Static Electricity Precaution
Static electricity can easily damage your SQ594 mainboard. By
observing a few basic precautions can help 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 anti-static 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 packaging, only place it
on a grounded, anti-static 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 case mounting bracket.

Installation Steps
Jumper Settings
You can configure the hardware options by setting jumper 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) plate 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 jumpers 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 as graphically using a (s)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 (s=P1).

CMOS Settings(Operation/Clear CMOS Data) (JP10)
The JP10 allows you to clear the SQ594 mainboard CMOS memory and Real Time Clock
(RTC) data. The CMOS memory maintains the system configuration information and RTC
provides the system with the date and time. Make sure this jumper is open for normal
operation.
Normal (Default) Clear CMOS
Clear CMOS procedure :
To clear the stored CMOS data, do the following :
1) the system turned off, ⇒ 2) close JP10 ⇒ 3) Open JP10 ⇒ 4) ⇒ Power on ⇒ 5) Re-
setup the BIOS (refer to enter 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 Speed Selection (JP2, JP3, JP4, JP5)
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 SQ594 has 7 expansion Slots On-board, there are 3 16-bit ISA, and 4 32-bit PCI
expansion Slots. (Includes one share)
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 a 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.
1. There are two types of ISA expansion cards, design-Legacy and P-n-P (Plug & Play).
For Legacy cards you must set the card‘s jumpers manually. For Plug and Play cards,
your system will arrange the IRQs and DMAs 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.
2. An IRQ is automatically assigned to PCI expansion cards. All of the PCI slots on the
mainboard use an interrupt. Be sure that the jumpers on your PCI cards are set to
interrupt A.
System Memory
IMPORTANT: The SQ594 System memory can support 5V Fast Page Mode or EDO
DIMM, JP1 is default set to 3.3V, please reset it to 5V location once you are using 5V
DIMM.

System Memory - SIMM Slots (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 chart below shows the different memory size combinations available. Please pay
attention to the following restrictions:
1) 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 either single sided or double-sided.

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 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.
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.

IDE PIO
IDE hard drive controllers can support up to two separate hard drives. These drives have a
master/slave relationship which are 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 to 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 and more efficient (and faster).
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:
IDE Primary Master PIO
