Static Electricity Precaution

Static electricity can easily damage your SQ593 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:

1. Keep the mainboard and other system components in their

anti-static packaging until you are ready to install them.

2. 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.

3. 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.

4. 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

SQ 593

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 ( )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).

Clear CMOS procedure :

The SQ593 mainboard uses a Benchmarq BQ3285S chip. To clear the stored CMOS data, power on with the JP3 closed and then do the following :

1) With the system turned off, close JP3 ⇒ 2) Power on for a few seconds ⇒ 3) Power off ⇒ 4) Open JP3 ⇒ 5) Power on ⇒ 6) 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

SQ 593

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 and Selection {JP7,JP8,JP9(=BF0),JP10(= 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.

NOTICE: When installing the CPU into the CPU socket, be sure that PIN 1 of the CPU is in the same corner as the PIN 1 of socket. The CPU is an extremely sensitive electric component and can be easily damaged by static electricity.

Expansion Slots

The SQ593 has 7 expansion Slots On-board, there are 3 16-bit ISA, 1 8-bit ISA, and 3 32-bit PCI expansion Slots (includes 1 shared).

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 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.

2) Module sizes: Single-side SIMMs: 4MB, 16MB

3) Double-side SIMMs: 8MB, 32MB, 64MB

IMPORTANT: To support parity 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.

Installation Procedure for System Memory

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.

IMPORTANT: Do not use SIMM modules that use an extra TTL chip to convert the memory module from asymmetric to symmetric.

Installation Procedure(CPU)

Notch

Blank Corne

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, JP9 & JP10 to

correct Bus frequency ratio as instructed on page 6-7 of this section .

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 corner of the CPU as your guide. The notch in the corner of the CPU should correspond with PIN1 of the ZIF socket (Notice: Pin 1 is the blank corner of the ZIF socket with one pin 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 SQ593 motherboard.

The SQ593 mainboard has one 8-bit ISA, three 16-bit ISA and three 32-bit PCI Slots.

SQ 593

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.

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 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 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.

The 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 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.

SQ 593

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 IDE Primary Slave PIO IDE Secondary Master PIO IDE Secondary Slave PIO

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.
