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.
System Memory
The system board is equipped with two 168-pin DIMM (Dual In-line Memory
Module) sockets that support VCM or PC SDRAM DIMM. PC SDRAM (Synchronous Dynamic Random Access Memory) uses 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.
Refer to Chapter 1 (System Memory section)
for detailed specification of the memory supported by the system board.
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.
1. Pull the “tabs,” located at the end of
the socket, to the side
2. Position the DIMM above the socket with the “notches” in the module
aligned with the “keys” on the socket.
3. Seat the module vertically into the socket. Make sure it is completely
seated. The tabs will hold the DIMM in place.

Advanced Chipset Features
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 neces-
sary. 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.
DRAM Timing by SPD
Enabled The EEPROM on a PC SDRAM DIMM that has SPD (Serial
Presence Detect) data structure stores information about the
module such as the memory type, memory size, memory
speed, etc. When this field is enabled, the system will run
according to the information in the EEPROM.
Disabled It allows you to configure the 2 fields that follow (SDRAM
Cycle Length and DRAM Clock). The system will run
according to the settings in these fields.
SDRAM Cycle Length
This field is used to set the clock cycle for the CAS latency.
DRAM Clock
This field allows you to set the DRAM clock.

System BIOS Cacheable
When this field 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 RAM Cacheable
When enabled, it allows the video RAM to be cacheable thus providing better
video performance. If your graphics card does not support his function, leave
this field in its default setting - Disabled.
I/O Recovery Time
Selecting Enabled will allow additional time for I/O devices to respond to the
system. However, if your I/O devices are capable of fast I/O, select Disabled
to speed up system operation.
Frame Buffer Size
The options are 2M, 4M, and 8M.
OnChip USB
This field is used to enable or disable the onboard USB controller supported
by the chipset. If you are using a USB peripheral, make sure to set this field to
Enabled.
USB Keyboard Support
This field will appear only if the “OnChip USB” field is set to Enabled. By
default, USB Keyboard Support is Disabled. However; if you are using a USB
keyboard under DOS, make sure to enable this function.
PCI Delay 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.

Integrated Peripherals
The screen above lists all the fields available in the Integrated Peripherals
submenu for you to reference. In the actual CMOS setup, you must scroll to
view all of the fields. The settings on the screen are for reference only — your
version may not be identical to this one.
On-Chip Primary IDE and On-Chip Secondary IDE
These fields allow you to enable or disable the primary and secondary IDE
controller. The default is Enabled. Select Disabled if you want to add a different hard drive controller.
IDE Prefetch Mode
This allows data and addresses to be stored in the internal buffer of the chip,
thus reducing access time. Enable this field to achieve better performance.
IDE Primary Master/Slave PIO and IDE Secondary Master/Slave PIO
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. Your system supports five modes, 0
(default) to 4, which primarily differ in timing. When Auto is selected, the BIOS
will select the best available mode after checking your drive.

CPU Fan Protection
The CPU Fan Protection function, when enabled, has the capability of monitoring the CPU fan during system boot-up and will automatically power-off the
system once it has detected that the CPU fan did not rotate. Set this field to
disabled if you are not using this function. Refer to “CPU Fan Connector with
CPU Fan Protection Function” in chapter 2 for more information.
CPU Temp. Prot. Function and CPU Temp. Prot. Alarm
The CPU Temperature Protection function has the capability of monitoring the
CPU’s temperature during system boot-up. To use this function, set the “CPU
Temp. Prot. Function” field to Enabled, then select the desired CPU temperature limit in the “CPU Temp. Prot. Alarm” field. Once the system has detected
that the CPU’s temperature exceeded the limit, 5 warning beeps will sound
and at the same time, a warning message will appear on the boot-up screen
instructing you to press <Del> in order to enter the man menu of the BIOS. If
you did not press <Del>, the system will automatically power-off after the 5
warning beeps. You may either:
1. Press <Del> then enter a new CPU temperature limit;
or
2. Allow the system to power-off after the 5 warning beeps then check
whether the heatsink and fan are mounted properly onto the CPU
because high CPU temperature may be due to incorrect fan/heatsink
installation. Now restart the system. If the same problem persists, it
may be that the CPU fan is damaged or it is not rotating properly. Try
replacing it with a new fan. If it is due to other contributing factors that
resulted in high CPU temperature, you may need to set a lower CPU
temperature limit.
CPU Temperature References
When you power-up a system, the BIOS message appears on the
screen and the memory count begins. After the memory test, the
CPU temperature range is normally between 32° C and 35° C. When
you run an operating system then tried to reboot the system, the CPU
temperature range at this time is between 40° C and 45° C. These
temperature references serve as a guide when you select the CPU
temperature limit.

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 writeprotected.
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.
Hard Drive
Hard disk failure: Make sure the correct drive type for the hard disk drive has
been entered in the BIOS.
Excessively long formatting period: 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.
Serial Port
The serial device 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 confgured 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 onbaord I/O or the
address setting.
4. Make sure the COM settings and I/O address are configured correctly.
