CPU Warning Temperature
This item selects the CPU's warning temperature limit. Once the system has detected
that the CPU's temperature exceeded the limit, warning beeps will sound.
NOTE: The onboard hardware monitor function is capable of detecting these system
health conditions. If you want a warning message to pop-up or a warning alarm to
sound when an abnormal condition occurs, you must install the "Hardware Doctor"
utility. This utility is included in the "Driver & Utility CD" that came packed with this
motherboard.
Case-Open Detection
This option controls the function for case-opening detection device connected at pin-7
and pin-8 at FPIO1 header.
[Disabled]: Disable the Case-Open Detection.
[Enabled]: Enable the Case-Open Detection.
[Cleared]: Clear the warning message when the case-opening situation is detected.
Warning Beep
This option controls the onboard buzzer to beep when the case-opening situation is
detected.
All Voltages, Fans Speed and Thermal Monitoring
These unchangeable items list the current status of the CPU and environment
temperatures, fan speeds, and system power voltage.
NOTE: The hardware monitoring features for temperatures, fans and voltages will
occupy the I/O address from 294H to 297H. If you have a network adapter, sound
card or other add-on cards that might use those I/O addresses, please adjust your
add-on card I/O address to avoid using these addresses.
