Introduction

BI S

 Award BIOS, Windows® 95/98/ 000/ME Plug and Play compat-

ible

 Supports SCSI sequential boot-up

 Flash EPROM for easy BIOS upgrades

 Supports DMI .0 function

 Mbit flash memory

 Vcore and CPU external bus clock selectable in the BIOS

Desktop Management Interface (DMI)

The system board comes with a DMI .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 1 V/5V/3.3V/VCORE voltages and failure alarm

 Monitors CPU/chassis fan speed and failure alarm

 Automatic chassis fan on/off control

 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

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

for more information.

ver Voltage

The Over Voltage function allows you to manually adjust to a higher

core voltage that is supplied to the CPU. Although this function is

supported, we do not recommend that you use a higher voltage

because unstable current may be supplied to the system board

causing damage. Refer to CPU-Vcore Select in the Frequency/

Voltage Control section in chapter 3 for more information.

CPU verclocking

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 CPU Host/PCI Clock in the Frequency/

Voltage Control section in chapter 3 for more information.
