PCI/ISA System Board

v Introduction

The G586OPC system board offers several advanced features integrated into the system board. Its design is based on the new Peripheral Component Interconnect

(PCI) local bus and Industry Standard Architecture

(ISA) standards.

The G586OPC provides a 321-pin Zero Insertion Force

(ZIF) CPU socket for Pentium TM processors running at

75MHz, 90MHz, 100MHz, 120MHz, 133MHz or

150MHz frequency. This ZIF socket allows users to easily upgrade their CPUs. It also provides a VRM

(Voltage Regulation Module) header allowing you to upgrade to future low-voltage CPUs.

The G586OPC is equipped with three PCI slots, three

ISA slots and one shared PCI/ISA slot.

The G586OPC board has two bus master PCI IDE connectors. Bus mastering reduces CPU use during disk transfer. The system board is also equipped with two

NS16C550A-compatible serial ports, an SPP/EPP/ECP parallel port, a floppy disk drive controller, one PS/2 mouse port and one PS/2 keyboard connector.

The G586OPC can support 2MB to 128MB of memory using 256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and

8Mx36 72-pin SIM modules.

G586OPC

v Installation Overview

This chapter summarizes the steps in installing the

G586OPC system board into your system unit. It also includes a description of the area in which you must work and directions for memory installation. Before installing the system board, obtain the memory you plan to install. Please refer to the memory chart, on pages 8 and 9, for the number and type of SIM modules needed for the amount of memory you require.

Preparing the Area

Before unpacking the system board, make sure the location you have selected is relatively free of dust and static electricity. Excessive exposure to dust, static electricity, direct sunlight, excessive humidity, extreme cold, and water can damage the operational capabilities of your system board. Avoid placing the unit on surfaces such as carpeted floors. These areas attract static electricity which can damage some circuits on your system board.

Make sure the power source has a properly grounded, three-pronged socket. It is essential that the power connection be properly grounded for correct functioning of your system board. For further protection, we recommend that you use a surge suppressor. This will protect the system board from damage that may result from a power surge on the electrical line.

Move items that generate magnetic fields away from your system board, since magnetic fields can also damage your system board. Once you have selected the

6

PCI/ISA System Board

7 ideal location, unpack the G586OPC system board carefully.

Handling the System Board

It is quite easy to inadvertently damage your system board even before installing it to your system unit.

Static electrical discharge can damage computer components without causing any signs of physical damage.

You must take extra care in handling the system board to ensure against electrostatic build-up.

Tips in Handling the System Board

1. To prevent electrostatic build-up, leave the board in its anti-static bag until you are ready to install it.

2. Wear an antistatic wriststrap.

3. Do all preparation work on a static-free surface with components facing up.

4. Hold the system board by its edges only. Be careful not to touch any of the components, contacts or connections, especially gold contacts on the board.

5. Avoid touching the pins or contacts on all modules and connectors. Hold modules and connectors by their ends.

Warning:

Electrostatic discharge (ESD) can damage your upgrade processor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some

G586OPC

ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the system chassis throughout any procedures requiring ESD protection.

Hardware Installation

Memory Installation

The G586OPC system board can support 2MB to

128MB of memory using 72-pin SIMMs (Single In-Line

Memory Module).

The SIMM sockets are divided into two banks on the system board. The G586OPC system board uses

256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and

8Mx36 SIMMs. Non-parity (x32) SIMMs can also be used if parity checking is turned off in CMOS setup.

You will need 2 or 4 pieces of SIMMs, depending on the amount of memory you intend to install.

To install the SIM modules, first populate Bank 0 and then Bank 1, or the system will not work.

The table on the next page summarizes the bank locations and modules needed for the corresponding memory sizes. Each bank consists of 2 SIMM sockets.

G586OPC

Installing Upgrade CPUs

The G586OPC is equipped with a 321-pin Zero

Insertion Force (ZIF) socket at location U26 of the system board. This socket is designed for easy removal of the old CPU and easy insertion of the upgrade CPU.

The socket allows you to carefully place the new CPU into its position. If you need to apply excessive force to insert the CPU, the installation is being done incorrectly.

Warning:

Open the socket only if actually installing a CPU. The warranty on the original CPU will be voided if the S/N seal is broken.

Do not change any factory CPU speed jumper settings.

You do not need to change any jumpers to properly install the 3.3V Pentium Upgrade Processor.

Before proceeding with the upgrade, take note of the following. The microprocessor and heat sink may be hot if the system has been running. To avoid the possibility of a burn, power the system off and let the processor and heat sink cool for 10 minutes.

The 321-pin ZIF socket consists of the four rows of pin holes on each side. To prevent improper OverDrive

Processor installation, the ZIF socket has a Plug/Keying mechanism. Several holes in the socket are plugged so

OverDrive Processors will go in only one way. If you cannot easily insert the OverDrive Processor, verify that pin 1 of the CPU is aligned with pin 1 of the socket. A warning note — be extremely careful to match pin 1 of the CPU with pin 1 of the socket. Only Intel's

OverDrive Processor is keyed to prevent improper placement in the ZIF socket. Other Intel CPUs, as well

42

PCI/ISA System Board as CPUs from other vendors, can be placed incorrectly and will be permanently damaged.

43

Zero Insertion Force (ZIF) Socket

To install an upgrade CPU, do the following.

1. Make sure the handle on the side of the ZIF socket is up. To raise the handle, push down, pull it out to the side a little and raise it as far as it will go. The top plate will slide back. Do not use screwdrivers or other tools to open the socket, or damage may occur to the system or socket. It may be necessary to initially apply a small amount of sideways force to free the handle from its retaining “tab.” Once clear of the “tab,” the handle will open relatively easily.

G586OPC

Lifting the Handle

2. Once the lever is completely up, remove the old

CPU by carefully lifting it straight out of the socket.

You are now ready to insert the new CPU.

Pin 1 of the ZIF Socket

44

PCI/ISA System Board

3. Position the CPU above the ZIF socket. Make sure pin 1 of the CPU is aligned with pin 1 of the socket.

Lower the chip until the pins are inserted properly in their corresponding holes. Remember that very little force is needed to install the CPU. If the CPU will not insert easily, verify pin 1 of the CPU is aligned with pin 1 of the socket. Applying too much pressure can damage the CPU or the socket.

45

Positioning the CPU Above the ZIF Socket

4. Push the handle down until the handle locks into place. 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. However, if the handle is not completely closed, damage to the CPU and/or system board may result.

G586OPC

Clearance Requirements

The 3.3V Pentium Upgrade Processor comes with a heat sink mounted on top. To maintain proper airflow once the upgrade is installed on the system board, the processor and sink require certain space clearances.

The clearance above 3.3V Pentium Upgrade Processor's fan/heat-sink must be at least 0.4 in. The clearance on at least 3 of 4 sides of the processor must be at least 0.2

in. The cables (for floppy drive, hard drive, CD-ROM, etc.) must be routed clear of the CPU and its airspace.

Fan Exhaust

The CPU must be kept cool by using a fan exhaust configuration in connection with the heatsink. The temperature of the air entering the fan/heatsink cannot exceed 45°C. The ambient or room temperature must be below 37°C (99°F) for a system installed with the 3.3V

Pentium Upgrade Processor.

In order to provide proper airflow to the CPU, all movable obstructions (power supply cables, cards, floppy disk cables) must be clear of the CPU heatsink/ fan component in accordance with the space clearance discussed in the CPU installation section of this manual.

Floppy Disk Drive Controller

The G586OPC system board has a built-in floppy disk controller that supports two standard floppy disk drives.

You can install any 720KB/1.2MB/1.44MB/2.88MB

floppy disk drives.

51

Connecting the Floppy Disk Cable

G586OPC

The Floppy Disk Connector on the

G586OPC System Board

Step 1

Install the 34-pin header connector into the floppy disk connector (J8) on the system board. The colored edge of the ribbon should be aligned to pin 1 of the J8 connector.

Step 2

Install the other 34-pin header connector(s) into the disk drive(s) with the colored edge of the daisy chained ribbon cable aligned to pin 1 of the drive edge connector(s). The end-most connector should be attached to the drive you want to be Drive A.

52

PCI/ISA System Board

IDE Hard Disk Interface

The G586OPC system board is equipped with two PCI

IDE shrouded headers that will interface four IDE

(Integrated Drive Electronics) hard disk drives.

Note:

Only IDE drives can be connected to the IDE interface.

Connecting the IDE Hard Disk Interface

To prevent improper IDE cable installation, each PCI

IDE shrouded header has a keying mechanism. The 40pin connector on the IDE cable can be placed into the header only if pin 1 of the connector is aligned with pin

1 of the header.

53

Note:

The IDE cable with a standard 40-pin connector can be installed in the PCI IDE shrouded header. Be extremely careful to match the colored edge of the ribbon with pin

1 of the header.

G586OPC

The IDE Hard Disk Connector on the System Board

Step 1

If you are connecting two hard drives, install the 40-pin connector of the IDE cable into the primary IDE shrouded header (1st IDE Connector). If you are adding a third or fourth IDE device, install the 40-pin connector of the other IDE cable into the secondary IDE shrouded header (2nd IDE Connector).

Step 2

Install the other 40-pin header connector(s) into the device with the colored edge of the ribbon cable aligned to pin 1 of the drive edge connector(s).

Note:

Refer to your disk drive user's manual for information about selecting proper drive switch settings.

54

PCI/ISA System Board

Adding a Second IDE Hard Drive

When using two IDE drives, one must be set as the master and the other as the slave. Follow the instructions provided by the drive manufacturer for setting the jumpers and/or switches on the drives. No changes are needed on the G586OPC system board when adding a second hard drive.

We recommend that the IDE hard drives be from the same manufacturer. In a few cases, drives from two manufacturers will not function properly when used together. The problem lies in the hard drives, not the

G586OPC system board.

Preparing an IDE Drive for Use

IDE disk drives are already low-level formatted, with any bad-track errors entered, when shipped by the drive manufacturer. Do not attempt to do a low-level format, or you may cause serious damage to the drive.

To use an IDE drive, you need to enter the drive type

(this information is provided by the drive manufacturer) into the system’s CMOS setup table. Then run FDISK and FORMAT provided with DOS.

Note:

Do not run FDISK and FORMAT programs on a drive that has already been formatted, or you will lose all programs and data stored on the drive.

55

G586OPC

Installing Expansion Cards

The G586OPC is equipped with three dedicated PCI and three dedicated ISA slots. One PCI slot and one ISA slot are shared. You can only install a card in one or the other of the shared slots at a time; you cannot install devices in both slots. Due to the size of the the optional synchronous pipeline burst cache module installed in the

160-pin cache module upgrade slot, the length of the card in PCI Slot 2 is limited. Refer to page 27 for limitations. The locations of the expansion slots are shown on the next page.

Note:

The BIOS needs to be configured for the PCI add-on cards installed in the PCI slots. Refer to the “PCI

Configuration Setup” chapter presented in the “Initial

Setup Program” section of the manual.

Be careful to avoid touching all connectors and pins on the board. Please refer to the handling instructions on pages 6-8 for proper handling techniques.

Step 6

Step 7

Insert the SIMMs into the SIMM banks on the

G586OPC. The quantity and location of the SIMMs is dependent upon the memory configuration and type of modules you intend to use.

Install the CPU. Be sure pin 1 of the CPU is aligned with pin 1 of the socket.

Step 8

Set the corresponding jumpers.

Step 9

Install the prepared G586OPC system board into the case and replace the screws.

Step 10

Reinstall all cards and connectors and replace the system unit cover. Reconnect all power cords and cables.

v Troubleshooting Checklist

If you experience difficulty with the G586OPC system board, please refer to the checklist below. If you still cannot isolate the problem, please contact your dealer.

1) Check the jumper settings to ensure that the jumpers are properly set. If in doubt, refer to the “Board

Configuration” section.

2) Verify that all SIM modules are seated securely into

the bank sockets.

3) Make sure the SIM modules are in the correct locations.

4) Check that all populated memory banks are filled with valid size SIM modules.

5) If your board fails to function, place the board on a flat surface and seat all socketed components (gently press each component into the socket).

6) If you made changes to the BIOS settings, re-enter setup and load the BIOS defaults.
