Desktop Management Interface (DMI)
The system board comes with a DMI .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.
1.1.2 System Health Monitor Functions
The system board is capable of monitoring the following “system
health” conditions.
• Monitors CPU/system temperature
• Monitors ±1 V/±5V/3.3V/CPU/VBAT(V)/5VSB(V) voltages
• Monitors CPU/chassis fan speed
• Automatic chassis fan on/off control
• Read back capability that displays temperature, voltage and fan
speed
Refer to the “PC Health Status” section in chapter 3 and the
“Hardware Monitor” section in chapter 4 for more information.
1.1.3 Intelligence
CPU Temperature Protection
The CPU Temperature Protection function has the capability of
monitoring the CPU’s temperature during system boot-up. Once it
has detected that the CPU’s temperature exceeded the CPU
temperature limit defined in the BIOS, the system will automatically
power-off after 5 warning beeps. Refer to “CPU Temp. Prot. Function
and CPU Temp. Prot. Alarm” in the PC Health Status section in
chapter 3 for more information.
