Hardware Installation

Warning:

Electrostatic discharge (ESD) can damage your system board,
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.

2.2 System Memory

The system board is equipped
with two 168-pin DIMM (Dual
In-line Memory Module) sockets
that support unbuffered PC-100
SDRAM DIMM. PC SDRAM
(Synchronous Dynamic Random
Access Memory) is a fast
memory interface technology that
uses the clock on the chip to
synchronize with the CPU clock
so that the timing of the
memory chips and the timing of
the CPU are synchronized. This saves time during transmission of
data, subsequently increasing system performance.

2

The onboard VGA shares 1MB of the system memory. This is fixed
regardless of the size of the system memory.

Aside from the 1MB shared memory, it also uses the Dynamic Video
Memory Technology (DVMT). DVMT freely changes in size because
graphics memory is allocated from the system memory according to
current needs.

Refer to chapter 1 for the type of memory supported by the
system board.

This section gives you functions to configure the system based on
the specific features of the chipset. The chipset manages bus speeds
and access to system memory resources. These items should not

be altered unless necessary. The default settings have been chosen

because they provide the best operating conditions for your system.
The only time you might consider making any changes would be if
you discovered some incompatibility or that data was being lost
while using your system.

SDRAM CAS Latency Time

The default setting is 3 which is 3 clock cycles for the CAS latency.

SDRAM Cycle Time Tras/Trc

This field selects the number of SCLKs for an access cycle. The
default is 6/8.

SDRAM RAS-to-CAS Delay

This field allows you to insert a timing delay between the CAS and

Award BIOS Setup Utility

SDRAM RAS Precharge Time

If there is insufficient number of cycles for the RAS to accumulate its
charge before DRAM refresh, the refresh may be incomplete and the
DRAM may fail to retain data.

System BIOS Cacheable

When this option is enabled, accesses to the system BIOS ROM
addressed at F0000H-FFFFFH are cached, provided that the cache
controller is enabled. The larger the range of the Cache RAM, the
higher the efficiency of the system.

Video BIOS Cacheable

As with caching the system BIOS, enabling the Video BIOS cache will
allow access to video BIOS addresssed at C0000H to C7FFFH to
be cached, if the cache controller is also enabled. The larger the range
of the Cache RAM, the faster the video performance.

Delayed Transaction

When enabled, this function frees up the PCI bus for other PCI
masters during the PCI-to-ISA transactions. This allows PCI and ISA
buses to be used more efficiently and prevents degradation of
performance on the PCI bus when ISA accesses are made.

CPU Clock Ratio

This field is used to select the frequency ratio of the processor.

Important:

 The frequency ratio of some processors may have been

locked by the manufacturer. If you are using this kind of
processor, setting an extended ratio for the processor will
have no effect. The system will instead use its factory
default ratio.

 The frequency ratio of processors greater than 8x has been

locked by the manufacturer and will no longer have the
flexibility of using extended ratios. Therefore, the system will
use the processors factory default ratio.

CPU/PCI Clock (MHz)

This field is used to select the external system bus clock of the
processor. The PCI clock will at the same time appear next to the
external bus clock selected. For example, if you selected 66.8/33.4,

66.8MHz is the external bus clock and 33.4MHz is the PCI clock.
Regardless of the type of processor used, the default setting is
Default. Under this setting, the system will run according to the
processors clock frequency.

69

3

Award BIOS Setup Utility

Important:

Selecting an external bus clock other than 66MHz, 100MHz or
133MHz may result to the processors or systems instability
and are not guaranteed to provide better system performance.

If, in the "CPU Clock Ratio" or "CPU/PCI Clock (MHz)" field, you
selected an option other than the default setting and is unable to
boot up the system, there are 2 methods of booting up the system
and going back to its default setting.

Method 1:
Clear the CMOS data by setting JP7 to 2-3 On. All fields in the
BIOS Setup will automatically be set to their default settings.

Method 2:
Press the <Insert> key and power button simultaneously, then
release the power button first. Keep-on pressing the <Inser t> key
until the power-on screen appears. This will allow the system to boot
according to the FSB of the processor. Now press the <Del> key
to enter the Award BIOS setup utility. Select CPU Frequency
Control and set the "CPU Clock Ratio" or CPU/PCI Clock (MHz)
field to its default setting or an appropriate bus clock or frequency
ratio.

70

Note:

 Use a PS/2 or AT (requires a DIN to mini DIN adapter)

keyboard for method 2.

 When using a 66MHz FSB processor, the system memory

clock is 3/2 of the CPUs external bus clock and the PCI
clock is 1/2 of the CPUs external bus clock.

 When using a 100MHz FSB processor, the system memory

clock is the same as the CPUs external bus clock and the
PCI clock is 1/3 of the CPUs external bus clock.

 When using a 133MHz FSB processor, the system memory

clock is 3/4 of the CPUs external bus clock and the PCI
clock is 1/4 of the CPUs external bus clock.

Leave this field in its default setting. Do not alter this setting unless
advised by an engineer or technician.

4.1 Desktop Management Interface (DMI)

The 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 par t of the system board's
Plug and 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.

74

4.1.1 Running the DMI Utility

To run the DMI utility, type: DMICFG.EXE. You can download this utility
from ftp.dfiusa.com - /utilities/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. You may do this by using one of the 3 methods
listed below.

1. Boot up from a system diskette without the AUTOEXEC.BAT and
CONFIG.SYS files,

2. REM HIMEM.SYS in the CONFIG.SYS, or

3. Press <F5> during bootup to bypass your AUTOEXEC.BAT and
CONFIG.SYS files.

Troubleshooting

Appendix C - Troubleshooting

C.1 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.

5. The displays brightness and contrast controls are adjusted
properly.

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.

C

Monitor/Display

If the display screen remains dark after the system is turned on:

1. Make sure that the monitors power switch is on.

2. Check that one end of the monitors power cord is properly
attached 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 and the systems display adapter.

4. Adjust the brightness of the display by turning the monitors
brightness control knob.

87

C

Troubleshooting

The picture seems to be constantly moving.

1. The monitor has lost its vertical sync. Adjust the monitors vertical
sync.

2. Move away any objects, such as another monitor or fan, that
may be creating a magnetic field around the display.

3. Make sure your video cards output frequencies are supported
by this monitor.

The screen seems to be constantly wavering.

1. If the monitor is close to another monitor, the adjacent monitor
may need to be turned off. Fluorescent lights adjacent to the
monitor may also cause screen wavering.

Power Supply

When the computer is turned on, nothing happens.

1. Check that one end of the AC power cord is plugged into a live
outlet and the other end properly plugged into the back of the
system.

2. Make sure that the voltage selection switch on the back panel is
set for the correct type of voltage you are using.

3. The power cord may have a short or open. Inspect the cord
and install a new one if necessary.

The computer cannot access the floppy drive.

1. The floppy diskette may not be formatted. Format the diskette
and try again.

2. The diskette may be write-protected. Use a diskette that is not
write-protected.

3. You may be writing to the wrong drive. Check the path
statement to make sure you are writing to the targeted drive.

4. There is not enough space left on the diskette. Use another
diskette with adequate storage space.

Troubleshooting

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. The master hard drive
must have an active/bootable partition.

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. However, if your
hard drive has a large capacity, it will take a longer time to
format.

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
on-line.

2. Make sure your software is configured for the right type of
printer attached.

3. Verify that the onboard LPT ports I/O address and IRQ settings
are 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.

Troubleshooting

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 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 memory modules are seated securely into the
memory sockets.

4. Make sure the memory modules 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.
