The mainboard has a 32-bit Enhanced IDE and Ultra DMA 133/100 controller
that provides PIO mode 0~4, Bus Master, and Ultra DMA 133/100 functions.
You can connect up to four hard disk drives, CD-ROM and other devices.
The primary hard drive should always be connected to IDE1 as the master
drive. Both IDE drives can connect to a master and a slave drive.

JUMPERS
The mainboard provides jumpers for setting some mainboard functions. This
section will explain how to change the settings of the mainboard functions
using the jumpers.
Clear CMOS: CLEAR_CMOS
The onboard CMOS RAM stores system configuration data and has an
onboard battery power supply. To reset the CMOS settings, set the jumper
on pins 2 and 3 while the system is off. Return the jumper to pins 1 and 2
afterwards. Setting the jumper while the system is on will damage the
mainboard.

PCI Interrupt Request Routing
The IRQ (interrupt request line) are hardware lines over which devices can
send interrupt signals to the microprocessor. The “PCI & LAN” IRQ pins are
typically connected to the PCI bus INT A# ~ INT D# pins as follows:

Note:
ACPI is a power management specification that makes hardware status
information available to the operating system. ACPI enables a PC to turn
its peripherals on and off for improved power management. It also allows
the PC to be turned on and off by external devices, so that mouse or
keyboard activity wakes up the computer.
ACPI Suspend Type
Setting
Description
S1(POS)
S1/Power On Suspend (POS) is a low power state. In this state,
no system context (CPU or chipset) is lost and hardware
maintains all system contexts.
S3/Suspend To RAM (STR) is a power-down state. In this state,
power is supplied only to essential components such as main
memory and wakeup-capable devices. The system context is
saved to main memory, and context is restored from the
memory when a "wakeup" event occurs.
Depends on the OS to select S1 or S3.

The chipset supports synchronous and asynchronous mode between host
clock and DRAM clock frequency.
Settings: [100 MHz, 133 MHz, 166 MHz, 200MHz, 266MHz, By SPD]
DRAM Timing
The value in this field depends on the memory modules installed in your
system.
Changing the value from the factory setting is not recommended
unless you install new memory that has a different performance rating than
the original modules.
Settings: [Manual, Auto By SPD, Turbo, Ultra]
SDRAM CAS Latency [DDR/DDR2]
This item is for setting the speed it takes for the memory module to complete
a command. Generally, a lower setting will improve the performance of your
system. However, if your system becomes less stable, you should change it
to a higher setting. This field is only available when “DRAM Timing” is set to
“Manual”.
Settings: [1.5/2, 2/3, 2.5/4, 3/5]

Bank Interleave
This item is for setting the interleave mode of the SDRAM interface.
Interleaving allows banks of SDRAM to alternate their refresh and access
cycles.
One bank will undergo its refresh cycle while another is being
accessed. This improves performance of the SDRAM by masking the refresh
time of each bank. This field is only available when “DRAM Timing” is set to
“Manual”.
Settings: [Disabled, 2 Bank, 4 Bank, 8 Bank]
Precharge to Active (Trp)
This field is for setting the length of time it takes to precharge a row in the
memory module before the row becomes active. Longer values are safer but
may not offer the best performance. This field is only available when “DRAM
Timing” is set to “Manual”.
Settings: [2T, 3T, 4T, 5T]
Active to Precharge (Tras)
This field is for setting the length of time it a row stays active before
precharging. Longer values are safer but may not offer the best performance.
This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [05T, 06~20T]
Active to CMD (Trcd)
This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [2T, 3T, 4T, 5T]
REF to ACT / REF (Trfc)
This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [08T, 09~71T]
56
BIOS Setup
ACT(0) to ACT(1) (TRRD)
This field is only available when “DRAM Timing” is set to “Manual”.
Settings: [2T, 3T, 4T, 5T]
Read to Precharge (Trptp)
Settings: [2T, 3T]
Write to Read CMD (Twtr)
Settings: [1T/2T, 2T/3T]
Write Recovery Time (Twr)
Settings: [2T, 3T, 4T, 5T]
DRAM Command Rate
This field is for setting how fast the memory controller sends out commands.
Lower setting equals faster command rate.
Note:
Some memory modules may not be able to handle lower settings.
Settings: [2T Command, 1T Command]
RDSAIT Mode
Settings: [Manual, Auto]
RDSAIT Selection
Key in a HEX number.
Settings: [Min = 0000, Max = 003F]
Auto Detect PCI Clk
Settings: [Disabled, Enabled]
CPU Host/PCIEX/AGP/PCI
Settings: [Default, 133/100/66/33MHz, 137/100/68/34MHz,
200/100/66/33MHz, 202/100/67/33MHz, 206/100/68/34MHz,
210/100/70/35MHz]

CPU Clock Ratio
This field is for setting the CPU internal clock multiplier.
Note:
This option does NOT apply to CPU(S) which have this clock multiplier
LOCKED!!
Key in a DEC number.
Settings: [Min = 4, Max = 50]
Spread Spectrum
When the mainboard's clock generator pulses, the extreme values (spikes) of
the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves.
Settings: [Disabled, Enabled]

Change / Set / Disable Password
This option is for setting a password for entering BIOS Setup.
When a
password has been set, a password prompt will be displayed whenever BIOS
Setup is run. This prevents an unauthorized person from changing any part
of your system configuration.
There are two types of passwords you can set. A supervisor password and a
user password.
When a supervisor password is used, the BIOS Setup
program can be accessed and the BIOS settings can be changed. When a
user password is used, the BIOS Setup program can be accessed but the
BIOS settings cannot be changed.
To set the password, type the password (up to eight characters in length)
and press <Enter>.
The password typed now will clear any previously set
password from CMOS memory. The new password will need to be reentered
to be confirmed. To cancel the process press <Esc>.
To disable the password, press <Enter> when prompted to enter a new
password. A message will show up to confirm disabling the password. To
cancel the process press <Esc>.

Additionally, when a password is enabled, the BIOS can be set to request the
password each time the system is booted. This would prevent unauthorized
use of the system. See “Security Option” in the “Advanced BIOS Features”
section for more details.

Driver Installation
This chapter gives you brief descriptions of each mainboard driver and
application. You must install the VIA chipset drivers first before
installing other drivers such as audio or VGA drivers. The applications
will only function correctly if the necessary drivers are already
installed.

DRIVER UTILITIES
Getting Started
The mainboard includes a Driver Utilities CD that contains the driver utilities
and software for enhancing the performance of the mainboard. If the CD is
missing from the retail box, please contact the local dealer for the CD.
Note:
The driver utilities and software are updated from time to time. The latest
updated versions are available at http://www.viaembedded.com/
66
Driver Installation
Running the Driver Utilities CD
To start using the CD, insert the CD into the CD-ROM or DVD-ROM drive.
The CD should run automatically after closing the CD-ROM or DVD-ROM drive.
The driver utilities and software menu screen should then appear on the
screen. If the CD does not run automatically, click on the “Start” button and
select “Run…” Then type: "D:\Setup.exe".
Note:
D: might not be the drive letter of the CD-ROM/DVD-ROM in your system.
