BIOS
Award BIOS, Windows® 95/98/2000/ME Plug and Play compat-
ible
Supports SCSI sequential boot-up
Flash EPROM for easy BIOS upgrades
Supports DMI 2.0 function
2Mbit flash memory
Desktop Management Interface (DMI)
The system board comes with a DMI 2.0 built into the BIOS. The
DMI utility in the BIOS automatically records various information
about your system configuration and stores these information in the
DMI pool, which is a part of the system board's Plug and Play
BIOS. DMI, along with the appropriately networked software, is
designed to make inventory, maintenance and troubleshooting of
computer systems easier. Refer to chapter 4 for instructions on using
the DMI utility.
1.1.2 System Health Monitor Functions
The system board is capable of monitoring the following system
health conditions.
Monitors CPU/system temperature and overheat alarm
Monitors VCORE/3.3V/5V/12V/2.5V voltages and failure alarm
Monitors CPU/chassis fan speed and failure alarm
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 Intelligence
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.
Introduction

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 2 and Resume On LAN/Ring in the Power
Management Setup section in chapter 3 for more information.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of ≥720mA.
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
On Alarm in the Power Management Setup section in chapter 3 for
more information.
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 2 and Resume On LAN/Ring in the Power Management
Setup section in chapter 3 for more information.
Important:
The 5VSB power source of your power supply must support a
minimum of ≥720mA.

ACPI 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® 98/2000/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® 98/2000/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.
Important:
The 5VSB power source of your power supply must support
≥
1A.
Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table of
your hard disk drive.

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 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.

Hardware Installation
1. Pull the tabs which are at the ends 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.

2.6.4 Floppy Disk Drive Connector
The system board is equipped with a shrouded floppy disk drive
connector that supports two standard floppy disk drives. To prevent
improper floppy cable installation, the shrouded floppy disk header
has a keying mechanism. The 34-pin connector on the floppy cable
can be placed into the header only if pin 1 of the connector is
aligned with pin 1 of the header. You may enable or disable this
function in the Integrated Peripherals submenu of the BIOS.
Connecting the Floppy Disk Drive Cable
1. Install the 34-pin header connector of the floppy disk drive cable
into the shrouded floppy disk header (J12) on the system board.
The colored edge of the ribbon should be aligned with pin 1 of
J12.
2. Install the other 34-pin header connector(s) into the disk drive(s).
Align the colored edge of the daisy chained ribbon cable with pin
1 of the drive edge connector(s). The end-most connector should
be attached to the drive you want to designate as Drive A.
