Hardware Installation
This chapter summarizes the steps to install the 586IVX 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. Refer to the
System Memory section for the number and type of memory 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 also 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 ideal location, unpack the 586IVX system board carefully.
Handling the System Board
It is quite easy to inadvertently damage your system board even before installing it in 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.
9
Static Electricity Precautions
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 wrist strap.
3. Do all preparation work on a static-free surface with the system board 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 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 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.
Installing the System Board
If you are installing the 586IVX system board, the following outlines the basic installation steps. Before installing the system board into your system unit, you should prepare the tools you will need.
You will need:
• One medium size, flat-bladed screwdriver

notch key
1. Position the SIMM above the socket with the “notch” in the module aligned with the “key” on the socket.
2. Seat the module at a 45° angle into the bank. Make sure it is completely seated. Tilt the module upright until it locks in place in the socket.
Cache Memory
The 586IVX system board can support 256KB pipeline burst, direct map write-back cache SRAM. Your system board may come with 256KB cache mounted at locations U11 and U17 of the system board.
16
CPU Installation
The 586IVX allows for easy installation of CPUs. Make sure all jumpers are set correctly before applying power or you may damage the CPU or system board. Use a needle-nosed plier to move the jumpers if necessary.
Jumpers JP10, JP11 and JP12 are used to set the external bus clock of your processor. Refer to the following pages for the external bus clock that corresponds to your processor and set these jumpers accordingly. The clock generator will determine the external bus clock that must be sent to the processor through these settings.
Jumper JP5 is used to set the frequency ratio of your processor. Refer to the following pages for the frequency ratio that corresponds to your processor and set this jumper accordingly.
After setting these jumpers, an Intel processor will multiply the external bus clock by the frequency ratio to become the internal clock speed. Internal clock speed is the commonly used speed of Intel processors in the market and is the actual operating clock of the processor (external bus clock x frequency ratio = internal clock speed).
Cyrix and AMD processors use the P-rating system which is the overall
CPU performance rating. Under the system, these processors slightly out-
Jumpers JP2, JP3, JP4 and JP7 are used to set the voltage of your processor. Make sure these jumpers are set correctly, otherwise your system will hang.

The 586IVX is equipped with a 321-pin Zero Insertion Force (ZIF) socket at location U29 of the system board. Refer to page 12 for the location of the ZIF socket. This socket is designed for easy removal of an old CPU and easy insertion of an upgrade CPU. The ZIF socket allows you to carefully place the new CPU into its position. If you need to apply excessive force to insert the CPU, you are not installing the
CPU correctly.
Warning:
Open the socket only if you are actually installing a CPU. The warranty on the original CPU will be voided if the S/N seal is broken. Before proceeding with the upgrade, take note of the following. The microprocessor and heatsink 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 heatsink cool for 20 minutes.
The 321-pin ZIF socket consists of five rows of pin holes on each side.
To prevent improper CPU installation, the ZIF socket has a Plug/Keying mechanism. Several holes in the socket are plugged so that the CPU will go in only one way. If you cannot easily insert the CPU, verify that pin 1 of the CPU is aligned with pin 1 of the socket.
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 it down, slightly pull it out to the side, then raise it as far as it will go. It may be necessary to initially apply a small
21
amount of sideways force to free the handle from its retaining “tab”.
Once clear of the “tab”, the handle will open relatively easily. The top plate will slide back. Do not use screwdrivers or other tools to open the socket, or you may damage the system or socket.
Handle
Lifting the Handle
2. Once the lever is completely up, remove the old CPU carefully by lifting it straight out of the socket. You are now ready to insert the new CPU.
22
Pin 1
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 is not easily inserted, verify whether or not pin 1 of the CPU is aligned with pin 1 of the socket. Applying too much pressure can damage the CPU or the socket.
Pin 1
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 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.
Installing A Fan/Heatsink
You must choose a fan/heatsink suitable for the processor installed on your system board. Position the fan/heatsink on the CPU such that the air from the side of the fan/heatsink will flow across the heat regulators on the system board. See the figure below.
Clearance Requirements
Your CPU comes with a heatsink mounted on top. To maintain proper airflow once the upgrade is installed on the system board, the CPU and heatsink require certain space clearances. The clearance above the
CPU’s fan/heatsink must be at least 0.4 inches. The clearance on at
23
least 3 of 4 sides of the processor and heatsink must be at least 0.2
inches. All 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 with heatsink. The temperature of the air entering the fan/heatsink cannot exceed 45 o C (113 o F).
The ambient or room temperature must be below 37 o C (99 o F).
Jumper Settings for CMOS Clear

The 586IVX is equipped with two serial ports at locations CN5 (COM 2) and CN6 (COM 1) of the system board. These built-in serial ports are
RS-232C asynchronous communication ports with 16C550A-compatible
UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices.
Parallel Port
The 586IVX system board has a standard printer port (CN7) for interfacing your PC to a parallel printer. It supports SPP, ECP and EPP modes.
You can set the port’s mode in the Integrated Peripherals setup of the
Award BIOS (Refer to Chapter 3).

Floppy Disk Drive Controller
The 586IVX system board is equipped with a shrouded floppy disk header that supports two standard floppy disk drives. You can install any 360KB, 720KB, 1.2MB, 1.44MB, or 2.88MB floppy disk drives. To prevent improper floppy cable installation, the shrouded floppy disk header has a keying mechanism. The 34-pin connector on the floppy cable can be placed into the header only if pin 1 of the connector is aligned with pin 1 of the header.
Connecting the Floppy Disk Cable
1. Install the 34-pin header connector into the shrouded floppy disk header (J10) on the system board. The colored edge of the ribbon should be aligned with pin 1 of connector J10.
2. Install the other 34-pin header connector(s) into the disk drive(s).
Align the colored edge of the daisy chained ribbon cable with pin 1 of the drive edge connector(s). The end-most connector should be attached to the drive you want to designate as Drive A.
IDE Hard Disk Interface
The 586IVX system board is equipped with two shrouded PCI IDE headers that will interface four Enhanced IDE (Integrated Drive Electronics) hard disk drives.
Note:
Only Enhanced IDE hard drives or ATAPI CD-ROMs can be connected to the IDE interface.
Connecting the IDE Hard Disk Interface
To prevent improper IDE cable installation, each shrouded PCI IDE header has a keying mechanism. The 40-pin 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.
27
28
Header
Note:
An IDE cable with a standard 40-pin connector (without the keying mechanism) can be installed in the shrouded PCI IDE header. Be extremely careful to match the colored edge of the ribbon with pin 1 of the header.
Connecting the Hard Disk Cable
1. If you are connecting two hard drives, install the 40-pin connector of the IDE cable into the primary shrouded IDE header (connector
J11). If you are adding a third or fourth IDE device, install the 40pin connector of the other IDE cable into the secondary shrouded
IDE header (connector J12).
2. Install the other 40-pin header connector(s) into the device with the colored edge of the ribbon cable aligned with 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.
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.
We recommend that you use Enhanced IDE hard drives from the same manufacturer. In a few cases, drives from two different manufacturers will not function properly when used together. The problem lies in the hard drives, not the 586IVX 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. You may also use the IDE HDD Auto Detection function which will allow the BIOS to auto detect your hard drive type. Refer to the IDE HDD Auto Detection section for details.
Warning:
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.
Using 586IVX with CD-ROM Drives
If you encountered problems while using an ATAPI CD-ROM drive that is set in Master mode, please set the CD-ROM drive to Slave mode.
Some ATAPI CD-ROMs may not be recognized and cannot be used if incorrectly set in Master mode.
Universal Serial Bus Connectors
The 586IVX system board is equipped with two USB ports on locations
J2 and J4 on the system board. USB allows data exchange between your computer and a wide range of simultaneously accessible peripherals. Make sure “USB Controller” in the Integrated Peripherals setup of the Award BIOS is set to Enabled.
29
Installing Expansion Cards
The 586IVX system board is equipped with 3 dedicated PCI slots, 3 dedicated 16-bit ISA slots and 1 shared PCI/ISA slot. All PCI slots are bus masters. Refer to page 12 for the locations of the expansion slots.

Down & Resume Events)
These are I/O events whose occurrence can prevent the system from entering a power saving mode or can awaken the system from such a mode. In effect, the system remains alert for anything which occurs to a device which is configured as enabled, even when the system is in a power saving mode.
When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service.
PNP/PCI Configuration
This section describes configuring the PCI bus system. It covers some very technical items, and it is strongly recommended that only experienced users make any changes to the default settings.

Standard CMOS Setup.
Hard Drive Mode
The system board supports three HDD modes: Normal, LBA and Large.
If your hard disk drive does not support LBA mode, the “LBA” option will not be displayed. If your HDD has 1024 or fewer cylinders, the “Large” option will not be displayed. If your hard drive is larger than 2.1GB, be sure that your operating system supports it or you may need to create separate partitions.
Normal Mode
Normal mode is the generic access mode in which neither the BIOS nor the IDE controller will make any transformations during hard-drive access.
The maximum number of cylinders, heads and sectors for Normal mode are 1024, 16 and 63, respectively.
no. Cylinders x no. Heads x no. Sectors x bytes per sector
528 megabytes
(1024)
( 16)
( 63)
( 512)
If you set your HDD to Normal mode, the maximum accessible HDD will be 528 megabytes even though the physical size of the HDD may be greater than that.
LBA (Logical Block Addressing) Mode
LBA mode is a HDD accessing method to overcome the 528 megabyte limitation. The number of cylinders, heads and sectors shown on the screen may not be the actual number for the HDD.
During HDD accessing, the IDE controller will transform the logical address described by the sector, head and cylinder number into its own physical address inside the HDD.
The maximum HDD size supported by the LBA mode is 8.4 gigabytes. It is obtained by the following formula.
no. Cylinders x no. Heads x no. Sectors x bytes per sector
8.4 gigabytes
(1024)
( 255)
( 63)
( 512)
Large Mode
Large mode is the extended HDD access mode supported by the system board. Some IDE HDDs have more than 1024 cylinders without
LBA support (in some cases, you may not want the LBA mode). This system board provides another alternative to support these kinds of
HDDs.
The BIOS tells the operating system that the number of cylinders is half the actual number and that the number of heads is double the actual number. During disk access, the reverse conversion is done by the
INT13h routine.

Note:
To support LBA or Large mode, address translation software is included in the Award BIOS HDD Service Routine (INT13h). If you are running an operating system that bypasses the BIOS INT13 Service Routine,
LBA and Large Mode may fail.

Desktop Management Interface (DMI)
The 586IVX system board comes with a DMI built into the BIOS. DMI, along with the appropriately networked software, is designed to make inventory, maintenance and troubleshooting of computer systems easier. With DMI, a network administrator or MIS engineer can remotely access some information about a particular computer system without physically going to it. Quite often a service call may be unnecessary as the problem can be solved remotely.
The DMI utility in the BIOS automatically records various information about your system configuration. Information about the type and speed of CPU, type and amount of memory for each memory slot, BIOS revision level, types of add-in PCI boards and components, certain revision numbers of hardware installed, etc. are automatically detected and stored in the DMI pool, which is a part of the system board's Plug and
53
Play BIOS. Additional information, such as ISA based peripherals, which may not be automatically detected, can be manually recorded in the DMI pool by using the Add DMI menu. The DMI pool data is then verified or updated whenever the system hardware or setup is altered.
Running the DMI Utility
To run the DMI utility, type: DMICFG.EXE. You can download this utility from http://www.dfi.com.tw - BIOS & DRIVERS section or ftp.dfiusa.com -
/pub/DMI directory.
The DMI utility must run in real mode with at least 180K of base memory. Memory managers like HIMEM.SYS (required by Windows) must not be installed. To do this, boot up from a system diskette without the AUTOEXEC.BAT and CONFIG.SYS files. “REM” HIMEM.SYS in the
CONFIG.SYS or press <F5> during bootup to bypass your
AUTOEXEC.BAT and CONFIG.SYS files.

Chapter 4
Troubleshooting Checklist
This chapter of the manual is designed to help you with problems that you may encounter with your personal computer. To efficiently troubleshoot your system, treat each problem individually. This is to ensure an accurate diagnosis of the problem in case a problem has multiple causes.
Some of the most common things to check when you encounter problems while using your system are listed below.
1. The power switch of each peripheral device is turned on.
2. All cables and power cords are tightly connected.
3. The electrical outlet to which your peripheral devices are connected is working. Test the outlet by plugging in a lamp or other electrical device.
4. The monitor is turned on.
6. All add-in boards in the expansion slots are seated securely.
7. Any add-in board you have installed is designed for your system and is set up correctly.
Monitor/Display
If the display screen remains dark after the system is turned on: to the monitor and the other end is plugged into a working AC outlet.
If necessary, try another outlet.
3. Check that the video input cable is properly attached to the monitor
4. Adjust the brightness of the display by turning the monitor’s brightness control knob.

Hard Drive
Hard disk failure.
1. Make sure the correct drive type for the hard disk drive has been entered in the BIOS.
2. If the system is configured with two hard drives, make sure the bootable (first) hard drive is configured as Master and the second hard drive is configured as Slave.
Excessively long formatting period.
1. If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem.
Parallel Port
The parallel printer doesn’t respond when you try to print.
1. Make sure that your printer is turned on and that the printer is online.
2. Make sure your software is configured for the right type of printer attached.
configured correctly.
4. Verify that the attached device works by attaching it to a parallel port that is working and configured correctly. If it works, the printer can be assumed to be in good condition. If the printer remains inoperative, replace the printer cable and try again.
Serial Port
The serial device (modem, printer) doesn’t output anything or is outputting garbled characters.
1. Make sure that the serial device’s power is turned on and that the device is on-line.
2. Verify that the device is plugged into the correct serial port on the rear of the computer.
3. Verify that the attached serial device works by attaching it to a serial port that is working and configured correctly. If the serial device does not work, either the cable or the serial device has a problem. If the serial device works, the problem may be due to the onboard I/O or the address setting.
4. Make sure the COM port settings and I/O address are configured correctly.
Keyboard
Nothing happens when a key on the keyboard was pressed.
1. Make sure the keyboard is properly connected.
2. Make sure there are no objects resting on the keyboard and that no keys are pressed during the booting process.
System Board
1. Make sure the add-in card is seated securely in the expansion slot.
If the add-in card is loose, power off the system, re-install the card and power up the system.
2. Check the jumper settings to ensure that the jumpers are properly set.
3. Verify that all SIMMs are seated securely into the SIMM sockets.
4. Make sure the SIMMs are in the correct locations.
5. If the 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.
