Hardware Installation  
2.2 System Memory  
The 168-pin DIMM (Dual In-  
line Memory Module) sockets  
support PC SDRAM DIMM,  
3.3V.  
(Synchronous  
PC  
SDRAM  
Dynamic  
Random Access Memory) is a  
fast memory interface  
technology that includes  
using 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.  
The system board supports the ECC (Error Checking and  
Correction) function. To use this function, you must install DIMM  
that supports parity. That is, DIMM that typically has 9 memory  
chips per side. This kind of module has 8 standard memory chips  
and a parity chip. DIMM with no parity has 8 standard memory  
chips only. Refer to chapter 1 (System Memory section) for  
detailed specification of the memory supported by your system  
board.  
2.2.1 Installing the DIM Module  
A DIM module simply snaps into a DIMM socket on the system  
board. Pin 1 of the DIM module must correspond with Pin 1 of the  
socket.

two hard drives, install  
the 40-pin connector  
of the IDE cable into  
the primary shrouded  
IDE header (connector  
J8). If you are adding a  
third or fourth IDE  
device, install the 40-  
pin connector of the  
other IDE cable into  
the secondary  
shrouded IDE header (connector J7).  
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 or ATA-2, ATA-3 and  
Ultra DMA hard drives be 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 system board.  
Important:  
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

Virus Warning  
This category protects the boot sector and partition table of your hard  
disk drive. When this item is enabled, the Award BIOS will monitor the  
boot sector and partition table of the hard disk drive. If an attempt  
is made to write to the boot sector or partition table of the hard disk  
drive, the BIOS will halt the system and an error message will appear.  
After seeing the error message, if necessary, you will be able to run  
an anti-virus program to locate and remove the problem before any  
damage is done.  
Many disk diagnostic programs which attempt to access the boot  
sector table will cause the warning message to appear. If you are  
running such a program, we recommend that you first disable this  
category. Also, disable this category if you are installing or running  
certain operating systems like Windows® 95/98 or the operating  
system may not install nor work.

Award BIOS Setup Utility  
CPU L1 Cache and CPU L2 Cache  
These categories speed up the memory access. The default value is  
enabled. Enable the External Cache for better performance.  
CPU L2 Cache ECC Checking  
Intel CeleronTM processors come with built-in Level 2 cache. By  
default, ECC is enabled to check the Level 2 cache. If you are not  
using this function, set this field to Disabled.  
Quick Power On Self Test  
This category speeds up Power On Self Test (POST) after you power  
on your system. When Enabled, the BIOS will shorten or skip some  
check items during POST.  
Boot Sequence  
This category determines which drive to search first for the disk  
operating system. The default is A, C, SCSI. The options are:  
A, C, SCSI;  
D, A, SCSI;  
SCSI, C, A;  
C, A, SCSI;  
E, A, SCSI;  
C only;  
C, CDROM, A;  
F, A, SCSI;

Swap Floppy Drive  
When this option is enabled and the system is booting from the floppy  
drive, the system will boot from drive B instead of drive A. When this  
option is disabled and the system is booting from the floppy drive, the  
system will boot from drive A. You must have two floppy drives to  
use this function.  
Boot Up Floppy Seek  
When enabled, the BIOS will check whether the floppy disk drive installed  
is 40 or 80 tracks. Note that the BIOS cannot distinguish between 720K,  
1.2M, 1.44M and 2.88M drive types as they are all 80 tracks. When  
disabled, the BIOS will not search for the type of floppy disk drive by  
track number. Note that there will not be any warning message if the drive  
installed is 360KB.

Boot Up NumLock Status  
This allows you to determine the default state of the numeric keypad.  
By default, the system boots up with NumLock on wherein the function  
of the numeric keypad is the number keys. When set to Off, the  
function of the numeric keypad is the arrow keys.  
Typematic Rate Setting  
When disabled, continually holding down a key on your keyboard will  
cause the BIOS to report that the key is down. When the typematic  
rate is enabled, the BIOS will not only report that the key is down,  
but will first wait for a moment, and, if the key is still down, it will begin  
to report that the key has been depressed repeatedly. For example,  
you would use such a feature to accelerate cursor movements with  
the arrow keys.  
Typematic Rate (Chars/Sec)  
This selection allows you to select the rate at which the keys are  
accelerated.  
Typematic Delay (Msec)  
This selection allows you to select the delay between when the key  
was first depressed and when the acceleration begins.

Load Fail-Safe Settings  
Load Optimal Settings  
The settings on the screen are for reference only. Your version may not be  
identical to this one.  
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. It also  
coordinates communications between the conventional ISA bus  
and the PCI bus. 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 RAS-to-CAS Delay  
This field allows you to insert a timing delay between the CAS and  
RAS strobe signals, used when DRAM is written to, read from, or  
refreshed. This field applies only when synchronous DRAM is  
installed in the system.  
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.  
38  
 
3
Award BIOS Setup Utility  
SDRAM CAS Latency Time  
The default setting is 3 which is 3 clock cycles for the CAS latency.  
DRAM Data Integrity Mode  
The ECC (Error Checking and Correction) function is supported only  
in x72 (72-bit) PC SDRAM DIMMs. If you are using x64 (64-bit) PC  
SDRAM DIMMs, set this field to Non-ECC.  
Non-ECC Uses x64 PC SDRAM DIMM.  
ECC This option allows the system to recover from memory  
failure. It detects single-bit and multiple-bit errors, then  
automatically corrects single-bit error.  
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.  
Video RAM Cacheable  
When enabled, it allows the video RAM to be cacheable thus  
providing better video performance. If your graphics card does not  
support this function, leave this field in its default setting - Disabled.  
8 Bit I/O Recovery Time and 16 Bit I/O Recovery Time  
The recovery time is the length of time, measured in SYSCLK, which  
the system will delay after the completion of an input/output  
request. This delay takes place because the CPU is operating so  
much faster than the input/output bus that the CPU must be  
delayed to allow for the completion of the I/O. This item allows you  
to determine the recovery time allowed for 8-bit I/O or 16-bit I/O.  
39

Award BIOS Setup Utility  
Memory Hole At 15M-16M  
In order to improve system performance, certain space in memory  
can be reserved for ISA cards. This memory must be mapped into  
the memory space below 16MB. When enabled, the CPU assumes  
the 15-16MB memory range is allocated to the hidden ISA address  
range instead of the actual system DRAM. When disabled, the CPU  
assumes the 15-16MB address range actually contains DRAM  
memory. If more than 16MB of system memory is installed, this  
option must be disabled to provide contiguous system memory.  
PCI 2.1 Compliance  
By default, this field is Disabled. However, if you encounter problems  
with your PCI card, try setting this field to Enabled. It may be that  
your card is PCI 2.1 compliant.  
AGP Aperture Size (MB)  
This field is relevant to the memory-mapped graphics data of the  
AGP card installed in your system. Leave this in its default setting,  
which is 64MB.  
CPU/PCI Clock (MHz)  
This field is used to select the external system bus clock of your  
processor. The options are Default, 66.8/33.4, 75/37.5, 83.3/  
41.65, 100.3/33.4, 103/34.33, 105/35, 110/36.67, 112/37.33,  
115/38.33, 120/40, 124/31, 124/41.33, 133/33.25, 133/44.33,  
140/35 and 150/37.5. When selecting the external bus clock of  
your 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. If you selected an option other  
than “Default” and is unable to boot up the system, there are 2  
methods of going back to its default setting.  
Method 1:  
Clear the CMOS data by following the procedure in section 2.5  
(chapter 2) of this manual. All fields in the BIOS Setup will  
automatically be set to its default settings.  
40  
 
3
Award BIOS Setup Utility  
Method 2:  
Press the <Insert> key and power button simultaneously, then  
release the power button first. You must keep-on pressing the  
<Insert> 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  
“Chipset Features Setup” and set the “CPU/PCI Clock (MHz)” field  
to “Default” or an appropriate clock frequency.  
Note:  
When using a 66MHz FSB processor, the AGP clock is  
similar to the CPU’s external bus clock. When using a  
100MHz FSB processor, the AGP clock is 2/3 of the CPU’s  
external bus clock.  
Spread Spectrum  
Leave this field in its default setting - Disabled. Do not alter this  
setting unless advised by an engineer or technician.  
3.1.4 Power Management Setup  
The Power Management Setup allows you to configure your system to  
most effectively save energy. If you like to use the soft power down

This category is used to set an IRQ channel (IRQ 3, 4, 5, 7, 9, 10 or  
11) for the external modem installed in your system. However, if the  
“Resume on Ring” or “Resume on LAN” field is disabled, the BIOS will  
mask the IRQ assigned for the modem. This is to prevent the modem  
or LAN from waking up the system when it is in the Suspend mode.  
Standby Mode  
This is user configurable only when the Power Management category  
is set to User Defined. When enabled and after the set time of  
system inactivity, video will be shut off while all other devices still  
operate at full speed.  
Suspend Mode  
This is user configurable only when the Power Management category  
is set to User Defined. When enabled and after the set time of system  
inactivity, the CPU and onboard peripherals will be shut off.  
HDD Power Down  
This is user configurable only when the Power Management category  
is set to User Defined. When enabled and after the set time of system  
inactivity, the hard disk drive will be powered down while all other  
devices remain active.  
VGA Active Monitor  
Enabled When the system enters the Suspend mode, it will check  
the status of the VGA. If the VGA is active, it will not turn  
the screen off. If the VGA is inactive, it will turn the screen  
off.

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 part 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.  
4.1.1 Running the DMI Utility  
To run the DMI utility, type: DMICFG.EXE.  
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.

indicates that a video error has occured and the BIOS cannot  
initialize the video screen to display any additional information. This  
beep code consists of a single long beep followed by three short  
beeps. The other code indicates that a DRAM error has occured.  
This beep code consists of a single long beep.  
A.2 Error Messages  
One or more of the following messages may be displayed if the  
BIOS detects an error during the POST. This list indicates the error  
messages for all Awards BIOSes:  
CMOS BATTERY HAS FAILED  
The CMOS battery is no longer functional. It should be replaced.

AppendixB-Troubleshooting  
B.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.  
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.  
61

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.  
Floppy Drive  
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.
