damage, the CPU, PWR, and CHASSIS fans can be monitored for RPM and
failure. All the fans are set for its normal RPM range and alarm thresholds.
•TemperatureMonitoringandAlert:To preventsystemoverheatandsystemdam-
age, this motherboard supports processor thermal sensing and auto-protection.
•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: Today’s operating systems, such as Windows 98/
Millenium, and Windows NT/2000, require much more memory and hard drive
spaceto present enormous userinterfaces and run large applications.Theonboard
hardware ASUS ASIC in conjunction with either the bundled ASUS PC Probe
or Intel LDCM will warn the user before the system resources are used up to
prevent possible application crashes. Suggestions will give the user information
on managing their limited resources more efficiently.
•Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by”(ie.: Suspend or Sleep) button or as the Soft-Off (see ATX
Power / Soft-Off Switch Lead in 3.8 Connectors for more information) button.
Regardless of the setting, pushing the power button for more than 4 seconds will
enter the Soft-Off mode.

orientation. The gold arrow of
the CPU must be oriented to-
ward the outer corner of the
socket base nearest to the tip of
the lever handle.
3. Once completely inserted, press the CPU firmly and close the socket
lever until it snaps into its locked position.
CAUTION! The CPU fits in one orientation and should drop easily into
place. Do not force the CPU into the socket to avoid bending the pins. If
the CPU does not fit, check its alignment and look for bent pins.
