The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. It
supports peripheral devices that meet the HPSIR and ASKIR
standard.
USB Ports
The system board supports 4 USB ports. Two onboard USB ports
are located at the ATX double deck ports of the board. The J15
connector on the system board allows you to connect more
optional USB ports. These optional USB ports, which are mounted
on a card-edge bracket, will be provided as an option. USB allows
data exchange between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals.

 Read back capability that displays temperature, voltage and fan
speed
Refer to the PC Health Status section in chapter 3 and the VIA
Hardware Monitor section in chapter 4 for more information.
1.1.3 ntelligence
CPU Temperature Protection
The CPU Temperature Protection function has the capability of
monitoring the CPUs temperature during system boot-up. Once it
has detected that the CPUs temperature exceeded the CPU
temperature limit defined in the BIOS, the system will automatically
power-off after 5 warning beeps. Refer to CPU Temp. Prot. Function
and CPU Temp. Prot. Alarm in the PC Health Status section in
chapter 3 for more information.
CPU Fan Protection
The CPU Fan Protection function 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. This
preventive measure has been added to protect the CPU from
damage and insure a safe computing environment. Refer to CPU
Fan Connector with CPU Fan Protection Function in chapter and
CPU Fan Protection in the PC Health Status section in chapter 3

CPU Overclocking
The CPU Overclocking function allows you to adjust the processors
bus clock. However, overclocking may result to the processors or
systems instability and are not guaranteed to provide better system
performance. Refer to Clock By Slight Adjust in the Frequency/
Voltage Control section in chapter 3 for more information.
Automatic CPU/Chassis Fan Off
The CPU and chassis fans will automatically turn off once the system
enters the Suspend mode.
Dual Function Power Button
Depending on the setting in the Soft-Off By PWRBTN field of the
Power Management Setup, this switch will allow the system to enter
the Soft-Off or Suspend mode.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
through an internal or external modem. Refer to Wake-On-Ring
Connector in chapter and Resume On LAN/Ring (Wake Up
Events field) in the Power Management Setup section in chapter 3
for more information.
mportant:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of ≥ 720m .
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time. Refer to Resume

Wake-On-LAN
The Wake-On-LAN function allows the network to remotely wake
up a Soft Power Down (Soft-Off) PC. Your LAN card must support
the remote wakeup function. Refer to Wake-On-LAN Connector in
chapter and Resume On LAN/Ring (Wake Up Events field) in
the Power Management Setup section in chapter 3 for more
information.
mportant:
The 5VSB power source of your power supply must support a
minimum of ≥ 720m .
AC Power Failure Recovery
When power returns after an AC power failure, you may choose to
either power-on the system manually, let the system power-on
automatically or return to the state where you left off before power
failure occurs. Refer to PWR Lost Resume State in the Power
Management Setup section in chapter 3 for more information.
ACP STR
The system board is designed to meet the ACPI (Advanced
Configuration and Power Interface) specification. ACPI has energy
saving features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct
Power Management. Currently, only Windows® 98/ 000/ME supports
the ACPI function allowing you to use the Suspend to RAM function.
With the Suspend to RAM function enabled, you can power-off the
system at once by pressing the power button or selecting Standby
when you shut down Windows® 98/ 000/ME without having to go
through the sometimes tiresome process of closing files, applications
and operating system. This is because the system is capable of
storing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The
operating session will resume exactly where you left off the next time
you power-on the system. Refer to Using the Suspend to RAM
Function in appendix A for more information.
mportant:
The 5VSB power source of your power supply must support

2.2 System Memory
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.
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.

Hardware nstallation
Refer to chapter 1 (System Memory section) for detailed
specification of the memory supported by the system board.
1. Pull the tabs which are at the ends of the socket to the side.
. 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.

 The frequency ratio of some processors shown in the table
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.
 Most processors with frequency ratio greater than 8x have
locked frequency ratio therefore does not have the flexibility
of using extended ratio. If your processor does not have
locked frequency ratio, you can set SW1 according to the
desired ratio.
 The processors supported by the system board support
VID (Voltage Identification). The switching voltage regulator
on the system board will automatically set the voltage
regulator according to the voltage of the processor.
