dedicated PCI slots, 2 dedicated 16-bit ISA slots and 1 shared PCI/
ISA slot. All PCI and ISA slots are bus masters.
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.

The system board is able to detect the temperature of the
processor. An alarm will sound in case of processor overheat.
Monitors Processor/AGP Fan Speed and Failure Alarm
The system board is able to detect the fan speed (RPM-Revolutions
Per Minute) of the processor and AGP fans, and alerts you to attend
to any irregularity that may damage your system.
Monitors Power Voltages and Failure Alarm
The system board is able to detect the output voltage of the power
supply. An alarm will sound warning you of voltage irregularity.

Introduction
Automatic Fan Control
With the systems power switched on, the processors fan will rotate
only if the temperature of the processor is over 25oC.
Dual Function Power Button (ATX power supply only)
Depending on the setting in the BIOS setup, this switch will allow
your system to enter the Soft-Off or Suspend mode.
External Modem Ring-on (ATX power supply only)
The Modem Ring-on feature allows the system that is in the
Suspend mode or Soft Power Off mode to wake-up/power-on to
respond to incoming calls.
Note:
This feature supports external modem only. If you are using
this function, make sure to turn on the power of the modem
prior to powering-off the system.
RTC Timer to Power-on the System (ATX power supply only)
The RTC installed on the system board allows your system to
automatically power-on on the set date and time.
ACPI (ATX power supply only)
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.
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.

2.3 DIP Switch and Jumper Settings of the
Processors
Make sure SW1 and JP5 are set correctly before applying power or
you may damage the processor or system board. There are 10
switches on SW1. The black rectangle in the diagram denotes the
part that is protruding, the adjustable switch.
In the example on the left:
Switch 1: Off Switch 6: Off
Switch 2: On Switch 7: Off
Switch 3: On Switch 8: Off
Switch 4: On Switch 9: Off
Switch 5: On Switch 10: On
Important:
If you are using a 100MHz ex-
ternal system bus clock processor,
make sure that you use PC-100
SDRAM DIMM ONLY. However,
if you encounter compatibility
problems, we recommend that
you try setting the SDRAM clock
according to the AGP clock (JP4
pins 1 and 2 On). This may help
solve some compatibility
problems.

2.5 Jumper Settings for SDRAM Clock (DIMM)
Jumper JP4
SDRAM Clock
JP4 is used to set the
SDRAMs clock according to
the CPU clock or AGP clock. If
you are using PC-100 SDRAM
DIMMs, it is recommended that
you set the SDRAM clock
according to the CPU clock (2-
3 On). This setting will provide
better system performance
specially when used with 75/
83/95/100MHz processors.
However, if you encounter
compatibility problems with PC-100 SDRAM DIMMs or you are
using EDO / PC-66 SDRAM DIMMs, set the SDRAM clock
according to the AGP clock (1-2 On).
