have built up in your body. The best precaution is to wear a
grounded wrist strap. When handling the mainboard or an adapter card avoid touching its
components. Handle the mainboard and adapter cards either by the edges or by the adapter
card s case mounting bracket.

Installation Steps
Jumper Settings
You can configure the hardware options by setting jumpers on the mainboard. A jumper is a
set of two or more metal pins in a plastic base attached to the mainboard. A plastic jumper
cap with a metal(conductive) plates inside fits over two pins to create an electrical contact
or short between them. This contact establishes a hardware setting and is referred to as a
closed jumper setting.
Some jumper have two pins while others may have three or more. Jumpers are sometimes
combined into sets called jumper blocks where all the jumpers in the block must be set
together to establish a hardware setting. In this manual the jumper settings will be described
graphically using a triangle ( )always marking pin 1. Those jumpers with two pins will be
shown as closed and open. A jumper is referred to as closed by placing the plastic jumper
cap over the two jumper pins and as open by removing the jumper cap. Some jumpers are
oriented vertically and other horizontally with pin 1 marked as (=P1).

CMOS RAM Settings(Clear CMOS Data) (JP14)
The JP14 allows you to discharge the SQ596 mainboard CMOS memory and Real Time
Clock (RTC) data. The CMOS memory maintains the system configuration information and
the RTC provides the system with the date and time. Make sure this jumper is open for
normal operation.
Normal Mode
Clear CMOS
(Default)
Clear CMOS procedure :
The SQ596 mainboard uses a Benchmarq BQ3287AMT or DS12B887 chip. To clear the
stored CMOS data, power on with the JP14 closed and then do the following: 1) With the
system turned off, close JP14 2) Power on for a few seconds 3)Power off 4) Remove
JP14 5) Power on 6) Re-setup the BIOS (note: to bring up the BIOS setup menu, hold
down <DEL> during the system boot sequence)
NOTICE: Under some circumstances it is possible that the CMOS configuration settings
may be lost or corrupted causing the system to malfunction. This is not a serious problem. If
this happens, run the BIOS setup utility and re-enter your configuration settings. When you
restart the computer, the system should work normally.
CPU Type Selection {JP7,JP8,JP4(=BF0),JP5(= BF1)}
The system speed depends upon the frequency of CLOCK GENERATOR which is
determined by jumpers. These jumpers tell the system what speed to run at. Currently, this
mainboard speed range is from 75MHz to 200MHz. The CPU input frequency must match
the frequency of CLOCK GEN or it will cause the system to malfunction. For example,
setting a 75MHz CPU to run at 90MHz will cause the system to malfunction.

Expansion Slots
The SQ596 has 7 expansion slots on-board. Three are 16-bit ISA Bus expansion connectors
and four are 32-bit PCI expansion slots (include 1 shared) . One of the expansion slots is
SQ596
11
shared by connectors that will accommodate either an ISA or a PCI expansion card, but not
both at the same time. All four PCI expansion slots accept PCI Bus master cards and fully
support the PCI 2.1 specification.
SIMM Slots - System Memory (DRAM)
You can configure the system memory size in a variety of ways by in using different
combinations of the Four 72-pin DRAM SIMM modules. The memory must be 70ns(nano
seconds) or faster using either Fast Page Mode or Extended Data Output (EDO) types. The
memory table below shows the different memory size combinations available. Please pay
attention to the following restrictions :
You must use one pair of sockets at a time in sequence ( i.e.
SIMM1 and SIMM2, or all four sockets at once).
Each pair of modules must be the same size and speed and may
be single sided or double-side. Module sizes: Single-side SIMMs: 4MB,16MB;
Double-side SIMMs: 8MB,32MB
IMPORTANT: To support parity ECC check detection , you must use True 36-bit parity
type DRAM (i.e. 8 data chips + 4 parity chips) . Mixing 32-bit non parity DRAM (i.e 8
chips) and 36-bit parity DRAM will cancel the parity check detection feature.
PIN1 of the SIMM module must match with the PIN1 of the
SIMM socket.
The module will only insert into the socket one way. An
orientation cut-out will prevent you from inserting it the wrong way.
Insert the DRAM module into the SIMM socket at a 45 degree
angle. If pin 1 of the SIMM does not line up with pin 1 of the socket, the SIMM will
not insert into the socket. After inserting the SIMM module completely into socket,
push the SIMM module into a vertical position.
The module should click into place with the retaining clips at
each end of the socket snapping behind the module to secure it.
To release the memory module push both retaining clips
outwards and carefully rock the module forward.

The SQ596 provides an upgradeable secondary (second level or L2) cache using Pipeline
Burst SRAM. The Pipeline Burst (PB) SRAM provides performance similar to expensive
Synchronous Burst SRAM for only a slight cost premium over slower performing
Asynchronous SRAMs. The SQ596 mainboard defaults with 0K cache on-board, with a
second-level cache module you are able o upgrade to 256KB or 512KB. Instructions on how
to insert the cache modules are shown below.
NOTICE: The number of pins are different on either side of the break, therefore the module
will only fit in the orientation as shown.

ZIF Socket 7 for Central Processing Unit(CPU)
The SQ596 comes with a 321-pin ZIF socket 7 for installing the CPU. The Socket 7 will also
support future Pentium up-grade processors. It is strongly recommended that a heatsink and
CPU cooling fan be used to prevent the CPU from overheating. (Tip) Applying a thermal
jelly between the CPU and the heatsink/fan will furture cool the CPU.
Installation Procedure(CPU)
To install a CPU, remember to take careful precaution against static electric discharge. The
basic procedure is as follows:
IMPORTANT: You must set jumpers JP7,JP8, JP4 & JP5 to the correct bus frequency
ratio as instructed on page 6-8 of Section 3 .
Turn off your system and disconnect the power source.
Remove the existing CPU from the ZIF socket by pulling the ZIF
lever upwards at a 90 degree angle.
Insert the CPU with the correct orientation as below shown. Use
the notched (white dot) corner of the CPU as your guide. The notch in the corner of
the CPU should correspond with PIN 1 of the ZIF socket (Notice: Pin 1 is the blank
corner of the ZIF socket with one hole missing)
Once the CPU is inserted close the socket’s lever.
WARNING: Without a fan, the CPU can overheat and will cause damage to both the CPU
and the SQ596 mainboard.

Installation Procedure:
To install expansion cards, please read the expansion card’s documentation for instructions.
NOTICE: Some expansion cards require an IRQ to work and may cause a conflict. There
are total of 16 IRQs but only 6 are free for expansion cards. In case of a conflict please
contact the system manufacturer for technical support.
There are two types of ISA expansion cards, design-Legacy and PnP(Plug & Play). For
Legacy cards you must set the cards’ jumpers manually. For Plug & Play cards, your system
will arrange the IRQs automatically. You can verify the IRQ allocation either by using
Microsoft’s Diagnostic (MSD.EXE) utility which is in the Windows directory or through the
Windows 95 resources menu. An IRQ is automatically assigned to PCI expansion card. All
the PCI slots on the mainboard use an interrupt . Be sure that the jumpers on your PCI cards
are set to interrupt A.

stopped and you will be prompted.
All errorsThe system boot will not be stopped for any error that may be
detected.
All, But DisketteThe system boot will not stop for a disk error; it will stop for all
other errors.
All, But Disk/KeyThe system boot will not stop for a keyboard or disk error; it
will stop for all other errors.
Memory
The category is display-only which 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 mainboard, or 640K for systems with 640K or more memory
installed on the mainboard.
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.
Other Memory
This refers to the memory located in the 640K to 1024K address space. This is memory that
can be used for different applications. DOS uses this area to load device drivers to keep as
much base memory free for application programs. Most use for this area is Shadow RAM.
Total Memory
System total memory is the sum of base memory, extended memory, and other memory.

is Enable.
Quick Power On Self Test
This category speeds up Power On Self Test (POST) after you power on the computer. If it
is set to Enable, BIOS will shorten or skip some check items during POST.
Boot Sequence
This category determines which drive computer searches first for the disk operating system
(i.e., DOS).
C,ASystem will first search for hard disk drive then floppy disk drive.
A,CSystem will first search for floppy disk drive then hard disk drive.
Note: This function is only available for IDE type, SCSI type is always boot from A.
Swap Floppy Drive
This category allows you to swap two floppy disk drives for reading or writing data. When
enabled the BIOS swaps floppy disk drive assignments, so that Drive A becomes Drive B,
and Drive B becomes A.
Boot Up Floppy Seek
During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks.
360K type is 40 tracks while 760K, 1.2M and 1.44M are all 80 tracks.
EnabledBIOS searches for floppy disk drive to determine if it is 40 or 80 tracks.
Note that BIOS can not tell from 720K, 1.2M or 1.44M drive type as they
are all 80 tracks.
DisabledBIOS will not search for the type of floppy disk drive by track number.
Note that there will not be any warning message if the drive installed is

On-Chip Primary PCI IDE
As stated above, your system includes two built-in IDE controllers, both of which operate on
the PCI bus. This setup item allows you either to enable or disable the primary controller.
You might choose to disable the controller if you were to add a higher performance or
specialized controller.
EnabledPrimary HDD controller used -- Default
DisabledPrimary HDD controller not used.
On-Chip Secondary PCI IDE
As above for the Primary controller, this setup item allows either to enable or disable the
secondary controller. You might choose to disable the controller if you were to add a higher
performance or specialized controller.
EnabledPrimary HDD controller used
DisabledPrimary HDD controller not used.
IDE PIO
IDE hard drive controllers can support up to two separate hard drives. These drives have a
master/slave relationship which is determined by the cabling configuration used to attach
them to the controller. Your system supports two IDE controllers--a primary and a
secondary--so you have the ability to install up to four separate hard disks.
PIO means Programmed Input Output. Rather than have the BIOS issue a series of
commands to effect a transfer to or from the disk drive, PIO allows the BIOS to tell the
controller what it wants and then let the controller and the CPU perform the complete task
by themselves. This simpler faster and more efficient.
Your system supports five modes, numbered from 0 (default) to 4, which primarily differ in
timing. When Auto is selected, the BIOS will select the best available mode. This is true
for the next four setup items:
