• Auto CPU Throttling Function: Incorporated into this motherboard is a new
technology to enable Pentium 4 processors auto throttling function. When auto
throttling is enabled, the CPU with throttle down to 50% of its duty cycle when
the CPU temperature reaches the threshold and return to 100% of its duty cycle
when temperature lowers to normal level. This function ensures the best
performance and reliability.
• Fan Status Monitoring and Alarm: To prevent system overheat and system
damage, the CPU, PCI, and MAIN fans can be monitored for RPM and failure.
All the fans are set for its normal RPM range and alarm thresholds.
• Temperature Monitoring and Alert: To prevent system overheat and system dam-
age, this motherboard supports processor thermal sensing and auto-protection.
• Voltage Monitoring and Alert: 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
space to present enormous user interfaces and run large applications. The onboard
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” (a.k.a. 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.
• 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, users
can access any information from their computers from anywhere in the world.
• Message LED (requires ACPI OS support): Message LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine if a message has been received from a fax/modem. A simple glimpse
provides useful information to the user. This function requires ACPI OS and
driver support.
• Peripheral Power Up: Keyboard or Mouse power up can be enabled or dis-
abled through BIOS setup to allow the computer to be powered ON using your
keyboard or mouse click.
