Windows95/98/NT . Color-coded connectors and descriptive icons make
identification easy as required by PC’99.
2.1.4 Intelligence
•Fan Status Monitoring and Alarm: To prevent system overheat and system
damage, the CPU, power supply, and system fans can be monitored for RPM
and failure. All the fans are set for its normal RPM range and alarm thresholds.
•Voltage Monitoring andAlert: System voltage levels are monitored to ensure
stable current to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.
•System Resources Alert: Windows 98, Windows NT, and OS/2, require much
more memory and hard disk space to present enormous user interfaces and run
large applications.The onboard hardwareASUSASIC in conjunction with either
the bundled ASUS PC Probe or Intel LDCM, will warn you before the system
resources are used up to prevent possible application crashes.
•Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by”(a.k.a. Suspend or Sleep) button or as the Soft-Off button (see
ATX Power / Soft-Off Switch Lead in 3.8 Connectors for more information).
Regardlessof the setting, pushingthepower button for morethan4seconds allows
the computer to enter the Soft-Off mode.
•Remote Ring On (requires modem): This allows a computer to be turned on
remotely through an internal or external modem. With this benefit on hand, you
can access any information from their computers from anywhere in the world.
•Message LED (requires ACPI OS support): Message LEDs now act as
information providers. Through the way a particular LED illuminates, you can
determine if a message has been received from a fax/modem.A simple glimpse
provides useful information.This function requiresACPI OS and driver support.
•PeripheralPowerUp:Keyboard or Mouse power up can be enabled or disabled
throughBIOS setup to allow the computer to be powered ON using your keyboard
or mouse click.

you should follow some precautions whenever you work on your computer.
1. Unplug your computer when working on the internal components.
2. Use a grounded wrist strap or touch a safely grounded object or to a metal
object, such as the power supply case, before handling computer components.
3. Hold components by the edges and try not to touch the IC chips on them.
4. Whenever you install any component, place the components on a grounded
antistatic pad or in the bag that came with the components.
5. Before you install orremove any component, ensure that theATX power
supply is switched off or the power cord is detached from the power

The motherboard’s onboard functions are either adjusted through jumpers or DIP
switches. When using DIPswitches, the white block represents the switch’s position.
The example below shows all the switches in the OFF position.
1) JumperFree™Mode (JEN)
This jumper allows you to enable or disable the JumperFree™mode. The
JumperFree™mode allows processor settings to be made through the BIOS
setup (see 4.4 Advanced Menu).
NOTE: In JumperFree™mode, all dip switches must be set to OFF.

2) USB Device Wake Up (USBPWR1,USBPWR2)
These allow you to disable or enable the USB device wake up function. Set these
jumpers to Enable if you wish to use your USB devices to wake up your computer.
ThisfeaturerequiresanATXpowersupplythatcansupply atleast 2Aonthe +5VSB
lead. The default is set to Disable because not all computers have the appropriate
ATX power supply. Your computer will not power ON if you set this to Enable and
do not have the appropriateATX power supply. NOTE: This jumper must be set in
conjunction with Wake On USB for STR State in 4.5.1 Power Up Control.
NOTES
1. For suspend to RAM function, these jumpers must be set to Enable.
2. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal working conditions or in the sleep mode.
3) CNR/USB Selection (CNRUSB1/CNRUSB2)
The CNR slot can support an optional USB hub CNR card. If a USB hub CNR
card is used, set these jumpers to CNR. Otherwise, leave them on the default
setting of USB2 Connect.
